Case Report
Central Nervous System Demyelination in a Charcot-Marie-Tooth Type 1A Patient
Table 1
Comparative motor and sensory conduction studies of the patient at diagnosis of CMT and during present evaluation.
| Conduction studies† | Nerve | Motor conduction | Conduction velocity (m/s) | Amplitude (mV) | Latency (ms) |
| Median R | 36.5/36 | 3.5/4.5 | 5.8/5.0 | Ulnar R | 38/42 | 5.0/3.5 | 3.9/3.4 | Peroneal R | 23/ND | 0.2/ND | 8.8/ND | Tibial R | 30/27 | 0.5/0.28 | 9.2/9.8 |
| Sensory conduction | Conduction velocity (m/s) | Amplitude (μV) | Latency (ms) |
| Median R | 38/42 | 1.5/1.9 | 4.7/4.3 | Ulnar R | 39/ND | 2/ND | 4.2/ND | Sural R | 36/32 | 2.5/2.2 | 2.5/3.9 | Peroneal R | Could not be elicited |
