| n = 64 | Basal (%) | Final (%) | p Value |
|---|---|---|---|
| SEP‐UL | 51.6 | 65.6 | 0.03 |
| SEP‐LL | 81.3 | 85.9 | NS |
| SEP | 84.4 | 89.1 | NS |
| MEP‐UL | 68.8 | 70.3 | NS |
| MEP‐LL | 71.9 | 79.7 | NS |
| MEP | 73.4 | 79.7 | NS |
| VEP | 75.0 | 82.8 | NS |
| BAEP | 40.6 | 50.0 | NS |

BAEP, brain stem auditory evoked potential; EP, evoked potential; LL, lower limb; MEP, motor evoked potential; NS, not significant; SEP, somatosensory evoked potential; UL, upper limb; VEP, visual evoked potential.
p Values of differences (right column) represent McNemar's test.
