Summary

The aim of the present study was to investigate the effect of photobiomodulation (PBM) and manual therapy (MT) isolated or combined in the reduce of pain, the improve of mandibular movements, the psychosocial aspects and the anxiety symptoms of patients with TMD.

Detailed description

Temporomandibular disorders (TMD) is a complex and multifactorial disease. Therapeutic modalities, as PBM and MT, expected to relief of symptoms, improve of function and reduce the impact of the disease in patient's life. Fifty-one TMD patients were randomly allocated to three groups: PBM group (n=18) using 808 nm, 100 milliwatt (mW), 13.3 J ∕cm2, 4 J per point), MT group (n=16) with 21 minutes sessions of MT of the masticatory muscles and TMJ and Combined Therapy group (CT) (n=17) applying the 2 protocol described above. All treatments were done three times a week for four consecutive weeks. Evaluations were performed at baseline, during the treatment (days 7, 14, 21, and 28) and follow up (day 60 and day 90). Visual analogue scale (VAS), Research Diagnostic Criteria (RDC/TMD) Axis I and II, Beck anxiety inventory (BAI) were used in different moments of evaluation time.

Conditions

• Temporomandibular Disorder

Interventions

Type	Name	Description
PROCEDURE	Photobiomodulation	PBM was applied, three times a week for four consecutive weeks at 5 points in the TMJ region: superior, anterior, lateral, posterior and postero inferior to the condyle. In addition, all patients received laser application in the temporal muscle (anterior, middle and posterior), in the masseter (upper, middle and lower portion) and insertion of the medial pterygoid.
PROCEDURE	Manual Therapy (MT)	Patients were submitted to MT at temporal, masseter and pterygoid medial from both sides, during 3 minutes each muscle group (Extraoral) and at masseter and lateral pterygoid (Intraoral) for 3 minutes, each total 21 minutes. MT on the TMJ region was performed for 1 minute and 3 repetitions during three times a week .
