Testing Weakness vs Inhibition

Many clinicians doing manual muscle test may mistake motor pattern inhibition for true weakness. How do you tell the difference? If someone tests weak, try applying very light resistance and slowly increase. If the pattern/muscle test significantly increases as you gradually increase resistance, the muscles are not weak, the pattern is inhibited.

interesting take on this. I'm a little confused though about what we, as therapists, would see in each scenario. From what I took away, your saying that a slower, more progressive increase in external load will drop off predictably in a case of weakness, and will remain strong or behave unexpectedly when the muscle is inhibited. did I get that right?

Will Harvey yes. If it's inhibited as you increase manual resistance their amount of ability to resist will also proportionately increase. If it's true weakness it will test weak and they'll be unable to resist past a certain point. In MMT terms I'm saying start with a grade 2 and slowly progress to 5/5 break test

Awesome -- thanks! Interesting concept to explore, and a fun/time-consuming rabbit hole to dig into the possible reasons driving the weakness/inhibition.

Will Harvey try it on the expected weak areas like mid and lower trap or glut med and see what happens. May indicate Manual techniques to reset the system

it sounds interesting indeed! Please could u explain in little more detail if ur referring to a neuromuscular inhibition specifically or just guarding a muscle during injury or inflammation? it would also help to know on a physiological level about why a mm fibre behaves differently in the 2 situations to progressive load.

We don't know exactly why muscles behave that way. In the presence of perception of threat, there is an output of pain and alteration of neuromuscular control, and usually increased tone. There doesn't need to be injury or inflammation, just perception of threat.
