A first-of-its kind device that helps people disabled by stroke regain significant control over their arm and hand function by using their minds has received market authorization from the Food and Drug Administration (FDA). The IpsiHand Upper Extremity Rehabilitation System, developed by Neurolutions Inc. — a Washington University in St. Louis startup company — leverages brain-computer interface (BCI) technology licensed from the university.
The IpsiHand system includes a wearable robotic exoskeleton that fits over a patient’s hand and wrist and assists with opening and closing the hand based on the patient’s thoughts. By mentally controlling the IpsiHand exoskeleton with the aid of BCI technology, patients may improve their upper extremity motor function, giving them more purposeful and effective movement of the affected hand, wrist and arm. Designed for use in the home or clinic, the IpsiHand system may assist stroke patients in recovering critical abilities such as feeding themselves, grasping objects and performing other everyday tasks, and is the first stroke-rehabilitation device that relies on a brain-computer interface… Continue reading.
Device reads brain signals, converts them into motion

Stroke patients who learned to use their minds to open and close a device fitted over their paralyzed hands gained some control over their hands, according to a new study from Washington University School of Medicine in St. Louis.
By mentally controlling the device with the help of a brain-computer interface, participants trained the uninjured parts of their brains to take over functions previously performed by injured areas of the brain, the researchers said.
Leuthardt played a key role in elucidating the basic science, and he worked with Daniel Moran, a professor of biomedical engineering at Washington University School of Engineering & Applied Science, to develop the technology behind the Ipsihand. He and Moran co-founded the company Neurolutions Inc. to continue developing the Ipsihand, and Leuthardt serves on the company’s board of directors. Neurolutions funded this study.
To test the Ipsihand, Huskey recruited moderately to severely impaired stroke patients and trained them to use the device at home. The participants were encouraged to use the device at least five days a week, for 10 minutes to two hours a day. Thirteen patients began therapy, but three dropped out due to unrelated health issues, poor fit of the device or inability to comply with the time commitment. Ten patients completed the study… Continue reading.
WASHINGTON, D.C.— The American Institute for Medical and Biological Engineering (AIMBE) has announced the pending induction of Daniel W. Moran, Ph.D., Professor of Biomedical Engineering, Neurobiology, Neurosurgery, and Physical Therapy, Biomedical Engineering, Washington University in St. Louis, to its College of Fellows. Dr. Moran was nominated, reviewed, and elected by peers and members of the College of Fellows For outstanding contributions to the development of novel brain-computer interface technologies for chronic communication and control.
