    • Early and Late Components of Feed-forward Postural Adjustments to Predictable Perturbations 

      Krishnan, Vennila; Latash, Mark L.; Aruin, Alexander S. (Elsevier, 2012-05)
      Objectives: The purpose was to investigate two types of feed-forward postural adjustments associated with preparation to predictable external perturbations. Methods: Nine subjects stood on a wedge, toes-up or toes-down ...
    • The effect of decreased visual acuity on control of posture 

      Mohapatra, Sambit; Krishnan, Vennila; Aruin, Alexander S. (Elsevier, 2012-01)
      Objectives: The goal of this study was to investigate the effect of visual acuity on the anticipatory (APAs) and compensatory (CPAs) components of postural control. Methods: Ten individuals participated in the experiments ...
    • Postural control in standing: role of vision and additional support 

      Krishnan, Vennila; Aruin, Alexander S. (Springer Verlag, 2011-07)
      The purpose of the study was to investigate the availability of vision and additional support on anticipatory (APAs) and compensatory (CPAs) postural adjustments and their interaction. Eight healthy adults were exposed ...
    • Two stages and three components of the postural preparation to action 

      Krishnan, Vennila; Aruin, Alexander S.; Latash, Mark L. (Springer Verlag, 2011-07)
      Previous studies of postural preparation to action/perturbation have primarily focused on anticipatory postural adjustments (APAs), the changes in muscle activation levels resulting in the production of net forces and ...
