A Novel Brain Stimulation for Bimanual Motor Function and Control in Chronic Stroke

Participants in this arm will receive rTMS-based facilitation of the contralesional higher motor cortices located in the non-stroke hemisphere before the start of each rehabilitation session. High-frequency rTMS (5Hz) will be delivered using 42 10 second trains of 50 pulses each (total 2100 pulses) for a period of 22 minutes. Immediately after the completion of rTMS, participants will undergo therapist-guided upper limb therapy for a total of one hour. Participants will receive these interventions 2 days a week for 6 weeks for a total of 12 sessions.

Participants in this arm will receive sham rTMS given over the contralesional higher motor cortices located in the non-stroke hemisphere before the start of each rehabilitation session. Immediately after the completion of sham rTMS, participants will undergo therapist-guided upper limb therapy for a total of one hour. Participants will receive these interventions 2 days a week for 6 weeks for a total of 12 sessions.
