False Positive Hoover's Sign in Apraxia
Ercoli, Tommaso; Stone, Jon
No abstract, end of paper:
All clinical signs have their limitations.
This case reinforces that any positive sign of FND should always be interpreted in the context of the whole clinical picture.
In this case, the presence of apraxia was a clear alternative explanation for the positive Hoover's sign rendering the sign nondiagnostic.
Dissociated emotional and voluntary facial movement in opercular syndrome, improvement when walking backward or running in dystonia, aura of paroxysmal kinesigenic dyskinesia, and the ability to suppress movements in Tourette's syndrome are examples of similar diagnostic pitfalls.
