The Potential of Transcutaneous Electrical Nerve Stimulation to Improve Pain Experienced During Posterior Branch Blocks in Patients With Lumbar Posterior Joint Syndrome

Procedural pain is inadequately managed in two‐thirds of patients undergoing invasivemedical procedures. Several techniques exist for managing procedural pain, but they allpresent implementation challenges and are not without side effects. Therefore, a new,non‐pharmacological, inexpensive, and easy‐to‐use approach would be of significantbenefit. Transcutaneous electrical nerve stimulation (TENS) for pain relief couldrepresent this alternative. Few studies have been conducted on the benefits of TENS inmanaging procedural pain, for example, in shoulder arthrodistension. This projectproposes to study it in the context of posterior ramus infiltration in patients eligiblefor this indication, in the context of chronic low back pain associated with posteriorjoint syndrome.
