Finally someone looking at the specific problems with stroke movements.

Abstract—Previous studies using robotic devices that focus on
the wrist/fingers following stroke provide an incomplete picture of
movement dysfunction because they do not consider the abnormal
joint torque coupling that occurs during progressive shoulder abduction
loading in the paretic upper limb. This letter introduces a
device designed to measure isometric flexion/extension forces generated
by the fingers, wrist, and thumb during robot-mediated 3-D
dynamic movements of the upper limb. Validation data collected
from eight participants with chronic hemiparetic stroke are presented
in this paper.
Index Terms—Hand, kinetic measurements, robotic rehabilitation,
shoulder loading, stroke, upper extremity.
I. INTRODUCTION
IN RECENT years, the quest for more effective rehabilitation
strategies for the upper limb following hemiparetic stroke has
focused on employing instrumented robotic devices to explore
motor learning, to investigate the effects of treatment intensity,
and to study mechanisms underlying stroke-induced movement
disorders. This letter introduces a device, theWrist/Finger Force
Sensing module (WFFS), which is designed to quantify potential
abnormal joint torque coupling between the shoulder and
wrist/fingers in the paretic upper limb. The WFFS measures
isometric flexion/extension forces generated by the wrist, fingers,
and thumb during 3-D movements of the paretic upper
limb.
In the paretic upper limb of moderately to severely affected
hemiparetic stroke survivors, coupling between shoulder abductors
and elbow, wrist and finger flexors, clinically described
as the flexion synergy [1], [2], frequently occurs. This coupling
could partially explain the hypertonia in the wrist/finger
flexors observed frequently during upper limb movements following
stroke. Robotic assistive devices for the hand, such as
extension-aiding gloves and exoskeletons, have the potential to
improve hand function, as do robot-aided rehabilitation protocols
that can involve sophisticated and precise active or passive
mechanical manipulations of the hand/wrist. However, the expression
of the stroke-induced flexion synergy at the hand must
be better quantified before these technologies can reach their
full potential.
Currently available robot assistive devices or robot-aided rehabilitation
protocols for the hand and wrist are limited because
they have examined the hand and wrist in isolation from the
rest of the upper limb. Devices such as CyberGrasp exoskeleton
(CyberGlove Systems), HandCARE [3], RutgersMasters II [4],
Hand–Wrist Assisting Robotic Device (HWARD) [5], Multiple
User Virtual Environment for Rehabilitation (MUVER) [6],
and other pneumatically controlled or actuated gloves [7], [8]
are generally designed to assist hand opening, increase finger
range of motion, or improve object grasp/release. Other devices,
like the Haptic Knob [9], are designed to improve performance
of functional tasks that require precise fine motor control.
Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 29,116 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.
Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 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:
My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. 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 lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.
