Abstract

Background. Low back pain (LBP) is one of the most prevalent musculoskeletal conditions affecting individuals worldwide, often resulting in significant disability and reduced quality of life. As the leading cause of years lost to disability globally, the burden of LBP continues to rise alongside an aging and expanding population. Regular exercise plays a pivotal role in alleviating LBP by enhancing spinal muscle strength, improving flexibility, and optimizing posture. Interferential therapy (IFT), a transcutaneous electrical stimulation modality utilizing medium-frequency currents, is a well-established intervention for musculoskeletal disorders. This study evaluates the effectiveness of stabilization exercises using a foam roller in comparison to conventional exercise in individuals with LBP.

Methods. A total of 82 participants meeting the inclusion and exclusion criteria were randomized into two groups: a stabilization exercise group (n = 41) and a conventional exercise group (n = 41). Both groups received IFT alongside their respective exercise protocols. Each intervention session lasted 30 minutes and was administered five times per week for three weeks.

Results. Post-intervention assessments using the Modified Oswestry Disability Index (MODQ) revealed a mean score of 18.8 in the stabilization exercise group compared to 22.93 in the conventional exercise group, with a statistically significant p-value of < 0.0001. These findings demonstrate a superior reduction in pain and disability in the stabilization exercise group.

Conclusion. Stabilization exercises incorporating a foam roller provide enhanced therapeutic benefits for individuals with LBP compared to conventional exercises. The foam roller introduces an unstable surface, challenging participants and promoting greater core activation and postural control.
