Background
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be taken as an acknowledgement or any form of suggestion that this information constitutes prior art that is already known to a person skilled in the art.
Stroke refers to a group of diseases that brain tissue is damaged due to sudden rupture of cerebral vessels or blood flow failure due to vessel occlusion, and clinical symptoms include dizziness, headache, numbness of limbs, slurred speech, hemiplegia, etc.
When a patient suffers from stroke and sits or stands early to resist gravity, the shoulder joint can be subluxated, so that the affected arm can be hung on the side of the body for too long time, and the affected arm can feel downy and painful. This pain sensation can be relieved immediately when the upper limb is lifted passively or when the affected limb is supported on a table in front of the body.
After the patient has suffered a stroke, the patient needs to frequently queue up for examination and queue up for rehabilitation therapy during hospitalization, and the patient cannot walk by himself or herself and only can rely on a wheelchair during the examination and rehabilitation therapy. Therefore, the time that the patient is in the wheelchair is a large fraction of the time. When the patient sits on the wheelchair, the patient can put the arm on the armrest of the wheelchair to relieve the pain and the half-dislocation of the shoulder joint. The existing wheelchair armrests cannot be adjusted, the sizes of wheelchairs in hospitals are basically the same, patients have obvious individual differences, and the comfort of the patients is influenced when the body sizes of the patients are larger or smaller, so that the rehabilitation degree is influenced to a certain extent.
In addition, in the spastic phase of stroke, the muscle tone gradually increases and becomes a spastic hemiplegia, accompanied by abnormal movement patterns, such as the flexor muscle of the upper limb being heavier than the extensor muscle, resulting in the inability of the patient to place the affected limb on the armrest of the wheelchair.
