Abstract
BACKGROUND:Trismus after head and neck cancer is a symptom associated with pain and negatively affected health-related quality of life. The purpose of this study was to compare two different jaw exercise devices and the compliance to exercise. METHODS:Fifty patients with head and neck cancer were randomized to jaw exercise with either the TheraBite or Engström jaw device in a 10-week exercise program. Patients were regularly assessed by an oral surgeon, filled in exercise diaries, and answered the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 Head and Neck 35-questions (EORTC QLQ H&N35) and the Gothenburg Trismus Questionnaire (GTQ). RESULTS: Both groups improved their mouth opening, 7.2 mm (22.9%) and 5.5 mm (17.6%) for TheraBite and Engström, respectively. The largest increase in mouth opening and highest compliance to exercise was seen during the 4 first weeks. CONCLUSION:Jaw exercise therapy effectively improved mouth opening capacity and led to less trismus-related symptoms. Both jaw devices were proved efficient and compliance to exercise was comparable.
