Study Arms:
- Segmentary dystonia (Type: OTHER): to identify movement-related functional magnetic resonance imaging (fMRI) activation patterns
- Hemidystonia (Type: OTHER): to identify movement-related functional magnetic resonance imaging (fMRI) activation patterns
- Generalized dystonia (Type: OTHER): to identify movement-related functional magnetic resonance imaging (fMRI) activation patterns
- Healthy control subjects (Type: OTHER): to identify movement-related functional magnetic resonance imaging (fMRI) activation patterns

Based on this trial design, predict the completion outcome and termination type (if applicable).
