If the patient is able to extend the leg against gravity, but cannot overcome any other resistance, the muscle strength is considered fair, indicating that the muscle can move the body part against gravity but not against resistance. A normal grade (5/5) indicates that the muscle can overcome resistance, while a good grade (4/5) indicates that the muscle can move the body part against some resistance, but not against full resistance. Poor (2/5) and trace (1/5) grades indicate that the muscle is weaker and cannot move the body part against gravity.
