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.

Targeting interhemispheric inhibition with neuromodulation to enhance stroke rehabilitation

 

 In my case there is no interhemispheric inhibition since it is dead brain over there. Their zone of inhibition looks like the penumbra where you have damaged neurons not working that well.  I'm sure that most of my neurons in the penumbra died since ABSOLUTELY NOTHING WAS DONE TO SAVE THEM!

So what is your dead brain rehab protocol? There must be millions of us out there and I've never seen any research on that problem.

abstract 

 
Background/Objectives:  
 
Interhemispheric inhibition in the brain plays a dynamic role in the production of voluntary unimanual actions. In stroke, the interhemispheric imbalance model predicts the presence of asymmetry in interhemispheric inhibition, with excessive inhibition from the contralesional hemisphere limiting maximal recovery. Stimulation methods to reduce this asymmetry in the brain may be promising as a stroke therapy, however determining how to best measure and modulate interhemispheric inhibition and who is likely to benet, remain important questions.  
 
Methods:
This review addresses current understanding of interhemispheric inhibition in the healthy and stroke lesioned brain. We present a review of studies that have measured interhemispheric inhibition using different paradigms in the clinic, as well as results from recent animal studies investigating stimulation methods to target abnormal inhibition after stroke.  
 
Main ndings/Discussion: 
 
The degree to which asymmetric interhemispheric inhibition impacts on stroke recovery is controversial, and we consider sources of variation between studies which may contribute to this debate. We suggest that interhemispheric inhibition is not static following stroke in terms of the movement phase in which it is aberrantly engaged. Instead it may be dynamically increased onto perilesional areas during early movement, thus impairing motor initiation. Hence, its effect on stroke recovery may differ between studies depending on the technique and movement phase of eliciting the measurement. Finally, we propose how modulating excitability in the brain through more specic targeting of neural elements underlying interhemispheric inhibition via stimulation type, location and intensity may raise the ceiling of recovery following stroke and enhance functional return. © 2017 Elsevier Inc.

The interhemispheric imbalance model predicts that each side of the brain inhibits the other equally. After a stroke, the inhibition coming from the stroke- affected hemisphere is decreased (interhemispheric dashed line) alongside a decreased excitability in the peri-lesional tissue. The unaffected hemisphere therefore becomes more excitable and exerts a stronger inhibition onto the peri-lesional tissue. Modulating this zone of inhibition in the peri-infarct tissue appears to be a potential target for stroke therapy.
