Transcutaneous nerve stimulation in a group of patients with rheumatic disease involving the temporomandibular joint.

The effect of transcutaneous nerve stimulation (TNS) was evaluated and compared with placebo TNS in 19 patients (17 women, mean age 33 years) with orofacial functional pain and rheumatic disease involving the temporomandibular joint. In two double-blind noncrossover experiments, high frequency TNS (100 Hz) and low frequency TNS (2 Hz) were evaluated by comparison of the patients' functional and rest pain, muscle and joint tenderness, and jaw function. A significant treatment effect was obtained for all treatment methods regarding functional and rest pain and muscle and joint tenderness. None of the parameters except functional pain, which improved significantly more after high frequency TNS than placebo TNS, revealed any difference between the methods. Jaw function, however, revealed a few differences between high frequency TNS and placebo TNS.
