A trunk rotating exercise was developed for chronic low back pain patients. Total 13 (5 male and 8 female) patients were involved in this study, clinical outcomes were investigated at 1 month after starting the therapeutic exercise. The exercise is very simple and easy to perform. While sitting on a chair, a patient was asked to rotate his or her body trunk as much as possible and stay at the rotated position for 3 seconds. Then let the patient turn to another direction and do the same way. Five to ten times right and left rotations were required in one set. Patients were asked to do it for three sets a day (one set for each morning, afternoon and evening). Nine patients (70%) had a good result at one month after doing the exercise. This exercise was supposed to have a stretching effect for back muscles surrounding lumber spine.
