Purpose Altered movement patterns and spine instability are important factors in the etiology of chronic non-specific low back pain (CNSLBP). The faulty recruitment pattern of core muscles causes poor support and increased loading on the lumbar spine and ultimately leads to postural instability. The aim of this study is the effect of core stability exercises (CSE) combined with abdominal hollowing (AH) on postural balance in patients with CNSLBP.
Method The present study is a double-blind clinical trial. Thirty females with CNSLBP were recruited for the clinical trial. Patients were randomly assigned to experimental and control groups (15 patients in each group). The experimental group follow up CSE combined with AH for 8 weeks. The control group did not receive any intervention. Primary outcomes included: pain (10cm visual analogue scale), disability (oswestry questionnaire), and proprioception (goniometer). Secondary outcomes included: static and dynamic balance (biodex balance system). Analysis of covariance was used to compare results and confidence interval between groups.
ResultsThe experimental group compared to the control group with a high effect size had a significant difference in reducing Pain (P= 0.021, ηp2= 0.183), disability (P= 0.007, ηp2= 0.237), and postural reconstruction error (P= 0.000, ηp2= 0.566). Also, the experimental group compared to the control group with a high effect size had a significant difference in improvement of static (P=0.008, ηp2= 0. 367) and dynamic balance (P=0.008, ηp2= 0.757).
ConclusionsThe CSE combination with AH affects three active, passive, and nervous systems. It seems that the CSE combination with AH can modify the faulty movement control in local muscles, proprioception restoration, and subsequently lead to postural stability.
