1, posture: avoid long-term sitting, too soft and too short chairs and stools, bending and heavy work and bad sleeping posture. For example, long-time desk workers, computer workers and long-term drivers are highly affected by lower back pain, should avoid long hours of sitting work, in order to reduce the occurrence of lower back pain. 2, exercise: exercise is an important measure to treat lower back pain, good flexibility can prevent stress concentration in the lower back segment, and patients who are not fit enough are more likely to have lower back pain. 3, weight control: overweight on the paravertebral muscles and the spine cause greater stress, spinal cord injury patients due to the loss of motor ability, reduced calorie consumption and weight gain. 4, quit smoking: Smoking is a risk factor for lower back pain, especially in people under 45 years old. Chronic coughing leads to increased pressure within the intervertebral disc. Functional vasoconstriction or atherosclerosis caused by smoking hinders the blood supply to the spinal cord; absolute high changes in oxygen-carrying and oxygenation capacity caused by smoking leads to intervertebral disc nutritional disorders; reduced cellular uptake of nutritional substrates caused by smoking; the proportion of degenerative disc degeneration is high in the smoking population. 5. Limit alcohol consumption: Alcohol abuse is associated with deterioration of muscle strength and a history of muscle damage; falls can lead to further tissue damage, and alcohol abuse is rarely able to perceive damage. Objectives: Attempt to relieve pain with nerve root lesions, strengthen lumbar extensors and abdominal flexors, strengthen weak muscles, pull tense muscles, perform aerobic exercise, review and educate patients on maintaining good physical function, indoor activities, ergonomic assessment during work or exercise, emphasize specific functional activities (e.g., walking, daily activities, housework, etc.) Note: Overcome “no pain, no gain” concept, spinal stenosis or slipped vertebrae – avoid trunk hyperextension, osteoporosis – avoid trunk twisting or rotation.
