Temporal discrimination thresholds and the blink reflex R2 recovery cycle in cervical dystonia

Takeaway

  • Temporal discrimination thresholds (TDTs), but not the blink reflex R2 recovery cycle (BRRC), are significantly elevated for those with cervical dystonia (CD) compared with healthy controls.

Why this matters

    This study indicates TDT may be an endophenotype of CD, which may be helpful in identifying asymptomatic mutation carriers.
