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

Rehabilitation of hemineglect of the left arm using movement detection bracelets activating a visual and acoustic alarm
Hemineglect is frequent after
right hemisphere stroke and prevents functional independence, but
effective rehabilitation interventions are lacking. Our objective was
to determine if a visual-acoustic alarm in the hemineglect arm activated
by a certain discrepancy in movement of both hands can enhance neglect
arm use in five tasks of daily living.
In this pre-post intervention
study 9 stroke patients with residual hemineglect of the arm were
trained for 7 days in five bimanual tasks of daily living: carrying a
tray, button fastening, cutting food with knife and fork, washing the
face with both hands and arm sway while walking. This was done through
motion sensors mounted in bracelets on both wrists that compared
movement between them. When the neglect-hand movement was less than a
limit established by two fuzzy logic based classifiers, a
visual-acoustic alarm in the neglect-hand bracelet was activated to
encourage its use in the task.
Both motion and function of
the neglect hand improved during the seven days of training when
visual-acoustic alarms were active but a worsening to baseline values
occurred on day 8 and day 30 when alarms where switched off. Improvement
was limited to vision-dependent tasks. (Well then, write up a protocol on what works.)
Neglect-hand improvement with
this approach is limited to bimanual activities in which an object is
manipulated under vision control, but no short or long term learning
Hemisensory neglectNeglect rehabilitationFuzzy logicActivities of daily livingMedical device
visual-spatial hemineglect (also known as hemi-inattention) patients
with a lesion of the right cerebral hemisphere are not aware of objects
in the left visual field despite not having a visual deficit. When it
encompasses left limbs, as well as lacking awareness of them, the
patient does not use the left arm in spite of not having paralysis.
Neglect predicts not regaining functional independence .
In more than 85 % of patients with right hemispheric stroke,
hemineglect is found in at least one pencil and paper tests such as
cancellation of lines and marking lines in their middle point, copy of
superimposed shapes or of a figurative drawing. But in 36 % of cases,
neglect in activities of daily living cannot be detected by these tests . Among the 28 standardized tests for hemineglect ,
the Catherine Bergego scale is one of the most used and asks about
performance of the patient in activities of daily living but does not
measure the performance itself. Several rehabilitation strategies for
hemineglect have been used [4, 5]
including forced visual sweep scanning, trunk rotation, application of
muscle vibration in the neck, mental images, visual prisms, sensory
activation of the left arm , vestibular stimulation on the left side, and transcranial magnetic stimulation .
Currently, there is insufficient evidence to recommend a particular
rehabilitation strategy for neglect as shown by a Cochrane review that
found no efficacy of rehabilitation interventions in reducing disability
In this pre-post intervention pilot study, we studied if a
visual-acoustic alarm in the hemineglect arm activated by its reduced
movement relative to the contralateral arm could increase neglect arm
use in five tasks of daily living. To monitor arm movement, we used
triaxial accelerometers, previously employed to measure upper limb
movement after stroke [10, 11].
