Motor and sensory nerve conduction study findings in GBS cases
| Variable | (N = 24) | |
|---|---|---|
| N | % | |
| Motor nerve conduction study | ||
| Absent motor response | 5 | 20.8 |
| Slow CV | 9 | 37.5 |
| Prolonged distal latency | 16 | 66.7 |
| Low CMAP amplitude | 13 | 54.2 |
| F-wave abnormality | 17 | 70.8 |
| Sensory nerve conduction study | ||
| Prolonged latency | 4 | 16.7 |
| Absent response | 2 | 8.3 |
| Reduced SNAP amplitude | 4 | 16.7 |
Abnormality means finding in ≥ 2 nerves
CV conduction velocity, CMAP compound motor action potential, SNAP sensory-neural action potential
