Merging of healthy motor modules predicts reduced locomotor performance and muscle coordination complexity post-stroke.
A common modular organization of muscle coordination underlying walking in both healthy and post-stroke subjects is suggested, which may lead to new insight into impaired locomotor coordination and the underlying neural systems. Expand
Muscle synergy organization is robust across a variety of postural perturbations.
The robustness of synergy organization across perturbation types, postures, and animals suggests that muscle synergies controlling task-variables are a general construct used by the CNS for balance control. Expand
A limited set of muscle synergies for force control during a postural task.
It is suggested that, within the context of active balance control, postural synergies reflect a neural command signal that specifies endpoint force of a limb. Expand
Muscle synergies characterizing human postural responses.
The results suggest that muscle synergies represent a general neural strategy underlying muscle coordination in postural tasks that represents variations in the amplitude of descending neural commands that activate individual Muscle synergies. Expand
Leg design in hexapedal runners.
To explain how diverse leg designs can result in common whole-body dynamics, a miniature force platform was used to measure the ground reaction forces produced by individual legs of the cockroach Blaberus discoidalis and showed that deviations from the minimum moments may be explained by considering the minimization of the summed muscle forces in more than one leg.

Dynamic and static stability in hexapedal runners.
Running cockroaches met the criteria for static stability over a wide range of speeds, yet several locomotor variables changed in a way that revealed an increase in the importance of dynamic stability as speed increased, indicating instances of static instability at fast speeds. Expand

The identification of muscle synergies has strong implications for the organization and structure of the nervous system, providing a mechanism by which task-level motor intentions are translated into detailed, low-level muscle activation patterns. Expand

This work proposes a hierarchical feedback control system that allows the nervous system the simplicity of performing goal-directed computations in task-variable space, while maintaining the robustness afforded by redundant sensory and motor systems. Expand
Accuracy of force and center of pressure measures of the Wii Balance Board.
The WBB may be useful for low-resolution measurements, but should not be considered as a replacement for laboratory-grade force plates, rather than absolute measurement across devices. Expand
