Nerve conduction studies
| NP definite | NP probable | |
|---|---|---|
| NP, neurophysiologically; SNAP, sensory nerve action potentials. | ||
| *p = 0.046, t test significant; **p<0.001, t test significant. | ||
| n (%) | 27 (54) | 23 (46) |
| Motor nerves tested, mean (range) | 5 (3–8) | 4.3 (2–8) |
| Sensory nerves tested, mean (range) | 4.3 (2–8) | 3.8 (1–8) |
| Patients with inexcitable nerves, n (%) | 8 (29.6) | 5 (21.7) |
| Patients with absent SNAP, n (%) | 21 (77.8) | 16 (69.6)* |
| Number of demyelinated motor | 3.7 (3–7) | 1.6 (0–2)** |
| nerves, mean (range) | ||
| Number of demyelinated | ||
| abnormalities, mean (range) | 6.4 (3–10) | 1.9 (0–6)** |
