Motor inhibition during voluntary gait initiation in young and older adults.

Based on a novel approach, this study explores feasibility and relevance of an inhibition task for studying age-related differences in motor inhibition during gait initiation. When presented with a go-signal, young adults (YA, n = 24) and older adults (OA, n = 55) were required to promptly initiate gait. Participants completed 3 blocks of 12 gait trials.

Predicting periprosthetic joint infection: external validation of preoperative prediction models.

: Prediction models for periprosthetic joint infections (PJIs) are gaining interest due to their potential to improve clinical decision-making. However, their external validity across various settings remains uncertain. This study aimed to externally validate promising preoperative PJI prediction models in a recent multinational European cohort.

What Is the Most Optimal Bearing Surface for Minimizing Instability After Revision Total Hip Arthroplasty?

Based on the results of our meta-analysis, dual mobility implants appear to have the most efficacy in preventing instability following revision total hip arthroplasty. Notwithstanding, given the relatively small sample sizes of the included studies, in conjunction with heterogeneity in study design, it is important to recognize that further large randomized controlled trials are necessary to determine the optimal bearing surface to reduce the risk of instability after revision total hip arthroplasty.

Circadian disturbances, anxiety and motor disturbances differentiate delirium superimposed on dementia from dementia-only.

Background: To ensure adequate treatment, individuals with delirium superimposed on dementia (DSD) need to be differentiated reliably from those with dementia only (DO). Therefore, we aimed to examine the clinical indicators of DSD by assessing motor subtypes, cognitive performance and neuropsychiatric symptoms in DSD and DO patients.

Methods: Cross-sectional design with the Delirium-Motor-Subtyping Scale (DMSS), Mini-Mental-State-Examination (MMSE), Clock-Drawing-Test (CDT), DemTect, and Neuropsychiatric Inventory assessed after admission to an acute hospital.

Age-related effects of immediate and delayed task switching in a targeted stepping task.

The ability to quickly adapt steps while walking is pivotal for safe mobility. In a previous study of immediate switching between the two stepping tasks, older adults (OAs) performed worse than young adults (YAs). However, it remained unclear whether this difference was due to an inability to learn the tasks or an inability to quickly switch.
