Description

Technical Field

[0001] The present invention relates to the technical field of sports rehabilitation equipment, and particularly relates to an ankle-linked motion rehabilitation assistance device. Background Art

[0002] The ankle refers to the protrusions on both sides of the part between the calf and the foot, which are formed by the enlarged parts at the lower ends of the tibia and fibula. Ankle joint sprains are the most common in sports injuries, mostly caused by the body losing balance, stepping on someone else's foot when landing, or being tripped. When sprained, the local area will have joint swelling and pain, and in severe cases, even cause fractures. Medical theory and practice have proven that patients with ankle joint injuries need to carry out limb training to restore limb function, prevent muscle "disuse" atrophy and joint stiffness. Appropriate and scientific physical exercises have a positive effect on the rapid healing of injuries and the promotion of functional recovery. Therefore, some ankle rehabilitation instruments have emerged on the market.

[0003] The main rehabilitation training for the ankle joint is plantar flexion, dorsiflexion, inversion, and eversion movements of the joint, which are the main movements for exercising the ankle joint. Through active functional training, the adhesions around the joint are loosened, and the range of motion of the joint increases.

[0004] However, the existing ankle motion rehabilitation equipment has a relatively simple composition structure, lacks a certain vibration massage structure on the rehabilitation equipment, and lacks a certain adjustment and fixation structure on the rehabilitation equipment, thus affecting the use effect of the rehabilitation equipment.
