Objectives: To compare the efficacy of acupuncture and conventional massage
for the treatment of chronic neck pain.
Design: Prospective, randomised, placebo controlled trial.
Setting: Three outpatient departments in Germany.
Participants: 177 patients aged 18-85 years with chronic neck pain.
Interventions: Patients were randomly allocated to five treatments over
three weeks with acupuncture (56), massage (60), or "sham" laser acupuncture
(61).
Main outcome measures: Primary outcome measure: maximum pain related to
motion (visual analogue scale) irrespective of direction of movement one
week after treatment. Secondary outcome measures: range of motion (3D
ultrasound real time motion analyser), pain related to movement in six
directions (visual analogue scale), pressure pain threshold (pressure
algometer), changes of spontaneous pain, motion related pain, global
complaints (seven point scale), and quality of life (SF-36). Assessments
were performed before, during, and one week and three months after
treatment. Patients' beliefs in treatment were assessed.
Results: One week after five treatments the acupuncture group showed a
significantly greater improvement in motion related pain compared with
massage (difference 24.22 (95% confidence interval 16.5 to 31.9), P=0.0052)
but not compared with sham laser (17.28 (10.0 to 24.6), P=0.327).
Differences between acupuncture and massage or sham laser were greater in
the subgroup who had had pain for longer than five years (n=75) and in
patients with myofascial pain syndrome (n=129). The acupuncture group had
the best results in most secondary outcome measures. There were no
differences in patients' beliefs in treatment.
Conclusions: Acupuncture is an effective short term treatment for patients
with chronic neck pain, but there is only limited evidence for long term
effects after five treatments.
