The purpose of this study is to determine whether a novel treadmill training intervention can improve the gait stabilization strategy used by individuals who have experienced a stroke.
Every year, approximately 15,000 American Veterans experience a stroke, with an estimated cost of acute and follow-up care in the hundreds of millions of dollars. Following a stroke, the restoration or improvement of walking is a high-ranking goal among patients, but only about half of the population is able to return to typical levels of community ambulation. The resultant decrease in independent mobility is strongly associated with a decline in quality of life. Gait instability is a common contributor to limited mobility through either an increased fall-risk or fear of falling, but current interventions to address post-stroke gait instability have had limited success. This project will conduct initial testing of a novel elastic force-field designed to improve post-stroke gait stability through targeted motor learning. The results of these experiments will serve as the basis for the development of novel gait rehabilitation techniques, which have the potential to increase the quality of life of thousands of Veterans and save millions of dollars.

The purpose of this study is to investigate the process of acquiring a motor skill subject in post-stroke, comparing them with healthy subjects.
Modulating visual feedback may be a viable option to improve motor function after stroke, but the neurophysiological basis for this improvement is not clear. Visual gain can be manipulated by increasi...
Error detection in motor behavior is a fundamental cognitive function heavily relying on cortical information processing. Neural activity in the high-gamma frequency band (HGB) closely reflects such l...
Visual feedback that provides error information is critical to task quality and motor adjustments. This study investigated how the size of perceived errors via visual feedback affected rate control an...

The introduction of error due to systematic differences in the characteristics between those selected and those not selected for a given study. In sampling bias, error is the result of failure to ensure that all members of the reference population have a known chance of selection in the sample.
Work consisting of an acknowledgment of an error, issued by a publisher, editor, or author. It customarily cites the source where the error occurred, giving complete bibliographic data for retrieval. In the case of books and monographs, author, title, imprint, paging, and other helpful references will be given; in the case of journal articles, the author, title, paging, and journal reference will be shown. An erratum notice is variously cited as Errata or Corrigenda.
Information systems, usually computer-assisted, that enable providers to initiate medical procedures, prescribe medications, etc. These systems support medical decision-making and error-reduction during patient care.

Stroke - Cerebrovascular Disease (CVA)
A stroke is a serious medical condition that occurs when the blood supply to part of the brain is cut off. Strokes are a medical emergency and prompt treatment is essential because the sooner a person receives treatment for a stroke, the less damage is ...
