However, by sitting in a chair for a long time with the same posture, such as an increase in desk work for a long time toward the personal computer, the upper body weight is applied to the lumbar spine of the lumbar region, especially for people with chronic or mild back pain, The burden on the lower back is heavy, and depending on how you sit down, the disc may be damaged.

  As an ideal way to sit on a chair, as shown in FIG. 5, the chair is placed on the back of the chair tilted at 10 degrees so as to push the sacrum and lumbar spine, and the back is leaned against the back. Sit on. At that time, put the foot of the chair so that the height of the lower leg is horizontal in front of the chair and put your feet on it. It is said that the burden on the waist can be reduced by 25% by sitting on the chair with the elbow placed on the armrest of the chair.

  Methods for treating low back pain include drug therapy, lower body traction therapy, surgical therapy by surgical treatment, orthosis therapy by wearing a corset, and exercise therapy for strengthening the abdominal and back muscles. For example, as shown in FIGS. 6 and 7 as a therapy by pulling the lower body, a pelvic band 52 to be attached with a buckle 56 to the pelvis of a patient with back pain supine on the bed 50, one end attached to the pelvic band 52, and the other end It is connected to a winding device or a weight (not shown) through side bands 53 and 53 attached to the enlargement rod 54 and a pulley (not shown) installed on the foot side of the bed whose one end is hooked to the enlargement rod 54. There is a pelvic traction device comprising a pulley rope 55 provided.

The pelvic traction device is used for treatment as a therapy by traction of the lower body in orthopedics in the following manner. A patient with back pain stands with his knees on the bed 50 and supine, and the upper body is fixed to the bed through upper body fixing bands 51 and 51 fixed to the head side of the bed under both sides.
Next, the pelvic band 52 is attached to the patient's pelvis with a buckle 56, and the other ends of the side bands 53, 53 attached to the pelvic band 52 are attached to both ends of the expanding bar 54. One end of a pulley rope 55 connected to a take-up device (not shown) or a weight is hooked on the expansion bar 54 via a pulley (not shown) installed on the foot side of the bed. The weight of the weight is appropriately adjusted according to the patient's symptoms, and the traction force and the pulling time of the pulley rope 55 are also adjusted according to the patient's symptoms.
