| No Movement | 0 | 0 | No contraction felt or seen in the muscle |
| T | 1 | Tendon becomes prominent or feeble contraction felt in muscle with no visible movement | |
| Tested in Antigravity Position | P− | 2− | Movement through partial ROM |
| P | 2 | Movement through complete ROM for the muscle being tested | |
| P+ | 2+ | Holds against slight pressure in test position; Moves through partial ROM against gravity | |
| Tested in Gravity Dependent Position | F− | 3− | Gradual release from test position occurs |
| F | 3 | Hold test position (no added pressure) | |
| F+ | 3+ | Holds test position against slight pressure | |
| G− | 4− | Holds test position against slight to moderate pressure | |
| G | 4 | Holds test position against moderate pressure | |
| G+ | 4+ | Holds test position against moderate to strong pressure | |
