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 the result of an external blow to the spine that causes a vertebral fracture, resulting in damage to the spinal cord. It can also be a consequence of diseases such as myelitis, spinal cord tumors, and spinal cord vascular lesions. 1, paralysis: injuries to the chest and waist lead to paralysis of the lower extremities, and injuries to the neck can lead to quadriplegia. 2, sensory impairment: paralyzed limbs are usually accompanied by corresponding sensory impairment or even loss. 3.Incontinence: urinary incontinence is very common, and there is often difficulty in urination. Constipation, can also be incontinent. 4, pain: many patients appear to have pain below the site of injury. 5, muscle spasm: spinal cord injuries above the waist often appear muscle spasm, affecting limb movement, care, and sometimes can cause pain. 6, pressure sores (bedsores): is the most common spinal cord injury complications, can lead to infection and activity disorders. 7, psychological disorders: most patients have varying degrees of psychological disorders, and thus aggravate the condition. 8, other: infection, autonomic dysregulation, heterotopic ossification, breathing difficulties, etc. The sooner you start rehabilitation after spinal cord injury, the better. Generally, 7-10 days after fracture fixation or spinal trauma, non-traumatic spinal cord injury (myelitis, etc.) can be treated in the rehabilitation medicine department when the condition is stable (usually around 10 days). As for the early treatment at the bedside, it should be done even earlier. Early treatment can effectively avoid comorbidities such as pressure sores, pneumonia, urinary tract infections, etc., and can also effectively improve the patient’s state of mind. Patients with spinal cord injuries have a strong potential for recovery from rehabilitation. Early recovery is generally completed within a few days to 6 months. Patients may also have further opportunities for 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.
