Abstract

INTRODUCTION
This study was designed to compare the effects of a 12-weeks adjustment therapy & mat exercise program with a 12-weeks Gym-ball & mat exercise program on sEMG(surface electromyograph) and Cobb's angle of spinal in low back pain patients.
METHOD
Thirty-seven patients as a subject were volunteered to participate in this study and were randomly assigned to one of three groups, i.e., adjustment therapy & mat exercise complex treatment group(AG: n=15), Gym-ball & mat exercise complex treatment group(BG: n=12) and mat exercise group(CG: n=10), respectively. The pretest-midtest-posttest randomized-groups design was utilized in this study. In pre test, the sEMG(surface electromyograph) and the Cobb's angle were measured. The sEMG test included both sides back muscle activity difference during isometric back extension. The subjects in the AG group progressed adjustment therapy and mat exercise treatment, performed for 50 minutes per session, 3 times per week for 12 weeks, whereas the subjects in the BG group went through the Gym-ball and mat exercise training, performed for 60 minutes per session, 3 times per week for 12 weeks. The subjects in the CG group went through mat exercise treatment, performed for 30 minutes per session, 3 times per week for 12 weeks. In mid-post test, all variables were measured again as same manner as the pre test. The data collected in the pre, mid and post tests at the AG, BG and CG group was analyzed by utilizing RMD two-way ANOVA.
RESULT
1) There was statistically significant(p<.001) decrease in latissimus dorsi and erector spinae muscle in the AG group and the BG group but the CG group were no significant decrease in the both sides muscle activity difference. The result of Post-hoc test was CG> AG, BG. 2) The Cobb's angle was statistically significant(p<.001) decrease in the AG group and the BG group but the CG group were no significant decrease. The result of Post-hoc test was CG> AG, BG.
CONCLUSION
The result of Post-hoc test was CG> AG, BG. In short term care, the adjustment therapy & mat exercise complex treatment better than the Gym-ball & mat exercise complex treatment for reduce the low-back pain.
