Deans' stroke musings: Impairments in cognitive control using a reverse visually guided reaching task following stroke

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Impairments in cognitive control using a reverse visually guided reaching task following stroke

What the fuck good did this do in getting survivors recovered?

Abstract:

Study adapted a reverse reaching task to an interactive robotic platform to quantify impairments in cognitive-motor integration following stroke. Fifty-nine participants with subacute stroke performed two tasks using the Kinarm: Reverse Visually Guided Reaching (RVGR) and Visually Guided Reaching (VGR). Tasks required that subjects move a cursor “quickly and accurately” to virtual targets. In RVGR, cursor motion was reversed compared to finger motion (i.e., hand moves left, cursor moves right). Task parameters and task scores were calculated based on models developed from healthy controls, and accounted for the influence of age, sex, and handedness. Most stroke participants (86 percent) were impaired in RVGR with their affected arm. The most common impairment was increased movement time. Seventy-three percent were also impaired with their less-affected arm. The most common impairment was larger initial direction angles of reach. Impairments in RVGR improved over time, but 71 percent of participants tested longitudinally were still impaired with the affected arm about 6 months post-stroke. Importantly, although 57 percent were impaired with the less affected arm at 6 months, these individuals were not impaired in VGR. Overall, individuals with stroke were impaired in a reverse reaching task but many did not show similar impairments in a standard reaching task, highlighting selective impairment in cognitive-motor integration.
