Evaluation of the effectiveness of selected physiotherapeutic techniques at trigger point in myalgia form of temporomandibular disorders - randomized controlled trial

ObjectivesThe main aim of this study was to evaluate bioelectrical activity the immediate effect of the post-isometric relaxation technique (PIR) and compression technique in patients with myalgia of the masticatory muscles.Materials and Methods97 people were divided into 3 groups: the first group underwent PIR, the second group underwent trigger point compression technique, and the third group consisted of individuals without myalgia of the masticatory muscles, serving as the control group and not experiencing any therapeutic intervention.ResultsAfter the therapy, a decrease in the bioelectrical activity of the masticatory muscles and an improvement in jaw mobility were observed. These results approached those of the control group, indicating a return of the masticatory muscles to their physiological activity.ConclusionsBoth PIR therapy and trigger point compression appear to have similar therapeutic properties. Further comparative studies between these therapies are suggested to aid in treating TMDs.
