Journal ArticleDOI
Alterations in upper limb muscle synergy structure in chronic stroke survivors
Jinsook Roh,William Z. Rymer,William Z. Rymer,Eric J. Perreault,Eric J. Perreault,Seng Bum Yoo,Seng Bum Yoo,Randall F. Beer,Randall F. Beer +8 more
TL;DR: The results suggest that an impaired control of the individual deltoid heads may contribute to poststroke deficits in arm function.
Journal ArticleDOI
The number and choice of muscles impact the results of muscle synergy analyses
Katherine M. Steele,Katherine M. Steele,Matthew C. Tresch,Matthew C. Tresch,Eric J. Perreault,Eric J. Perreault +5 more
TL;DR: This study used a musculoskeletal model to calculate muscle activations required to perform an isometric upper-extremity task and determined that the structure of synergies is dependent upon the number and choice of muscles included in the analysis, which significantly improved similarity to the master set.
Journal ArticleDOI
Estimation of Human Ankle Impedance During the Stance Phase of Walking
TL;DR: The specifications for a biomimetic powered ankle prosthesis were introduced that would accurately emulate human ankle impedance during locomotion using a model consisting of stiffness, damping and inertia.
Journal ArticleDOI
Effects of voluntary force generation on the elastic components of endpoint stiffness
TL;DR: Endpoint stiffness was estimated during the application of planar, stochastic displacement perturbations to the human arm to result in a nearly posture-independent regulation of joint torque-stiffness relationships, suggesting a simplified strategy that is used to regulate arm mechanics during these tasks.
Journal ArticleDOI
Multijoint dynamics and postural stability of the human arm
TL;DR: This work examined whether the dynamic stability of the limb remained nearly invariant across a range of voluntarily generated endpoint forces and limb postures and found that in the tasks studied, there was a differential modulation of endpoint elasticity and endpoint viscosity.
