Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a wearable assistive device for rehabilitation therapy. Background Art

[0002] Patients with central nervous system injuries such as stroke and brain trauma often suffer from abnormal posture, uneven weight bearing on both lower limbs, difficulty in shifting the center of gravity, and decreased balance due to sensory and motor dysfunction, leading to walking dysfunction. Trauma, fractures, peripheral nerve damage, sensory integration disorders in the elderly and other diseases can also lead to a decrease in lower limb weight bearing and walking function. During the treatment process, the therapist corrects the patient through proprioception stimulation or visual compensation. Once the therapist's assistance or reminder is gone, the patient is separated from the large training equipment, or loses the support of the treatment environment, and the patient is often unable to independently, effectively and correctly complete the safe distribution of weight bearing ratio on both lower limbs. This may lead to problems such as the inability to perform walking training independently or the weight bearing on the affected side is too high or too low during training, making the training ineffective or posing a risk of falls that hinders the rehabilitation process. Summary of the Invention
