Table 1 The (standard) MRC-scale of muscle strength/weakness
From: Using 4+ to grade near-normal muscle strength does not improve agreement
Grade | Description |
|---|---|
0 | No contraction |
1 | Flicker or trace of contraction |
2 | Full range of active movement, with gravity eliminated |
3 | Active movement against gravity |
4 | Active movement against gravity and resistance |
5 | Normal power |
