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.

Automatic Detection of Compensation during Robotic Stroke Rehabilitation Therapy

I would have to disagree on the compensation leading to undesirable rehabilitation outcomes. It may just be a stepping stone to recovery. I wouldn't be walking anywhere if I had to walk perfectly, with my compensation of swinging my leg like a log I can easily get in 10,000 steps a day.  This also points out once again the insistence on perfect movements, rather than you learning faster by error-based learning.
Also the therapist pushed perfectionism that Peter Levine writes about in  Movement elitism.
At least you can tell your therapist they don't know what they are doing, with robots it is kinda hard to get through to them. This example of voice activated elevator in Scotland is instructive. 


Automatic Detection of Compensation during Robotic Stroke Rehabilitation Therapy








Abstract:
Robotic stroke rehabilitation therapy can greatly increase the efficiency of therapy delivery. However, when left unsupervised, users often compensate for limitations in affected muscles and joints by recruiting unaffected muscles and joints, leading to undesirable rehabilitation outcomes. This study aims to develop a computer vision system that augments robotic stroke rehabilitation therapy by automatically detecting such compensatory motions. Nine stroke survivors and ten healthy adults participated in this study. All participants completed scripted motions using a table-top rehabilitation robot. The healthy participants also simulated three types of compensatory motions. The 3-D trajectories of upper body joint positions tracked over time were used for multiclass classification of postures. A Support Vector Machine (SVM) classifier detected lean-forward compensation from healthy participants with excellent accuracy (AUC=0.98, F1=0.82), followed by trunk-rotation compensation (AUC=0.77, F1=0.57). Shoulder-elevation compensation was not well detected (AUC=0.66, F1=0.07). A Recurrent Neural Network classifier (RNN), which encodes the temporal dependency of video frames, obtained similar results. In contrast, F1- scores in stroke survivors were low for all three compensations while using RNN: lean-forward compensation (AUC =0.77, F1=0.17), trunk-rotation compensation (AUC =0.81, F1=0.27), shoulder-elevation compensation (AUC =0.27, F1=0.07). The result was similar while using SVM. To improve detection accuracy for stroke survivors, future work should focus on predefining the range of motion, direct camera placement, delivering exercise intensity tantamount to that of real stroke therapies, adjusting seat height, and recording full therapy sessions.
