To evaluate the effectiveness of quadratus lumborum muscle stretching exercises in reducing mechanical low back pain among the young and middle-aged population of Haryana.

This study explored the effectiveness of passive stretching of the quadratus lumborum (QL) muscle in individuals with mechanical low back pain (MLBP). Through six treatment sessions over 21 days, significant improvements were observed in back pain distribution. This study contributes valuable insights into addressing MLBP and advocates for the inclusion of QL stretching in clinical practice.Healthcare professionals commonly encounter low back pain, a widespread condition affecting individuals across all age groups and believed to be a leading cause of disability worldwide, in both developed and developing countries. While males are generally less affected than females, approximately 80% of patients report experiencing moderate to severe pain that significantly disrupts their daily routines. Quadratus lumborum muscle is already being used separately in different conditions, So there is a need to investigate the effectiveness of QL muscle for improving ADLS and reducing pain in patients with mechanical low back pain. The results suggest that QL stretching can reduce MLBP and enhance daily functioning. The findings underscore the importance of integrating QL stretching into physiotherapy protocols for MLBP management, offering a cost-effective and accessible treatment option.
