Motor nerve conduction studies
| Nerve | Study | DML (ms) | CV (m/s) | Amplitude (distal/proximal) (mV) |
|---|---|---|---|---|
| Amplitude, peak to peak amplitude of compound muscle action potential; study 1, at presentation; study 2, two weeks later; study 3, six weeks later. | ||||
| CV, conduction velocity; DML, distal motor latency. | ||||
