Muscle synergies characterizing human postural responses.
Postural control is a natural behavior that requires the spatial and temporal coordination of multiple muscles. Complex muscle activation patterns characterizing postural responses suggest the need for independent muscle control. However, our previous work shows that postural responses in cats can be robustly reproduced by the activation of a few muscle synergies. We now investigate whether a s...
متن کاملMuscle synergies with Walkaround® postural support vs. "cane/therapist" assistance.
BACKGROUND The main clinical measures of walking recovery in stroke patients were compared for training assisted by Walkaround® postural support (WPS) and conventional (CON) support by a cane/therapist. OBJECTIVE We attributed the differences between the trainings to modified muscular synergies that occurred during assistance by WPS. METHODS We studied the muscle activities of the primary k...
متن کاملFunctional muscle synergies constrain force production during postural tasks.
We recently demonstrated that a set of five functional muscle synergies were sufficient to characterize both hindlimb muscle activity and active forces during automatic postural responses in cats standing at multiple postural configurations. This characterization depended critically upon the assumption that the endpoint force vector (synergy force vector) produced by the activation of each musc...
متن کاملAction Direction of Muscle Synergies in Voluntary Multi-Directional Postural Control
A muscle synergy is a coordinative structure of muscles that has been proposed as a strategy to reduce the number of variables that the central nervous system (CNS) has to address in motor tasks. In this article, the mechanical contribution of muscle synergies and coordinative structures of muscles in voluntary multi-directional postural control were investigated. The task for healthy, young su...
متن کاملPostural Synergies and Their Development
The recent developments of a particular approach to analyzing motor synergies based on the principle of motor abundance has allowed a quantitative assessment of multi-effector coordination in motor tasks involving anticipatory adjustments to self-triggered postural perturbations and in voluntary postural sway. This approach, the uncontrolled manifold (UCM) hypothesis, is based on an assumption ...
