MMT Basics and Principles 2

Question 1

In MMT, what does a grade of '3' (Fair) indicate about a muscle?

Accepted Answer

Full ROM against gravity with no additional resistance

Answer

Grade 3 (Fair) means the muscle can move the limb through full range of motion against gravity but cannot tolerate any additional resistance.

Question 2

Which plane of testing is used when gravity is eliminated during MMT?

Accepted Answer

Horizontal plane

Answer

When gravity is eliminated, the limb is moved in the horizontal (gravity-minimized) plane so gravity does not resist or assist the motion.

Question 3

What is the primary purpose of stabilization during an MMT?

Accepted Answer

To prevent substitution by other muscles

Answer

Stabilization prevents substitution movements by fixing proximal segments so only the target muscle group performs the motion.

Question 4

A muscle graded '1' (Trace) on the Kendall scale demonstrates which finding?

Accepted Answer

Visible or palpable contraction but no joint motion

Answer

Grade 1 (Trace) indicates a visible or palpable muscle contraction that is insufficient to produce any joint movement.

Question 5

Which MMT grade is considered the threshold for functional antigravity strength?

Accepted Answer

Grade 3

Answer

Grade 3 (Fair) is the minimum grade at which a muscle can move a body segment against gravity through full ROM, marking functional antigravity capacity.
