PURPOSE: This study aimed to compare the effects of side-lying hip abduction exercise with and without vibration on pain, disability, strength and balance in individuals with low back pain.
METHODS: 30 participants enrolled in this study were randomly assigned to an experimental group (EG, n=15) for side-lying hip abduction with vibration and a control group (CG, n=15) for side-lying hip abduction without vibration. Both groups were treated 3 times per week for 4 weeks. Pain (Numeric Rating Scale), disability (Korean Oswestry Disability Index), hip abductor muscle strength, and static balance were measured in both groups before and after the program. Results were analyzed using paired t-test for comparing the difference within the group and independent t-test for comparing the difference between two groups.
RESULTS: Compared to the CG, the EG showed significantly greater reductions in pain and disability (p<.05). There was a significant difference in all balance categories of both the painful and non-painful sides within the EG (p<.05). Balance showed a significant decrease except the envelope area (ENV) on the non-painful side within the CG (p<.05). There was a significant increase in all balance categories except ENV of non-painful side between the two groups (p<.05). Balance increased on both the painful and non-painful sides in the EG. Balance improved on the painful side in the CG, but significantly decreased on the non-painful side (p<.05).
CONCLUSION: Side-lying hip abduction exercise with vibration is considered an effective treatment for pain, disability and balance in individuals with low back pain.
