Comparing Dry Needling and Soft Tissue Mobilization for Hamstring Tightness in Adults with Chronic Low Back Pain

What this Trial Is About

Researchers are evaluating the effects of dry needling versus soft tissue mobilization on hamstring tightness in patients with chronic low back pain. Chronic low back pain is defined as pain lasting 12 weeks or longer, and hamstring tightness is described as difficulty extending the knee beyond 160 degrees while the hip is flexed at 90 degrees. This randomized clinical trial aims to assess how these treatments impact pain, range of motion, and functionality. The study will include 30 participants divided into two groups of 15 each. Both groups will receive baseline treatments including hot packs applied for 15 minutes on the hamstrings and lower back, transcutaneous electrical nerve stimulation TENS for warm-up and pain relief, and spinal mobilization with posterior anterior glide techniques. Group A will receive dry needling on three specific points of the hamstring muscle, performed twice a week for four weeks, totaling eight sessions. Group B will receive soft tissue mobilization using the Graston technique, also twice weekly for four weeks. Participants will undergo assessments at four weeks, including the Numeric Pain Rating Scale to measure pain, the Oswestry Disability Index to evaluate disability, inclinometer measurements, and the Active Knee Extension Test. These evaluations will help determine changes in pain levels, range of motion, and functional ability. The study will monitor participants throughout the treatment period, with no mention of long-term follow-up beyond the four weeks of treatment.
