Description

Technical Field

[0001] This invention relates to the field of assistive device technology, specifically to a wearable gait training assistive device for patients with spinal cord injury. Background Technology

[0002] Gait training is a crucial part of the rehabilitation process for patients with spinal cord injuries. This is primarily because spinal cord injury impairs the nervous system, leading to decreased or lost motor control in the lower limbs, thus affecting walking ability. Gait training not only helps activate residual neural pathways and promotes the recovery of neuroplasticity, but also strengthens muscles, improves balance and coordination, and prevents complications such as muscle atrophy and joint stiffness. Through systematic training, patients can gradually rebuild their walking patterns, improve their daily living abilities, reduce dependence on caregivers, and thus improve their overall quality of life and psychological well-being. Furthermore, gait training can reduce the risk of pressure sores and circulatory disorders caused by prolonged bed rest, making it an indispensable part of rehabilitation medicine.

[0003] Existing gait training assistive devices for spinal cord injury patients often have several shortcomings. For example, many devices are rigidly designed and lack flexible adjustment mechanisms, making it difficult to adapt to the different heights, body types, and rehabilitation stages of patients, resulting in poor comfort during training and even the risk of secondary injury. Existing devices are also insufficient in terms of support and stability, easily causing patients to sway or fall, resulting in low safety; at the same time, the wearable components may be too cumbersome and inconvenient to adjust, affecting training efficiency. Therefore, we propose a wearable gait training assistive device for spinal cord injury patients. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a wearable gait training assistive device for patients with spinal cord injury. It can flexibly adapt to the differences in height and body shape of different patients through height adjustment components and adjustable connection design, enhance the stability of the overall structure through guide components and hanging components to prevent swaying or falling during training, and improve comfort and simplify the adjustment process through soft wearable components.
