The JawClamp is a rehabilitation device designed to assist individuals with Trismus (limited opening of the mouth) or TMJ. This hand-operated clamp facilitates passive stretching of the jaw connective tissues, and is particularly useful for patients who have experienced trauma, surgery, stroke, or radiation exposure, all of which can contribute to Trismus.

The restriction in mouth opening can have severe health consequences, making it essential for patients to perform exercises that stretch the jaw muscles and improve their range of motion. Studies have demonstrated that performing passive motion exercises several times per day can effectively treat Trismus or lockjaw.
