Effectiveness of Lumbar Segmental Stabilization Exercises in Managing Disability and Pain Intensity Among Patients With Lumbar Spondylolysis and Spondylolisthesis

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: This study aims to assess the effectiveness of lumbar segmental stabilization exercise (LSSE) in managing spondylolysis and spondylolisthesis. SUMMARY OF BACKGROUND DATA: Spondylolysis and spondylolisthesis are spinal disorders associated with lumbar segmental instability. LSSE has shown positive effects in treating these conditions; however, systematic reviews and meta-analyses are lacking. MATERIALS AND METHODS: A systematic search adhering to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, including studies from the inception of the databases used up to January 2024, was conducted. Disability improvement and pain intensity change were the primary and secondary outcomes, respectively, standardized using Hedges g . Eligible articles underwent independent scrutiny by two authors, who also performed data extraction and quality assessment. Data pooling was accomplished using a random-effects model. RESULTS: In total, five randomized controlled trials comprising 198 participants were included, revealing a trend effect toward disability improvement in the LSSE group (Hedges g =-0.598, 95% CI: -1.211 to 0.016, P =0.056, I2 =75.447%). When the LSSE was administered as a single treatment, disability improvement became significant (Hedge g =-1.325, 95% CI: -2.598 to -0.053, P =0.041, I2 =80.020%). No significant effect of LSSE on pain reduction was observed (Hedges g =-0.496, 95% CI: -1.082 to 0.090, P =0.097, I2 =73.935%). CONCLUSIONS: In summary, our meta-analysis suggests that LSSE can potentially improve disability, especially when used as a single treatment. LSSE appears more beneficial in reducing disability than alleviating pain. Future research on different patient groups is needed to understand comprehensively LSSE's effects on other musculoskeletal disorders.
