This study, for stroke survivors with partial paralysis of one arm, will test whether or not an arm exoskeleton (the MyoPro Motion-G) immediately impacts arm movement more than a regular brace or more than wearing no brace. A stroke survivor who is 1 year or more post-stroke will qualify for this study if he/she has at least a little movement in the more affected arm. Subjects who qualify will come to MUSC 4 times over 3 weeks for about 2-3 hours per visit. During that time subjects will be fit for, and learn how to operate the exoskeleton and the comparison brace. Subjects' arm movement will be tested with a series of standard clinical measures of dexterity, functional task performance, range of motion, and strength.
This study has 4 parts: In one part of this study, people with stroke will either play a custom designed computer game for stroke rehabilitation called Duck Duck Punch or an off the shelf computer game with their weaker arm 3 times per week for 6 weeks. Evaluations will determine whether or not one computer game improved arm movement more than the other. In the 2nd part of the study, people with stroke, caregivers of people with stroke and stroke rehabilitation therapists will meet in several focus groups to design a useful and informative Duck Duck Punch performance report. In the 3rd part of the study we will test the accuracy of the Duck Duck Punch tracking system. Finally, in the 4th part of the study, we will test a new online class to teach about how to carry on stroke rehabilitation after the therapy ends.
The purpose of this stroke rehabilitation study is to test the effects of a 10-session rehabilitation program that combines non-invasive brain stimulation (transcranial direct current stimulation, tDCS) with occupational therapy (OT) to improve movement and function in the paretic arm/hand. This study is motivated by the need for new ways to augment traditional rehabilitation programs in order to improve functional outcomes for adults (ages 21-81) with ongoing arm/hand weakness because of stroke that occurred within the previous 6 months to 7 years.
