Impaired Hyperemic Response to Exercise Post Stroke.
Autor: Matthew J Durand, Spencer A Murphy, Kathleen K Schaefer, Sandra K Hunter, Brian D Schmit, David D Gutterman, Allison S Hyngstrom
Publikováno v: PLoS ONE, Vol 10, Iss 12, p e0144023 (2015)
Individuals with chronic stroke have reduced perfusion of the paretic lower limb at rest; however, the hyperemic response to graded muscle contractions in this patient population has not been examined. This study quantified blood flow to the paretic

Stroke increases ischemia-related decreases in motor unit discharge rates
Autor: Brian D. Schmit, Matthew J. Durand, Spencer A. Murphy, Sandra K. Hunter, Dario Farina, Allison S. Hyngstrom, Francesco Negro, Tanya Onushko
Publikováno v: Journal of Neurophysiology
Following stroke, hyperexcitable sensory pathways, such as the group III/IV afferents that are sensitive to ischemia, may inhibit paretic motor neurons during exercise. We quantified the effects of whole leg ischemia on paretic vastus lateralis motor

Ischemic Conditioning Increases Strength and Volitional Activation of Paretic Muscle in Chronic Stroke: A Pilot Study
Autor: Jennifer N Nguyen, Allison S. Hyngstrom, David D. Gutterman, Matthew J. Durand, Brian D. Schmit, Spencer A. Murphy, Francesco Negro
Publikováno v: Journal of Applied Physiology
Ischemic conditioning (IC) on the arm or leg has emerged as an intervention to improve strength and performance in healthy populations, but the effects on neurological populations are unknown. The purpose of this study was to quantify the effects of

Abstract TP150: Two Weeks of Ischemic Preconditioning Training on the Paretic Leg Improves Leg Strength and Delays Muscle Fatigue in Chronic Stroke
Autor: Matthew J. Durand, David D. Gutterman, Allison S. Hyngstrom, Brian D. Schmit, Spencer A. Murphy
Publikováno v: Stroke. 48
Introduction: Individuals living with chronic stroke have weakness and increased neuromuscular fatigue in the paretic leg, which can limit walking ability and endurance. In cardiac and healthy populations, ischemic preconditioning (IPC) is a widely s

Impaired Regulation Post-stroke of Motor Unit Firing Behavior During Volitional Relaxation of Knee Extensor Torque Assessed Using High Density Surface EMG Decomposition
Autor: Brian D. Schmit, Spencer A. Murphy, Reivian Berrios, Dario Farina, Allison S. Hyngstrom, Francesco Negro, P. Andrew Nelson
Publikováno v: EMBC
The purpose of this study was to use high density surface EMG recordings to quantify stroke-related abnormalities in motor unit firing behavior during repeated sub-maximal knee extensor contractions. A high density surface EMG system (sEMG) was used
