About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Chronic low back pain (lasting more than 3 months)

Patient followed in a Chronic Pain Unit (CETD, Toulouse University Hospital)

Clinical and radiological diagnosis (CT scan or MRI) of posterior joint syndrome

Patient with an indication for infiltration therapy, feasible under standard conditions

Disqualifiers

Spinal surgery

Wearing an electronic medical device (pacemakers, defibrillators, etc.)

Pregnancy

Area of cutaneous anesthesia

Trial design

Design model

Parallel

Treatments tested in this trial

  • Stimulation with TENS, which allows the release of endorphins

    Procedure/Surgery

    Stimulation with TENS at frequencies that allow the release of endorphins before infiltration

  • Stimulation with TENS does not allow the release of endorphins

    Procedure/Surgery

    Stimulation with TENS at levels that do not allow the release of endorphins prior to infiltration

  • Questionnaires

    Other intervention

    Pain questionnaires will need to be completed at the inclusion, one month and 3 months

Treatment groups

52 Participants
are divided into 2 treatment groups
Group A: Interventional group with TENS in gate control modeExperimental treatment 2 interventions
Group B: Control group using TENS with placebo stimulationActive comparator 2 interventions
