Brief Summary

Trismus (limited jaw mobility), can occur in patients undergoing radiotherapy to specific areas of the head or neck. Trismus leads to difficulty in eating, swallowing, speech and general mouth hygiene, which all have negative effects on quality of life. Research in the area of trismus is limited; it is not known exactly when trismus develops, one study suggests that some patients have experienced a diminished opening at as low doses as 15 Gy. Literature suggests benefits of a training programme, but there is a lack of evidence to support the use of a training programme during radiotherapy. The purpose of this study is to investigate the effectiveness of a training programme during and after radiotherapy, and report the incidence of trismus in patients who receive radiotherapy to the jaw muscles. The study also investigates quality of life during radiotherapy and up to one year after completed treatment. Patients who meet the criteria and give their consensus to the study are divided into two groups: Group 1: Training with TheraBite Jaw Motion Rehabilitation System, which is a portable system utilizing repetitive passive motion and stretching to restore mobility and flexibility of the jaw musculature. Individuals train five times a day. Group 2: Conventional treatment (jaw measurements once a week). If the individuals jaw mobility decreases 15% from the original start measurement, the patient is automatically offered a trainings program (as in group 1). During radiation therapy a hospital specialist dentist measures the jaw mobility once a week, thereafter at 3,6,12 months after completed Radiation Therapy. On 5 different occasions the patients are requested to complete a Quality of life questionnaire. Patient's record their training frequency in a log book.

Outcome Measures

Primary Outcomes (1)

  • Change in Jaw mobility measurement during Radiotherapy

    Proportion of participants free from trismus at the end of Radiotherapy.

    Up to 7 weeks

Secondary Outcomes (1)

  • Change in Jaw Mobility measurement at 6 and 12 months after completed Radiotherapy

    6 and 12 months

Study Arms (2)

TheraBite grupp

EXPERIMENTAL
Device: TheraBite® Jaw Motion Rehabilitation System™

Conventional treatment

NO INTERVENTION

Interventions

A portable device which utilizes passive motion and stretching to improve mobility and flexibility of the jaw muscles and associated joints. Patients are given written and verbal information about TheraBite before the commencement of Radiotherapy. Investigators instruct on usage and maintenance of TheraBite. Patients are instructed to start a trainings pass by softening the jaw muscles with a simple exercise. The training programme consists of five stretches performed 5 times per day, each stretch held for 15 seconds, training continually during Radiation Therapy and up to one year after completion of Radiation Therapy.
