Abstract

As an important supplement, rehabilitation training assistive device has a significant effect on the improvement of limb dysfunction in patients with hemiplegia. Most of the assistive devices supply patient with passive movement, which is unable to effectively meet the needs of active lower limb rehabilitation training. To solve this problem, an active rehabilitation training assistive device is developed. Using anthropometry, the static and dynamic dimensions of the assistive device is analyzed to decide the constraints of motion space. The change of foot pressure is selected as the trigger condition of assistive assistance compensation, and the patient - device interaction process is developed based on this. Patients and normal controls are selected for comparative experiments. Walking gait data of healthy leg and affected leg, patient and normal control, affected leg and assistive device correction are collected separately. Compare these groups of data, it can be seen that the main gait parameters of the patient's affected leg after correction have been significantly improved, and are basically consistent with the healthy leg and close to the normal control. The function of the assistive device prototype and the effectiveness of auxiliary training are verified.
