This is only useful if the measurements point to EXACT PROTOCOLS THAT DELIVER RECOVERY FROM THIS! Otherwise this is totally fucking useless! I'd fire everyone involved for incompetence.
Measuring Arm and Hand Joint Kinematics to Estimate Impairment During a Functional Reach and Grasp Task after Stroke
Abstract
Background
Current
approaches to characterizing deficits in upper limb movements after
stroke typically focus either on changes in a functional measure, for
example, how well a patient can complete a task, or changes in
impairment, for example, isolated measurements of joint range of motion.
However, there can be notable dissociations between static measures of
impairment versus those of function.
Objective
We
develop a method to measure upper limb joint angles during performance
of a functional task and use measurements to characterize joint
impairment in the context of a functional task.
Methods
We
developed a sensorized glove that can precisely measure select finger,
hand, and arm joints while participants complete a functional
reach-to-grasp task involving manipulation of a sensorized object.
Results
We
first characterized the accuracy and precision of the glove’s joint
angle measurements. We then measured joint angles in neurologically
intact participants (n = 4 participants, 8 limbs) to define the expected
distribution of joint angle variation during task execution. These
distributions were used to normalize finger, hand, and arm joint angles
in stroke participants (n = 6) as they performed the task. We present a
participant-specific visualization of functional joint angle variance
which illustrated that stroke participants with nearly identical
clinical scores exhibited unique patterns of joint angle variation.
Conclusions
Overall,
measuring individual joint angles in the context of a functional task
may inform whether changes in functional scores over recovery or
rehabilitation are driven by changes in impairment or the development of
compensatory strategies, and provide a quantified path toward
personalized rehabilitative therapy.
