Overview

Procedural pain is inadequately managed in two-thirds of patients undergoing invasive medical procedures. Several techniques exist for managing procedural pain, but they all present implementation challenges and are not without side effects. Therefore, a new, non-pharmacological, inexpensive, and easy-to-use approach would be of significant benefit. Transcutaneous electrical nerve stimulation (TENS) for pain relief could represent this alternative. Few studies have been conducted on the benefits of TENS in managing procedural pain, for example, in shoulder arthrodistension. This project proposes to study it in the context of posterior ramus infiltration in patients eligible for this indication, in the context of chronic low back pain associated with posterior joint syndrome.
