Technical field

The present application relates to the technical field of rehabilitation equipment, specifically, to a multi-position upper and lower limb rehabilitation training walker.

Background technique

Stroke is a common disease that seriously affects the quality of human life. Due to damage to the central nervous system, patients recovering from stroke often have abnormal gait problems caused by muscle spasm, poor posture control, poor motor control, and weakened core muscle strength. Walking is the goal that most stroke patients hope to achieve, so improving walking function is particularly important. Lower limb motor function, including walking function, is the dominant factor for hemiplegic patients to resume daily life and gain the ability to live independently. Improvement of walking function can significantly improve the patient's mental health and quality of life.

Clinically, it is common for stroke patients to shorten the weight-bearing time of the affected lower limb during walking. Most therapists use weight transfer training, single-leg weight-bearing and other methods to improve it, but the effect is not ideal. The main reason is that the patient has difficulty in walking. When the center of gravity changes during the process of self-dynamic balance adjustment, especially when one lower limb is bearing weight, the stability of the body posture requires not only the strength of the affected lower limb to bear weight, but also relies more on deep muscles such as the internal and external abdominal obliques and rectus abdominis. contraction, and through the range and maintenance time of the stability limit before and after training, the muscle strength, coordination and flexibility of the above muscle groups can be improved. Therefore, by maintaining the stability limit for a certain period of time, the patient's body is induced to adjust at the stability limit, thereby activating the deep muscles of the trunk, improving the strength of multiple key muscle groups, and improving core control capabilities, thereby improving walking stability. The swing of the upper limbs is not only inertia, but also comes from the active regulation of the nervous system. The swing of the upper limbs during walking can improve walking stability and improve the patient's postural stability during walking. Through the patient's active upper limb swing, from the initial free flexion and extension of the shoulder joint in a small range of back and forth swing to the free and active upper limb swing in the later stage, the coordination of the upper and lower limbs can be improved, walking stability can be increased, and balance function can be improved.

Existing rehabilitation training walkers only focus on the adjustment of the lower limbs, but do not care about the adjustment of the upper limb position, resulting in poor rehabilitation training effects.
