“…Additional examples of neurological disorders with abnormal saccades and postural instability other than PD [ 182 , 183 ] include progressive supranuclear palsy [ 184 ], cerebellar ataxia [ 185 ], essential tremor [ 186 ], and Huntington disease [ 187 , 188 ]. Some studies have reported that abnormalities in saccadic eye movements are correlated with body sway, even in healthy individuals [ 189 , 190 ].…”

Human locomotion involves a complex interplay among multiple brain regions and depends on constant feedback from the visual system. We summarize here the current understanding of the relationship among fixations, saccades, and gait as observed in studies sampling eye movements during locomotion, through a review of the literature and a synthesis of the relevant knowledge on the topic. A significant overlap in locomotor and saccadic neural circuitry exists that may support this relationship. Several animal studies have identified potential integration nodes between these overlapping circuitries. Behavioral studies that explored the relationship of saccadic and gait-related impairments in normal conditions and in various disease states are also discussed. Eye movements and locomotion share many underlying neural circuits, and further studies can leverage this interplay for diagnostic and therapeutic purposes.
