Brief Summary
PURPOSE:The purpose of the study was to investigate the effect of mouth-opening training with follow-up telephone calls for reducing postoperative trismus in patients with oral cancer. METHODS:The study is a randomized clinical trial using repeated measures. Sixty-eight patients admitted at a general hospital in Taiwan for oral cancer surgery were recruited and randomly assigned to either the intervention or control group. All subjects were instructed to practice mouth-opening exercises three times a day every day for three months. Subjects in the intervention group received additional 6 follow-up phone calls to enhance mouth-opening exercise adherence. Data on maximum interincisal opening and mandibular function impairment were collected before surgery, at one-month, and three-months after discharge, using the TheraBite Range-of-Motion scale and Mandibular Function Impairment Questionnaire.

Outcome Measures
Primary Outcomes (1)
TheraBite Range-of-Motion Scale
The TheraBite® Range-of-Motion Scale was used to measure the maximum incisal opening (MIO), which is the maximal vertical distance between the edges of the incisors of the maxilla and the mandible. The TheraBite® Range-of-Motion Scale is a disposable paper measuring scale specially designed to measure a subject's mouth and jaw opening. The subject sits in an upright position with his mouth open wide. For measuring the vertical opening, the scale has a possible range of 5 to 70 mm, with the notch is placed on the lower incisor midline. The usual range of MIO is between 40 and 55 mm. Subjects with MIO \<35 mm are considered to have trismus.

The intervention group
EXPERIMENTALSubjects in the intervention group received two 30-minute individual trainings on the mouth-opening exercises before discharge from the hospital. Subjects were instructed to practice the mouth-opening exercises three times a day, every day, for 12 weeks. Subjects in the intervention group received additional 6 follow-up phone calls (at 1, 2, 3, 4, 8 and 12-week after discharge) from the interventionist to enhance mouth-opening exercise adherence.
The control group
ACTIVE COMPARATORSubjects in the control group also received two 30-minute individual trainings on the mouth-opening exercises before discharge from the hospital. Subjects were instructed to practice the mouth-opening exercises three times a day, every day, for 12 weeks.
Interventions
Subjects in both groups received two 30-minute individual trainings on the mouth-opening exercises before discharge from the hospital. Subjects were instructed to practice the mouth-opening exercises three times a day, every day, for 12 weeks. Subjects in the intervention group received additional 6 follow-up phone calls (at 1, 2, 3, 4, 8 and 12-week after discharge) from the interventionist to enhance mouth-opening exercise adherence.

Limitations and Caveats
Additional randomized controlled trials with longitudinal designs and larger sample sizes are needed to better define the role of the intervention in the treatment protocol for oral cancer associated trismus. Replicating this study in other settings is also recommended.
