Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 13976 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. My back ground story is here:http://oc1dean.blogspot.com/2010/11/my-background-story_8.html

Sub-sensory vibratory noise augments the physiologic complexity of postural control in older adults
Postural control requires
numerous inputs interacting across multiple temporospatial scales. This
organization, evidenced by the “complexity” contained within standing
postural sway fluctuations, enables diverse system functionality.
Age-related reduction of foot-sole somatosensation reduces standing
postural sway complexity and diminishes the functionality of the
postural control system. Sub-sensory vibrations applied to the foot
soles reduce the speed and magnitude of sway and improve mobility in
older adults. We thus hypothesized that these vibration-induced
improvements to the functionality of the postural control system are
associated with an increase in the standing postural sway complexity.
Twelve healthy older adults
aged 74 ± 8 years completed three visits to test the effects of foot
sole vibrations at 0 % (i.e., no vibration), 70 and 85 % of the sensory
threshold. Postural sway was assessed during eyes-open and eyes-closed
standing. The complexity of sway time-series was quantified using
multiscale entropy. The timed up-and-go (TUG) was completed to assess
When standing without
vibration, participants with lower foot sole vibratory thresholds
(better sensation) had greater mediolateral (ML) sway complexity (r2 = 0.49, p < 0.001), and those with greater ML sway complexity had faster TUG times (better mobility) (r2 = 0.38, p
< 0.001). Foot sole vibrations at 70 and 85 % of sensory threshold
increased ML sway complexity during eyes-open and eyes-closed standing (p
< 0.0001). Importantly, these vibration-induced increases in
complexity correlated with improvements in the TUG test of mobility (r2 = 0.15 ~ 0.42, p < 0.001 ~ 0.03).
Sub-sensory foot sole
vibrations augment the postural control system functionality and such
beneficial effects are reflected in an increase in the physiologic
complexity of standing postural sway dynamics.
