Ankle joint position sense acuity differences among stroke survivors at three walking ability levels: a cross-sectional study.

Background: Despite the importance of lower limb sensation in walking highlighted in systematic reviews, there is limited research investigating the effect of proprioceptive deficits after stroke and any relationship with walking ability.

Objectives: With stroke survivors of different walking ability, this study aimed to (1) explore side (affected/unaffected) and movement direction (inversion/plantar flexion) effects in ankle joint position sense (JPS) acuity, and (2) compare ankle JPS acuity between groups of stroke survivors with different walking ability.

Methods: Seventy subacute stroke survivors were recruited and divided into three groups based on walking ability, as determined by their gait speed on the 10-Meter Walking Test: household (<0.

Adaptive clinical trial of AZD7442 and SARS-CoV-2 vaccination in immunosuppressed patients highly vulnerable to infection with SARS-CoV-2 virus (RAPID-PROTECTION): protocol for a multicentre, interventional open-label, randomised controlled trial.

Introduction: Despite repeated vaccinations against SARS-CoV-2 virus, patients who are immunocompromised remain at very high risk of catching SARS-CoV-2 virus and becoming unwell. AZD7442 (Evusheld) is a long-acting monoclonal antibody treatment that has been shown in clinical trials to prevent SARS-CoV-2 infection for up to a year after a single dose. Vaccines require a healthy immune system to generate protective immunity.

Poorer objective but not subjective driving performance in drivers vulnerable to sleep loss effects during extended wake.

Sleepiness-related errors are a leading cause of driving accidents, requiring drivers to effectively monitor sleepiness levels. However, there are inter-individual differences in driving performance after sleep loss, with some showing poor driving performance while others show minimal impairment. This research explored if there are differences in self-reported sleepiness and driving performance in healthy drivers who exhibited vulnerability or resistance to objective driving impairment following extended wakefulness.

Proprioception After Unilateral Stroke: Changes in the Affected and Unaffected Lower Limbs Over Time.

Background: Proprioceptive deficits are common among stroke survivors and can negatively impact their balance and postural control. However, there has been little evaluation of the change in proprioceptive deficits in the lower limbs over time after stroke. This study aimed to examine proprioceptive deficits over time after stroke in both the affected and "unaffected" lower limbs.

TraitTrainR: accelerating large-scale simulation under models of continuous trait evolution.

Motivation: The scale and scope of comparative trait data are expanding at unprecedented rates, and recent advances in evolutionary modeling and simulation sometimes struggle to match this pace. Well-organized and flexible applications for conducting large-scale simulations of evolution hold promise in this context for understanding models and more so our ability to confidently estimate them with real trait data sampled from nature.

Results: We introduce , an R package designed to facilitate efficient, large-scale simulations under complex models of continuous trait evolution.
