Although patients with mild hemiplegia can still move, they often walk with their upper limbs flexed and their lower limbs straight. The paralyzed lower limbs draw a half circle with each step. This special walking posture is called hemiplegic gait.
[0003] When existing hemiplegic patients use lower limb assistive devices, the heights of the assistive devices required are different because different patients have different heights. Most of the existing assistive devices cannot be adjusted in height, causing inconvenience in use. In addition, the armrests on the existing assistive devices are mostly set horizontally, which is not conducive to patients' grasping and exerting force, causing inconvenience in use.
