Finally maybe some objective measurements rather than gut feel. I estimate 25 years before it becomes common usage.

In this study, we investigated the structural plasticity of the
contralesional motor network in ischemic stroke patients using diffusion
magnetic resonance imaging (MRI) and explored a model that combines a
MRI-based metric of contralesional network integrity and clinical data
to predict functional outcome at 6 months after stroke.MRI and clinical
examinations were performed in 12 patients in the acute phase, at 1 and 6
months after stroke. Twelve age- and gender-matched controls underwent 2
MRIs 1 month apart. Structural remodeling after stroke was assessed
using diffusion MRI with an automated measurement of generalized
fractional anisotropy (GFA), which was calculated along connections
between contralesional cortical motor areas. The predictive model of
poststroke functional outcome was computed using a linear regression of
acute GFA measures and the clinical assessment.GFA changes in the
contralesional motor tracts were found in all patients and differed
significantly from controls (0.001 ≤ p < 0.05). GFA changes in
intrahemispheric and interhemispheric motor tracts correlated with age
(p ≤ 0.01); those in intrahemispheric motor tracts correlated strongly
with clinical scores and stroke sizes (p ≤ 0.001). GFA measured in the
acute phase together with a routine motor score and age were a strong
predictor of motor outcome at 6 months (r(2) = 0.96, p = 0.0002).These
findings represent a proof of principle that contralesional diffusion
MRI measures may provide reliable information for personalized
rehabilitation planning after ischemic motor stroke. Neurology®

Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 28,972 posts. Searching is done in the search box in upper left corner. I blog on anything to do with stroke.DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER, BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
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.
