- Discussion:
- demyelinating neuropathies are characterized by slowing of conduction velocities
and latencies, including those of late responses such as F waves;
- this occurs well before clinical symptoms appear.
- slowing of the conduction velocity is often > 40% of the normal mean;
- EMG of pt who has neuropathic disorder shows an increased amplitude and
duration of response;
- in contrast, patients w/
myopathic disorders will show a decreased
amplitude and duration of response;
