I must have overlooked this one or just was not paying attention. While I thought initially, who needs a calculator for MMT? It’s pretty straightforward, right? Thinking back, it wasn’t so easy for me to learn either.
It takes some time to wrap your head around the gravity eliminated, the 50%’s, and the plus/minuses. Then there are different terms and fractions to keep track of. While some people may be able to learn MMT from looking at the chart and its definitions, I decided to make a flow/chart that asks you a question starting from 0/5, zero and ending at 5/5, normal. This thought process might help some of you learn MMT in another way if just starting at a chart is not working out.
Click around with the calculator selections and see how it calculates the corresponding answer. When you can guess the answer fairly quickly for different scenarios, then you probably have it learned.
The next step is to be really fast with coming up with the answer with a simulated patient and no calculator. You should be able to measure a MMT at a joint and be able to come up with a score within a few seconds, not a minute. It takes time and practice. Practice easier joints such as elbow flexion/extension repeatedly until you get the scale down, then progress to more difficult joints that involve different planes of movement for gravity eliminated and against gravity motions, e.g., shoulder internal/external rotation is gravity eliminated while seated in the standard testing position and to be against gravity, it will require that the patient lies on their side.
Last tip: practice with an OT classmate or with a friend or loved one. Have them try to be each different MMT and have you guess what they were intending to be.
