Significant clinician training is required to mitigate the subjective nature and achieve useful reliability between measurement occasions therapists. Previous research supports that robotic instruments can improve quantitative biomechanical assessments of upper limb, offering reliable more sensitive measures. Furthermore, combining kinematic kinetic measurements with electrophysiological offers new insights unlock targeted impairment-specific therapy.

While many areas of medicine have benefited from the development objective assessment tools and biomarkers, there been comparatively few improvements in techniques used to assess brain function dysfunction. Brain functions such as perception, cognition, motor control are commonly measured using criteria-based, ordinal scales which can be coarse, floor/ceiling effects, often lack precision detect change. There is growing recognition that kinematic kinetic-based measures needed quantify impairments following neurological injury stroke, particular for clinical research trials. This paper will first consider challenges with criteria-based impairment recovery. We then describe how kinematic-based overcome these highlight a statistical approach behavior based on performance neurologically healthy individuals. illustrate this visually-guided reaching task individuals stroke.

Proprioceptive impairments occur in ~50% of stroke survivors, with 20-40% still impaired six months post-stroke. Early identification those likely to have persistent is key personalizing rehabilitation strategies and reducing long-term proprioceptive impairments. In this study, clinical, neuroimaging robotic measures were used predict at post-stroke on a assessment proprioception. Clinical assessments, neuroimaging, arm position matching (APM) task performed for 133 participants two weeks (12.4 ± 8.4 days).

Evaluating neurological impairments post-stroke is essential for assessing treatment efficacy and managing subsequent disabilities. Conventional clinical assessment methods depend largely on clinicians' visual physical evaluations, resulting in coarse rating systems that frequently miss subtle or improvements. Interactive robotic devices, like the Kinarm Exoskeleton system, are transforming of motor by offering precise objective movement measurements. In this study, we analyzed kinematic data from 337 stroke patients 368 healthy controls performing three tasks. Using deep learning methods, particularly an evidential network, distinguished impaired participants while generating measures prediction uncertainty. By retraining network with least uncertain samples refining test set excluding top 10% most samples, improved sensitivity detecting minimally (those scoring normal CMSA) 0.55 to 0.75. We further extended model detect associated transient ischemic attack (TIA), increased detection accuracy 0.86 0.92. The model's ability identify deficits, even TIA who show no observable symptoms standard exams, highlights its significant utility. Detecting critical, as individuals experience a have substantially higher risk recurrent stroke. This work immense potential integrating uncertainty estimation enhance stroke-related impairments, potentially paving way personalized rehabilitation.

Abstract Background Proprioceptive impairments are common after stroke and associated with worse motor recovery poor rehabilitation outcomes. Motor learning may also be an important factor in recovery, some evidence healthy adults suggests that reduced proprioceptive function is reductions learning.
