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.
