Description

A leg swing rehabilitation training support frame and training device TECHNICAL FIELD

[0001] The present application belongs to the technical field of clinical medical devices and household rehabilitation exercise, and particularly relates to a leg swing rehabilitation training support frame and training device. BACKGROUND

[0002] The global society has entered an aging society, and the proportion of the elderly population is still increasing year by year. Knee joint degenerative disease has become one of the major disabling diseases in the world, seriously affecting the quality of life of the elderly. By the end of 2018, according to statistics, among the people over 65 years old, the proportion of people suffering from knee joint pain is more than 60%, 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 patients with knee osteoarthritis.

[0003] The knee joint is the most complex support leg weight-bearing joint in the human body, and is one of the joints most susceptible to damage. Knee joint disease is usually caused by lower extremity biomechanical line instability, lower extremity disuse atrophy, long-term incorrect body position (such as sitting and squatting), long-term lower extremity cold blood supply deficiency, joint cavity infection, intra-articular tissue primary and metastatic cancer, endocrine disorders osteoporosis, and exogenous high-energy injury, etc. A series of changes in histopathology and physiology of various tissues in the joint cavity, such as arthritis, osteoarthritis, synovitis, patellar softening, meniscus injury, subchondral bone sclerosis, and softening, etc. Knee osteoarthritis (KOA) is a chronic, functional and morphological degenerative joint disease. The earliest and most important pathological change is cartilage, followed by subchondral bone cystic lesions and marginal osteophytes. Finally, the normal joint surface is completely destroyed and deformed, resulting in increased pain, limited movement function, and even disability.

[0004] Modern clinical medicine proposes different treatment plans for KOA patients at different stages of K-L (Kellgren-Lawrence) classification. Total knee arthroplasty (TKA, UKA) is another major treatment method for KOA patients at the fourth stage of K-L classification, but this surgery is a destructive reconstruction surgery with greater damage and lower patient acceptance. At the same time, the muscle strength around the knee joint and the sensitivity of the lower extremity proprioceptor of the patient after knee arthroplasty cannot meet the needs of normal life and exercise, especially the whole system of the lower extremity proprioceptor is destroyed, which lays a long-term and endless disaster for the future constant falling in normal life.

[0005] At present, in the 'China Osteoarthritis Pain Management Clinical Practice Guide (Chinese Journal of Orthopaedics 2020 Edition)' has been selected as the 1A (strongly recommended highest level) choice for the treatment of KOA, and the patient is asked to do leg swinging exercise. Leg swinging can effectively treat knee pain and help patients recover quickly. However, the principle of leg swinging for effectively treating knee pain has not been clearly studied for a long time. In the patent document with the authorization announcement number CN113952677B and the name of 'Treatment and rehabilitation equipment for knee joint degenerative disease based on KOAPT therapy', Mr. Song Jiuhong, the inventor, first discovered that leg swinging exercise can drive the non-contact movement of the upper and lower articular surfaces of the knee joint and the contraction and relaxation movement of the synovial capsule around the knee joint cavity through the swinging of the hip joint; secondarily causes the intra-articular pressure to increase and decrease alternately; further promotes the secretion and absorption of synovial fluid in the joint cavity; thereby effectively removing various inflammatory factors and pain factors in the joint cavity; and because of the increase in joint synovial fluid circulation, it has a positive repair promoting trend for articular cartilage; overall, it relieves the symptoms of knee pain, and also provides a valuable pathophysiological basis for the repair of damaged articular cartilage. And in the patent document, KOAPT modern standard leg swinging therapy (Knee Osteoarthritis Pendulum Therapy, KOAPT) is first defined for this scientific discovery, and the corresponding pendulum leg swinging rehabilitation training device is launched. In particular, the scientific concept of 'Zhengshubi' (a proper ratio between correct and comfortable) is first proposed in the patent document. When 'Zhengshubi' is reached, the support assembly needs to support the user's limbs and reduce weight during the user's leg swinging, thereby reducing the load bearing of a single load-bearing leg, so as to achieve comfortable and sustainable leg swinging exercise. Through the training device combined with KOAPT therapy, the intra-articular pressure can be increased and decreased alternately to promote the secretion of synovial fluid in the joint cavity, thereby effectively relieving the symptoms of knee pain, while also efficiently exercising the muscle strength of the anterior and posterior flexor muscle groups of the legs and greatly improving the sensitivity of the lower limb proprioceptors. However, the leg swinging rehabilitation treatment device in the prior art has a complex structure, high cost, large space occupation, and is not convenient for widespread use by patients. The inventor of the present application found that the existing treatment and rehabilitation equipment still has defects in further in-depth research:

[0006] First, the standardization of the leg-swinging movement in KOAPT therapy is an important factor closely related to the treatment effect, and users cannot know whether the leg-swinging movement meets the standard when completing the leg-swinging movement, often ignoring the height of the leg-swinging movement, so that the leg-swinging movement is inconsistent and non-standard, resulting in poor treatment effect. The existing treatment and rehabilitation equipment collects the signals in the leg-swinging movement of the patient through a photoelectric sensor or a camera, and obtains whether the leg-swinging movement meets the amplitude requirement through signal analysis, but the collected signals have acoustic interference and light interference, and the actual analysis result is not accurate.

[0007] In addition, when the user completes the leg-swinging movement, the hands can be released to complete other matters under the premise of ensuring that the vertical line of the body posture is perpendicular and the body weight reduction meets the standard, which puts forward new requirements for the design of the leg-swinging rehabilitation training equipment. SUMMARY

[0008] In view of the shortcomings of the prior art, the present application provides a leg-swinging rehabilitation training support frame and training equipment to help users timely feedback the leg-swinging standard during KOA leg-swinging rehabilitation treatment, and to realize other activities while the patient is training the leg-swinging.

[0009] To achieve the above purpose, the present application designs a leg-swinging rehabilitation training support frame, which comprises a base, a support frame and a leg-swinging standard belt, one end of the support frame is connected with the base, the other end is provided with a support platform, a standing area is arranged on the base, the support platform comprises an open receiving port, the components on both sides of the receiving port on the support platform are support parts, the receiving port is arranged above the standing area, both ends of the leg-swinging standard belt are installed on the standard belt support frame, the leg-swinging standard belt is transversely arranged on the leg-swinging path of the user in front of and / or above the standing area, and the leg-swinging standard belt feeds back the standard signal after the user touches the leg-swinging standard belt when swinging the leg.

[0010] The user usually swings the leg forward and / or backward in a pendulum manner to achieve joint cavity pressure reduction or increase, thereby promoting the secretion of synovial fluid, so as to effectively relieve the symptoms of knee pain. Therefore, for the user to perform the leg swinging rehabilitation exercise, whether the leg swings forward and / or backward to the predetermined target position is the action requirement of whether the leg swinging rehabilitation training standard is reached. Therefore, the user can set a leg swinging standard belt in the leg swinging path above the front side and / or the back side according to the leg swinging amplitude required by the KOAPT therapy and the leg swinging position that the user can reach, so that the user swings the leg forward and / or backward above the front side and / or the back side with the goal of touching the leg swinging standard belt, so that the leg swinging height is guaranteed, and the consistency and standardization of the leg swinging are effectively improved. On the other hand, after the user touches the leg swinging standard belt, the leg swinging standard belt feeds back a standard reaching signal such as a tactile signal, an auditory signal, a visual signal, or an optical digital signal to the user. After the user receives the standard reaching signal, the user knows that the leg swinging action reaches the standard this time. If the standard is not reached, the user does not receive the feedback signal, and the user knows that the leg swinging does not reach the standard this time, and adjusts the next leg swinging to touch the standard belt. This setting improves the effectiveness and standardization of the leg swinging exercise. On the other hand, this constant standard reaching feedback interaction can improve the user's self-confidence in being concerned and recognized psychologically, so that the boring leg swinging exercise of nearly one thousand times becomes interesting and can be persisted.

[0011] Further, the vertical distance between the leg swinging standard belt and the upper surface of the base is 10-120 cm. By adopting the above technical solution, according to different user heights, leg swinging abilities, and requirements, etc., the height of the leg swinging standard belt corresponding to the upper surface of the base is different under different conditions, but within this distance range, the user can perform leg swinging with the leg swinging standard belt as the target, improve the consistency and standardization of leg swinging, and achieve a relatively optimal range.

[0012] Further, the vertical distance between the leg swinging standard belt and the upper surface of the base is 10-120 cm. By adopting the above technical solution, according to different user heights, leg swinging abilities, and requirements, etc., the height of the leg swinging standard belt corresponding to the upper surface of the base is different under different conditions, but within this distance range, the user can perform leg swinging with the leg swinging standard belt as the target, improve the consistency and standardization of leg swinging, and achieve a relatively optimal range.

[0013] Further, the vertical distance between the leg swinging standard belt and the upper surface of the base is 10-120 cm. By adopting the above technical solution, according to different user heights, leg swinging abilities, and requirements, etc., the height of the leg swinging standard belt corresponding to the upper surface of the base is different under different conditions, but within this distance range, the user can perform leg swinging with the leg swinging standard belt as the target, improve the consistency and standardization of leg swinging, and achieve a relatively optimal range.

[0014] Further, the support is provided with two, respectively located on both sides of the standing area, the standard belt support includes a connecting rod, the connecting rod is provided with two, one end of the connecting rod is fixedly connected with the support, and the free ends of the two connecting rods are fixedly connected with the two ends of the leg swinging standard belt. By adopting the above technical scheme, the leg swinging standard belt is fixedly arranged on the support through the connecting rod, so that the connection stability of the leg swinging standard belt is high, the device structure is compact, and the device is convenient to install, and it is convenient for a user located on one side of the support to preset the leg swinging standard belt on the leg swinging path before swinging the leg.

[0015] Further, the connecting rod is provided with an adjusting pivot at the connecting position with the support, and the connecting rod rotates around the axis of the adjusting pivot. By adopting the above technical scheme, the connecting rod can be adjusted in an arc line through the adjusting pivot, so that the height of the leg swinging standard belt from the upper surface of the base can be adjusted, thereby meeting the use requirements of different users in height, leg swinging ability and requirements, and improving the flexibility and application range of the device. The adjusting pivot can be any existing structure capable of adjusting the angle through the pivot, such as a damping pivot, a damping hinge and a damping hinge.

[0016] Further, the standard belt support includes a fixing frame, the fixing frame is arranged on the outer side of the support, the bottom of the fixing frame is fixed to the ground or the base, the top of the fixing frame is provided with two ends arranged at intervals, and the two ends of the leg swinging standard belt are fixedly connected with the two ends of the fixing frame. By adopting the above technical scheme, the position of the leg swinging standard belt is more flexible through the separately arranged standard belt support, and the fixing frame can be an adjusting structure with an extension rod, so that the vertical distance of the leg swinging standard belt from the upper surface of the base plate can be adjusted in the vertical direction, thereby adjusting the height of the leg swinging.

[0017] Further, the leg swinging standard belt is rotatably connected to the standard belt support in the elongated direction. By adopting the above scheme, the angle of the leg swinging standard belt can be adjusted, so that the leg contact area of the leg swinging standard belt with the user when swinging the leg is maximized, and the strength of the feedback standard signal to the user or the accuracy of the sensor identification is improved.

[0018] Further, the leg swinging standard belt is a touchable target, and the touchable target is one or more of a damping rope, a damping belt, a damping net, an elastic rubber band, a bell, and a kicking plate. By adopting the above scheme, the leg swinging standard belt is a tangible touchable target, when the user swings the leg and touches the leg swinging standard belt, the tangible features of the leg swinging standard belt can feed back the standard signal to the user in the sense of touch, and the leg swinging standard belt in the form of a tangible flexible target, especially the damping belt, can rebound to the user, provide power to the user when swinging the leg, reduce the difficulty of swinging the leg, and improve the efficiency of swinging the leg.

This setting does not occupy space, facilitates the user to pass through the area of the leg swinging standard belt to enter or leave the standing area, and improves the convenience and technological interest of the device.

[0020] Further, the leg swinging standard belt is an inductive belt of a photoelectric sensor, and further comprises a feedback assembly electrically connected with the photoelectric sensor. The feedback assembly sends an audio and / or video and / or visible light signal and / or tactile signal to the user according to a signal of the photoelectric sensor. By adopting the technical scheme, the leg swinging standard belt adopts an invisible sensor mode. When a user touches an inductive area of the photoelectric sensor, the photoelectric sensor sends a signal to the feedback assembly. After receiving the signal, the feedback assembly sends an audio or video standard signal of “drop” or “standard” or “you are great” to the user. The feedback signal is more direct and explicit. The leg swinging standard belt further improves standard reference and feedback and incentive effect without occupying space, facilitates the user to clearly know the standard condition, timely adjusts the leg swinging action, improves the standardization of the leg swinging, and improves the self-confidence of the user.

Further comprising a counting sensor, and the counting sensor is arranged at the two ends of the leg swing standard reaching belt 5, and the sensing head 7 faces the leg swing path of the user, and is used for collecting the leg swing times of the user.

[0077] The vertical distance between the leg swing standard reaching belt 5 and the upper surface of the base 1 is 10-120 cm. The present application collects experimental data of users with different heights and body shapes when performing KOAPT exercise therapy, and after measurement and analysis, it is obtained that for the population with a height range of 155-185 cm, the front swing leg: L1: 10-50 cm, D1: 50-85 cm, angle: 35-60 degrees; the rear swing leg: L2: 10-30 cm, D2: 45-65 cm, angle: 25-45 degrees, L represents the height difference between the heel of the person and the leg swing standard reaching belt 5, and D represents the horizontal distance between the heel of the person and the leg swing standard reaching belt 5. Therefore, the vertical distance between the leg swing standard reaching belt 5 and the upper surface of the base 1 is 10-120 cm, which is a reasonable range to reach the leg swing amplitude requirement, and 10-50 cm is the best interval.

[0078] The leg-swinging standard-reaching belt 5 can adopt a physical structure that is a tangible entity structure, including one or more of a damping rope, a damping belt, a damping net, an elastic rubber band, an elastic rubber band, a bell, and a kicking board.
