MUSCLE GRADING CHART

Results may be reported using a verbal scale or a percentage loss of muscle strength as follows. In either case, the evaluator must still describe how a given loss of muscle strength affects the injured worker's capacity to perform work.


MUSCLE GRADATION DESCRIPTION
5-Normal 5-complete range of motion against gravity withfull resistance
4-Good 4-complete range of motion against gravity withsome resistance
3-Fair 3-complete range of motion against gravity
2-Poor 2-complete range of motion with gravity eliminated
1-Trace 1-reads evidence of slight contractility, no joint motion
0 (Zero) 0-no evidence of contractility

KENDALL LOVETT DESCRIPTION
100 %95 % NormalNormal - The ability to hold the test position against gravity and maximum pressure, or the ability to move the part into test position and hold against gravity and maximum pressure
90 %80 %_ Good +Good Same as above except holding against moderate pressure.
70 %60 % Good -Fair + Same as above except holding against minimum pressure.
50 % Fair The ability to hold the test position against gravity, or the ability to move the part into test position and hold against gravity.
40 % Fair - The gradual release from test position against gravity; or the ability to move the part toward test position against gravity almost to completion, or to completion with slight assistance or the ability to complete the arc of motion with gravity lessened.

KENDALL LOVETT DESCRIPTION
30 %20 % Poor +Poor The ability to move the part through partial arc of motion with gravity lessened; moderate arc, 30% or poor +; small arc, 20% or poor. To avoid moving a patient into gravity-lessened position, these grades may be estimated on the basis of the amount of assistance given during anti-gravity test movements: A 30% or poor + muscle requires moderate assistance, a 20% or poor muscle requires more assistance
10 %5 % Poor -Trace In muscles that can be seen or palpated, a feeble contraction may be felt in the muscle, or the tendon may become prominent during the muscle contraction, but there is no visible movement of the part.
0 % Gone No contraction felt in the muscle.
