Research has indicated that a diversity of physical (e.g., drugs, bite-plate) and psychological (e.g., biofeedback, individual and group psychotherapy) interventions will alleviate the symptoms of myofascial pain dysfunction (MPD) syndrome in 70 to 80% of patients. The purpose of the present study was to evaluate the effects of two relaxation training methods that are less costly and have fewer side effects than other methods, and to compare these with a previously reported realistic placebo method. The results indicated that both relaxation training methods produced about equivalent effects. Both were more effective than the realistic placebo method, while at the same time having several apparent advantages over other methods in terms of cost, side-effects, and generalization and maintenance of treatment effects.
