Research progress on the application of shoulder orthosis in rehabilitation of abnormal gait post-stroke hemiplegia

Post-stroke hemiplegia usually has an adverse impact on motor ability and stability. Patients often develop shoulder subluxation and abnormal gait due to muscle weakness， bilateral limb muscle tension imbalance， sensory abnormalities and poor joint and posture control， etc. Shoulder orthosis is often used to prevent or treat shoulder subluxation in the early stage of stroke hemiplegia， but it is still controversial. To explore the role of shoulder orthosis beyond the prevention and treatment of shoulder subluxation， and to provide theoretical basis for the selection and wearing of shoulder orthosis，the mechanism underlying the role of shoulder orthosis in improving abnormal gait post-stroke hemiplegia was elaborated， and the effects of different types of shoulder orthosis on the rehabilitation of abnormal gait post-stroke were compared
