The purpose of this study was to determine whether unstable surface core exercise is more effective than stable surface core exercise on improving functional movement and balance and reducing pain in sedentary female workers with backpain. Participants were randomly assigned to an unstable surface core exercise(UEG; n=10) or a stable surface core exercise(SEG; n=10) group. They participated in the given exercise for 8 weeks. FMS, Y-Balance and VAS were measured before and after the participation in exercise, which were subjected to a repeated-measures ANOVA. In the case of a significant interaction between time and group, paired sample t-tests were conducted for a post hoc analysis within each subject group. Results indicated that FMS of the UEG had a significant effect on HS (p<.01), ASLR (p<.05) and TS(p<.001), but not for other variables. YBT did not show a significant effect for any variable (AT, PL, PM, TS), although the main effect of time was significant in both subject groups. VAS had a significant effect only in the UEG(p<.001). Our findings indicate that compared to SEG, UEG is more effective for improving functional movement and reducing pain, but not for improving balance, in sedentary female workers with backpain.
