Repetitive transcranial magnetic stimulation (rTMS), combined with hand therapy, is currently a research-based treatment. It is intended to help people with stroke achieve greater recovery of hand function. The hand weakness following a stroke stems from brain neurons destroyed by the stroke, as well as from surviving neurons. The surviving neurons become dormant (not active) through inactivity and suppression from the non-stroke hemisphere. In some patients, rTMS can help dormant neurons reactivate and thereby improve voluntary hand function.
