Deans' stroke musings

Changing stroke rehab and research worldwide now.Time is Brain!Just think of all the trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 493 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:

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's quite disgusting that this information is not available from every stroke association and doctors group.

Skilled Reach Performance Correlates With Corpus Callosum Structural Integrity in Individuals With Mild Motor Impairment After Stroke: A Preliminary Investigation

I bet my inability to do any kind of reaching is due to spasticity. This research was useless in helping survivors get better, more followup needed. Next steps is missing, how would you go about solving the problem you describe?

Background. Recovery of arm function after stroke is often incomplete. An improved understanding of brain structure–motor behavior relationships is needed for the development of novel and targeted rehabilitation interventions. Objective. To examine the relationship between skilled reach performance and the integrity of two putative white matter motor pathways, corticospinal tract and corpus callosum, after stroke. Methods. Eleven individuals with chronic stroke (poststroke duration, mean 62.5 ± 42.4 months) and mild motor impairment (upper extremity Fugl-Meyer score, mean 54.2 ± 7.6) reached to six targets presented at three distances and two directions. Fractional anisotropy (FA) obtained from diffusion tensor imaging was used to determine the structural integrity of the corticospinal tract and the corpus callosum. Results. Overall reach performance was decreased in the paretic arm compared with the nonparetic arm. While FA was decreased in the ipsilesional corticospinal tract, FA in the corticospinal tract did not correlate with variability in reach performance between individuals. Instead, FA in the premotor section of the corpus callosum correlated with reach performance; individuals with higher FA in premotor corpus callosum tended to reach faster with both the paretic and nonparetic arms. Conclusions. The structural connections between the two premotor and supplemental cortices that traverse the premotor corpus callosum may play an important role in supporting motor control and could become a target for interventions aimed at improved arm function in this population.
