A National Cross-Sectional Survey of EMG Physician Volume.

This national, cross-sectional survey evaluates average metrics of EMG volume. Our survey showed that the median number of EMGs annually lies between 251 and 500 studies (37%). In addition, for those respondents who allotted a dedicated half-day to performing EMGs, the median number of EMG studies scheduled per half-day lies between 3 and 4 studies (45%). In multivariate analysis, respondent characteristics of age of the physician (older than 45), working with nerve conduction technologists, and holding the position of EMG director were associated with increased EMG volume.
