PMID-16758482 "Paradoxical kinesis" is not a hallmark of Parkinson's disease but a general property of the motor system.
- Paradoxical kinesis is the idea that PD patients will suddenly spring to movement when propted by an extreme situation.
- "Results showed that external cues and urgent conditions decreased movement duration (Urgent External Cue < External Cue < Self Generated) and reaction time (Urgent External Cue < External Cue)"
- Results indicate that there is no difference in speed or reaction time improvement between controls and PD patients; it is a general property of the motor system.
