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.

Complex Network Analysis of Surface Electromyography Shows Impaired Global Structure of Chronic Stroke Survivors with Hemiparesis

 

So you described a problem, offered NO SOLUTION. What the fuck good did this research do for solving all the problems in stroke? Useless assessment crapola like this should result in firings for everyone involved. I take no prisoners in trying to solve stroke.

Complex Network Analysis of Surface Electromyography Shows Impaired Global Structure of Chronic Stroke Survivors with Hemiparesis

Research Objectives

To investigate the use of high-density surface electromyography (EMG) and complex network analysis to quantify upper extremity motor impairment in chronic stroke survivors with hemiparesis. EMG can provide insights into the residual neuro-muscular activity during attempted functional movement. Using network analysis, we can determine how different muscle regions interact to create complex motion and the associated deficits after stroke.

Design

In three two-hour sessions, we led participants through attempted functional movements of the hand, fingers, and wrist while recording EMG activity using the NeuroLife® Sleeve, a 150-electrode wearable forearm garment.

Setting

Studies were conducted within Battelle's research facilities in Columbus, Ohio.

Participants

Six chronic stroke survivors (>6 months post-stroke) with moderate UE impairment (UEFM: 7-38).

Interventions

Not applicable.

Main Outcome Measures

Global efficiency and local clustering of the functional EMG networks. Global efficiency measures the ease of traversal of the network topology, with many regions in close coordination with each other showing increased efficiency. Local clustering measures the amount of electrode triads that appear in the network architecture, a measure of local microstructure.

Results

We find that network graphs from participants show differing topological structure that relates to the level of impairment of the participant. Specifically, participants with moderate to severe hand impairment had lower global network efficiency and local clustering when compared to mild-impairment participants or able-bodied controls. These results show that differences in network topology are sensitive to the pathophysiology that follows stroke.

Conclusions

Complex network analysis of surface EMG can provide a novel, quantifiable assessment of the extent of deficit in subjects with chronic stroke.
