Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Increased impairment of the hand is commonly reported as an outcome occurring after a stroke. This impairment is due mainly to the decreased ability to modulate appropriate muscle activation patterns. Issues with appropriately modifying activation patterns can profoundly affect tasks of daily living. This study is evaluating a novel software focusing on retraining hand muscle activation patterns through an Electromyographic (EMG) controlled game. Stroke survivors with chronic, severe hemiparesis of the hand will participate in a longitudinal study consisting of 3 weeks of training. We hypothesize that stroke survivors will experience a decrease in time to complete a test of EMG control, as well as improvement in hand motor control.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Single, unilateral stroke at least 6 months prior to enrollment
* Moderate hand impairment defined by Stage 4 or Stage 5 on the Chedoke McMaster Stroke Assessment Scale

Exclusion Criteria

* Visual neglect or deficits (with inability to compensate)
* Upper extremity orthopedic conditions that interfere with movement
* Cerebellar stroke

Children, prisoners, or adult unable to provide consent will not be recruited. As the procedures pose no increased risk for pregnant women, we will not specifically exclude them.
