Effects of water immersion on short- and long-latency afferent inhibition, short-interval intracortical inhibition, and intracortical facilitation.

•We demonstrate that water immersion (WI) modulates sensorimotor integration as indicated by decreased short- and long-latency afferent inhibition.•WI did not change corticospinal excitability, short-interval intracortical inhibition, or intracortical facilitation.•A greater understanding of the neurophysiological effects of WI could lead to more efficacious use of aquatic therapy in rehabilitation regimens.
