The aim of the present study was to carry out a pilot project comparing the effectiveness of two therapeutic approaches to temporomandibular disorders (TMDs) in adolescents. Eight female individuals diagnosed based on the Research Diagnosis Criteria for TMDs (RDC/TMD-axis 1)were randomly divided into two groups: 1) Massage therapy and muscle stretching (n=4); and 2) transcutaneous electrical nerve stimulation (TENS) (n=4). Regardless the treatment, ten sessions were held for each patient and two measurements (baseline and 10th session) were performed for the assessment of symptom evolution using a visual analog scale (VAS), maximum opening of the mouth (MOM) and pressure pain threshold (PPT). Statistical analysis wiil be carefully selected.

Further study details as provided by University of Pernambuco:

Primary Outcome Measures:
  • Pain [ Time Frame: Two times a week ]
    The subjects was asked to mark the intensity of the pain on a 100mm line, which was numbered from 0 to 10, being "0" = no pain, and 10 = to the worst pain ever felt. The outcome of pain intensity was given as a number marked by the patient.

Secondary Outcome Measures:
  • Maximum mouth opening amplitude [ Time Frame: Two times a week ]
    Subjects were asked to open their mouths as much as they could and the opening amplitude was measured using a digital caliper.

Enrollment: 8
Study Start Date: April 2007
Study Completion Date: September 2007
Primary Completion Date: August 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TENS Device: Transcutaneous electrical nerve stimulation
Sensors were positioned on anterior temporal and masseter muscles bilaterally, and the stimulation was used for 20 minutes at 150 Hz and 100 µs of pulse width; intensity was adjusted individually.
Active Comparator: Massage therapy and muscle stretching Other: Physiotherapy
Massage and stretching of the anterior temporal and masseter muscle were performed by an experienced professional for 20 minutes.
