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.

Neuromechanical Factors That Limit Walking Speed in Individuals with Post-Stroke Hemiparesis

I'm sure your doctor/therapist can apply any new information in here to your updated stroke walking protocol.

Abstract:
Individuals, post-stroke, present with an array of changes to the neuromuscular system function such as muscle weakness and abnormal muscle activation patterns. Different combinations of these and other altered body functions result in limitations in functional mobility, such as reduced gait speed and high risk for falls. In this series of studies, I developed a deeper understanding of how neuromechanical factors may limit the fastest speed that an individual post-stroke can reach before they are unable to move any faster without losing balance. I conducted three studies. In the first study, my results showed that, after stroke, individuals have the capacity to walk at faster speeds than their overground self-selected maximum walking speed, while walking on a treadmill and when provided horizontal assistance using a robotic device. In the second study, I showed that non-impaired individuals modulated the amplitude and phasing of muscle activity according to the requirements brought about by the existence of horizontal assistive forces during walking at progressively faster speeds. Finally, in the third study I showed that individuals post-stroke also were able to modulate amplitude and phasing of muscle activity in both legs, according to the requirements brought about by the existence of horizontal assistive forces during walking at progressively faster speeds. However, the paretic leg was more responsive to horizontal assistive forces than the non-paretic leg. The understanding gained through these studies provide novel insights regarding the capabilities of individuals with post-stroke hemiparesis to adapt their existing impaired neuromuscular mechanisms into more challenging walking tasks. Each study leads to ideas for the development of potentially more effective rehabilitation protocols targeted at the modulation of amplitude and phasing of muscle activity in order to safely achieve faster walking speeds.
