Impact of speed on freezing of the upper limbs in Parkinson’s disease


  • Freezing of the upper limbs (FOUL) is more common in higher task demands, in those with gait freezing, and in those with cognitive impairment.

Why this matters ?

  • Imposing a higher speed in freezing-provoking writing tasks, and thus increasing task demands, increases sensitivity of FOUL detection for those with Parkinson’s disease (PD)
