Paroxysmal kinesigenic dyskinesias in a professional runner. Segment 1. Recording of a running session. This segment shows involuntary bilateral hand twisting movements (white arrows) presenting at the end of the sprint of a short running path. The patient complains also facial grimace and leg tightness (not shown). Segment 2. Neurological examination and provoking maneuver (running in place). This segment shows an unremarkable finger-tapping test in the beginning of the examination. The exercise provokes after 10 seconds the onset of bilateral hand dystonia with left clenched fist and right hand twisting posture. The finger tapping performances at the end of the segment are impaired by bradykinesia and dystonic jerks.
