Manual Muscle Testing Grades

Vocabulary flashcards defining each grade in the Manual Muscle Testing (MMT) scale.

Normal ($5/5$)

The subject completes ROM against gravity with maximal resistance

Good Plus ($4+/5$)

The subject completes ROM against gravity with moderate-maximal resistance

Good ($4/5$)

The subject completes ROM against gravity with moderate resistance

Good Minus ($4-/5$)

The subject completes ROM against gravity with minimal-moderate resistance

Fair Plus ($3+/5$)

The subject completes ROM against gravity with only minimal resistance

Fair ($3/5$)

The subject completes ROM against gravity without manual resistance

Fair Minus ($3-/5$)

The subject does not complete the ROM against gravity, but does complete more than half of the range

Poor Plus ($2+/5$)

The subject is able to initiate movement against gravity

Poor ($2/5$)

The subject completes ROM in a gravity-eliminated position

Poor Minus ($2-/5$)

The subject does not complete ROM in a gravity-eliminated position

Trace ($1/5$)

The subject's muscle contraction can be palpated, but there is no joint movement

Zero ($0/5$)

The subject demonstrates no palpable muscle contraction
