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.

Conditions

  • Oral Cancer

Interventions

BEHAVIORAL

The mouth-opening training with follow-up telephone calls program

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.

BEHAVIORAL

The mouth-opening training without follow-up telephone calls program

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.
