Dynamic stretching of tensor fascia lata and its impact on lumbopelvic rhythm in individuals with chronic low back pain

Abstract

Low back pain (LBP) is a prevalent global health issue with significant implications for individuals' daily lives. Although the cause of LBP remains unclear, changes in lumbopelvic structures due to musculoskeletal issues are considered a key factor. Chronic LBP, persisting beyond three months, is influenced by individual and psychological factors. Muscles around the spine, including the tensor fascia lata (TFL), play a crucial role in maintaining spinal stability and joint functions. Prolonged shortening of the TFL can lead to an anterior pelvic tilt and abnormal spine alignment, causing pain in the lumbar and pelvic regions. Stretching this muscle is essential to alleviate low back pain by enhancing hip and pelvic range of motion. Trunk movement, occurring within the sagittal plane, is influenced by the lumbar spine and pelvic region. The evaluation of lumbopelvic rhythm (LPR) in trunk movement has been extensively investigated, suggesting that changes in LPR may indicate modifications in neuromuscular control of trunk movement. Exercises, particularly stretching exercises, play a crucial role in LBP treatment, with dynamic stretching of the TFL showing potential benefits. Studies on dynamic stretching indicate improvements in joint range of motion, muscle strength, power, and sprint time. However, the specific impact of dynamic stretching targeting the TFL on lumbopelvic movement patterns in individuals with LBP remains unknown. The authors suggest that dynamic stretching of the TFL may provide pain relief, increase range of motion, and positively impact the ability of LBP sufferers to resume their regular lives.
