Deans' stroke musings: Investigating the feasibility and acceptability of real-time visual feedback in reducing compensatory motions during self-administered stroke rehabilitation exercises: A pilot study with chronic stroke survivors

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.

Investigating the feasibility and acceptability of real-time visual feedback in reducing compensatory motions during self-administered stroke rehabilitation exercises: A pilot study with chronic stroke survivors

So what if compensatory motions occur? If you were teaching a baby to walk they would never get there because you are expecting perfection every time. How many times do stroke survivors need to fail at a movement before the brain finally realizes it can control that movement? If you don't know the answer then just shut up and let survivors figure out the best way to move. Don't you learn faster from failures?

Investigating the feasibility and acceptability of real-time visual feedback in reducing compensatory motions during self-administered stroke rehabilitation exercises: A pilot study with chronic stroke survivors

Abstract

Introduction:Homework-based rehabilitation programs can help stroke survivors restore upper extremity function.However, compensatory motions can develop without therapist supervision, leading to sub-optimal recovery.We developed a visual feedback system using a live video feed or an avatar reflecting users’ movements so users are aware of compensations. This pilot study aimed to evaluate validity (how well the avatar characterizes different types ofcompensations) and acceptability of the system.
Methods:Ten participants with chronic stroke performed upper-extremity exercises under three feedback conditions:none, video, and avatar. Validity was evaluated by comparing agreement on compensations annotated using video andavatar images. A usability survey was administered to participants after the experiment to obtain information onacceptability.
Results:There was substantial agreement between video and avatar images for shoulder elevation and hip extension(Cohen’sk: 0.6–0.8) and almost perfect agreement for trunk rotation and flexion (k: 0.80–1). Acceptability was low due to lack of corrective prompts and occasional noise with the avatar display. Most participants suggested that an automatic compensation detection feature with visual and auditory cuing would improve the system.
Conclusion:The avatar characterized four types of compensations well. Future work will involve increasing sensitivity for shoulder elevation and implementing a method to detect compensations.
