Exploring EMG Biofeedback in Core Training - Bosu Ball vs Swiss Ball Efficacy for Collegiate Students with Mechanical Low Back Pain: A Randomized Controlled Trial.

Purpose: Given the high prevalence of low back pain in this demographic group, effective management strategies are essential. This study aimed to compare the effects of EMG biofeedback-assisted core training using Bosu versus Swiss balls on mechanical low back pain in collegiate students. Methods: A randomized controlled trial was implemented with 36 participants aged 18-25, randomly assigned to either the Bosu or Swiss ball group. Over four weeks, both groups engaged in specific core strengthening exercises three times a week. Pain intensity, core strength, and functional ability were assessed using the Numeric Pain Rating Scale, Oswestry Disability Index, and EMG analysis, respectively. Results: Both groups demonstrated significant improvements in pain, functional disability, core strength, and muscle activation following the intervention (p < 0.05). No statistically significant differences were observed between the Bosu ball and Swiss ball groups in the primary outcome measures, however, some enhancements were noted in range of motion, muscle activation and functional disability in the Bosu ball group. Conclusion: EMG biofeedback-assisted core training with Bosu balls is more effective than Swiss balls in managing mechanical low back pain in collegiate students. These findings suggest that incorporating Bosu ball exercises can enhance therapeutic outcomes, underscoring the need for tailored rehabilitation strategies to improve quality of life for young adults suffering from low back pain.
