MMT Grading

Prevent substitutions and trick movements

• Stabilization

• Substitution

• Explanation and instruction

• assessment of sound limb

When muscles are weak or paralyzed, other muscles may take over or gravity may be used to perform the movements

• Stabilization

• Substitution

• Assessment of normal muscle strength

• Assess the sound limb

isolate the muscle or muscle group to be tested in either gravity elimination or against gravity position

• Substitution

• Stabilization

• Patient position

• assess sound limb
