Evidence for constancy in the modularity of trunk muscle activity preceding reaching: implications for the role of preparatory postural activity
Alexander Stamenkovic, Lena H. Ting, Paul J. Stapley
Abstract
Reaching within and beyond arm's length places different task constraints upon the required trunk motion necessary for successful movement execution. The identification of constant modular features, including functional muscle weightings and spatial tuning, lend support to the notion that preparatory postural adjustments of the trunk are tied to the same task priorities driving mobility, regardless of the future postural constraints.
