The Short effects of two spinal stabilization exercise on balance tests and limit of stability in men with Non - Specific Chronic Low Back Pain: Randomized Clinical Trial Study

This study investigated the short-term effects of two stability exercises including Abdominal Hollowing and Abdominal bracing on stabilization parameters of Biodex Stability System in male subjects with non-specific recurrent low back pain. This Randomized Clinical Trial and case – control study was performed on 30 male subjects with non-specific recurrent low back pain by sample of convenience and randomly allocated to 3 control group (10 subject) and 2 experimental group (10 subject). Dynamic balance stability indices (Overall, Anterior–Posterior and Medial–Lateral) and Limit of Stability were measured by using Biodex Stability System before and immediately after exercise. All data by cross over, one way analyze of variance (one way ANOVA) and t-test was analyzed. Our finding showed that all indices except with Medial–Lateral were increased significantly in experimental group in comparison with control. In Abdominal Bracing group, both level of stability of 8 and 3, showed a significant reduction (P<0.05). Limit of Stability in both experimental groups with abdominal Hallowing (P= 0/001) and Abdominal Bracing (P= 0/01) increased significantly. The findings revealed that one session training affects increase balance due to muscle activity improvement.
