Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a multifunctional ankle-foot orthosis. Background Art

[0002] As the incidence of cerebrovascular diseases shows an upward trend, more than 70-80% of stroke patients cannot live independently due to disability. Evidence-based medicine confirms that stroke rehabilitation is the most effective way to reduce the disability rate. Most patients after stroke will experience some degree of muscle spasm. The continuous contraction of spastic muscles will cause pain, limited joint movement, contracture and joint deformity, which will affect the patient's motor function, daily life self-care ability and rehabilitation training process, bringing huge economic pressure and psychological burden to patients, families and society.

[0003] Therefore, it is particularly important to provide physical therapy rehabilitation training for patients. However, simple physical factors or techniques cannot solve the joint deformities caused by spasms in patients, and orthopedic equipment is needed to assist in the correction of the corresponding joints. Existing ankle-foot orthopedic shoes are fixed at 90°. Because the muscle tension of patients varies at different stages after a stroke, existing orthopedic shoes cannot adjust the angle required for the current condition in a timely manner according to the actual degree of improvement of the patient's condition. Since most patients who use orthopedic shoes have difficulty in moving, replacing orthopedic shoes requires the patients themselves to go on-site to make them, and the cost of custom-made orthopedic shoes is relatively high, so there is an urgent need for an orthopedic shoe that can adjust the angle.
