Acupuncture in the treatment of chronic cervical pain. A pilot study.

Thirteen patients with neck pain of at least two years' duration participated in the study. Patients were randomly assigned to either an acupuncture group or a placebo TNS (transcutaneous nerve stimulation) group. Initial pain scores revealed no significant difference between the groups with respect to pain severity. Patients were treated twice weekly for four weeks, at the end of which pain relief was measured using a simple descriptive scale. Even though an attempt was made to maximize the effect of placebo TNS using strong verbal suggestion, acupuncture still proved superior to placebo in the relief of cervical pain (p less than 0.01). The implications of these findings are discussed.
