Transcutaneous electrical nerve stimulation (TENS) is a non-invasive, safe, and widely used modality for pain reduction, but its very short-term (immediate) effects on lumbar muscle stiffness have not been clearly demonstrated. This randomized controlled trial will compare a single 20-minute session of conventional TENS with a control\u002Frest condition in patients with non-specific low back pain. The primary outcomes will be change in lumbar erector spinae muscle stiffness (Myoton) and change in pain intensity (VAS) from baseline to immediately after the intervention. We hypothesize that TENS will produce a greater immediate reduction in muscle stiffness and pain than control.",[29,30,31],"Low Back Pain","Non-specific Low Back Pain","Lumbar Muscle Stiffness",[33,29,34,35],"TENS","Muscle Stiffness","Randomized Controlled Trial","NOT_YET_RECRUITING","2025-11-17",{"date":39,"type":40},"2025-11-21","ACTUAL",{"date":42,"type":23},"2025-11-25",{"date":44,"type":23},"2025-12-01",{"name":46,"class":47},"Erzurum Technical University","OTHER"]
