Active SCENAR device therapySham SCENAR device Therapy
Active SCENAR device therapy: The session consists of applying the SCENAR device to the neck and surrounding cervical muscles.The device will be moved over the painful cervical area, with intensity adjusted according to patient feedback, in non-invasive sessions typically lasting 20 minutes.
Sham SCENAR device Therapy: The SCENAR device will be applied to the painful cervical area without deliver electrical impulses.
Study summary
Shifting away from a medication-centered approach is a major public health priority, particularly in chronic pain management, where non-pharmacological therapies are recommended despite barriers such as limited evidence and low prescriber awareness.
SCENAR (Self-Controlled Energo-Neuro Adaptive Regulation), an electrotherapy device, lacks robust randomized controlled trial data. A prior study showed effects in both active and placebo groups after a single session, supporting further investigation.
This study aims to assess whether repeated SCENAR sessions improve disability, mobility, and pain in patients with chronic neck pain.

Primary outcome measure(s)
Change from baseline in Neck Disability Index (NDI) score — Baseline and 2 weeks after the last SCENAR session (approximately 10 weeks after baseline) Change from baseline in the Neck Disability Index (NDI) score, assessed using the Neck Disability Index questionnaire. The NDI score is expressed as a percentage from 0% to 100%, with higher scores indicating greater neck-related disability.
