I bet your doctor and stroke hospital have done absolutely NOTHING with these 23 earlier posts on haptics back to March 2011. More incompetency in action.
Abstract
This paper evaluates the prospects of using a novel
Integrated
Haptic Feedback
IHF
)
system. IHF can
provide
over
-
ground gait training
regimens
for post
-
stroke ambulatory
subjects.
IHF
system combines the use of a portable
cane for
kinesthetic
feedback
and a wearable vibrotactor array for
tac
tile
feedback.
Continuous s
omatosensory input is afforded to
the users at
the handle
of cane;
it serves the purpose of balance
assurance
at higher gait speeds. Besides, restricted use o
f upper
limb
for weight
-
bearing
inspires the users to involve the paretic
lower limbs more actively. Furthermore, tactile feedback
contribute
s
in enhancing the gait
symmetry
through afferent
signal of vibration.
Six post
-
stroke ambulatory individuals
participated in walking trials to identify the effects of IHF
system. Results
indicate
that while walking faster patients
’ body
sway was not disturbed.
S
tatistically
significant
increase
was
observed in temporal stance symmetry (p
-
value
=0.02) and
in
paretic
mus
cle
(vastus medialis obliquus and
semitendinosus
)
activation
during stance
phase
(

value
.
The IHF syst
em
can be a valuable tool to assist physical therapist in gait
rehabilitation of post
-
stroke individuals.
