This paper reanalyzes data to compare how reach-to-grasp movements are controlled in physical environments versus haptic-free virtual environments, finding differences in closure initiation control laws.

The paper uses multifractal analysis to differentiate reactive and proactive postural control mechanisms by examining non-Gaussian cascade processes in center of pressure fluctuations.

The paper shows that stringent postural tasks recruit shorter-timescale processes into non-Gaussian cascade dynamics, with specific statistical signatures observed in postural sway.
