Brief summary (from the registry)
The goal of this clinical trial is to determine whether a combination of passive and active hamstring stretching (PAS) is more effective than passive stretching alone (PS) in improving flexibility in patients with chronic low back pain (CLBP). The main questions it aims to answer are: Does PAS lead to greater improvements in active flexibility compared to PS? Does PAS provide additional benefits in passive flexibility, hamstring stiffness, and pelvic tilt? Researchers will compare the PAS group and the PS group to see if combining passive and active stretching results in greater improvements in flexibility and movement control. Participants will: Perform either PAS or PS stretching exercises as assigned. Undergo measurements of flexibility, hamstring stiffness, and pelvic tilt before and after the intervention. Answer a question about their perceived change in flexibility following the intervention. This study aims to improve rehabilitation strategies for people with CLBP, helping them achieve better movement and pain relief.
