Brain stimulation device could improve motor function after stroke

February 21, 2020

A non-invasive magnetic stimulation headset could improve motor function in stroke patients, a new study has found.

In a clinical trial of 30 patients who had survived chronic ischemic strokes, the transcranial rotating permanent magnet stimulator (TRPMS) produced significant increases in physiological brain activity in areas near the stroke site. Brain activity was measured using functional magnetic resonance imaging (fMRI).

Houston Methodist Hospital Eddy Scurlock Stroke Center director Dr David Chiu said: “The robustness of the increase in physiological brain activity was surprising. With only 30 subjects, a statistically significant change was seen in brain activity.”
