abstract = "A shifted field of view, an altered perception of optic flow speed, and gait asymmetries may influence heading direction in Parkinson's disease (PD). PD participants (left body-side onset, LPD, n=14; right body-side onset, RPD, n=9) and Healthy Control participants (n=17) walked a virtual hallway in which the optic flow speeds of the walls varied. Three-dimensional kinematics showed participants veered away from the faster moving wall. Although veering normally occurs toward the side with smaller step length, in both LPD and RPD this bias was overridden by a shifted field of view, which caused veering in the opposite direction, toward the side of the brain with more basal ganglia damage.",

We gratefully thank Erik Giphart from the Steadman-Hawkins Sports Medicine Foundation, Chris Lawlor from the Electronics Design Facility at Boston University, and Tami Rork DeAngelis from the Center for Neurorehabilitation at Boston University for their invaluable support. Our efforts to recruit patients with PD were generously supported by Marie Saint-Hilaire, MD, and Cathi Thomas, RN, MS, of Boston University Medical Center Neurology Associates and by Boston area Parkinson Disease support groups. Most importantly, we thank all of the individuals who participated in this study.",
