Summary
Brief summary (as posted)
PURPOSE: The purpose of the study was to investigate the efficacy of mouth-opening training with follow-up on 1st、3rd、6th months for reducing postoperative trismus in patients with oral cancer. METHODS: The study is a quasi-experimental design using repeated measures. 44 patients admitted at a general hospital in Taiwan for oral cancer surgery were recruited to the control group first then 38 patients were recruited to the intervention group. All subjects were instructed to practice mouth-opening exercises three times a day every day for three months and two telephone calls fellow up. Subjects in the intervention group received mouth-opening exercise adherence. Data on maximum interincisal opening and mandibular function impairment were collected before surgery, at one month, three months, and six months after radiotherapy, using the TheraBite Range-of-Motion scale and Mandibular Function Impairment Questionnaire, Restriction of Mouth Opening Questionnaire, and Difficulty of Food Intake.
