About

This randomized controlled trial aims to evaluate the combined effects of post-isometric relaxation and myofascial release on pain, flexibility, and functional disability in individuals with low back pain associated with lower cross syndrome. Eligible participants aged 18 to 45 years will be randomly allocated into two parallel intervention groups. One group will receive post-isometric relaxation combined with myofascial release, while the comparison group will receive conventional stretching combined with Therapeutic modalities. Outcomes will be assessed at baseline and after completion of the intervention period. The results of this study are expected to contribute to evidence-based physiotherapy management of low back pain associated with postural imbalance.
