Please be advised that due to the high volume of submissions, the ANZCTR is currently experiencing delays in processing submissions from those outside of Australia and New Zealand. As the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first, therefore international submissions should allow additional time for registration or updates to registration records.

Interventional
Description of intervention(s) / exposure
The acupuncture therapy was performed twice a week, with an average of 30 minutes for five uninterrupted weeks in individuals with temporomandibular disorders. The subjects were evaluated before, immediately after and after 10 sessions by surface electromyography of the masticatory muscles. The temporomandibular acupuncture points of needling were ST5, ST7, TH17, Taiyang, , Yntang, LI4 and GB43, placed in the subject's face, hands and foot.
