ClinConnect Summary

This clinical trial is looking to understand the relationship between how much patients can open their mouths and the stiffness of a muscle called the masseter, which is important for chewing. Researchers will use a special ultrasound technique to measure the elasticity, or hardness, of this muscle in patients who have recently had surgery for oral cancer. They will also include an exercise program to see if improving the muscle's stiffness can help predict how much better patients will be able to open their mouths, a condition known as trismus, which can affect eating and speaking.

To participate in this study, individuals need to be newly diagnosed with oral cancer and scheduled to receive treatments like surgery or chemotherapy, and they should be between 20 and 65 years old. However, those who cannot communicate or have other movement-related disorders will not be able to join. This trial is not yet recruiting participants, but it aims to provide valuable insights into how muscle stiffness relates to mouth opening after oral cancer treatment.
