Purpose : This study is to observe what Low Back Pain is relative with trunk position according to trunk tilting angle. Most people suffered from Low Back Pain. Thus We are going to analysis what muscle groups influence on Low Back Pain. Method : The subject of this study is consist of 58 adults who have any pain on the Low Back. The subjects performed using CENTAUR®, 3-D spinal stabilization training implement on each 0, 45, -45, 90, -90, 135, -135, 180 angles(-:left side, +;right side). Results : 1. Means of 0〫angle(flexion) are left side 72.18[kNm] and right 79.06[kNm] moment. 2. Means of 45〫angle(side olique flexion) are left side 66.55[kNm] and right 69.81[kNm] moment. 3. Means of 90〫angle(side flexion) are left side 47.80[kNm] and right 78.68[kNm] moment. 4. Means of 135〫angle(side olique extension) are left side 57.35[kNm] and right 58.69[kNm] moment. 5. Means of 180〫angle(extension) are left side 54.67[kNm] and right 54.43[kNm] moment. Conclusion : Trunk extensor group was more high moment about 15% than trunk flexor group. Trunk extensor group was more high moment about 3.14% than trunk flexor group. Trunk extensor group was more high moment about 2.4% than trunk side flexor group, more high moment about 2.4% and 11.31% than trunk left and right side extensor group.
