Introduction: Chronic low back pain is one of the most common diseases causing a lot of problem for individuals. Cause of 97% back pains is Mechanical,1% Non-mechanical and also 2% is due to Visceral disease that meanwhile Disc Herniation ,inter-vertebral 4% is from Mechanical low back pains. Therefore, the goal of this research was Comparing core stability exercises on in Stable and unstable surfaces on women's pain and disability affected by chronic low back pain caused by lumber disc herniation
Methodology: Thirty seven female patient with chronic Lumbar Disc Herniation with mean age 37 years were selected by convenience and purposive and then into 3 groups. 1- Core stability exercises on stable surface (on the ground) 2- unstable surface (physio-ball) and 3- control group. The average scores pain and disability were recorded in pretest and post test by VAS index and Oswestry Disability Questionnaire. Information evaluated by using Repeated Measures ANOVA.
Results: The results showed that pain and disability in experimental groups Comparing to the control group, reduce significantly (P=0.001). Moreover the results showed that there is a significantly differences in disability average in stable than to unstable group (P=0.001) that this differences despite higher average was not significantly (P=0.740).
Discussion: According to the results, core stability exercises on both surfaces, with improved strength and endurance of the core region can be reduced additional loads exerted on the lumbar spine and improve performance. One of the possible mechanism for effectiveness of exercise on unstable surface is increased simultaneous contraction with exercise on physio-ball which caused more stability in joints and possible mechanism for stable surface could by improving changeability strategies involved in Postural control and also reinforcement proprioceptor of lumbar region (lumbosacral) by improving strength, flexibility, muscle balance that eventually cause reduce asymmetric forces push on joint surface and discs.
