Modified medical research council manual muscle testing scale. Florence et al, 1992 [12].

mMRC-MMT scale grades	Description
0	No Movement
1	A flicker of movement is seen or felt in the muscle
2	Muscle moves the joint when gravity is eliminated
3−	Muscle moves the joint against gravity but not through full mechanical range of motion
3	Muscle cannot hold the joint against resistance but moved the joint fully against gravity
3+	Muscle moves the joint fully against gravity and is capable of transient resistance but collapses abruptly
4−	The same as grade 4, but muscle holds the joint only against minimal resistance
4	Muscle holds the joint against a combination of gravity and moderate resistance
4+	The same as grade 4, but muscle holds the joints against moderate to maximal resistance
5−	Barely detectable weakness
5	Normal strength
