Cerebellar Reaching Ataxia is Exacerbated by Timing Demands and Assistive Interaction Torques

This study examines how timing demands and interaction torques affect reaching accuracy in individuals with cerebellar ataxia, finding increased errors and variability in movement coordination.

Feedback and feedforward control are differentially delayed in cerebellar ataxia

This study examines movement control in cerebellar ataxia, finding preserved feedforward and feedback control structures but increased delays and reduced feedback gain, with preview information improving performance.

Cerebellar patients have intact feedback control that can be leveraged to improve reaching

This study shows cerebellar patients have intact feedback control but with more phase lag, which can be improved by altering visual feedback in a virtual reality setup.
