The main points of lumbar spine traction: lumbar spine traction treatment must master the direction of traction force (angle), weight and traction time three major elements. 1, traction mode: commonly used lumbar spine belt traction method, usually using supine traction. Supine traction is divided into continuous traction and intermittent traction. 2, traction angle: general supine flat traction, at the same time pay attention to adjust the angle combined with the patient’s condition. The patient is required to fully relax the lumbar region. Traction posture should make the patient feel comfortable, if there is serious pain, that should be adjusted as appropriate to help the patient find the best angle. 3, traction weight: mainly the muscles of the lumbar region. The weight of slow traction is generally 25%-70% of body weight. 4, traction time: traction time to continuous traction 10-35 minutes, intermittent traction is 20-40 minutes is appropriate, 1-2 times a day, 10-15 days for a course of treatment. 5, precautions: should take full account of individual differences, the elderly and frail should reduce the traction weight, shorten the traction time, the young and strong can increase the traction time and weight; traction process should pay attention to observe and ask the patient’s response, such as discomfort or aggravation of symptoms should immediately stop traction, find the cause and adjust the treatment plan. 6, traction treatment indications: (1) the first attack and the short duration of the disease patients, the general duration of the disease does not exceed 6 months. (2) Although the duration of the disease is long (more than 6 months), but the symptoms and signs of the disease are mild. (3) Those who are not suitable for surgery due to other diseases. 7. Contraindications to traction therapy: (1) Central lumbar disc herniation, pain and numbness in both lower limbs, with urinary and fecal dysfunction and numbness in the saddle area. (2) Lumbar disc herniation combined with lumbar isthmus discontinuity or with slippage. (3) Patients with lumbar disc herniation with significant general debility, such as cardiovascular system, respiratory system diseases, and patients with poor cardiopulmonary function. (4) Pregnant women with lumbar disc herniation and women during menstruation.
