Dr. A. Aria TzikaThe Washington Post article Robotic Device Could Help Stroke Patients said
U.S. researchers say they’ve developed a hand-exercising robotic device that appears to help stroke victims recover motor skills, even more than six months after a stroke.
Brain scans suggested that the device, which patients squeeze with their stroke-afflicted hands, boosted activity in the part of the brain that handles use of the hands.
“There’s still hope in these patients with chronic stroke who have had a stroke a long time ago. If they do the right type of exercises, they can get better,” said A. Aria Tzika, director of the NMR Surgical Laboratory at Massachusetts General Hospital and lead author of a study released Wednesday at the Radiological Society of North America annual meeting, in Chicago.

Aria’s research focuses on the use of advanced imaging methodology, including multi-parametric, functional, and physiological and molecular MR imaging and MR spectroscopy, to assess different states of tissue pathology. The aims of this research are to elucidate mechanisms underlying neoplasia, injury, and inflammation. Biologically important biomarkers are currently being identified and characterized in experimental tissue and animal models. The goals of this research are to move from in vitro and ex vivo biology to in vivo physiology and integrative biology; to integrate research in experimental animal models with clinical research and medicine; and to develop therapies for neoplasia, injury, and inflammation.
