Towards an Optimal Model of Post-Stroke Sensorimotor Control.
Article in IEEE ... International Conference on Rehabilitation Robotics : [proceedings], 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
After stroke, motor control deficits are a common cause of disability. An optimal control model could provide insight into how motor and cognitive impairments influence post-stroke sensorimotor control. We present an initial attempt at modeling how post-stroke individuals perform a robot-based preview tracking task. Specifically, we fit a feedback controller with added delay and position bias to the impaired and less-impaired limbs of 11 stroke patients. We use an inverse linear quadratic regulator (LQR) to find the cost function for each participant. We also use linear regression to determine relationships between model parameters and clinical assessments of motor and cognitive impairments. Our main findings are that post-stroke sensorimotor control can be modeled as an optimal feedback controller and adding a delay and bias constant may improve the performance of this model. We also comment on how model parameters may be related to clinical assessments via linear regression. Future work should model more individuals and evaluate kinematic performance.
