The purpose of this study was to quantify the effects of 12 sessions of ischemic conditioning (IC) on mean discharge rate and estimated common synaptic drive (CSD) during a fatiguing contraction in chronic stroke survivors. On average, following IC we found an increase in task duration and decreased oscillations in CSD at the beginning of the task. The results suggest that an IC intervention can improve aspects of rate coding during a fatiguing task and that IC could potentially be used as an adjunct to rehabilitation to optimize neuromuscular fatigability post stroke.

摘要

The purpose of this study was to quantify the effects of 12 sessions of ischemic conditioning (IC) on mean discharge rate and estimated common synaptic drive (CSD) during a fatiguing contraction in chronic stroke survivors. On average, following IC we found an increase in task duration and decreased oscillations in CSD at the beginning of the task. The results suggest that an IC intervention can improve aspects of rate coding during a fatiguing task and that IC could potentially be used as an adjunct to rehabilitation to optimize neuromuscular fatigability post stroke.
