Optimal electrode positioning for transcutaneous electrical nerve stimulation (TENS) therapy targeting lateral epicondylitis involves placing electrodes around the affected area. Typically, one electrode is placed over the point of maximal tenderness on the outer elbow, while the other is placed a few centimeters away, either proximally or distally along the forearm muscles. Alternative placements may involve positioning electrodes around the common extensor tendon origin or along the muscle bellies of the forearm extensors.
This precise placement helps deliver targeted electrical impulses to the affected nerves and muscles, potentially offering pain relief and promoting healing. TENS therapy has been used for decades in the management of musculoskeletal pain and its application for lateral epicondylitis provides a non-invasive option for managing discomfort and potentially improving function. The modality’s effectiveness is believed to stem from the modulation of pain signals and potential stimulation of endorphin release.
