Paraplegia, also known as spinal cord injury, is the damage to the structure and function of the spinal cord caused by various reasons, resulting in motor, sensory, and autonomic dysfunction under the plane of injury, and the injury above the cervical segment is called high paraplegia. At present, the main cause of spinal cord injury in China is car accidents and traffic accidents, which are characterized by young age (about 80% of young patients under 40 years old, and about 4 times as many men as women) and high disability rate. The incidence of paraplegia is on the rise with the high speed of transportation, the extreme of sports and the emergence of violent injuries. For a long time, people think that paraplegia is an irreversible functional injury, mainly manifested as loss of consciousness in both lower limbs, inability to walk, incontinence, etc. Many patients do not know enough about the disease and one-sidedly think that paralysis is equal to loss of working ability and it is impossible to stand up and walk again in their lifetime, so they pessimistically give up treatment and lead to lifelong inability to take care of themselves. Modern medicine confirms that scientific rehabilitation treatment and care can not only restore the function of limbs to the greatest extent, rebuild patients’ confidence in life and achieve self-care, but also effectively prevent the occurrence of various complications. The rehabilitation of respiratory function and bladder function can prevent the occurrence of infection. There are many aspects of rehabilitation for paraplegic patients, including motor function rehabilitation, sensory function rehabilitation, respiratory function rehabilitation, bladder function recovery, psychological rehabilitation, selection of prosthesis, and use of wheelchair. After early stabilization of the spine, patients can perform active functional exercises such as posture change and turning under the guidance of a doctor, and perform standing training on an electric bed as early as possible to lay the foundation for walking training. The earlier a paraplegic patient starts rehabilitation, the better. Generally, 7-10 days after spinal trauma, non-traumatic spinal cord injury (such as myelitis, etc.) is stable (around 10 days), then rehabilitation can be carried out. The most effective time for rehabilitation is within 6 months. Early onset of early movement of the distal limb, such as active movement of the toes, often predicts good recovery potential. Those with sensation in the paralyzed area have a better chance of recovering motor function, and those with normal sensation have more than a 50% chance of recovering motor ability. Even for patients with more than 2 years of disease, it is possible to recover walking through comprehensive rehabilitation therapy with assistive devices.
