Abstract

The invention relates to a double-UPS-type ankle rehabilitation device. The ankle rehabilitation device comprises a movable platform, two movement branch chains, a constraint branch chain, a constraint branch chain motor drive unit, a constraint branch chain synchronous belt transmission unit and a base, wherein the movable platform comprises an adjustable foot baffle plate, a vertical adjusting device, an upper platform and a lower platform, and the two movement branch chains which are symmetrically distributed and the constraint branch chain are connected with the movable platform and the base together. Due to the adoption of the structure, the demands of different patients for ankle rehabilitation can be satisfied, the constraint branch chain enables the movable platform to have three rotation freedom degrees, and enables the rotation center of the movable platform to always coincide to the movement center of the human ankle, and thus the risk that a patient suffers from secondary injuries is reduced. The height, away from the ground, of the movable platform is reduced, the patient can sit on a common chair for completing the rehabilitation treatment, the base bears most of theweight of the legs of the human body, thus the pressure caused to the movable platform by the feet is reduced, in match with the bearing capacity of the constraint branch chain, the rigidity of the device is increased.

Description

Technical field [0001] The invention relates to an ankle joint rehabilitation device, in particular to a parallel mechanism for assisting ankle joint rehabilitation treatment. Background technique [0002] The ankle joint is one of the weight-bearing joints of the human body, and it is also the pivot between the human body and the ground, which can help the human body complete a series of daily actions. Insufficient muscle strength, stability and coordination of the ankle joint make the ankle joint extremely vulnerable to injury in daily life. After the ankle joint is injured, it is not easy to heal, and it is easy to form swelling and chronic pain. Sports injured people, the elderly, due to cardiovascular and cerebrovascular diseases Patients with hemiplegia caused by the disease are common patients with ankle joint injury. Ankle joint injury not only affects the patient’s normal life and work. If the treatment is not timely or thorough, it can easily lead to secondary sprains, ...
