t-RNS After Hand Recovery in Chronic Stroke

The primary purpose of this study was to investigate whether combining transcranial random noise stimulation with functional electrical stimulation-facilitated task practice will enhance hand function in individuals with severe paresis post-stroke than functional electrical stimulation alone. The study is an experimental randomized study comparing the effects of transcranial random noise stimulation with functional electrical stimulation to functional electrical stimulation alone on recovery of function in the more-affected hand in individuals with chronic stroke. Participants were randomized to receive transcranial random noise stimulation and functional electrical stimulation-facilitated task practice or sham-transcranial random noise stimulation and functional electrical stimulation-facilitated task practice. Participants received 18 treatment sessions over 6 weeks (3 times/week for 6 weeks).
