Ask your doctor if this would help your hand spasticity and when it will be available for your rehab use. Don't allow any hemming or hawing, your doctor has to be pinned down to deliver a specific action. Curing your hand spasticity, NOTHING LESS.
Robotic Hand Exoskeleton With Tactile Force Feedback For Post-Stroke Spasticity Rehabilitation
Abstract:
Spasticity
is a common complication that occurs in post-stroke patients that
refers to stiff muscles. Post-Stroke patients with spasticity can cause a
lack of ability to grasp object. Repetition of specific-task practice,
such as grasping and lifting a cup, can help the recovery of spasticity.
After various physiotherapy techniques to treat spasticity on the hand,
it is necessary to evaluate the strength of the patient's hands during
grasping. Rehabilitation technology, including exoskeleton, are being
developed to enhance hand function in patients with spasticity. Although
there are many task spesific practice method with exoskeleton, to get a
measurement of force during grasp interactions is still challenging.
The purpose of this study is to develop a hand exoskeleton with feedback
from tactile sensor to measure contact force distribution at patient's
rmgertips during grasp movement, then external power from the
exoskeleton helps subjects maintain grip strength. The external power is
determined based on the measured contact force distribution value using
the tactile sensor and it is value compared with the threshold obtained
based on experiment. The normal hand grip threshold measurement
obtained for lifting a cup was 2.254 N. During rehabilitation, subjects
were hold and lift a cup 10 times. It was found the timing of fatigue
during experiments on subjects 1, 2, 4 and 5 respectively occurred in
the 9th, 10th, 8th and 9th tests. Furthermore, exoskeleton can maintain
the strength of the grasp around the threshold by giving external power
stimulus if the contact force measurement were detected below the
threshold. As a result, in the whole test before fatigue appeared, the
total average value of the grasp was above the threshold.
