Jaw Opening—Measuring MIO MJO

Описание: n this video, we’ll walk step by step through how to measure maximal interincisal opening (MIO) and maximal jaw opening (MJO). These measurements are essential when monitoring jaw mobility, especially for people recovering from head and neck cancer treatment, radiation therapy, or surgery.

You’ll learn:
-How to correctly measure MIO using a simple tape measure
What to do if your patient does not have upper teeth
What to do if your patient does not have lower teeth
Adjustments you can make for accuracy with or without dentition
How this measurement helps track trismus progress and therapy goals


Accurate measurement ensures you can monitor changes, create effective therapy plans, and track progress with tools like the ARK-J Wedge Trismus Stretching Device, designed for safe and gradual stretching.
