t-RNS After Hand Recovery in Chronic Stroke

Participants were randomized to one of the two intervention groups \[transcranial current stimulation (tRNS) and functional electrical stimulation (FES) or FES with sham tRNS\] before pre-intervention testing. After randomization, participants underwent pre-intervention testing, followed by intervention 3 times per week for 6 weeks. Each intervention session lasted for 1 hour, where tRNS or sham-tRNS were delivered concurrently with the FES-facilitated task practice. tRNS or sham-tRNS was delivered for the first 30 minutes. Both tRNS and sham tRNS were delivered by the Starstim system. FES was delivered using the Neuromove system. All participants were treated by a licensed occupational therapist, who was trained on a manualized protocol.
