Description

Technical Field

[0001] This utility model belongs to the field of walking aid technology, specifically relating to a walking aid for hemiplegic patients. Background Technology

[0002] Hemiplegia, also known as paralysis of one side of the body, refers to motor dysfunction of the upper and lower limbs, facial muscles, and lower part of the tongue on the same side. It is a common symptom of acute cerebrovascular disease. Patients with mild hemiplegia can still move, but when walking, the upper limb is often flexed and the lower limb is extended; the paralyzed lower limb makes a semi-circular movement with each step. This distinctive gait is called hemiplegic gait. Severe cases often result in bedridden patients who lose their ability to live independently. Based on the degree of hemiplegia, it can be classified as mild paralysis, incomplete paralysis, and complete paralysis.

[0003] After treatment, hemiplegic patients often use walking aids to facilitate rapid recovery. Walking aids, also known as lower limb orthoses, are a type of walking support tool used by elderly people with mobility issues, certain injured individuals, hemiplegic patients, and people with disabilities to help themselves walk or exercise their limb strength. People can walk slowly and easily while holding onto them.

[0004] Existing walking aids are all one-piece fixed structures that cannot be folded and do not have a seat structure. They only have simple walking assistance functions and are not perfect. Therefore, we propose a walking aid for hemiplegic patients. Utility Model Content
