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

Официальное название

The Value of Transcutaneous Electrical Nerve Stimulation (TENS) for Improving Pain Experienced During Posterior Branch Blocks in Patients With Lumbar Posterior Joint Syndrome: a Single-center, Randomized, Double-blind, Parallel-group, Controlled, Superiority Trial

Обзор

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.

Вмешательства

• Процедура Stimulation with TENS, which allows the release of endorphins
  Stimulation with TENS at frequencies that allow the release of endorphins before infiltration
• Процедура Stimulation with TENS does not allow the release of endorphins
  Stimulation with TENS at levels that do not allow the release of endorphins prior to infiltration
• Другое Questionnaires
  Pain questionnaires will need to be completed at the inclusion, one month and 3 months

Первичные конечные точки

• Comparison of the intensity of pain experienced during the infiltration procedure between the intervention group and the placebo group [Срок оценки: 3 months after the inclusion]

Вторичные конечные точки (3)

• Evaluation of satisfaction with the infiltration procedure in both groups [Срок оценки: 3 months after the inclusion]
• Comparison of the effectiveness of posterior branch block on pain in both groups [Срок оценки: 3 months after the inclusion]
• Assessment of pain experienced by the patient in the 2 groups [Срок оценки: 3 months after the inclusion]
