Dr. Plotnik is a senior researcher in the Laboratory for Gait and Neurodynamics at the Tel Aviv Sourasky Medical Center and an assistant professor in the Department of Physiology and Pharmacology in the Sackler School of Medicine of the Tel Aviv University (TAU). He began his graduate studies pursuing an MSc in Physiology (TAU) and investigating motor control in Parkinson's disease (PD). At the Hebrew University in Jerusalem, his PhD degree (physiology) thesis investigated vestibular evoked potentials. His post-doctoral studies in the Department of Neurobiology at the University of Chicago examined the efferent vestibular system. In recent years, his research has focused on gait and equilibrium in healthy and neurologically diseased human subjects. In particular, he proposed a hypothesis for the mechanism underlying the freezing of gait phenomenon in subjects with PD and provided evidence suggesting that it is linked to impaired bilateral coordination of gait.
