Effects of Dynamic Neuromuscular Stabilization/Vojta Therapy on Pain Intensity and Physical Function in Individuals with Low Back Pain: A Systematic Review and Meta-Analysis.

Background: Low back pain (LBP) is a prevalent health issue that imposes heavy burdens on personal health status and social healthcare. Dynamic Neuromuscular Stabilization (DNS)/Vojta therapy has demonstrated effectiveness in managing conditions related to musculoskeletal system. However, its effects on individuals with LBP remain incompletely understood. We aimed to evaluate the effects of DNS/Vojta therapy on pain intensity and physical function in individuals with LBP.

Methods: A search of studies was conducted on several academic databases from inception through April 13, 2023. This study included clinical trials that evaluated the effects of DNS/Vojta therapy on the outcomes in individuals with LBP. The methodological quality of studies was assessed using PEDro scale, Cochrane Collaboration tool, and ROBINS-I scale. Meta-analysis was performed using Review Manager software (RevMan version 5.4.1, The Cochrane Collaboration, 2020).

Results: This systematic review and meta-analysis identified twelve eligible studies, which demonstrated that DNS/Vojta therapy significantly alleviated pain intensity (SMD=-1.09; 95%Cl [-1.74, -0.44]; Z=3.28; P=0.001), reduced disability severity (SMD=-0.91; 95%Cl [-1.48, -0.34]; Z=3.12; P=0.002), and improved quality of life (SMD=1.05; 95%CI [0.14, 1.96]; Z=2.27; P=0.02) in individuals with LBP, while no significant improvements were observed in static and dynamic balance ability or spine flexibility.

Conclusion: DNS/Vojta therapy is a promising approach for providing great benefits for individuals with LBP, particularly in terms of reducing pain intensity and disability severity, and improving quality of life, which is worth further in clinical application.
