The aim of this paper is to understand how lower limb proprioception effects a dual task paradigm, while maintaining postural stability. A dual task paradigm involving collision avoidance and maintaining stability in single limb stance have been designed as a Virtual Reality game, using Kinect and played with `Google Virtual Reality' device. Five healthy subjects played the game for four consecutive days. Neural interplay and effect of proprioceptive adaptation were modeled in terms of muscle co-activation, sway of Centre of Mass, collision rate and a smoothness function of knee joint trajectory. Findings from this study would help to better understand the dual task paradigm for lower limb, task prioritization and effect of proprioceptive adaptation on motor task.
