Evaluating Immediate Effects of Electroacupuncture Versus Sham Treatment on Muscle Stiffness in Adults with Chronic Neck Pain

What this Trial Is About

Researchers are investigating the immediate effects of a single session of electroacupuncture on neck muscle stiffness in adults with chronic neck pain lasting at least 3 months. This randomized, single-blind, placebo-controlled trial aims to provide objective evidence using Shear Wave Elastography, an ultrasound-based technology, to measure muscle stiffness changes. The study addresses the limited high-quality evidence on acupunctures immediate impact on muscle biomechanics. Participants aged 18 to 65 years with non-specific chronic neck pain will be randomly assigned to one of two groups. One group will receive a 20-minute session of active electroacupuncture with electrical stimulation at specific neck and tender points, while the other group will undergo a 20-minute sham acupuncture session with non-penetrating placebo needles and a deactivated device to maintain blinding. Both procedures are administered by an experienced practitioner. During the study, muscle stiffness will be measured before and immediately after the intervention using Shear Wave Elastography. Additional assessments include pain intensity, pressure pain threshold at various muscles, and cervical range of motion. Participants will also complete a follow-up questionnaire seven days after treatment to evaluate neck function. The total participation involves a single treatment session with immediate and short-term follow-up assessments.
