Background technique

With the advancement of modern medical technology and the improvement of medical level, the average life expectancy of human beings continues to extend, but at the same time, there is an increasingly serious problem of population aging. The aging of the population is accompanied by the decline of human physiological functions, which in turn leads to a decline in the mobility and flexibility of the limbs, and even the loss of walking ability. In addition, there are more and more patients with hemiplegia and paraplegia due to diseases or accidents such as stroke, spinal cord injury, brain injury, and brain tumor, which lead to impaired exercise ability, and there is a clear trend of younger age. People with lower extremity dysfunction need external equipment or paramedics to assist with daily walking activities or walking rehabilitation due to limb injury or limited mobility. For the patient, there is also difficulty with trunk control, which prevents the body from standing upright. In the case of necessary postural conversion, the nursing staff needs to support the patient's chest and waist and correct the posture.

However, due to the scarcity of nursing staff and the high cost of nursing care, artificial assistance cannot meet the needs of patients in daily life. Therefore, it is necessary to use a walker to assist patients in meeting their daily walking needs. According to different functions and structures, existing walker products can be divided into three categories: unpowered walkers, functional electrical stimulation walkers and powered walkers. Unpowered walkers can be divided into walking sticks and walkers, among which walkers are divided into two types: walking and wheeled according to the traveling mode of the product. Unpowered walkers are more flexible and lightweight, have wider application range and are universal, but have the defects of single function and low safety.
