Abstract

Neuroscience
Abstract figure legend Previous work in humans and rodents has identified transcutaneous spinal cord stimulation as a promising strategy to reduce spasticity and hyperreflexia after spinal cord injury. The objective of this study was to deliver stimulation protocols with the intensity set (1) above motor threshold, (2) below motor threshold or (3) alternating between supra‐and subthreshold; and evaluate whether it differentially influences diverse outcome measures associated with spasticity, including low frequency‐dependent depression of the H‐reflex, motor responses in response to ankle stretch and toe pinch, and the expression of KCC2 protein in lumbar motoneurons.
