Deans' stroke musings: Human Cognition-Based Power-Assisted Free Motion Object Manipulation for Automating Upper Arm Stroke Rehabilitation

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.

Human Cognition-Based Power-Assisted Free Motion Object Manipulation for Automating Upper Arm Stroke Rehabilitation

Only one question. Will it deliver 100% recovery? The only goal in stroke! NO? then redesign it until it does!

Human Cognition-Based Power-Assisted Free Motion Object Manipulation for Automating Upper Arm Stroke Rehabilitation

Abstract:

We proposed a 1DOF power assist robotic system to be used by stroke patients for upper arm stroke rehabilitation. An object is tied with the power assist robotic system so a human patient can lift it vertically up and lower it down continuously for a long time for rehabilitation practice. The power assist robotic system is designed to provide power assistance to the patient in lifting and lowering the object. The amount of power assistance can be changed that can change haptically perceived weight or heaviness of the object and vice versa. As a result, the stroke patient can adjust the perceived weight or heaviness of the object at different stages of rehabilitation practices considering the strength and ability of the patient to lift and lower the object with the power assist system at different stages of rehabilitation progress. We derived a computational model to compute power assistance levels of the assist system. We applied a psychophysical method to determine power assistance levels for different perceived weights or heaviness of the manipulated object. We conducted an experiment to evaluate the performance of the power assist robotic system based on an innovative evaluation scheme using healthy human subjects. The results revealed that the subjects were able to realize the variations in the power assistance levels due to variations in the perceived weights or heaviness of the manipulated object. A user study results demonstrated satisfactory user interactions with the power assist robotic system. The proposed approach and mechanism can help automate upper arm rehabilitation of stroke patients, which can improve the quality of life (QoL) of patients.
