Effect Of Behavioural Practice Targeted At The Motor Action Selection Network After Stroke, Jill C. Stewart Pt,Phd, Jessica F. Baird, Allison F. Lewis, Stacy L. Fritz, Julius Fridriksson Jul 2022

Effect Of Behavioural Practice Targeted At The Motor Action Selection Network After Stroke, Jill C. Stewart Pt,Phd, Jessica F. Baird, Allison F. Lewis, Stacy L. Fritz, Julius Fridriksson

Motor action selection engages a network of frontal and parietal brain regions. After stroke, individuals activate a similar network, however, activation is higher, especially in the contralesional hemisphere. The current study examined the effect of practice on action selection performance and brain activation after stroke. Sixteen individuals with chronic stroke (Upper Extremity Fugl–Meyer motor score range: 18–61) moved a joystick with the more-impaired hand in two conditions: Select (externally cued choice; move right or left based on an abstract rule) and Execute (simple response; move same direction every trial). On Day 1, reaction time (RT) was longer in Select compared …

Planning And Adjustments For The Control Of Reach Extent In A Virtual Environment, Jill Campbell Stewart Pt,Phd, James Gordon, Carolee J. Winstein Mar 2013

Planning And Adjustments For The Control Of Reach Extent In A Virtual Environment, Jill Campbell Stewart Pt,Phd, James Gordon, Carolee J. Winstein

Faculty Publications

Background Skilled performance of reach actions includes both anticipatory planning and compensatory adjustments made while moving. The execution of reach actions in a virtual environment (VE) demonstrates similar characteristics to reaches performed in the real-world, however, it is unclear whether the VE itself significantly impacts movement planning or compensatory adjustments. The purpose of this study was to directly compare the use of planning and adjustments to control extent for unconstrained reach actions performed in an immersive VE to those performed in an analogous real-world environment (RWE). Methods Five non-disabled adults (29 ± 5 years) reached with the dominant, right arm …
