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.

Stepping towards independence: a creative low-cost robotic ankle-foot mechanism for post-stroke rehabilitation

 What does your doctor currently have for your ankle rehab?

Abstract: This paper presents a robotic ankle-foot system for post-stroke rehabilitation, addressing ankle-joint issues in stroke patients. The system interfaces with MATLAB mobile sensors and consists of two key components: a basic robotic platform and a control system with a shared microcontroller and two IR sensor modules for angle adjustment limits. The mechanical construction utilises plain carbon steel SAE 1030 due to its strength properties. Computer simulations were used to validate the technique, focusing on angular velocity as a key parameter. Analysis of passive/active joint parameters showed significant improvements, with maximal dorsiflexion/plantarflexion angles increasing from 12.0 to 28.0 degrees and 20.5 to 27.0 degrees. This system effectively reduces ankle spasticity(I like this) and contracture, offering a viable clinical rehabilitation option. Mathematical models for stress, strain, displacement, and safety factor were provided with strong correlation. Promising results have prompted further testing on real stroke survivors and exploration of lightweight, weight-bearing materials for future research.
