The spinal cord is the channel that connects the central nerves to the peripheral nerves and is a key link in transmitting commands from the brain to all parts of the human body. A spinal cord injury is usually caused by an external blow to the spine, resulting in a vertebral fracture that causes damage to the spinal cord. It can also be the result of diseases such as myelitis, spinal cord tumors, and spinal cord vascular lesions. First, the main functional disorders of spinal cord injury 1, paralysis: thoracic and lumbar spine injury leads to paralysis of the lower limbs, cervical spine injury can lead to quadriplegia. 2, sensory impairment: paralyzed limbs are usually accompanied by corresponding sensory impairment, or even loss. Urinary and fecal incontinence: urinary incontinence is very common, or there is difficulty in urination. The bowels are usually constipated and can be incontinent. Repeated urinary catheterization often causes urinary tract infection. 4.Pain: Many patients experience pain below the injury site. 5, muscle spasm: spinal cord injury above the waist often appear muscle spasm, or have pain, affecting limb movement. 6, pressure sores (bedsores): the most common complication of spinal cord injury, which can lead to infection. 7, psychological disorders: most patients have varying degrees of psychological disorders, and this aggravates the condition. 8, other: autonomic dysregulation, heterotopic ossification, breathing difficulties, etc. Second, the timing of spinal cord injury rehabilitation treatment Generally speaking, the earlier the timing of starting rehabilitation treatment after spinal cord injury, the better. Early treatment at the bedside should be carried out even earlier. Early treatment can effectively avoid comorbidities and effectively improve the patient’s state of mind. Generally, rehabilitation can be started 7-10 days after fracture fixation or after spinal trauma, when the condition of non-traumatic spinal cord injury (myelitis, etc.) is stable (usually around 10 days). Third, the potential of spinal cord injury rehabilitation therapy Patients with spinal cord injury have a strong potential for recovery. Generally, the early recovery process is completed within a few days to 6 months. Patients can also have further recovery in the following 2 years or so. The presence of early movement of the distal limb, such as active movement of the toes, often predicts good recovery potential. It is important to note that spastic movements are of no prognostic value. Those with sensation in the paralyzed area have a better chance of recovery of motor function. Areas with normal sensation have a greater than 50% chance of motor recovery. Active participation in functional exercise is the most powerful recovery factor. Every patient has to make a 100% effort for a 1% hope. Even with a long history of disease, there must be tremendous potential to be realized without rehab, and that is the value of rehab.
