Impairment in the behavioral control of body sway, gaze shift, and mental workload in Parkinson’s disease by Yann-Romain Kechabia, Luc Defebvre, Arnaud Delval, Cédrick T. Bonnet

“…PD patients showed a higher amplitude in gaze shifts and body sway than age-matched controls. The adaptation of gaze shift and body sway velocity from free-viewing to searching was smaller in PD patients. …”

Anterior–posterior and medial-lateral balance metrics are unchanged when two-dimensional pseudorandom motion perturbations are provided in semicircular canal coordinates by Manami Fujii, Manami Fujii, Sophia G. Chirumbole, Andrew R. Wagner, Jaclyn B. Caccese, Ajit M. W. Chaudhari, Ajit M. W. Chaudhari, Ajit M. W. Chaudhari, Wei Wang, Wei Wang, Bo Lu, Daniel M. Merfeld, Daniel M. Merfeld, Daniel M. Merfeld, Daniel M. Merfeld

“…IntroductionExternal continuous perturbations using a motion platform have been developed by employing either sum-of-sines (SoS) or a pseudorandom ternary sequence (PRTS) of numbers to quantify body sway evoked in the medial-lateral (ML) or anterior-posterior (AP) directions, which ultimately helps understand the human postural control system. …”
