The most traumatic causes are car accidents, accounting for almost 50%, followed by falls from heights, crushed by heavy objects, slips, sports injuries, and knife and gun injuries. Wait. Patients with spinal cord injuries often lie in bed for a long time, or can only use wheelchairs for transportation. In the long run, the muscles in the parts that cannot move smoothly will gradually atrophy, which may eventually lead to the possibility of joint contractures that limit the range of motion. Furthermore, for patients who lie in bed for a long time, it is clinically recommended that such patients be given fixed-frequency, moderate-intensity joint range of motion and cardiopulmonary training. If there is no appropriate rehabilitation, it may still cause muscle damage Atrophy occurs. Especially for patients who have just been discharged from the hospital, lying in bed for a long time, the muscles cannot provide the strength required for walking, resulting in discomfort when walking, and may also cause convulsions.

In order to solve the muscle atrophy that is prone to occur in the above-mentioned disabled patients and patients who have just left the bed, some inventors have developed a "Modular standing frame" such as US Patent No. US8567808.
