Objective: The aim of this study was to compare the effect of 8 weeks of core stability on swissball and suspension exercises on core stability and static and dynamic balance in women with non-specific low back pain (NSLBP).
Materials and Methods: Participated and randomly divided into three groups: ball exercise (BE) group (N=11), suspension exercise (SE) group (N=11), and control group (N=10), The BE group and the SE group performed their exercise protocols for 8 weeks (three sessions per week), During this period, the control group did not experience any exercise. The core stability, static and dynamic balance assessed Pre and Post-intervention using Functional test and Biodex Balance System respectively. The data were analyzed by repeated-measures ANOVA.
Results: The research findings showed that all of the factors were significant differences in the experimental group from pre-test to post-test, but this difference was not observed in the control group (P≤0.05). Based on the results of the intergroup comparison, core stability, static and dynamic balance were different significantly between experimental and control groups, but this difference was not observed between the two experimental groups (P≤0.05).
Conclusion: The results of this study indicated that despite the different means of endurance factors of stability, the 8 weeks of core stability on swissball and suspension exercises had a significant same effect on core stability and static and dynamic balance in women with NSLBP. Due to the different means from the pre-test to post-test, if both exercise protocols are performed in a longer duration, SE may be more effective in improving core stability. Also, BE may be more effective in improving balance due to the nature and shape of the ball. In future studies, it is necessary to be considered the Pendulum and Vector Resistance principle during SE.
