Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 12874 posts. Searching is done in the search box in upper left corner. I blog on anything to do with stroke.DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER, BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
Deans' stroke musings
Changing stroke rehab and research worldwide now.Time is Brain!Just think of all thetrillions and trillions of neuronsthateach daybecause there areeffective hyperacute therapies besides tPA(only 12% effective). I have 493 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:
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's quite disgusting that this information is not available from every stroke association and doctors group.

Principal component analysis for ataxic gait using a triaxial accelerometer
It is quite difficult to
evaluate ataxic gait quantitatively in clinical practice. The aim of
this study was to analyze the characteristics of ataxic gait using a
triaxial accelerometer and to develop a novel biomarker of integrated
gate parameters for ataxic gait.
Sixty-one patients with
spinocerebellar ataxia (SCA) or multiple system atrophy with predominant
cerebellar ataxia (MSA-C) and 57 healthy control subjects were
enrolled. The subjects were instructed to walk 10 m for a total of 12
times on a flat floor at their usual walking speed with a triaxial
accelerometer attached to their back. Gait velocity, cadence, step
length, step regularity, step symmetry, and degree of body sway were
evaluated. Principal component analysis (PCA) was used to analyze the
multivariate gait parameters. The Scale for the Assessment and Rating of
Ataxia (SARA) was evaluated on the same day of the 10-m walk trial.
PCA divided the gait
parameters into four principal components in the controls and into two
principal components in the patients. The four principal components in
the controls were similar to those found in earlier studies. The second
principal component in the patients had relevant factor loading values
for gait velocity, step length, regularity, and symmetry in addition to
the degree of body sway in the medio-lateral direction. The second
principal component score (PCS) in the patients was significantly
correlated with disease duration and the SARA score of gait (ρ = −0.363, p = 0.004; ρ = −0.574, p < 0.001, respectively).
PCA revealed the main
component of ataxic gait. The PCS of the main component was
significantly different between the patients and controls, and it was
well correlated with disease duration and the SARA score of gait in the
patients. We propose that this score provides a novel method to assess
the severity of ataxic gait quantitatively using a triaxial
