Summary

The combination of ultrasound and muscular stretching may have positive effects on pain relief and on the balance of the masticatory muscles activity.

Detailed description

This study aimed to evaluate the therapeutic response of ultrasound (US) and ultrasound associated with stretching of the masticatory muscles on the pressure pain threshold and the electrical activity of masseter and anterior temporal muscles in Temporomandibular Disorder (TMD) patients . The study included 18 women with TMD diagnosed by the instrument Research Diagnostic Criteria for Temporomandibular Disorders (RDC / TMD). The pressure pain threshold, evaluated through algometry, and the electrical activity of the masticatory muscles were evaluated, by means of surface electromyography, before and immediately after the therapeutic procedures. The volunteers underwent three different interventions: ultrasound, ultrasound associated with stretching and ultrasound placebo, with a 1-week of minimum interval between them.

Conditions

• Temporomandibular Joint Disorders

Interventions

Type	Name	Description
OTHER	Ultrasound	3 MHz ultrasound in continuous mode with an intensity of 1.0 W / cm ² was applied for 3 minutes in the TMJ and masseter muscles bilaterally
OTHER	Ultrasound associated with stretching	3 MHz ultrasound in continuous mode with an intensity of 1.0 W / cm ² was applied for 3 minutes in the TMJ and masseter muscles, bilaterally. Active stretching of the masseter muscles with mouth opening and closed lips
OTHER	Placebo	Turned off ultrasound application on area of TMJ and masseter muscle, bilaterally.
