Percentile ranking of F chronodispersion and persistence
| Parameter | Nerve | Median (ms) | 95th percentile (5th for persistence) |
|---|---|---|---|
| Fc | Peroneal | 6.49 | 10.59 |
| Posterior tibial | 5.31 | 9.45 | |
| Median | 4.48 | 8.92 | |
| Ulnar | 3.61 | 8.7 | |
| Fp | Peroneal | 9 | 3 |
| Posterior tibial | 10 | 9 | |
| Median | 9 | 6 | |
| Ulnar | 10 | 8 |
Note the large normal values for Fc, especially in the peroneal nerve (extensor digitorum brevis muscle).28
