Device and method for internal and external rotation rehabilitation training of ankle

Abstract

The invention discloses a device and method for internal and external rotation rehabilitation training of an ankle. The device comprises a bearing mechanism, a driving part, a transmission part and a detection part. The bearing mechanism comprises a base supporting frame, a supporting plate and an angular contact ball bearing. The driving part comprises a motor and a speed reducer. The transmission part comprises a small gear, a large gear and a worm and gear. The detection part comprises a two-axis torque sensor and an encoder installed on the motor, wherein the two-axis torque sensor is composed of a torque sensor and four force sensors. According to the device and method for internal and external rotation rehabilitation training of the ankle, the internal / external rotation single joint rehabilitation training of the ankle of the human body can be achieved; through application of the two-axis torque sensor composed of the torque sensor and the four force sensors and the encoder, patients' torque, motion positions and the like in the training process can be obtained, rehabilitation training and information detection functions are integrated, the basis is provided for a rehabilitation evaluation system, and the device is simple in overall structure, easy to produce and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an ankle joint internal and external rotation rehabilitation training device and method. Background technique [0002] The problem of aging in my country is becoming more and more serious, and stroke hemiplegia is a high incidence among the elderly, so the rehabilitation treatment for the elderly after hemiplegia is particularly important. The ankle dorsiflexion disorder of hemiplegic patients cannot overcome the foot drop in the walking swing phase, which seriously affects the recovery of their walking ability. Therefore, the rehabilitation of ankle joints is of great significance to the overall rehabilitation of hemiplegic patients. [0003] The traditional rehabilitation methods for hemiplegic patients need to be carried out by physical therapists, which consumes a lot of time and physical strength, and cannot guarantee sufficient training time and sufficie...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the traditional ankle joint hemiplegia rehabilitation workload, low efficiency, incomplete training of ordinary rehabilitation equipment, single training mode, and lack of patient training motion data detection in the prior art, the present invention provides a rehabilitation training for internal and external rotation of the ankle joint The device and method provide a patient passive and active training platform for patient training, and at the same time objectively detect and monitor the patient's movement state, providing an objective basis for doctors' follow-up treatment
