| Reference | Muscle | Test side | Number of participants | SCI (ms) | Healthy controls (ms) |
|---|---|---|---|---|---|
| Davey et al., 1998 (46) | Thenar Muscles | More Affected Side (lateralized symptoms) OR ELSE Dominant Side (Right) | SCI = 10 AB = 10 | Rest = 27.7 (SE = 1.3) Active = 27.6 (SE = 1.3) | Rest = 21.3 (SE = 0.5) Active = 19.8 (SE = 0.5) |
| Alexeeva et al., 1998 (53) | Soleus | SCI: Stronger Side AB: Left Side | SCI = 10 AB = 20 | 42.5 (18.4) | 34.0 (14.5) |

| Smith et al., 2000 (45) | Thenar Muscles | More Affected Side (lateralized symptoms) OR ELSE Dominant Side (Right) | SCI = 21 AB = 10 | 51–100 days post injury: Rest = 27 (SE = 1.2) Active = 26 (SE = 0.8) | 51–100 days post injury: Rest = 21 (SE = 0.6) Active = 20 (SE = 0.5) |
