The goal of this clinical trial is to determine whether acupuncture can improve neck pain and shoulder movement in people with chronic neck pain. Researchers will compare acupuncture with sham acupuncture (a procedure designed to resemble acupuncture without therapeutic effects) to determine whether acupuncture provides specific benefits.
Participants will be randomly assigned to receive either acupuncture or sham acupuncture. They will attend 1 treatment session and undergo assessments of neck and shoulder movement, muscle activity, pain intensity, and neck-related disability before and after treatment. Researchers will also monitor any adverse events associated with treatment.
