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.

Cathodal Transcranial Direct Current Stimulation in Acute Ischemic Stroke: Pilot Randomized Controlled Trial

Now we need human testing which your doctors and stroke hospital will do nothing to initiate.

Cathodal Transcranial Direct Current Stimulation in Acute Ischemic Stroke: Pilot Randomized Controlled Trial

Originally publishedhttps://doi.org/10.1161/STROKEAHA.120.032056Stroke. 2021;52:1951–1960

Background and Purpose:

In acute stroke, preventing infarct growth until complete recanalization occurs is a promising approach as an adjunct to reperfusion therapies to reduce infarct size and improve outcome. In rodent models, cathodal transcranial direct current stimulation (C-tDCS) decreases peri-infarct depolarizations and reduces infarct volume. We hypothesized that C-tDCS would nonpharmacologically reduce infarct growth in hyperacute middle cerebral artery territory stroke patients receiving reperfusion therapy.

Methods:

STICA (Cathodal Transcranial Direct Stimulation in Acute Middle Cerebral Artery Stroke) was a pilot single-center, double-blind, 2-arms 1:1 randomized trial evaluating the safety, feasibility, and efficacy of C-tDCS versus sham stimulation in patients eligible for recanalization therapies. Magnetic resonance imaging was obtained both on admission and 24 hours later. The primary end point was 24-hour infarct growth. Secondary outcomes were (1) National Institutes of Health Stroke Scale score difference between day 7 and admission and (2) 3-month modified Rankin Scale score.

Results:

Forty-five patients were randomized. Median magnetic resonance imaging-to-C-tDCS start time was 45 minutes; C-tDCS was started before completion of recanalization procedure in all patients. The intervention proved feasible in all patients. No major adverse effects occurred in either group. There was no significant difference between active and sham groups for any end point. However, an apparent trend towards smaller infarct growth in the C-tDCS arm was observed in the whole group (unadjusted median difference [IC95%]: −2.2 mL [−12.2 to 1.5]) and in the prespecified subsamples with moderate-to-severe stroke and large vessel occlusion (−5.7 mL [−21.6 to 2.6] and −7.7 mL [−24.2 to 2.6], respectively).

Conclusions:

C-tDCS was feasible and well tolerated. No significant difference was found between the active and sham groups. However, the data suggest potential benefits of C-tDCS in patients with National Institutes of Health Stroke Scale score of >10 or large vessel occlusion. Using the observed effect size and standard α=5% and β=20%, samples of 102 and 86, respectively, can be estimated for future trials in patients with these characteristics. Randomized trials particularly targeting these populations may be warranted.
