Description

Technical Field

[0001] This invention belongs to the fields of clinical medical device technology and home rehabilitation exercise, specifically referring to a leg swing rehabilitation training support frame and training device. Background Technology

[0002] The world has entered an aging society, and the proportion of the elderly population continues to increase year by year. Knee osteoarthritis has become one of the leading causes of disability worldwide, seriously affecting the quality of life of the elderly. As of the end of 2018, statistics show that more than 60% of people aged 65 and above suffer from knee pain, and the number of patients with knee osteoarthritis has reached more than 120 million. China is one of the countries with the largest number of people suffering from knee osteoarthritis.

[0003] The knee joint is the most complex weight-bearing joint in the human body and one of the most susceptible to disease. Knee joint disorders are usually caused by a series of pathophysiological changes within the joint cavity, including arthritis, osteoarthritis, synovitis, patellar chondromalacia, meniscus injury, subchondral bone sclerosis, osteoporosis, collapse, and cystic hollowing, due to various factors such as lower limb biomechanics instability, disuse atrophy of the lower limbs, incorrect posture during long-term work and life (such as prolonged sitting or squatting), chronic coldness and insufficient blood supply to the lower limbs, intra-articular infection, primary and metastatic cancerous lesions within the joint cavity, endocrine disorders, osteoporosis, and exogenous high-energy injury. Knee osteoarthritis (KOA), also known as proliferative knee arthritis or senile knee arthritis (commonly known as "old cold legs"), is a common chronic joint disease characterized by functional and morphological degeneration. The earliest and most significant pathological changes are in the cartilage, followed by subchondral bone cysts, osteophyte formation at the joint margins, and finally complete destruction and deformity of the normal articular surface, leading to increased pain, limited mobility, and even disability.

[0004] Modern clinical medicine has proposed different treatment plans for KOA patients at different stages of the KL (Kellgren-Lawrence) classification. Total knee replacement surgery (TKA, UKA) is another major treatment method applied to KOA patients who have reached the fourth stage of the clinical KL classification. However, this type of surgery is a destructive and reconstructive surgery, which is relatively invasive and has low patient acceptance. At the same time, after knee replacement surgery, the strength of the muscles around the knee joint and the sensitivity of the lower limb proprioceptors cannot meet the needs of normal daily life and movement. In particular, the entire proprioceptor system of the lower limb is damaged, which sows the seeds of endless trouble for future falls in normal life.

[0005] Currently, the "Chinese Clinical Practice Guidelines for Osteoarthritis Pain Management (Chinese Journal of Orthopaedics 2020 Edition)" lists exercise therapy as a 1A (strong recommendation, highest level) option for treating KOA, instructing patients to perform leg-swinging exercises. Leg-swinging can effectively treat knee pain and help patients recover quickly. However, the exact mechanism by which leg-swinging effectively treats knee pain has not been clearly elucidated for a long time. In the patent document CN113952677B, entitled "Treatment and Rehabilitation Device for Knee Joint Degenerative Diseases Based on KOAPT Therapy," inventor Mr. Song Jiuhong first discovered that leg-swinging exercises can drive non-contact movement of the upper and lower joint surfaces of the knee joint and contraction and relaxation movements of the synovial bursa around the knee joint cavity through hip joint swinging; this secondarily causes the intra-articular pressure to increase and decrease in stages and alternately; thereby promoting the secretion and absorption of synovial fluid in the joint cavity; thus effectively removing various inflammatory factors and pain factors from the joint cavity; and because of the increased circulation of synovial fluid, it promotes a positive repair trend of articular cartilage; overall, it alleviates the symptoms of knee joint pain and provides a valuable pathophysiological basis for the repair of damaged articular cartilage. Furthermore, the patent literature first defined the Knee Osteoarthritis Pendulum Therapy (KOAPT) based on this scientific discovery and introduced a corresponding pendulum-style leg-swinging rehabilitation training device. In particular, the patent literature first proposed the scientific concept of "correct-comfort ratio" (a proper ratio between correct and comfortable). To achieve this "correct-comfort ratio," the support components need to support the user's limbs and reduce weight during leg swings, thereby reducing the load on a single weight-bearing leg and achieving comfortable and sustainable leg-swinging exercise. By combining the training device with KOAPT therapy, it can secondaryly induce a phased increase and decrease in intra-articular pressure, promoting the secretion of synovial fluid and effectively relieving knee pain symptoms. Simultaneously, it efficiently trains the strength of the leg's flexor and extensor muscles and significantly improves the sensitivity of lower limb proprioceptors. However, existing leg-swinging rehabilitation devices are complex in structure, costly, space-consuming, and inconvenient for widespread use by patients. The inventors of this application discovered, through further in-depth research, that existing treatment and rehabilitation equipment still has shortcomings:

[0006] Firstly, the standardization of leg-swinging movements in KOAPT therapy is a crucial factor closely related to treatment effectiveness. Users often cannot determine whether their leg-swinging motion is up to standard, frequently neglecting the height of the swing, leading to inconsistent and non-standard movements and ultimately poor treatment results. Existing treatment and rehabilitation equipment uses photoelectric sensors or cameras to collect signals from the patient's leg-swinging movements. While signal analysis determines whether the swinging motion meets amplitude requirements, the collected signals are subject to acoustic and optical interference, resulting in inaccurate analysis results.

[0007] In addition, when users complete the leg-swinging exercise, while ensuring that their body posture is vertical and their weight loss is achieved, their hands can be freed to complete other tasks. This poses new requirements for the design of leg-swinging rehabilitation training equipment. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention proposes a leg-swinging rehabilitation training support frame and training equipment, which helps users provide timely feedback on their leg-swinging progress during KOA leg-swinging rehabilitation treatment and enables patients to perform other activities while training their legs.

[0009] To achieve the above objectives, the present invention provides a leg-swinging rehabilitation training support frame, comprising a base, a support frame, and a leg-swinging target belt. One end of the support frame is connected to the base, and the other end is provided with a support platform. The base is provided with a standing area. The support platform includes an open receiving opening. The components on both sides of the receiving opening on the support platform are support parts. The receiving opening is located above the standing area. The two ends of the leg-swinging target belt are installed on the target belt support frame. The leg-swinging target belt is horizontally positioned above the front side and / or above the rear side of the standing area on the user's leg-swinging path. When the user swings their leg and touches the leg-swinging target belt, the leg-swinging target belt provides feedback of a target achievement signal.

[0010] When users perform leg-swinging exercises, they typically swing their legs forward and / or backward in a pendulum-like motion to decrease or increase joint pressure, thereby promoting the secretion of synovial fluid and effectively relieving knee pain symptoms. Therefore, for users performing leg-swinging rehabilitation exercises, whether the leg is swung forward and upward and / or backward and upward to the predetermined target position is the standard requirement for whether the leg-swinging rehabilitation training is met. Therefore, users can pre-set target strips along the leg-swinging path above the front and / or above the back, based on the KOAPT therapy's requirements for leg-swinging amplitude and their own achievable leg-swinging position. Each time a user swings their leg, they aim to touch the target strip, ensuring the leg-swinging height and effectively improving consistency and standardization. Furthermore, when a user touches the target strip, it provides a feedback signal, such as a tactile, auditory, visual, or photoelectric digital signal. Upon receiving this signal, the user knows that the leg-swinging motion has met the target. If the target is not met, no feedback signal is received, and the user knows that the leg-swinging motion has not met the target and adjusts their next swing to touch the target strip. This setup improves the effectiveness and standardization of the leg-swinging exercise. Moreover, this continuous feedback and feedback can psychologically boost the user's confidence in being noticed and recognized, making the seemingly monotonous leg-swinging exercise, which requires nearly a thousand repetitions, more interesting and sustainable.

[0011] Furthermore, the vertical distance between the leg-swinging target belt and the upper surface of the base is 10-120cm. By adopting the above technical solution, the height of the leg-swinging target belt from the upper surface of the base varies depending on factors such as different user heights, leg-swinging abilities, and requirements. However, this distance range is the optimal range for enabling users to swing their legs with the target belt as the goal, improving the consistency and standardization of leg-swinging.

[0012] Furthermore, it also includes a counting sensor, with its sensing head facing the user's leg-swinging path. By adopting the above technical solution, the counting sensor records the number of times the user swings their legs, improving the intelligence of the device.

[0013] Furthermore, the sensing heads of the counting sensor are located at both ends of the leg-swinging target belt. By adopting the above technical solution, the counting sensor and the leg-swinging target belt are linked. The counting sensor is located at both ends of the leg-swinging target belt. When the user swings their leg and touches the target belt, the user receives a feedback signal indicating that they have met the target. At the same time, the counting sensor records this successful leg swing. The final recorded number is the number of successful leg swings, improving the convenience of the device.

[0014] Furthermore, the support frame is configured in pairs, located on either side of the standing area. Each support frame includes two connecting rods, one end of which is fixedly connected to the support frame, and the free ends of the two connecting rods are fixedly connected to both ends of the leg-swinging support belt. By adopting the above technical solution, the leg-swinging support belt is fixedly mounted on the support frame via the connecting rods, resulting in strong connection stability, a compact structure, and convenient installation. This allows users located on one side of the support frame to pre-set the leg-swinging support belt along their leg-swinging path before swinging their legs.

[0015] Furthermore, an adjusting shaft is provided at the connection between the connecting rod and the bracket, and the connecting rod rotates around the axis of the adjusting shaft. By adopting the above technical solution, the connecting rod can be adjusted by rotating in an arc to adjust the height of the leg-swinging standard belt from the upper surface of the base, thereby adapting to the usage requirements of different users' heights, leg-swinging abilities, and needs, improving the flexibility and application range of the device. The adjusting shaft can be any existing structure that can adjust the angle via a shaft, such as a damping shaft, a damping hinge, or a damping hinge.

[0016] Furthermore, the standard-setting belt support includes a fixing frame, which is disposed on the outside of the support. The bottom of the fixing frame is fixed to the ground or a base, and the top has two spaced-apart ends. The two ends of the leg-swinging standard-setting belt are correspondingly and fixedly connected to the two ends of the fixing frame. By adopting the above technical solution, the placement of the leg-swinging standard-setting belt is more flexible due to the separately set standard-setting belt support. The fixing frame can be an adjustable structure with a telescopic rod, which facilitates the vertical adjustment of the vertical distance between the leg-swinging standard-setting belt and the upper surface of the base plate, thereby adjusting the height of the leg swing.

[0017] Furthermore, the leg-swinging achievement belt is rotatably connected to the achievement belt bracket about its extension direction. By adopting the above solution, the angle of the leg-swinging achievement belt can be adjusted to maximize the contact area between the leg-swinging achievement belt and the user's leg when swinging, thereby improving the strength of the achievement signal fed back to the user or the accuracy of sensor recognition.

[0018] Furthermore, the leg-swinging target belt is a tangible object, which can be one or more of the following: a damping rope, a damping band, a damping net, an elastic band, a bell, or a kickboard. By adopting the above solution, the leg-swinging target belt is a tangible, touchable object. When the user swings their leg and touches the target belt, the tangible nature of the belt itself provides tactile feedback to the user, giving them a tactile signal indicating compliance. Moreover, the tangible, flexible target, especially a damping band, provides a rebound, assisting the user in swinging their leg, reducing the difficulty of the leg swing, and improving its efficiency.

[0019] Furthermore, the leg-swinging achievement zone is a visible target, which can be a visible light beam or a visible video signal, specifically a visible light strip of a visible light beam or video signal. By adopting the above technical solution, the visible target can be a visible light beam or a visible video signal image. When the user touches the visible light beam or the visible video signal, the visible light beam or the visible video signal changes to an incomplete state, providing the user with a visual signal of achievement. This setting does not occupy space, making it easy for users to pass through the leg-swinging achievement zone to enter or leave the standing area, improving the convenience and technological fun of the device.

[0020] Furthermore, the leg-swinging achievement belt is a sensing strip for a photoelectric sensor and also includes a feedback component. The feedback component is electrically connected to the photoelectric sensor and emits audio and / or video and / or visible light and / or tactile signals to the user based on the signal from the photoelectric sensor. By adopting the above technical solution, the leg-swinging achievement belt uses a non-visual sensor method. When the user touches the sensing area of ​​the photoelectric sensor, the photoelectric sensor emits a signal to the feedback component. After receiving the signal, the feedback component emits an audio or video signal indicating that the user has achieved the standard, such as a "beep," "achieved the standard," or "great job," providing feedback to the user. The feedback signal is more direct and clear, further enhancing the standard reference, feedback, and incentive functions of the leg-swinging achievement belt without occupying space. This allows users to clearly understand their achievement status, adjust their leg-swinging movements in a timely manner, improve the standardization of leg-swinging, and boost user confidence.

[0021] Furthermore, the feedback component is a video signal playback element and / or an audio signal playback element and / or a vibration feedback element and / or a visible light emitting element. This is the specific structure for implementing the feedback component to emit audio and / or video and / or visible light signals and / or tactile signals to the user.

[0022] Furthermore, a foot pedal is provided on the base, and the foot pedal is located above the standing area. The foot pedal can be set as a single-leg foot pedal, allowing the user to stand on one leg while the other leg is suspended in the air, making it easier to perform leg swinging exercises.

[0023] Furthermore, the support portion is equipped with an upper limb support bracket, which is one or more of a rubber pad, fiber pad, sponge pad, flexible plastic pad, and metal sheet. This improves the user's comfort during weight reduction support.

[0024] Furthermore, a grip handle is provided on the support platform, and the grip handle is located on the front side of the support. The grip handle improves the support stability of the device and the user's comfort.

[0025] Furthermore, the support platform is equipped with a guide handle, which is located at the end of the support unit near the user. The guide handle is used to guide and support the user when entering the standing area, helping the user to adjust their posture more quickly.

[0026] In one embodiment, the base includes a base plate, the bracket includes a vertical bracket, the support platform includes a support plate, the support plate includes a U-shaped opening, one end of the vertical bracket is connected to the middle of the base plate, the standing area includes a single-leg standing area, the base plate located on both sides of the vertical bracket is configured as the single-leg standing area, the other end of the vertical bracket is fixedly connected to the bottom of the support plate, and an upper limb support area is correspondingly configured on the support portion of the support plate, the upper limb support area is correspondingly arranged on the same side as the single-leg standing area, and the upper limb support area is arranged on both sides of the U-shaped opening.

[0027] By adopting the above technical solution, the device forms a double "C" shape structure around the vertical support located in the middle of the base plate, both front and back, and left and right. This frees up the lateral space between the base plate and the support plate, saving space and making it more suitable for a wider range of users. Furthermore, the double "C" shape structure provides high mechanical stability. When the user's upper limbs are supported in the upper limb support area and their legs are standing in the standing area while swinging their legs, the "C" shape structure formed by the support plate, vertical support, and base plate effectively ensures the overall stability of the device during the user's leg swing. The arrangement of the upper limb support area on both sides of the receiving opening helps the user maintain a correct upright standing posture, improving the standardization of leg swing. The arrangement of the upper limb support areas on both sides effectively increases the stress area of ​​the support plate and disperses the stress points of the support plate, resulting in less support pressure on the support plate and further improving support stability.

[0028] In another embodiment, the base includes a base plate, the bracket includes a vertical bracket, the support platform includes a support plate, the support plate includes a U-shaped opening, one end of the vertical bracket is connected to the side of the base plate located on the left or right side of the standing area, the standing area of ​​the base plate and the upper limb support area of ​​the support plate are both configured to be located on one side of the vertical bracket, the upper limb support area, the standing area and the U-shaped opening are arranged on the same side relative to the single vertical bracket, and the upper limb support area is arranged on both sides of the U-shaped opening.

[0029] By adopting the above technical solution, the structure of the single vertical bracket located on the side of the base plate makes the base plate, the single vertical bracket, and the support plate form a large "C" shape structure. The lateral space between the base plate and the support plate is released to the maximum extent, saving space. In addition, when in use, the single vertical bracket can be placed against the wall to maximize the space-saving advantage of the device. The device has high support stability and is convenient for transportation and manufacturing.

[0030] Preferably, the base plate is provided with a leg partition, the single-leg standing area is located on both sides of the leg partition, and the leg partition is located below the U-shaped opening.

[0031] By adopting the above technical solution, when the user stands in the receiving port, the leg partition below the receiving port has already separated the user's left and right legs in advance. When swinging the legs, the user can swing the legs directly along the preset leg partition, which not only guides the user to swing the legs along the correct leg swing path, but also avoids the user's irregular leg swings such as swinging the legs horizontally or diagonally, improves the standardization of leg swings, and reduces the probability of kicking the upright support during the leg swing process, making the leg swing smooth, unobstructed, and sustainable.

[0032] Preferably, the vertical support includes a telescopic adjustment device for vertical adjustment, and the working end of the telescopic adjustment device is fixedly connected to the bottom of the support plate. By adopting the above solution, the vertical adjustment function of the vertical support is achieved.

[0033] Preferably, a foot pedal box is provided on the base plate. The foot pedal box is located below the support plate and on one side of the vertical bracket, which makes it convenient for the user to stand on one foot pedal with the other foot hanging in the air, making it easier to perform leg swinging exercises.

[0034] Preferably, the base plate is provided with a guide rail, the two ends of the guide rail are respectively located on both sides of the vertical bracket, and the foot pedal box is slidably installed on the guide rail, which facilitates the switching of left and right feet.

[0035] In another embodiment, the base plate is a base plate on which a lifting pedal assembly is mounted. By adopting the above solution, the two lifting pedals in the lifting pedal assembly can be intermittently alternately raised and lowered, allowing the user to alternately switch between the support leg and the swing leg.

[0036] In another embodiment, the bracket includes a side support plate, the support platform includes a lifting platform, a vertically arranged side support plate is provided on one side of the base plate, the lifting platform is mounted on the upper surface of the side support plate, and a middle partition plate is provided in the middle of the base plate, with a seat support device at the upper end of the middle partition plate for sitting or leaning. In this embodiment of the side support plate, the middle partition plate can separate the left and right legs, guiding the user to swing their legs correctly in the direction of walking. Furthermore, the seat support device allows for sitting while swinging the legs, improving the convenience of leg swinging.

[0037] In another embodiment, the lifting platform includes a fence panel with an inverted U-shaped cross-section. An inverted U-shaped support platform for supporting the elbow is fixed to the upper surface of the fence panel. A cantilever support connected to an underarm support device is fixed to the lower surface of the inverted U-shaped support platform and inside the fence panel. A telescopic column is fixed to one side of the cantilever support. The telescopic end of the telescopic column is fixedly connected to the cantilever support, and the base end of the telescopic column is fixedly connected to the side upright plate. This improves the stability of the support platform.

[0038] In another embodiment, the side panel includes a side panel shell and a side panel cover. The side panel shell includes vertically arranged reinforcing ribs with a U-shaped cross-section. The base end of the telescopic column is embedded in the U-shaped groove of the reinforcing rib. The bottom end of the reinforcing rib extends inward to a base fixing connection end embedded in the base. The geared motor of the electric lifting column is sleeved inside the base fixing connection end. The specific structure of the side panel effectively realizes the telescopic function, and the structure is compact and highly integrated.

[0039] In another embodiment, the lifting platform is equipped with an elbow support rod. One end of the elbow support rod is hinged to the platform surface, and the other end is hinged to one end of the upper limb support bracket. The other end of the upper limb support bracket is hinged to the lifting platform. The opening between the left and right upper limb support brackets can be adjusted using a damping rod, making it suitable for users of different body widths and providing high flexibility.

[0040] In another embodiment, the support platform is provided with side handles, which are located on the outer side walls on the left and right sides of the support platform.

[0041] In another embodiment, an inverted U-shaped front railing grip support is also included for gripping and holding. The front railing grip support is an inverted U-shaped support railing that is fixedly installed in front of the lifting platform. It can be used as an auxiliary support to further balance and stabilize the user's body while the user can support their body weight with their elbow.

[0042] In another embodiment, an underarm support is also included. The underarm support is mounted on the underarm support device, which uses an electric rod for automatic lifting and lowering. The electric rod includes a vertically arranged electric rod that is fixedly connected to the side of the lifting platform. A telescopic rod is provided inside the electric rod. Arc-shaped axillary support plates are provided on the left and right sides of the telescopic rod. The axillary support plates are connected to the telescopic rod through an axillary support plate pivot at the upper end of the telescopic rod, so that the axillary support plates can rotate inward and outward around the axillary support plate pivot to accommodate patients of different body types.

[0043] In another embodiment, a seat support device is provided on the substrate, the seat support device is located below the U-shaped opening of the inverted U-shaped support platform, and the upper end of the seat support device is provided with a seat support area to support the user's buttocks.

[0044] Furthermore, the seat support device includes a Γ-shaped seat switching device, which is equipped with a seat support that can be flipped up and down and moved back and forth relative to each other. When the seat support is flipped up, the seat support is in a buttock-leaning state, and when the seat support is laid flat, the seat support is in a buttock-sitting state. The seat switching device is connected to a seat support lifting device arranged on the middle partition and capable of being raised and lowered through a lifting tube at its lower end. The rear end of the seat support lifting device is equipped with a locking valve for locking or releasing the lifting tube.

[0045] Furthermore, the seat-back switching device includes a toothed horizontal limiting plate at the upper part of the Γ-shape and a lifting tube at the lower part of the Γ-shape. The toothed horizontal limiting plate has sliding grooves arranged front and back on both sides, and a damping slider shaft matching the sliding groove is provided in the sliding groove. The seat support lifting device includes a seat support lifting tube column set on the middle partition plate. The seat support lifting tube column adopts an electric rod automatic control lifting method or a manual pressure adjustment and tightening method.

[0046] The present invention also proposes a knee joint rehabilitation training device, including the above-mentioned leg swing rehabilitation training support frame.

[0047] This invention helps patients perceive whether each leg swing is meeting the target standard during the KOAPT leg swing exercise. By placing a target swing band along the user's leg swing path at the upper front and / or upper back, the user aims to touch the target band with each swing, ensuring the height of the swing and effectively improving consistency and standardization. Furthermore, when the user touches the target band, the band provides a signal indicating that the swing was performed correctly. If the target is not met, no signal is received, indicating that the swing was not performed correctly. This continuous feedback boosts the user's confidence, making the seemingly monotonous leg swing exercise (requiring nearly a thousand repetitions) more interesting and sustainable.

[0048] The installation position of the leg-swinging target belt proposed in this invention is related to the position of the user's standing area when swinging their legs. Before use, the user sets the vertical height between the leg-swinging target belt and the base according to the leg-swinging amplitude requirements corresponding to a certain stage of the KOAPT therapy and their own height and leg length characteristics. Then, the height and orientation of the leg-swinging target belt are set to adapt to the height and angle of their own leg swinging through the adjustment device.

[0049] The leg-swinging rehabilitation training support frame designed in this invention has multiple support methods, providing users with different leg-swinging exercise experiences while meeting the requirements of support and weight reduction. In addition, the height of the support frame is adjustable, making it suitable for users of different body types, and the device is highly flexible. Attached Figure Description

The components on both sides of the receiving opening 31 on the support platform 3 are support parts 32, located above the receiving opening 31 and positioned above the standing area 4. Both ends of the leg-swinging target-achieving belt 5 are mounted on a target-achieving belt support 6. The leg-swinging target-achieving belt 5 is horizontally positioned above the front and / or rear of the standing area 4 on the user's leg-swinging path. When the user swings their legs and touches the leg-swinging target-achieving belt 5, the leg-swinging target-achieving belt 5 provides a target-achieving signal.

[0074] In this embodiment, the base 1 provides a corresponding standing space for the user, and the support platform 3 above is connected to the bracket 2 connected to the base 1. The user can stand on one leg on the base 1 and support himself / her forearm or arm on the support platform 3 to maintain a stable standing posture. With his / her own strength or the help of other assistive devices, he / she swings the affected leg. When the swinging leg passes the upper front and / or upper back of the standing area 4 and touches the swinging target belt 5, the swinging target belt 5 sends a feedback signal indicating that he / she has completed a swinging movement that meets the standard swinging amplitude.

[0075] Example 2:

[0076] This embodiment proposes a preferred implementation scheme compared to Embodiment 1, wherein a foot pedal 8 is provided in the standing area 4 on the base 1. It also includes counting sensors, which are located at both ends of the leg-swinging target belt 5, with the sensing head 7 facing the user's leg-swinging path, for collecting the number of leg swings by the user.

[0077] The vertical distance between the leg-swinging target belt 5 and the upper surface of the base 1 is 10-120cm. This invention collected experimental data from users of different heights and body types undergoing KOAPT exercise therapy. After measurement and analysis, the following results were obtained: For individuals with a height range of 155cm-185cm, the forward leg swing parameters are: L1: 10-50cm, D1: 50-85cm, angle: 35-60 degrees; the backward leg swing parameters are: L2: 10-30cm, D2: 45-65cm, angle: 25-45 degrees. L represents the height difference between the heel and the leg-swinging target belt 5, and D represents the horizontal distance between the heel and the leg-swinging target belt 5. Therefore, a vertical distance of 10-120cm between the leg-swinging target belt 5 and the upper surface of the base 1 is a reasonable range for achieving the required leg-swinging amplitude, with 10-50cm being the most effective range.

[0078] The leg-swinging target belt 5 can adopt a physical structure that can be touched, including one or more of the following: damping rope, damping belt, damping net, elastic rubber band, bell, and kicking plate. The connecting rope for the bell and kicking plate is connected to the two ends of the connecting rope to the target belt bracket 6. When the leg is swung, the user kicks the bell or kicking plate hanging on the connecting rope to obtain tactile or even sound feedback. Alternatively, it can be directly set in a designated position through other fixed objects so that the user can obtain tactile or even sound feedback after touching it.

[0079] The leg-swinging target belt 5 can also be achieved through a visible target object, including a visible light strip or a visible video signal. When the user swings their leg to reach the target height, they touch the sensing strip of the leg-swinging target belt 5, which is either a visible light strip, a visible video signal, or a photoelectric sensor. This causes the sensing strip of the visible light strip, the visible video signal, or the photoelectric sensor to be blocked or deformed, serving as a feedback signal that the target has been achieved.

[0080] The leg-swinging achievement belt 5 can also be a sensing belt for a photoelectric sensor. In this embodiment, it also includes a feedback component, which is electrically connected to the photoelectric sensor. The feedback component sends audio and / or video and / or visible light and / or tactile signals to the user based on the signal from the photoelectric sensor. The feedback component serves as an enhanced representation of the achievement signal, more clearly conveying the achievement signal to the user. The feedback component can be a video signal playback element and / or an audio signal playback element and / or a vibration feedback element and / or a visible light emitting element.

[0081] The counting sensor can be implemented using a photoelectric sensor, a TOF sensor, or other sensors to collect the number of times a user swings their leg. The user swings their leg twice, passing through the sensor's detection area twice, which is considered one leg swing. The leg swing frequency acquisition device can be set up independently or reused from the leg swing count acquisition device. The leg swing frequency is calculated by converting the number of leg swings collected by the counting sensor with the corresponding time. The leg swing amplitude acquisition device can be implemented by setting up a photoelectric sensor at a position that meets the standard for leg swing amplitude to collect photoelectric signals.

[0082] Feedback components are used to send audio and / or video and / or tactile signals to the user based on control commands. Feedback components can be displays, speakers, massage heads, motors, etc., mounted on the motion support component, sending image information, sound information, massage vibrations, or driving the movement of the support component according to control commands. Feedback components can also be integrated into mobile devices, where the mobile device sends image information, sound information, etc., according to control commands.

[0083] This embodiment also includes a control device deployed with the KOAPT computer program. The control device, implemented via a computer chip, collects the user's exercise data in real time and guides the user to complete rehabilitation training according to the KOAPT treatment model. The control device includes a communication module, a power module, and an analysis module. The communication module can use transmission methods such as Wi-Fi or Bluetooth. The control device can be mounted on the support platform 3 and interact with the user through a human-computer interactive display screen. Alternatively, it can be remotely mounted on a server and communicate with the user via a mobile device, or the server can directly send control commands to the feedback component.

[0084] In a preferred embodiment, there are two leg-swinging target belts 5, which are horizontally arranged above the front and rear sides of the user's leg-swinging path, respectively. When the user swings their legs, they touch the front and rear leg-swinging target belts 5, and the front and rear leg-swinging target belts respectively feed back a target signal. After the sensing heads 7 of the front and rear counting sensors collect the counting signal, the control device receives the counting signal collected by the sensing heads 7 of the counting sensors and records that the user has completed one target leg-swinging exercise.

[0085] Example 3:

[0086] The difference between this embodiment and Embodiment 1 is that, as Figures 2-4 As shown, there are two supports 2, located on either side of the standing area 4. The standard-setting belt support 6 includes two connecting rods 61. One end of each connecting rod 61 is fixedly connected to the support 2, and the free ends of the two connecting rods 61 are fixedly connected to both ends of the leg-swinging standard-setting belt 5. An adjusting shaft 62 is provided at the connection between the connecting rod 61 and the support 2, and the connecting rod 61 rotates around the axis of the adjusting shaft 62. The leg-swinging standard-setting belt 5 is rotatably connected to the standard-setting belt support 6 about its extension direction.

[0087] In this embodiment, the support portion 32 is provided with an upper limb support 33, a grip handle 34, and a guide handle 35. The upper limb support 33 is made of one or more of a rubber pad, fiber pad, sponge pad, flexible plastic pad, or metal sheet. The grip handle 34 is located on the front side of the support portion 32. The guide handle 35 is located at the end of the support portion 32 closest to the user.

[0088] The support platform 3 is also equipped with a mobile terminal bracket 9 for supporting and adjusting the position of the mobile terminal.

[0089] In another implementation, such as Figure 4 As shown, the standard belt bracket 6 is separate from the bracket 2. The standard belt bracket 6 includes a fixing frame 63, which is set on the outside of the bracket 2. The bottom of the fixing frame 63 is fixed to the ground or the base 1, and the top has two spaced-apart ends. The two ends of the leg swing standard belt 5 are fixedly connected to the two ends of the fixing frame 63.

[0090] Example 4:

[0091] The difference between this embodiment and Embodiment 1 is that the base 1 includes a base plate 1a, the support 2 includes a vertical support 2a, the support platform 3 includes a support plate 3a, and the standing area 4 includes a single-leg standing area 4a; in one embodiment, such as Figures 5-11 As shown, the base 1 is a base plate 1a, the bracket 2 is a vertical bracket 2a, and the support platform 3 is a support plate 3a. The support plate 3a includes a U-shaped opening 31a. One end of the vertical bracket 2a is connected to the middle of the base plate 1a. The base plates 1a located on both sides of the vertical bracket 2a are configured as the single-leg standing area 4a. The other end of the vertical bracket 2a is fixedly connected to the bottom of the support plate 3a. The support part 32 of the support plate 3a is correspondingly configured with an upper limb support area 5a. The upper limb support area 5a is set on the same side as the single-leg standing area 4a.

[0092] The standard-compliant belt support 6 includes a fixing frame 63, which is located on the outside of the vertical support 2a. The bottom of the fixing frame 63 is fixed to the ground and the base plate 1a. The fixing frame 63 is connected to the connecting rod 61 via a locking knob 64. The connecting rod 61 has two spaced-apart ends at its top, and the two ends of the leg-swinging standard-compliant belt 5 are correspondingly fixedly connected to the two ends of the connecting rod 61. The connection between the leg-swinging standard-compliant belt 5 and the connecting rod 61 is provided with a standard-compliant belt locking knob 65 and a standard-compliant belt clamp 66, which are used to adjust the belt surface direction and length of the leg-swinging standard-compliant belt 5.

[0093] In this embodiment, the support plate 3a and the base plate 1a are arranged parallel and spaced apart. The vertical bracket 2a is connected to one side of the support plate 3a. The support plate 3a includes a U-shaped opening 31a, and the upper limb support area 5a is located on both sides of the U-shaped opening 31a. The U-shaped opening 31a on the support plate 3a can accommodate the user's torso. By placing the upper limb support area 5a on both sides of the U-shaped opening, the user's arms can be supported on both sides of the limbs, reducing the load on the legs for body weight. This ensures that the user maintains the correct upright leg-swinging posture when swinging their legs, thus improving the therapeutic effect of leg-swinging therapy.

[0094] In a preferred embodiment, a leg partition 7a is provided on the base plate 1a, and the single-leg standing area 4a is located on both sides of the leg partition 7a. The leg partition 7a is positioned below the U-shaped opening 31a. The height of the leg partition 7a can be any distance from the user's crotch to their feet, allowing the user to stand above the leg partition with both legs positioned on either side of it. The leg partition 7a further enhances the separation of the left and right legs, and also guides the user to swing their legs along the leg partition 7a. It guides and corrects the user's leg swing along the walking direction, preventing improper lateral or diagonal leg swings, and further reducing the probability of kicking the central upright support 2a during leg swings, making the leg swing smooth, unobstructed, and sustainable.

[0095] In a preferred embodiment, a flip-up tabletop 32a is provided on the support plate 3a. The flip-up tabletop 32a includes a tabletop body 321a and a flip-up plate 322a. The tabletop body 321a is mounted on the other side of the support plate 3a, and the flip-up plate 322a is rotatably connected to the tabletop body 321a, so as to have a first working position that is in contact with the tabletop body 321a and a second working position that covers the U-shaped opening 31a. Exemplarily, in this embodiment, a flip-up tabletop 32a composed of a tabletop body 321a and a flip-up plate 322a hinged to each other is provided on the support plate 3a. When the user needs to perform leg-swinging training, the flip-up plate 322a can be flipped up, changing from the second working position to the first working position, exposing the U-shaped opening 31a, allowing the user to stand and perform leg-swinging training in the U-shaped opening 31a. In another operating condition, by flipping the rotating plate 322a back to the second working position, the U-shaped opening 31a is covered and concealed by the rotating plate 322a. The rotating plate 322a then aligns with the tabletop body 321a to form a rotating tabletop 32a with a complete flat surface. At this time, the leg-swinging fitness machine suitable for both home and hospital use can be converted into a desktop mode. Items can be placed on the upper surface of the rotating tabletop 32a, or it can be used as a small table, thus achieving functional switching and improving its practicality in various scenarios such as home, hospital, office, and long-distance high-speed rail travel.

[0096] In another preferred embodiment, a plurality of transverse load-bearing beams 312a protrude from one side of the support plate 3a. Exemplarily, in this embodiment, two transverse load-bearing beams 312a are spaced apart on the bottom surface of the support plate 3a, which is used to strengthen the mechanical strength under the tabletop 321a and ensure the load-bearing stability when the tabletop 321a supports a user's arm or objects. Further, two elbow extension load-bearing beams 313a protrude from one side of the support plate 3a. These two elbow extension load-bearing beams 313a are symmetrically arranged on both sides of the U-shaped opening 311a, and vertically pass through the plurality of transverse load-bearing beams 312a. The elbow extension load-bearing beams 313a span across the tabletop 321a and below the flip plate 322a located in the second working position, primarily serving to reinforce the mechanical strength under the support plate 3a on both sides of the U-shaped opening 31a. Meanwhile, the two elbow-extended load-bearing beams 313a and the two transverse load-bearing beams 312a are arranged perpendicularly to form a load-bearing network, which further improves the overall load-bearing stability.

[0097] As another preferred implementation, such as Figure 10 and Figure 11 The vertical support 2a includes a telescopic adjustment device for vertical telescopic adjustment. The working end of the telescopic adjustment device is fixedly connected to the bottom of the support plate. The telescopic adjustment device includes a lower support body 21a and a sliding column 22a. The bottom of the lower support body 21a is connected to the base plate 1a, and the top of the lower support body 21a is provided with a telescopic groove 211a. One end of the sliding column 22a is perpendicularly connected to one side surface of the support plate 3a, and the other end of the sliding column 22a is slidably inserted into the telescopic groove 211a. Multiple first height positioning holes 221a are arranged at intervals along the extension direction on the sliding column 22a. The lower support body 21a is provided with second height positioning holes 212a that match the first height positioning holes 221a. Positioning pins pass through the first height positioning holes 221a and the second height positioning holes 212a to fix the sliding column to the lower support body. This method is convenient for adjustment, simple in structure, and easy to process and produce. In this embodiment, by adjusting the insertion depth of the sliding column 22a in the telescopic groove 211a, the sliding column 22a can be extended or retracted vertically relative to the lower support body 21a, thereby adjusting the height of the support plate 3a from the ground to accommodate users of different heights and further improve overall adaptability. Simultaneously, by aligning the first height positioning hole 221a on the sliding column 22a with the second height positioning hole 212a on the lower support body 21a, the extension height can be confirmed, and it can be fixed by positioning pins or insertion bolts. The structure is simple and easy to install.

[0098] Optionally, the lower support body 21a includes two side support plates 213a and multiple edge sealing plates 214a. The two side support plates 213a are arranged in parallel and spaced apart, and the multiple edge sealing plates 214a are disposed between the two side support plates 213a and are spaced apart along the horizontal edges of the two side support plates 213a in a direction perpendicular to the base plate 1a, so as to form a telescopic groove 211a between the two side support plates 213a. Exemplarily, the lower support body 21a uses two spaced-apart side support plates 213a to form a flattened support body, and multiple edge sealing plates 214a are provided on both sides of the slit formed by the two side support plates 213a for connection and support, and a telescopic groove 211a structure is defined inside. While ensuring the telescopic cooperation guidance with the sliding column 22a, the lower support body 21a is modularized and lightweight, further improving its practicality.

[0099] Optionally, a reinforcing corner block 215a is provided on the side of the two side support plates 213a that are far apart from each other, and the reinforcing corner block 215a is connected to the base plate 1a. Exemplarily, in this embodiment, by providing a reinforcing corner block 215a structure on the side of the two side support plates 213a that are far apart from each other, the reinforcing corner block 215a can act as a reinforcing rib to strengthen the connection stability between the base plate 1a and the side support plate 213a, further improving the stability of the overall structure.

[0100] In this embodiment, a foot pedal box 8a is provided on the base plate 1a, located below the support plate 3a and on one side of the vertical bracket 2a. The foot pedal box 8a can be designed as a training device with automatic counting function specifically for leg swinging, or it can be a common block structure with a certain mechanical strength (or other shapes that provide support). When the user needs to perform leg swinging training, they can step on the foot pedal box 8a located on one side of the vertical bracket 2a, that is, in the standing area. At the same time, both arms can be supported by the forearms or forearms and supported on the support plate 3a, ensuring that the user can maintain a stable and vertical standing posture with the help of force. At this time, the other affected leg is suspended in the air, and the user can swing the affected leg for rehabilitation training with their own force or with the help of other auxiliary devices.

[0101] In this embodiment, a guide rail 9a is provided on the base plate 1a, with both ends of the guide rail 9a located on both sides of the vertical bracket 2a. The foot pedal box 8a is slidably mounted on the guide rail 9a. For example, in this embodiment, the purpose of providing the foot pedal box 8a is to ensure that the affected leg on the other side can be more easily suspended when the user is standing on one leg, facilitating swinging. By providing the guide rail 9a, the user can adjust the relative position of the foot pedal box 8a along the direction of the guide rail 9a before standing on it, thereby ensuring that it moves to a comfortable stepping position to accommodate users of different body types and different foot spacing. Simultaneously, with both ends of the guide rail 9a located on both sides of the vertical bracket 2a, adjusting the position of the foot pedal box 8a relative to the vertical bracket 2a allows for adjustment of the position of the user's left and right feet, eliminating the need for two separate foot pedal boxes 8a for each user's left and right feet, effectively improving the adaptability of the device for various scenarios.

[0102] As an optional implementation, the bottom of the vertical support 2a is provided with an adjustment hole 23a that matches the foot pedal box 8a, and the guide rail 12 passes through the adjustment hole 23a. Exemplarily, in this embodiment, the guide rail 9a is further configured to pass through the adjustment hole 23a at the bottom of the vertical support 2a, so that the foot pedal box 8a is positioned directly below the U-shaped opening 311a, corresponding to the user's standing position. Simultaneously, when adjusting the relative position of the foot pedal box 11a and the vertical support 2a, it can pass directly below the vertical support 2a, eliminating the need for disassembly and replacement when changing the left or right foot pedal position, further improving the adaptability of the device for various scenarios.

[0103] Example 5:

[0104] The difference between this embodiment and Embodiment 1 is that the base 1 includes a base plate 1b, the bracket 2 includes a side plate 2b, and the support platform 3 includes a lifting platform 3b; in one embodiment, such as Figures 12-21 As shown, the base 1 is a base plate 1b, the bracket 2 is a side plate 2b, and the support platform 3 is a lifting platform 3b.

[0105] A lifting platform 3b for elbow support and height adjustment is mounted on the upper surface of the side panel 2b. A middle partition 4b arranged front to back is located in the center of the base plate 1b, and a seat support device 12b for sitting or leaning is located on the upper end of the middle partition 4b. A lifting pedal assembly 8b is provided on the base plate 1b and is located on the standing area 4. The lifting pedal assembly 8b is located below the receiving opening 31. During the user's leg swinging process, the relative position of the vertical projection of the bracket 2 and the lifting pedal assembly 8b remains unchanged. The lifting pedal assembly 8b includes pedal one and pedal two, which are arranged in pairs. When pedal one or pedal two is in the raised stop position, it is a load-bearing pedal; when pedal two or pedal one is in the lowered stop position, it is an unloaded pedal. The lifting power device drives pedal one and pedal two to alternately move between the raised stop position and the lowered stop position. That is, after the lifting power device drives pedal one and pedal two to the raised stop position and the lowered stop position, pedal one and pedal two are in a paused state, which is convenient for users to perform leg swing training in this paused state. After swinging to the target number of times, pedal one and pedal two are switched, and the lifting power device drives pedal one and pedal two to the lowered stop position and the raised stop position, and then to the paused state, which is convenient for users to switch legs for leg swing training. When swinging the leg, the user stands on the load-bearing pedal in the raised position and swings their leg above the unloaded pedal in the lowered position. When the swinging leg passes above the front and / or rear of the standing area 4 and touches the leg-swinging target strip 5, the target strip 5 sends a feedback signal indicating that the user has completed a leg-swinging motion that meets the standard amplitude. At this time, the counting sensor transmits the collected signal to the control component. After a certain target is achieved, the control component drives the two pedals to open as the corresponding left and right lifting pedals descend and close as the corresponding left and right lifting pedals rise, respectively.

[0106] like Figure 19 As shown, the lifting platform 3b includes a fence panel 3b-1 with an inverted U-shaped cross-section. An inverted U-shaped support platform 3b-2 for supporting the elbow is fixed on the upper surface of the fence panel 3b-1. A cantilever support 3b-6 connected to the underarm support device 3b-8 is fixed on the lower surface of the inverted U-shaped support platform 3b-2 and inside the fence panel 3b-1. A telescopic column 3b-3 is fixed on one side of the cantilever support 3b-6. The telescopic end 3b-32 of the telescopic column 3b-3 is fixedly connected to the cantilever support 3b-6. The telescopic base end 3b-31 of the telescopic column 3b-3 is fixedly connected to the side plate 2b.

[0107] like Figure 15 , Figure 16As shown, below the U-shaped opening of the inverted U-shaped support platform 3b-2, the upper end of the seat support device 5b is provided with a seat support area to support the user's buttocks. The seat support device 5b includes a U-shaped seat switching device 5b-1. The seat switching device 5b-1 is provided with a seat support 5b-4 that can be flipped up and down and moved back and forth relative to each other. When the seat support 5b-4 is flipped up, the seat support 5b-4 is in the buttocks leaning state. When the seat support 5b-4 is laid flat, the seat support 5b-4 is in the buttocks sitting state. The seat switching device 5b-1 is connected to the seat support lifting device 5b-2, which is arranged on the middle partition 4b and can be raised and lowered, through the lifting tube 5b-13 provided at its lower end. The rear end of the seat support lifting device 5b-2 is provided with a locking valve 5b-3 for locking or releasing the lifting tube 5b-13.

[0108] Preferably, the seat-leaning switching device 5b-1 includes a toothed horizontal limiting plate 5b-14 at the upper part of the Γ-shape and a lifting tube 5b-13 at the lower part of the Γ-shape. The toothed horizontal limiting plate 5b-14 has sliding grooves 5b-12 arranged front and rear on both its left and right sides. A damping slider shaft 5b-11 matching the sliding groove 5b-12 is provided within the sliding groove 5b-12. Figure 16 As shown, the seat support 5b-4 includes a connecting plate 5b-41 connected to the damping slider shaft 5b-11 via a pivot mounting hole 5b-42. The left and right connecting plates 5b-41 form a U-shaped fork 5b-43, the width of which matches the width of the toothed horizontal limiting plate 5b-14. A rack 5b-44 is provided at the bottom of the U-shaped fork 5b-43, which meshes with any tooth of the toothed horizontal limiting plate 5b-14 to prevent the rack 5b-44 from sliding back and forth when the seat support 5b-4 is upright. Additionally, the fore-and-aft position of the seat support 5b-4 (in the buttocks-leaning position) can be adjusted to accommodate different body types. The seat support lifting device 5b-2 includes a seat support lifting column 5b-21 mounted on the intermediate partition 4b. The seat support lifting column 5b-21 can be automatically controlled by an electric lever or manually adjusted for high pressure.

[0109] like Figure 17 As shown, the damping slider shaft 5b-11 includes a slider 5b-111 that slides in a groove 5b-12. The slider 5b-111 has a damping shaft 5b-112 that can dampen rotation on its outer side. A seat support mounting block 5b-113 is fixedly provided on the outer periphery of the damping shaft 5b-112. The seat support mounting block 5b-113 is fixed in a fit with the shaft mounting hole 5b-42.

[0110] The damping pivot 5b-112 and the slider 5b-111 can rotate with damping, allowing for arbitrary stopping. The damping pivot 5b-112 is fixed relative to the support mounting block 5b-113, which in turn is fixed to the support 5b-4 through the pivot mounting hole 5b-42. Therefore, the support 5b-4 can rotate and stop arbitrarily relative to the toothed horizontal limit plate 5b-14. The special feature of this damping slider pivot 5b-11 is that it combines a straight damping hinge with the slider 5b-111, allowing for both rotation and sliding, making the adjustment of the support 5b-4 more flexible.

[0111] The seat support device 5b of this invention serves as an auxiliary support for the buttocks and can flexibly switch between a buttocks-leaning state and a buttocks-sitting state or work simultaneously. It can not only reduce the force on the standing leg when swinging the leg while standing on one leg, but also allow the user to swing the leg while sitting or take a short rest during exercise intervals. At the same time, the seat support device 5b can move back and forth and up and down to adapt to patients of different heights and body types.

[0112] Preferably, the underarm support device 3b-8 adopts an electric rod automatic control lifting method or a manual pressure adjustment tightening method.

[0113] like Figure 18 As shown, the axillary support device 3b-8 adopts an automatic lifting and lowering method controlled by an electric rod. It includes a vertically arranged electric rod 3b-81, and a control component electrically connected to the electric rod 3b-81, controlling the movement of the electric rod 3b-81 according to the control instructions of the computer program. The electric rod 3b-81 is fixedly connected to the side of the lifting platform 3b. A telescopic rod 3b-82 is provided inside the electric rod 3b-81. Arc-shaped axillary support plates 3b-83 are respectively provided on the left and right sides of the telescopic rod 3b-82. The axillary support plates 3b-83 are connected to the telescopic rod 3b-82 through an axillary support plate pivot 3b-84 set at the upper end of the telescopic rod 3b-82, so that the axillary support plates 3b-83 can rotate inward and outward around the axillary support plate pivot 3b-84 to adapt to patients of different body types.

[0114] The axillary support device 3b-8 of the present invention serves as an auxiliary axillary support. When the patient leans forward, the arc-shaped axillary support plate 3b-83 provided on the left and right sides of the telescopic rod 3b-82 supports the patient's armpit, reducing the force on the standing leg when standing on one leg and swinging the leg. At the same time, the arc-shaped axillary support plate 3b-83 can move up and down and rotate inward and outward to adapt to patients of different heights and body types.

[0115] like Figure 19 and 20As shown, the lifting platform 3b includes a fence panel 3b-1 with an inverted U-shaped cross-section. An inverted U-shaped support platform 3b-2 for supporting the elbow is fixed on the upper surface of the fence panel 3b-1. A cantilever support 3b-6 connected to the underarm support device 3b-8 is fixed on the lower surface of the inverted U-shaped support platform 3b-2 and inside the fence panel 3b-1. A telescopic column 3b-3 is fixed on one side of the cantilever support 3b-6. The telescopic end 3b-32 of the telescopic column 3b-3 is fixedly connected to the cantilever support 3b-6. The telescopic base end 3b-31 of the telescopic column 3b-3 is fixedly connected to the side plate 2b.

[0116] Specifically, the cantilever support 3b-6 includes a lifting platform connecting surface 3b-62 that is fixedly connected to the inverted U-shaped support platform 3b-2. The side end of the lifting platform connecting surface 3b-62 is provided with a telescopic column connecting port 3b-63 that is connected to the telescopic column telescopic end 3b-32. The side of the lifting platform connecting surface 3b-62 near the patient is provided with an axillary support connecting end 3b-61 that is connected to the axillary support device 3b-8.

[0117] The side panel 2b includes a side panel shell 2b-1 and a side panel cover 2b-2. The side panel shell 2b-1 includes vertically arranged reinforcing ribs 2b-11 with a U-shaped cross-section. A telescopic column base end 3b-31 is embedded in the U-shaped groove of the reinforcing rib 2b-11. The bottom end of the reinforcing rib 2b-11 extends inward to a base plate fixing connection end 2b-12 that is embedded in the base plate 1b. A telescopic column reduction motor 3b-33 is sleeved inside the base plate fixing connection end 2b-12. The height of the inverted U-shaped support platform 3b-2 can be adjusted by extending and retracting the telescopic column 3b-3 to accommodate patients of different heights.

[0118] Preferably, a control panel 3b-4 is provided on the inverted U-shaped support platform 3b-2. The control panel 3b-4 is electrically connected to the lifting transmission mechanism of the two pedals of the lifting pedal assembly 8b, and controls the lifting transmission mechanism to rise / fall. In this embodiment, the control component, i.e., the control panel 3b-4, includes a control device, a communication module, a power module, etc., and controls the lifting transmission mechanism in the lifting pedal assembly 8b to move up and down through a computer program, thereby realizing the alternating position of pedal one and pedal two.

[0119] The inverted U-shaped support platform 3b-2 has symmetrically arranged elbow support devices 3b-5 on both the left and right sides for assisting elbow support. Each elbow support device 3b-5 includes an elbow support link 3b-51 with one end dampedly hinged to the inverted U-shaped support platform 3b-2. By adjusting the rotation angle of the elbow support link 3b-51 on the inverted U-shaped support platform 3b-2, the distance between the left and right elbow support links 3b-51 can be changed to accommodate patients of different body types. The other end of the elbow support link 3b-51 is dampedly hinged to an elbow support 3b-52. By adjusting the rotation angle of the elbow support 3b-52 on the elbow support link 3b-51, the support angle between the patient's arm and the elbow support 3b-52 can be freely adjusted.

[0120] Specifically, the elbow support link 3b-51 rotates at an angle of 0 to 90° on the inverted U-shaped support platform 3b-2. When the elbow support link 6-51 rotates to the vertical direction (i.e., 0°), the distance between the left and right elbow support links 6-51 is the widest, suitable for people with a large build. When the elbow support link 3b-51 rotates to the horizontal direction (i.e., 90°), the distance between the left and right elbow support links 6-51 is the narrowest, suitable for people with a petite build.

[0121] The elbow support device 3b-5 of this invention serves as an auxiliary elbow support. By adjusting the rotation angle of the elbow support on the elbow support link 3b-51, the support angle between the patient's arm and the elbow support can be freely adjusted, reducing the force borne by the standing leg when performing leg-swinging movements while standing on one leg. At the same time, by adjusting the rotation angle of the elbow support link 3b-51 on the support platform, the distance between the left and right elbow support links can be changed to adapt to patients of different body types. By adjusting the height of the lifting platform, it is convenient for patients of different heights to support their elbows.

[0122] Preferably, the front of the inverted U-shaped support platform 3b-2 is provided with left and right grip supports 3b-10 for hand gripping, which are used to provide the patient with stable balance when swinging their legs significantly. The inverted U-shaped support platform 3b-2 is also provided with a monitor bracket 3b-7 for supporting and adjusting the position of the monitor.

[0123] The inverted U-shaped support platform 3b-2 is also equipped with an inverted U-shaped front railing grip support 3b-11 for gripping and holding on. This adds an optional gripping method to the left and right grip supports 3b-10, similar to holding onto a railing. The lifting platform 3b has left and right grip supports 3-10 on both sides of the platform. Unlike the previous two grip supports, the left and right grip supports 3b-10 are held by the hand on the handle, using the strength of the arm for support. The front railing grip support 3b-11 can be used to support the body weight with the elbow, while also serving as an auxiliary support to further balance and stabilize the user's body.

[0124] The monitor stand 3b-7 is used to adjust the position of the mobile terminal. The monitor and the mobile terminal are connected to the KOAPT therapy rehabilitation device with automatic leg-changing function of this invention by downloading an APP. On the one hand, data can be displayed in real time through the mobile terminal, and on the other hand, users can switch the mobile terminal interface independently for entertainment, office work and other activities.

[0125] Preferably, the height of the middle partition 4b is 0.4 to 0.8 m. If the middle partition 4b is too high, it will be difficult for the patient to step over with one leg. If the middle partition 4b is too low, it will cause the seat support lifting column 5b-21 to break due to excessive lifting range.

[0126] Specifically, the height of the intermediate partition 4b is 0.6-0.8m, preferably 0.5m.

[0127] like Figure 21 As shown, when a user uses this invention to swing their legs, they can support their elbows on the elbow support device 3b-5 while resting their buttocks on the seat support 5b-4; alternatively, they can support their elbows on the elbow support device 3b-5 while resting their armpits on the armpit support plate 3b-93; or they can rest their buttocks on the seat support 5b-4, freeing their hands; or they can even sit directly on the seat support 5b-4 to swing their legs. In this way, the patient can completely free their hands while swinging their legs and use the lifting platform for reading, writing, computer work, etc., so as to achieve both exercise rehabilitation and work / study without any disruption.
