Table 1 Modified Ashworth scale
Grade | Assessment standard | Score |
|---|---|---|
0 | No increase in muscle tension | 0 |
1 | Muscle tension is increased slightly. When the affected part is passively flexed and stretched, it suddenly becomes stuck at the end of joint activity and then presents minimum resistance or release | 1 |
1+ | Muscle tension is increased slightly. Suddenly stuck in passive flexion and extension occurs within the last 50% of the range of ROM, and then shows minimal resistance | 2 |
2 | Muscle tension is increased significantly. Muscle tension of the affected limbs in passive motion increases significantly in most ROM ranges, but still easy to move | 3 |
3 | Muscle tension is increased severely. The affected limb’s passive movement has resistance over the whole ROM, so it is difficult to move | 4 |
4 | The affected part is rigid and inactive | 5 |
