This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether catching jaw stiffness early and starting physical therapy right away can help people treated for head and neck cancer. Jaw stiffness, called trismus, is a common side effect where your mouth opening becomes limited. The study will monitor your mouth opening weekly during and after radiation treatment, and if it starts to decrease, you'll receive physical therapy with exercises, manual therapy, and use of a jaw stretching device.
Many people treated with radiation for head and neck cancer develop jaw stiffness that affects eating, speaking, and quality of life. Right now, doctors don't have clear guidelines on when and how to use physical therapy to prevent this problem, so this study is designed to figure out the best approach.

If you join the surveillance group, you'll have your mouth opening measured weekly during your radiation treatment and for some time after. If your mouth opening decreases by more than 5% or falls below 35 millimeters, you'll start a physical therapy program that includes jaw and neck exercises, manual therapy from a therapist, and practice with a jaw stretching device at home. The study will help researchers understand how to best prevent and manage jaw stiffness in head and neck cancer survivors.
