Description

Technical Field

[0001] This utility model relates to the field of therapeutic rehabilitation exercise technology, and in particular to a foot dorsiflexion training device, training components and training equipment for KOA-PT exercise. Background Technology

[0002] KOA-PT therapy is an effective treatment for knee pain. KOA-PT requires patients to continuously complete KOA-PT exercises according to their KL level and the corresponding graded treatment plan. The principle of KOA-PT exercises is to use hip joint swinging to 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. This secondaryly causes a phased, alternating increase and decrease in intra-articular pressure, thereby promoting the secretion and absorption of synovial fluid within the joint cavity. This effectively removes various inflammatory factors and pain factors from the joint cavity. Furthermore, the increased circulation of synovial fluid promotes positive repair of articular cartilage. Overall, it alleviates knee pain symptoms and provides a valuable pathophysiological basis for the repair of damaged articular cartilage.

[0003] In this research, Mr. Song Jiuhong, the proposer of the KOA-PT therapy, discovered a direct positive correlation between the active strengthening of the knee muscles during leg swinging and the therapeutic effect on KOA symptoms. The strength of the calf flexor and extensor muscles around the ankle joint is typically achieved through ankle dorsiflexion and plantarflexion movements, commonly known as "ankle pump" exercises. During "ankle pump" exercises, the tibialis anterior and gastrocnemius muscles exhibit synergistic and antagonistic relationships. When the tibialis anterior contracts to dorsiflex the ankle, the gastrocnemius relaxes synchronously; conversely, when the gastrocnemius contracts to plantarflex the ankle, the tibialis anterior relaxes synchronously. Knee joint stability is achieved through the coordinated effort of the thigh and calf muscles. "Ankle pump" exercises can strengthen the tibialis anterior and gastrocnemius muscles, working in conjunction with the thigh muscles to increase knee joint stability, thus better relieving or preventing degenerative knee diseases. Simultaneously, "ankle pump" exercises can also enhance the proprioceptive sensitivity and adaptability of the affected limb.

[0004] Further research revealed that in the traditional KOA-PT therapy leg-swinging exercise, since the leg does not have to bear the exerciser's own weight, the calf muscles can complete the predetermined leg-swinging exercise goal even if they are in a relatively relaxed state throughout the exercise. However, the calf muscles in a relaxed state cannot better coordinate with the thigh muscles to achieve the contraction and relaxation movements around the synovial bursa in the knee joint cavity. As a result, the overall improvement of the strength of the flexor and extensor muscles of the leg and the efficiency of proprioceptive coordination are not high.

[0005] KOA patients often experience decreased strength and muscle atrophy in their tibialis anterior and gastrocnemius muscles due to long-term knee pain and lack of movement. As a result, when moving forward or backward, their toes and heels cannot lift off in time, leading to foot drop and ankle pump incoordination. At the same time, this decrease in muscle strength can also cause a decline in proprioceptive coordination in the lower limbs. All of these factors can cause KOA patients to lose their balance and fall even when walking on flat ground due to dragging their toes and heels, which can result in serious soft tissue contusions, joint and tendon sprains, fractures, and other physical injuries.

[0006] Furthermore, when using treatment and rehabilitation equipment for KOA-PT exercises, patients often swing their legs freely, or the legs and feet are simply supported and fixed to assist in the swinging of the lower limbs. During the leg swinging process, the patient's feet often cannot complete the dorsiflexion and plantarflexion required by KOA-PT exercises in a very standard manner, which fails to effectively train the strength of the tibialis anterior and gastrocnemius muscles and cannot provide sufficient stimulation to the muscles around the knee, resulting in poor training and rehabilitation effects. Utility Model Content

[0007] To address the shortcomings of existing technologies, this application provides a foot dorsiflexion training device, training components, and training equipment for KOA-PT exercises, in order to improve the effectiveness of tibialis anterior and gastrocnemius muscle strength training during KOA-PT exercises and ensure the effectiveness of rehabilitation treatment.

[0008] To achieve the above objectives, this application presents a foot dorsiflexion and plantar flexion training device for KOA-PT exercise, characterized in that it includes: a foot support and a counterweight block. The foot support includes a support plate and a foot instep fixing cover. The foot instep fixing cover is disposed around the top surface of the support plate and defines a foot support space with the support plate. At least one of the support plate and the foot instep fixing cover is provided with a counterweight mounting position for placing the counterweight block, and the counterweight mounting position is located at the corresponding position of the toe.

[0009] For patients with knee periarthritis, a more effective KOA-PT exercise therapy should be adopted, which breaks down a round-trip KOA-PT movement into five consecutive movement units: 1. Kick forward with the lower limb while dorsiflexing the foot (pointing the toes); 2. During the backward movement of the lower limb, plantarflexion of the foot (extension of the foot) and gradual flexion of the knee joint; 3. The lower limb swings behind the body, the knee joint flexes, and the heel bounces (i.e., the foot bounces back); 4. The lower limb swings forward and upward from back, with the foot gradually changing from plantarflexion (extension of the foot) to dorsiflexion (pointing the toes); 5. The lower limb moves forward and upward to the front of the body, the knee joint straightens, and the ankle joint dorsiflexes (points the toes). In summary, the completion of one cycle of the five decomposed movement units of the forward and backward swing of the lower limb is considered a standard KOA-PT cycle.

[0010] When performing KOA-PT exercises, users wear a foot dorsiflexion and plantarflexion training device to repeatedly perform dorsiflexion and plantarflexion movements. During dorsiflexion, the user flexes their foot and raises their toes. A weight placed at the toes applies pressure to the toes, and the user uses their tibialis anterior muscle to drive the ankle to complete the dorsiflexion movement, thus training the tibialis anterior muscle. In medicine, the toes are defined as the portion of the foot closer to the big toe than the portion of the toe that is closer to the big toe and the portion of the foot closer to the ankle. The midpoint of the vertical line is the dorsum of the foot.

[0011] When users perform leg-swinging exercises using a foot dorsiflexion and plantar flexion training device, the position of the weights directly affects the training effect. When a user performs a weighted ankle flexion and extension movement, they work upwards by flexing and extending their foot around the ankle. When the weights are near the instep or arch, the lever arm of the force is approximately the distance from the ankle to the instep or arch (let's call it La). When the weights are near the toes, the lever arm is approximately the distance from the ankle to the toes (let's call it Lb). Clearly, Lb > La. For the same force F applied by the user, the torque of the latter is greater than the torque of the former, i.e., F... Lb>F La.

[0012] Therefore, it is evident that placing the weights at the toes can effectively improve training efficiency. This is especially true for elderly users and those with foot drop, whose lower limb muscle strength is insufficient to transmit adequate force to the ankles. Weights positioned at the toes can enhance the user's performance, boost their confidence, and encourage them to continue exercising.

[0013] The weights are positioned at the toes. When performing KOA-PT exercises, the user uses their calf muscles to swing their feet while simultaneously tensing and raising their toes to overcome the pressure of the weights. This trains the proprioceptors and helps prevent foot drop.

[0014] Furthermore, the counterweight is detachably connected to the counterweight mounting position.

[0015] Furthermore, the counterweight can be configured in various ways, each with a different weight. The position and weight of the counterweight are adjustable to suit the personalized needs of different users.

[0016] Furthermore, the counterweight mounting position is located on the outer surface of the front end of the tray, corresponding to below the user's toes.

[0017] Furthermore, the counterweight mounting position is a first mounting groove, which is set along the length of the tray and its length does not exceed 40% of the length of the tray. Setting the counterweight within this length range can effectively utilize the user's muscle strength and facilitate the user's training of proprioceptors.

[0018] Furthermore, the counterweight mounting position is a second mounting groove located on the outer surface of the foot fixing cover near the front end of the support plate.

[0019] If the weight is installed on the instep of the user, it will be more difficult for the user to perform the dorsum of the foot movement. At the same time, the weight will rub against the skin of the instep, creating a foreign body sensation. Therefore, if the weight is placed on the upper surface of the user's toes, the dorsum of the foot, plantar muscles and proprioceptors will be trained more effectively.

[0020] Furthermore, the counterweight is provided with an installation arc surface that matches the outer surface of the foot fixing cover.

[0021] Furthermore, the counterweight block and the counterweight mounting position are attached by Velcro, making it easy to clean and replace.

[0022] Furthermore, the outer surface of the counterweight is covered with an anti-slip cloth cover, and the Velcro is set on the anti-slip cloth cover. The anti-slip cloth cover can also be marked to remind the user of the weight and type of the counterweight it is supporting, which further improves the practicality of the foot dorsiflexion training device.

[0023] Furthermore, the first mounting groove is a through groove communicating with the bottom surface of the tray, which facilitates the installation and removal of the counterweight.

[0024] Furthermore, the counterweight block and the counterweight mounting position are magnetically attached.

[0025] Furthermore, the side of the counterweight smoothly transitions with the side profile of the tray, making the overall appearance of the device harmonious and aesthetically pleasing.

[0026] Furthermore, it also includes a foot counterweight position for placing counterweight blocks. The foot counterweight position is a third mounting groove located on the side end face of the support plate, and the counterweight blocks are inserted into the third mounting groove. Inserting counterweight blocks into the third mounting groove can increase the weight of the bottom of the shoe support, which is suitable for foot weight-bearing training.

[0027] Furthermore, the counterweight block and the third mounting slot are fixed together by a limiting device.

[0028] Furthermore, the counterweight and the third mounting groove are magnetically attached to each other.

[0029] Furthermore, the third mounting slot is elongated and closed at one end.

[0030] Furthermore, multiple third mounting slots are provided and are evenly spaced along the length of the tray.

[0031] Furthermore, it also includes a heel counterweight position for placing counterweight blocks. The heel counterweight position is a fourth mounting groove located on the outer surface of the rear end of the support plate, and the counterweight blocks are inserted into the fourth mounting groove. Inserting counterweight blocks into the fourth mounting groove can increase the weight of the heel of the shoe, which is suitable for back flexion training in KOA-PT movements.

[0032] In the third movement of KOA-PT, when the user's heel is in a buttock-bumping motion (meaning the foot bounces back), the tibialis anterior, gastrocnemius, and hamstring muscles work simultaneously to pull the heel towards the buttocks through the ankle, while the instep is pointed, and the dorsalis and plantar muscles are stretched. Weighted ankle flexion training is suitable for users with strong leg muscles, and the detachable weights allow for personalized needs at different training stages.

[0033] Furthermore, the foot support cover has an opening. It also includes a heel support strap, the opening of which faces the rear end of the support plate, and the two ends of the heel support strap are detachably connected to the two ends of the opening.

[0034] This utility model also proposes a training component for KOA-PT exercise. The component includes a base plate and the aforementioned foot dorsiflexion training device for KOA-PT exercise. The base plate includes a base, on which a lifting platform pedal assembly is provided. The lifting platform pedal assembly includes lifting pedals and a lifting power device. The lifting power device drives the lifting pedals to perform lifting and lowering movements. The electric base plate assembly is provided with at least two lifting pedals, including pedal one and pedal two. Pedal one and pedal two are arranged in pairs along the horizontal direction. The lifting power device drives pedal one and pedal two to alternately be in the raised stop position and the lower stop position. 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 lower stop position, it is an unloaded pedal.

[0035] This utility model also proposes a training device for KOA-PT exercise, including a training support frame for KOA-PT foot dorsiflexion training. The training support frame includes a base, a support frame, and a leg swing 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 swing target belt are installed on the target belt support. The leg swing target belt is horizontally arranged above the front side and / or above the rear side of the standing area on the patient's leg swing path. When the patient swings their leg and touches the leg swing target belt, the leg swing target belt provides feedback of the target achievement signal.

[0036] This invention presents a foot dorsiflexion and plantar flexion training device, training components, and training equipment for KOA-PT exercises to help users achieve KOA-PT training. When users need to perform leg swing training, they can insert their feet into the foot instep fixing cover through the inlet and step on the support plate. The foot instep fixing cover adopts an arc-shaped cover structure designed to mimic the shape of the human foot, forming a "shoe-like" structure together with the support plate, utilizing the foot support space formed by its internal enclosure to surround and support the patient's foot. Furthermore, after the patient has completed putting on the foot, according to actual needs, counterweights can be added to the corresponding points on the toe of the foot instep fixing cover and / or support plate (as well as the instep, heel, and sole) to increase the weight on the corresponding parts. All these increases in lower limb load not only strengthen the tibialis anterior and gastrocnemius muscles during weight-bearing exercises, but also correspondingly enhance the strength of the quadriceps and hamstring muscles. This motivates users to perform foot extension and / or flexion movements more accurately during swinging motions, thereby improving the standard of dorsiflexion training of the foot during KOA-PT exercises and ensuring training effectiveness.

Detailed Implementation

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 As shown, this embodiment provides a foot dorsiflexion training device, including a foot support 1 and a counterweight 2.

[0041] The foot support 1 includes a support plate 11 and a foot fixing cover 12. The foot fixing cover 12 is disposed around the top surface of the support plate 11 and defines a foot support space a with the support plate 11. The foot fixing cover 12 has an opening 121. At least one of the support plate 11 and the foot fixing cover 12 is provided with a counterweight mounting position b for placing a counterweight block 2, and the counterweight mounting position b is located at the corresponding position of the toe.

[0042] Example 1: In this embodiment of the invention, the foot dorsiflexion training device works in conjunction with a corresponding leg swing frame. The user wears the foot dorsiflexion training device and stands on the leg swing frame to perform KOA-PT exercises. When the user needs to perform leg swing training, they can insert their foot into the foot instep fixing cover 12 through the insertion port 121 and step onto the support plate 11. The foot instep fixing cover 12 adopts an arc-shaped cover structure designed to mimic the shape of the human foot, forming a "shoe-like" structure together with the support plate 11. The foot support space a formed by its internal enclosure surrounds and supports the patient's foot. Furthermore, the counterweight 2 is detachably connected to the counterweight mounting position b. After the patient completes the foot wearing, the counterweight 2 can be added to the foot instep fixing cover 12 and / or the support plate 11 according to actual needs to increase the weight on the toe area. This increases stimulation to the corresponding areas of the foot during leg swinging, encouraging users to perform foot extension and / or flexion movements more accurately, thereby improving the standard of dorsiflexion training during KOA-PT exercises and ensuring training effectiveness.

[0043] Example 2: Optionally, such as Figure 2As shown, there are various types of counterweights 2, each with a different weight. Exemplarily, in this embodiment of the invention, based on the patient's symptom severity and training program duration, different weights of counterweights 2 can be selected and installed at corresponding positions on the foot fixation cover 12 and / or support plate 11 to suit the patient's rehabilitation training, thus improving the adaptability and practicality of the foot dorsiflexion training device.

[0044] like Figure 2 As shown, the counterweight mounting position b is located on the outer surface of the foot fixing cover 12 near the front end of the support plate 11, and the counterweight block 2 is fixed to the counterweight mounting position b by a limiting device.

[0045] Example 3: Optionally, the counterweight mounting position b is located on the outer surface of the front end of the support plate 11, and the counterweight block 2 is fixed to the counterweight mounting position b by Velcro. Exemplarily, in this embodiment of the invention, a strip-shaped Velcro structure is provided on the outer surface of the foot fixation cover 12 near the front end of the support plate 11 as the counterweight mounting position b on the foot fixation cover 12. The patient can attach and install the counterweight block 2 at any position along the extension path of the Velcro according to actual needs. The counterweight block 2 attached to the outer surface of the foot fixation cover 12 focuses on increasing weight and stimulating the patient's forefoot and instep, ensuring that the patient can forcefully extend their foot during leg swinging. Its position is convenient to select, and the Velcro attachment method is easy to adjust, further improving the adaptability and practicality of the foot dorsiflexion training device.

[0046] Optionally, the counterweight 2 is provided with an mounting arc surface 21 that matches the outer surface of the foot fixing cover 12. Further, in this embodiment of the invention, since the foot fixing cover 12 adopts an arc-shaped cover structure designed to mimic the shape of the human foot, the counterweight 2 used for mounting on the foot fixing cover 12 is adaptively designed, with an mounting arc surface 21 provided on it as the contact surface with the outside of the foot fixing cover 12. The Velcro on the other side is provided through this mounting arc surface 21, increasing the contact area between the counterweight 2 and the foot fixing cover 12 and ensuring stable installation.

[0047] Optionally, the outer surface of the counterweight 2 is covered with an anti-slip cloth sleeve 22, and Velcro is attached to the anti-slip cloth sleeve 22. Further, in this embodiment of the invention, the outer surface of the counterweight 2 can be supported by a dedicated anti-slip cloth sleeve 22, with Velcro attached to the anti-slip cloth sleeve 22 to connect it to the foot fixing cover 12, facilitating production. The anti-slip cloth sleeve 22 can also be marked to remind the user of the weight and type of the counterweight 2 it supports, further improving the practicality of the foot dorsiflexion training device.

[0048] Example 4: Optionally, such as Figure 3 As shown, the counterweight mounting position b is a first mounting groove b1 located on the front end face of the tray 11, and the counterweight block 2 is fixed in the first mounting groove b1 by Velcro.

[0049] Optionally, the first mounting groove b1 is provided along the length direction of the tray 11, and its length does not exceed 40% of the length of the tray 11.

[0050] For example, the counterweight mounting position b can also be located below the front end face of the tray 11. Similar to hollowing out the front end of the tray 11 to form a through-groove structure communicating with the bottom surface of the tray 11, this first mounting groove b1 serves as a counterweight mounting position b on the tray 11. The counterweight block 2 can also be wrapped in a cloth sleeve and attached to the first mounting groove b1 using Velcro, thereby increasing the weight on the lower front part of the patient's foot.

[0051] Optionally, the side profile of the counterweight 2 smoothly transitions with the side profile of the support plate 11. Furthermore, in this embodiment of the invention, the external profile of the counterweight 2 installed in the first mounting groove b1 remains consistent with the upper side profile, ensuring structural aesthetics while facilitating alignment and positioning during installation, thus helping the user confirm whether it is correctly installed.

[0052] In another possible implementation, refer to Figure 4 The counterweight mounting position b includes a second mounting groove b2 located on the outer surface of the front end of the support plate 11, which corresponds to the upper surface of the toe. The counterweight block 2 is inserted and engaged with the counterweight mounting position b.

[0053] If the mounting position is set on the instep of the user, the user will have to exert more effort when performing the flexion movement. At the same time, the mounting block 2 will rub against the skin of the instep, creating a foreign body sensation. Therefore, the weight block 2 is set in the second mounting groove b2 on the upper surface of the user's toes, which makes the user's flexion training more effective and can train the instep muscles and plantar muscles at the same time.

[0054] Example 5: Optionally, the counterweight 2 and the counterweight mounting position b are magnetically attached. The counterweight 2 is magnetically attached to a magnetic body installed in the first mounting groove b1, and the counterweight 2 and the magnetic body form a magnetic connector.

[0055] Example 6: Optionally, refer to Figure 5 It also includes a foot counterweight position c for placing the counterweight block 2. The foot counterweight position c is a third mounting groove c1 set on the side end face of the support plate 11, and the counterweight block 2 is inserted into the third mounting groove c1.

[0056] Exemplarily, in another possible implementation, the support plate 11 has a third mounting groove c1 in the form of a countersunk hole on one end face along the extension direction of the patient's foot. By directly inserting a counterweight 2 of the corresponding shape into the third mounting groove c1 from the side, the counterweight below the patient's foot can be increased. This is used to increase the overall weight of the training device, focusing on increasing the weight and stimulating the area below the patient's foot, ensuring that the patient can forcefully hook their foot during the leg swing to ensure the swing stroke.

[0057] Optionally, such as Figure 5 As shown, the third mounting slot c1 is elongated and closed at one end. Further, in this embodiment of the invention, the third mounting slot c1 is elongated, and multiple third mounting slots c1 can be evenly spaced along the length of the support plate 11 to allow for the installation of corresponding counterweights 2 on different parts of the patient's foot; alternatively, counterweights 2 can be simultaneously installed in multiple third mounting slots c1 to achieve a gradient increase in overall weight, adapting to different training cycles and further improving adaptability.

[0058] Example 7: Optionally, a snap-fit ​​limiting device is provided at the bottom of the third mounting slot c1. The snap-fit ​​limiting device is equipped with a spring. When the counterweight 2 is inserted into the third mounting slot c1, the limiting device snaps and fixes the counterweight 2. When it is necessary to remove the counterweight 2, the counterweight 2 is pushed to compress the spring, and the limiting device releases the constraint on the counterweight 2.

[0059] Example 8: Optionally, such as Figure 6 As shown, it also includes a heel counterweight position d for placing the counterweight block 2. The heel counterweight position d is a fourth mounting groove d1 located on the outer surface of the rear end of the support plate 11, and the counterweight block 2 is inserted into the fourth mounting groove d1. The counterweight block 2 is arc-shaped, fits the rear end of the support plate 11, and covers the user's heel. When the user performs the third movement of KOA-PT, the heel is in a buttock-bumping position (meaning the foot bounces back), the tibialis anterior, gastrocnemius, and hamstring muscles work together to pull the heel closer to the buttock through the ankle, while the instep is straightened, and the dorsalis pedis and plantar muscles are stretched. Weighted ankle flexion training is suitable for users with strong leg muscles, and the detachable counterweight blocks expand the user's personalized needs in different training periods.

[0060] Example 9: Optionally, it also includes a heel fixing strap 13, with the insertion port 121 opening towards the rear end of the support plate 11. Both ends of the heel fixing strap 13 are detachably connected to both ends of the insertion port 121. Exemplarily, in this embodiment of the invention, the foot instep support cover 12 can be configured to cover only the front of the patient's foot, similar to a "slipper" structure, while the heel is supported and fitted using the fixing strap 13, whose ends are detachable and adjustable. When the patient's foot is inserted, one end of the fixing strap 13 can be separated from the foot instep support cover 12 for easy wearing. Furthermore, depending on the size of the patient's foot, the heel fixing strap 13 can also be connected via Velcro or other means. By changing the connection position with the foot instep support cover 12, the overall extension length of the heel fixing strap 13 can be adjusted to ensure a tight fit to the patient's heel and maintain support stability.

[0061] The foot dorsiflexion training device proposed in this utility model can customize the weight block settings according to the user's KOA level and personal situation; for example, it can be set only at the toe, simultaneously at the toe and / or the sole and / or the heel, at the toe and the heel, at the toe and the sole, etc., and can be set at different positions according to a certain weight ratio to meet the user's personalized needs and adapt to different training cycles, further improving the adaptability of the device.

[0062] Figure 7 This is a schematic diagram of the structure of a training component for KOA-PT exercise provided in an embodiment of this utility model. Figure 7 As shown, this utility model also proposes a training component for KOA-PT exercise. This component includes a base plate and the foot dorsiflexion training device for KOA-PT exercise described in Examples 1-9. The base plate includes a base e1, on which a lifting platform pedal assembly e2 is mounted. The lifting platform pedal assembly e2 includes lifting pedals and a lifting power device. The lifting power device drives the lifting pedals to move up and down. The electric base plate assembly has at least two lifting pedals, including pedal one e21 and pedal two e22. Pedal one e21 and pedal two e22 are arranged in pairs along the horizontal direction. The lifting power device drives pedal one e21 and pedal two e22 to alternately be in the raised stop position and the lowered stop position. When pedal one e21 or pedal two e22 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.

[0063] The patient wears a foot dorsiflexion and plantarflexion training device and stands on the base plate to perform KOA-PT exercises. While swinging their leg, the patient performs dorsiflexion and plantarflexion movements, allowing for easy leg switching. Two pedals on the base plate intermittently alternate between the raised and lowered positions. When swinging the leg, the patient stands on the weighted pedal in the raised position and swings their leg above the unloaded pedal in the lowered position, achieving voluntary leg-swinging training. After reaching a certain goal, the lifting power device drives the lifting pedals to switch between the raised and lowered positions, allowing the patient to switch legs and continue leg-swinging training.

[0064] Figure 8 This is a schematic diagram illustrating the working state of the training device for KOA-PT exercise provided in this embodiment of the utility model. Figure 8 As shown, this utility model also proposes a training device for KOA-PT exercise, including a training support frame for KOA-PT foot dorsiflexion training. The training support frame includes a base f1, a support f2, and a leg swing target belt f5. One end of the support f2 is connected to the base f1, and the other end is provided with a support platform f3. A standing area f4 is provided on the base f1. The support platform f3 includes an open receiving port f31. The components on both sides of the receiving port on the support platform f3 are support parts. The receiving port is located above the standing area f4. The two ends of the leg swing target belt f5 are installed on the target belt support f6. The leg swing target belt f5 is horizontally arranged above the front side and / or above the rear side of the standing area f4 in the patient's leg swing path. When the patient swings their leg and touches the leg swing target belt f5, the leg swing target belt f5 provides feedback of the target achievement signal.

[0065] The patient wears a foot dorsiflexion and plantar flexion training device and performs KOA-PT exercises in standing area 4. With each leg swing, the patient aims to touch the target leg swing band, swinging the leg forward and upward and / or backward and upward, ensuring the height of the leg swing and effectively improving the consistency and standardization of the leg swing. After the patient touches the target leg swing band, the band provides feedback that the patient has achieved the target, further enhancing the effectiveness of the leg swing exercise. At the same time, the interactive feedback received by the patient can psychologically boost the user's confidence in being noticed and recognized, making the seemingly monotonous leg swing exercise, which requires nearly a thousand swings, more interesting and sustainable.
