Smith P, et al. School of Dentistry, The University of Manchester,
Higher Cambridge Street, Manchester M15 6FH, United Kingdom.
RESULTS: The results demonstrated that real acupuncture had a greater influence on clinical
outcome measure of TMJ MP than those of sham acupuncture, and the
majority of these reached a level of statistical significance.
METHODS: A double blind randomised controlled trial conducted in the TMD
Clinic, at the School of Dentistry, The University of Manchester.
Twenty-seven patients were assigned to one of two treatment groups.
Group 1 received real acupuncture treatment whilst Group 2 received a
sham acupuncture intervention. Both the assessor and the patient were
blinded regarding the group allocation. Baseline assessment of the
outcome variables was made prior to the first treatment session, and
was repeated following the last treatment.
CONCLUSION: Acupuncture had a positive influence on the signs and
symptoms of TMJ MP. In addition, this study provides evidence that the
Park Sham Device was a credible acupuncture control method for trials
involving facial acupoints.
