Observation
Involuntary Movements
Muscle Symmetry
Left to Right
Proximal vs. Distal
Atrophy
Pay particular attention to the hands, shoulders, and thighs.
Gait
Muscle Tone
Ask the patient to relax.
Flex and extend the patient's fingers, wrist, and elbow.
Flex and extend patient's ankle and knee.
There is normally a small, continuous resistance to passive movement.
Observe for decreased (flaccid) or increased (rigid/spastic) tone.
Muscle Strength
Test strength by having the patient move against your resistance.
Always compare one side to the other.
Grade strength on a scale from 0 to 5 "out of five":
| Grading Motor Strength | |
| Grade | Description |
| 0/5 | No muscle movement |
| 1/5 | Visible muscle movement, but no movement at the joint |
| 2/5 | Movement at the joint, but not against gravity |
| 3/5 | Movement against gravity, but not against added resistance |
| 4/5 | Movement against resistance, but less than normal |
| 5/5 | Normal strength |
