Something was suggested here but obviously they couldn't elucidate it for survivors to bring to their therapists to implement. Useless.
The Impact of Cognitive Impairment on Robot-Based Upper-Limb Motor Assessment in Chronic Stroke
Abstract
Background
Chronic
upper extremity motor deficits are present in up to 65% of stroke
survivors, and cognitive impairment is prevalent in 46-61% of stroke
survivors even 10 years after their stroke. Robot-assisted therapy
programs tend to focus on motor recovery and do not include stroke
patients with cognitive impairment.
Objective
This
study aims to investigate performance on the individual cognitive
domains evaluated in the MoCA and their relation to upper-limb motor
performance on a robotic system.
Methods
Participants
were recruited from the stroke population with a wide range of
cognitive and motor levels to complete a trajectory tracking task using
the Haptic TheraDrive rehabilitation robot system. Motor performance was
evaluated against standard clinical cognitive and motor assessments.
Our hypothesis is that the cognitive domains involved in the visuomotor
tracking task are significant predictors of performance on the
robot-based task and that impairment in these domains results in worse
motor performance on the task compared to subjects with no cognitive
impairment.
Results
Our
results support the hypothesis that visuospatial and executive function
have a significant impact on motor performance, with differences
emerging between different functional groups on the various robot-based
metrics. We also show that the kinematic metrics from this task
differentiate cognitive-motor functional groups differently.
Conclusion
This
study demonstrates that performance on a motor-based robotic assessment
task also involves a significant visuospatial and executive function
component and highlights the need to account for cognitive impairment in
the assessment of motor performance.
