Which grade on the MMT scale is described as 'Partial ROM in gravity eliminated position' (2-)?

• A. 2
• B. 3
• C. 2-
• D. 1

Answer: (C)

In manual muscle testing, the grading system reflects how much movement a muscle can produce and whether gravity affects that movement. Testing in a gravity-eliminated position removes the effect of gravity so you can see how much ROM is truly available.

Partial ROM in gravity-eliminated position means the person can move the joint but not through the full available ROM when gravity isn’t aiding the movement. That specific description matches the grade two minus. It’s weaker than moving through full ROM in gravity eliminated (grade two) and much weaker than moving through ROM against gravity (grade three). It’s also above a mere trace contraction (grade one) and no contraction (grade zero).

So the grade described is two minus.
