Temporal synchronization during bilateral foot-tapping and its relationship with gait disturbance in patients with Parkinson's disease

Objective

Previous studies using finger-tapping tasks have shown that patients with Parkinson's disease (PD) exhibit a deficit of temporal processing linked to gait disturbance. In this study, we aimed to investigate abnormalities in lower-limb rhythmic control and their association with freezing of gait in PD using a bilateral foot-tapping task.
