The power of lumbar traction is calculated in kilograms, for example, for a 60kg adult, the number of kilograms of lumbar traction varies from 1/10-1/2, that is, 1/10-1/2 of the body weight. if a person suffering from lumbar disc herniation and has a thin body, the strength of the first traction treatment can reach 1/10-1/6 of the body weight, which can avoid aggravating the symptoms This can avoid aggravating the symptoms and allow the patient to gradually adapt, and can also play an effective traction role. If the person is relatively strong, the first traction force can reach 1/8-1/5 of the body weight. As the number of traction gradually increases, the symptoms of lumbar disc herniation gradually reduce, and the traction force can gradually decrease. If the degree of lumbar disc herniation is not reduced and the symptoms are not reduced, the traction force can be gradually increased to 1/3-1/2 of the person’s body weight in order to play an effective therapeutic role.
