Purpose: This study aimed to investigate the effects of unstable surface-based biofeedback training on muscle activation, balance, the Oswestry disability index, and transversus abdominis performance in young adults with low back pain. Methods: Thirty young adults with low back pain were randomly assigned to either an experimental group or a control group (n=15 each). All participants performed lumbar stabilization exercises. The experimental group received unstable surface-based biofeedback training, whereas the control group received stable surface-based biofeedback training. Muscle activation, balance, the Oswestry disability index, and transversus abdominis performance were evaluated using BTS FREE EMG, PhysioSensing, and pressure biofeedback units, respectively. Within- and between-group comparisons were performed using paired t-tests and analysis of covariance, respectively. Results: Within-group analysis revealed significant improvements in both the experimental and control groups after the intervention (p<.05). Between-group analysis revealed significantly greater improvements across all outcome measures in the experimental group compared with the control group. Conclusion: These results suggest that unstable surface-based biofeedback training is an effective intervention for improving muscle activation, balance, the Oswestry disability index, and transversus abdominis performance in young adults with low back pain. Future research should investigate long-term effects of this training to optimize training programs.
