Whether paraplegia can walk or not is related to the acute stage with the cause and treatment situation, and the recovery stage is mainly related to ASIA score and residual muscle strength. 1. Etiology and treatment: paraplegia can be caused by a variety of reasons, such as transverse myelitis, optic nerve myelitis, spinal cord tumors, spinal cord trauma, etc. If timely treatment is given, part of the function can be restored and walking is possible. If the paraplegia is caused by transverse myelitis, optic nerve myelitis, etc., most of the patients can recover and walk if they are given timely treatment such as hormone shock therapy, nerve nutrition and physical therapy rehabilitation. If spinal cord trauma is the cause, timely surgical treatment may also result in functional recovery and the ability to walk. Regardless of the cause of paraplegia, it is unlikely that paraplegic patients will be able to walk if they are not treated effectively and in a timely manner. 2. ASIA Score and Residual Muscle Strength: According to their ASIA classification, 85% of Grade A patients will not regain function, and of the 15% of Grade A patients who do regain function, only 3% will regain some motor function. More than half (54%) of grade B patients and the vast majority (86%) of grade C-D patients will fully regain most function. Those with residual muscle strength grade 3 and above have the potential to return to walking with active rehabilitation. In the presence of paraplegia, prompt medical treatment should be sought and followed by active rehabilitation to minimize the sequelae.
