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.

Walking with robot‑generated haptic forces in a virtual environment: A new approach to analyze lower limb coordination

Lots of big words, hope you can figure it out.

Abstract: Study evaluated the extent of kinematic changes in bilateral lower limb coordination in response to continuous haptic tensile forces applied to the hand. Fourteen participants with chronic stroke were stratified based on overground gait speed into lower functioning (< 0.8 m/s) and higher functioning (≥ 0.8 m/s) subgroups. These subgroups and 14 age-matched control subjects walked on a self-paced treadmill in a virtual environment with either robot-generated haptic leash forces delivered to the hand and then released or with an instrumented cane. Walking in both leash (10 and 15 newtons) and cane conditions were compared to pre-force baseline values to evaluate changes in lower-limb coordination outcomes. All groups showed some kinematic changes in thigh, leg, and foot segments when gait speed increased during force and post-force leash as well as cane walking. These changes were also reflected in intersegmental coordination and three-dimensional phase diagrams, which illustrated increased intersegmental trajectory areas and angular velocity. These increases could also be observed when the paretic leg transitions from stance to swing phases while walking with the haptic leash. The Sobolev norm values accounted for both angular position and angular velocity, providing a single value for potentially quantifying bilateral (i.e., non-paretic vs paretic) coordination during walking. These values tended to increase proportionally for both limbs during force and post-force epochs as gait speed tended to increase.
