Study Notes

Grade 0: No contraction
Grade 1: Flicker of movement
Grade 2: Active horizontal movement, with gravity eliminated
Grade 3: Active horizontal movement against gravity
Grade 4: Active movement against gravity and minimal resistance, which the examiner can overcome
Grade 5: Normal power

Grade 0: No increase in muscle tone
Grade 1: Slight increase in muscle tone, manifested by a catch and release or minimal resistance at the end of the range of motion
Grade 1+: Slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the remainder of the range of motion
Grade 2: Marked increase in muscle tone throughout the range of motion, but affected part(s) are easily moved
Grade 3: Considerable increase in muscle tone, passive movement is difficult
Grade 4: Affected part(s) rigid in flexion and extension

Grade 0: Absent (Areflexia)
Grade 1: Reduced (Hyporeflexia), contraction of the muscle with no movement of the joint
Grade 2: Normal, contraction of the muscle and movement of the joint
Grade 3: Increased (Hyperreflexia), contraction of the muscle and movement of more than 1 joint
Clonus: Jerking the wrist/ankle back will give 5 or more flaps
