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.

Predictive value of motor-evoked potentials for motor recovery in patients with hemiparesis secondary to acute ischemic stroke

I hate research with motor evoked potentials. It tells us nothing about how to get to actual recovery. Whatever prediction you get from these are useless unless they direct you to EXACT REHAB PROTOCOLS DELIVERING 100% RECOVERY!

Abstract

Background

Motor recovery following a stroke is related to the initial stroke severity and corticospinal tract integrity. One of the outcomes representing corticospinal tract integrity is the motor evoked potential (MEP). This study aimed to investigate the predictive value of MEP for motor recovery in patients with acute ischemic stroke.

Patients and Methods

Patients with hemiparesis secondary to initial acute ischemic stroke were enrolled. MEPs of the upper limb were assessed as preserved (MEP+) or absent (MEP-) response ≤10 days post-stroke. Fugl-Meyer assessment (FMA) was performed at baseline and post-stroke at 30 and 90 days. A modified Rankin scale (mRS) was conducted at 90 days post-stroke. Patients were divided into two groups according to the highest FMA score of MEP- patients. Generalized estimating equations and logistic regression were used for our study analysis.

Results

Sixty-one participants were included in this study. The highest FMA score of MEP- patients ≤10 days after stroke was 38. Among patients with an initial FMA score ≤38, FMA scores at 30 and 90 days post-stroke were significantly higher in MEP + patients than in MEP- patients. Proportional recovery at 30 and 90 days post-stroke was significantly higher in MEP + patients than in MEP- patients. MEP + patients had a higher percentage of good functional outcomes than MEP- patients, without statistical difference. Among patients with initial FMA score >38, FMA scores were 60.4 ± 4.8 and 63.9 ± 2.9 and proportional recovery was 65.2 ± 27.0% and 83.7 ± 24.6% at 30 and 90 days post-stroke, respectively.

Conclusions

Among patients with moderate-to-severe ischemic stroke, MEP + patients had better motor recoveries (approximately 70%) than MEP– patients at 90 days post-stroke. MEP + patients had better functional outcomes than MEP- patients.

  1. Key Messages

  2. Among patients with moderate-to-severe ischemic stroke, those with positive motor-evoked potentials (MEPs) had better motor recovery than those with negative MEPs at 90 days post-stroke.

  3. Assessment of motor-evoked potentials is a reliable method for predicting motor recovery in patients with moderate-to-severe ischemic stroke.

  4. Corticospinal tract function of patients with acute ischemic stroke was tested with transcranial magnetic stimulation.
