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.

| Transcutaneous electrical nerve stimulation | Device | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Pain | 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. | Two times a week |
| Measure | Description | Time Frame |
|---|---|---|
| Maximum mouth opening amplitude | Subjects were asked to open their mouths as much as they could and the opening amplitude was measured using a digital caliper. | Two times a week |
