Metaverse technologies in acute care medical education: A scoping review.
AEM Educ Train
February 2025
Michael G. DeGroote School of Medicine, Faculty of Health Sciences McMaster University Hamilton Ontario Canada.
Background: The concept of the metaverse is a virtual world that immerses users, allowing them to interact with the digital environment. Due to metaverse's utility in collaborative and immersive simulation, it can be advantageous for medical education in high-stakes care settings such as emergency, critical, and acute care. Consequently, there has been a growth in educational metaverse use, which has yet to be characterized alongside other simulation modalities literature.

Background: This study aims to compare design, phase transformation behavior, and torsional resistance of the ProGlider (PG) and ProTaper ultimate slider (PUS) and to compare the performance of two files in the glide-path preparation of a double-curved artificial canal.
Methods: Scanning electron microscopy, micro-computed tomography, and differential scanning calorimetry were used to characterize the samples. A torsional resistance test was performed to obtain ultimate strength and distortion angle.

Quantitative assessment for post-stroke spasticity remains a significant challenge due to the encountered variable resistance during passive stretching, which can lead to the widely used modified Ashworth scale (MAS) for spasticity assessment depending heavily on rehabilitation physicians. To address these challenges, a high-force-output triboelectric soft pneumatic actuator (TENG-SPA) inspired by a lobster tail is developed. The bioinspired TENG-SPA can generate approximately 20 N at 0.

Investigating the physiological mechanisms in the motor cortex during rehabilitation exercises is crucial for assessing stroke patients' progress. This study developed a single-channel Jansen neural mass model to explore the relationship between model parameters and motor cortex mechanisms. Firstly, EEG signals were recorded from 11 healthy participants under 20%, 40%, and 60% maximum voluntary contraction, and alpha rhythm power spectral density characteristics were extracted using the Welch power spectrum method.

The wings of birds contain complex morphing mechanisms that enable them to perform remarkable aerial maneuvers. Wing morphing is often described using five wingbeat motion parameters: flapping, bending, folding, sweeping, and twisting. However, owing to a lack of real bird flight data, in-depth studies on the aerodynamic properties of these coupled motions remain scarce.
