โฆ Synopsis
Every major league baseball pitcher, most minor league pitchers, but only few amateur pitchers that we have studied have had reduced sensory nerve action potentials in the throwing arm. We present 6 clinical cases which demonstrate the spectrum of "pitcher's arm." These cases suggest that the phenomenon is a pathologic process, probably an example of a repetitive use syndrome affecting the brachial plexus. Although it does not appear to impact performance, it has clear implications for the interpretation of electrodiagnostic studies in symptomatic pitchers.
