1.Cervical 4 complete spinal cord injury: ※Functional disorder: except for the head, the patient can do free movement, the limbs and trunk can not move, daily life can not take care of themselves, and need the help of others. Rehabilitation strategy: (1) With the patient’s remaining head and mouth functions, train the patient to bite a small stick (mouth stick) or head to operate some instruments or do other activities. (2) Perform deep breathing, loud singing and talking exercises to strengthen the respiratory function. (3) Stand on an inclined bed and gradually raise the angle until it approaches 90 degrees. To slow down the occurrence of osteoporosis and favor the excretion of second stool. (4) Passive full-joint range of motion of all joints of the limbs to prevent stiffness of the limbs and joints of the hands and feet. Move each joint 10-15 times each time, at least once a day. 2.Cervical 5 complete spinal cord injury: ※Functional disorders: the patient can move the shoulder joint, the elbow joint can be actively flexed, but lack of elbow extension and all functions of the wrist and hand; poor respiratory function due to paralysis of intercostal muscles, complete paralysis of the trunk and lower limbs; unable to independently turn over and sit up; unable to wear assistive devices by themselves; most of the daily life needs the help of others. Rehabilitation strategies: (1) Strengthen the biceps muscle; learn to use a low-backed wheelchair and drive it on the level ground; use a motorized wheelchair if possible. (2) Learn to use the lasso fixed on the backrest of the wheelchair for forward leaning decompression; a spoon can be fixed on the patient’s hand to practice eating by oneself. (3) Respiratory function training, standing training, total joint mobility training. 3.Cervical 6 complete spinal cord injury: ※Functional disorders: the patient lacks the ability to extend the elbow and flex the wrist, the hand function is lost, and the rest of the upper limbs function is basically normal; the trunk and the lower limbs are completely paralyzed; the intercostal muscles are paralyzed, and the respiratory function is weakened. The patient can drive the wheelchair on the flat ground; use the bedrail to turn over; use the elbow flexor muscle to hook the rope ladder tied to the foot of the bed to sit up from the bed; use the universal cuff to finish eating, grooming, writing, typing, making phone calls, etc.. The patient can achieve a small part of self-care, and needs a moderate amount of help. ※Rehabilitation strategies: (1) Strengthen the biceps brachii and radial extensor carpi radialis muscle. (2) Training of driving wheelchair. (3) Unilateral alternating hip decompression for 15 seconds every half hour. (4) Sitting up in bed, standing up, breathing, and total joint mobility training. 4.Cervical 7 Complete Spinal Cord Injury: ※Functional disorders: the patient’s upper limb function is basically normal, but due to the incomplete innervation of the intrinsic muscle of the hand, there are certain obstacles in grasping, releasing and dexterity, and it is not possible to pinch; the lower limb is completely paralyzed; and the respiratory function is poor. The patient in general can basically be completely independent in a wheelchair; can independently operate a wheelchair on level ground; can turn over, sit up and move around in bed by himself; can feed, dress, undress and self-catheterize by himself; and can independently carry out all kinds of transfers. Patients can achieve most of the self-care in life and need a little help. ※Rehabilitation strategy: (1) Upper limb residual muscle strength enhancement training. (2) Sitting in a wheelchair can support both hands on the armrests for decompression, once in half an hour, 15 seconds each time; transfer with a skateboard. (3) Joint mobilization, breathing and standing training. 5.Cervical 8-thoracic 2 complete spinal cord injury: ※Functional impairment: the patient’s upper limb function is completely normal, but cannot control the trunk, both lower limbs are completely paralyzed, and respiratory function is poor. The patient can independently complete bed activities, transfer, drive a standard wheelchair, independently use communication tools, write, change clothes, can carry out light housework, daily life is completely self-care, can be engaged in seated work, and can stand with the help of a long lower limb support in a parallel bar. Rehabilitation strategies: (1) Use dumbbells, tensioners and other equipment to strengthen the upper limb muscle strength and endurance training. (2) Pay attention to practicing bracing decompression movement in sitting position. (3) Try your best to practice various wheelchair skills to improve the patient’s adaptability. (4) Transfer training, appropriate vocational training. 6.Thoracic 3 – thoracic 12 complete spinal cord injury: ※ Functional impairment: patients with upper limbs completely normal, intercostal muscles partially or completely normal, thus respiratory function is basically normal, partial paralysis of the torso, complete paralysis of both lower limbs. These patients can take care of themselves, use a standard wheelchair and complete transfer movements independently, carry out general household chores, and can engage in work in a seated position. Therapeutic walking training using long lower limb supports, crutches, walkers or balance rods. ※Rehabilitation strategy: (1) Perform the training done by patients with cervical 8-thoracic 2. (2) Perform mainly standing and therapeutic walking, which includes using long lower extremity supports, walkers, and double axillary crutches, practicing standing balance and walking inside the double bar, then practicing walking outside the bar, and practicing step-to-step for chest 6-chest 8, and step-over-step for chest 9-chest 12. 7, lumbar 1 – lumbar 2 complete spinal cord injury: ※ Functional disabilities: patients with completely normal upper limbs, trunk stability, respiratory function is completely normal, good physical endurance, most of the muscles of the lower limbs are paralyzed, they can carry out all the activities of the patients with thoracic 3 – thoracic 12, and they can carry out functional walking with the long lower limb support or short lower limb support and elbow crutches or walking cane at home, i.e., they can walk with the long or short lower limb support at home for a short distance and at a slow speed, can walk up and down stairs, and can carry out daily life activities. That is to say, they can walk short distances and at a slow speed at home with long or short lower limb braces, walk up and down stairs, and take care of themselves in daily life. Rehabilitation strategies: (1) Practice walking with a four-point gait. (2) Practice standing up alone from a wheelchair. (3) Go up and down stairs. Those with superior physical conditions should practice safe falling and getting up again. (4) Other training is the same as for patients with thoracic 3-thoracic 12 injuries. 8, lumbar 3 – lumbar 3 or less complete spinal cord injury: ※ Functional impairment: patients with upper limbs and trunk completely normal, partial paralysis of muscles in both lower limbs, the use of canes and wear high-top shoes can achieve the practical ability to walk, lumbar 5 or less injuries can also be achieved without any aids for the purpose of practical walking. Rehabilitation strategy: (1) The degree of disability of the patient is relatively light, rehabilitation training mainly focuses on the residual muscle strength training of both lower limbs, and sandbags, instruments and other methods can be used to improve muscle strength. (2) Practice four-point gait with double crutches and walking with a cane.
