Hypnorelaxation as treatment for myofascial pain disorder: a comparative study.

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.

Experimental chewing in myofascial pain patients.

Aims: To evaluate the potential capacity of a chewing exercise to differentiate chronic myofascial pain (MFP) patients from healthy controls and to test whether there are distinct pain response differences among MFP patients.

Methods: Eighty-nine subjects participated in the study; 49 were diagnosed as belonging to the MFP subgroup of temporomandibular disorders (TMD) and had suffered from MFP for at least 6 months, and 40 healthy age- and gender-matched subjects comprised the control group. After completion of a clinical examination, all subjects performed a chewing exercise.
