Functional hemiballism of a drummer

We report an acute right-sided functional hemiballistic syndrome of the upp er and lower limb combined with functional choreatic symptoms of the right forearm and hand of an 59 year old drummer. After a wide range of diagnosti c procedures, no somatic reasons could be delineated. Finally a lifetime as sociated syndrome could be elucidated. We therefore reviewed possible diagn ostic and methodical neurological and psychosomatic aspects of functional h emiballism.
