Artificial structures for human‐machine interfaces with closed‐loop interaction

FlexMat, EarlyView.
Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...

Point‐Of‐Care Ultrasound for the Assessment of the Cerebroplacental Ratio in Near‐Term Pregnancies: An Agreement Study With Conventional Ultrasound

Journal of Clinical Ultrasound, EarlyView.
In 80 singleton pregnancies at term, handheld point‐of‐care ultrasound (POCUS) was compared with conventional ultrasound for fetal Doppler assessment. Umbilical artery PI, middle cerebral artery PI, and cerebroplacental ratio showed agreement between devices. Between‐device variability was comparable to intra‐observer repeatability, supporting handheld

Single‐Operator Stress Ultrasound Evaluation of Ulnohumeral Joint Instability Related to Medial Ulnar Collateral Ligament Injury

Journal of Ultrasound in Medicine, EarlyView.
This article introduces a novel, single‐operator stress ultrasound technique for evaluating medial ulnar collateral ligament (MUCL) integrity by assessing medial ulnohumeral joint (MUHJ) widening under valgus stress. Unlike prior methods requiring dual operators, specialized equipment, or the use of hand/wrist weights, this approach was designed for ...

Understanding the Concept of Self‐Performed Ultrasound: A Scoping Review

Journal of Ultrasound in Medicine, EarlyView.
Self‐performed ultrasound is an emerging technology that facilitates adept self‐scans in untrained hands. Inspired by self‐performed imaging in space for more prompt diagnosis and therapy, it has the potential to accurately monitor chronic conditions remotely. However, the lack of supervision and physical restraints can hinder its usability.

Image Quality of Handheld Ultrasound Devices for Lung Ultrasound in Adult Patients with Pneumonia

Journal of Ultrasound in Medicine, EarlyView.
Objectives Handheld ultrasound devices (HHUDs) have increased accessibility and convenience of ultrasonography, but also raised concern regarding image quality and sufficiency for clinical use. This explorative study aims to compare image quality between 3 commercially available HHUDs in patients with pneumonia, and to compare expert agreement on image
