Effect of a single application of Scenar for pain relief in patients with low back and neck pain

<p class="MDPI17abstract">We aimed to demonstrate the antalgic effectiveness of ScenarTM (Self Controlled Electro Neuro Adaptative Regulation) in patients experiencing low back and neck pain. Sixty patients were included and equally assigned by randomization to a Scenar-On group and to a Scenar-Off group (sham group). All patients received a 20 minutes application of ScenarTM of the painful area. Pain at rest and at movement, and sensation of stiffness were assessed using a numeric rating scale at baseline, right after the session and 24 hours following the session. Patients' characteristics at entry were similar between groups. Pain at rest decreased after the session in both groups (from 7.5 [4.2] to 5.0 [3.5]) in the Scenar-Off group, p= 0.0001, from 6.5 [3.0] to 4.0 [4.0]) in the Scenar-On group p&lt;0.0001). Similar results were observed at mobilization but sensation of stiffness was not modified. Such beneficial results do not last until the next day. No undesirables major  effects were noticed. Our study does not support the fact that one Scenar session improves better low back and neck pain than a sham session.</p>
