TABLE 32-41 Muscle Strength Grading Scheme

No evidence of contractility

*Grade*: 0 *%Normal*: 0 *Lovett Scale* 0 (zero)

Slight Contractility, no movement

*Grade*: 1 *%Normal*: 10 *Lovett Scale*: T (trace)

Full range of motion, gravity eliminated

*Grade*: 2 *%Normal*: 25 *Lovett Scale*: P (poor)

Full range of motion with gravity

*Grade*: 3 *%Normal*: 50 *Lovett Scale*: F (fair)

Full range of motion against gravity, some resistance

*Grade*: 4 *%Normal*: 75 *Lovett Scale*: G (good)

Full range of motion against gravity, full resistance

*Grade*: 5 *%Normal*: 100 *Lovett Scale*: N (normal)
