Background:
Hypnorelaxation has a potentially beneficial effect in the treatment of masticatory myofascial pain disorders (MPD). However, there are no data regarding the efficacy of hypnorelaxation in the treatment of MPD compared with other accepted modes of treatment (such as occlusal appliance) or with the mere effect of time.
Objective And Subjects:
The purpose of the present study was to evaluate the effectiveness of hypnorelaxation in the treatment of MPD compared with the use of occlusal appliance and/or to minimal treatment. The study population consisted of 40 female patients with myofascial pain who were allocated to 1 of 3 possible treatment groups: (1) hypnorelaxation (n = 15), (2) occlusal appliance (n = 15), and (3) minimal treatment group (n = 10).
Results:
Both active treatment modes (hypnorelaxation and occlusal appliance) were more effective than minimal treatment regarding alleviating muscular sensitivity to palpation. However, only hypnorelaxation (but not occlusal appliance) was significantly more effective than minimal treatment with regard to the patient's subjective report of pain on the Visual Analog Scale.
Conclusion:
Hypnorelaxation is an effective mode of treatment in MPD, especially with regard to some of the subjective pain parameters.
