Abstract: Introduction In this study we correlated results of ultrasonographic muscle thickness and contractility with facial electromyography (EMG) in patients with unilateral peripheral acute or chronic facial palsy. Methods Two hundred twenty measurements of 4 facial muscles (frontalis, orbicularis oculi, zygomaticus, and orbicularis oris) were performed in 44 patients. Results Facial muscle thickness at rest and during muscle contraction correlated best with EMG insertional activity, and facial muscle contractility correlated with EMG voluntary activity. The correlation was much higher at >14 days after onset of facial palsy. The orbicularis oris, followed by the frontalis muscle, showed the best correlation between ultrasound and EMG. Conclusions Quantitative ultrasound of facial muscles helps confirm the results of facial EMG and is of particular additional value in the first 14 days after onset when the reliability of EMG is low.

TL;DR: The findings indicate that the alteration of EMG signals' complexity was significant (P value = .0001) and more significant alterations in the EMG and EEG signals' complexities in response to the stimuli with higher complexities were observed.

Development of a Coherent Model for Radiometric Core Body Temperature Sensing
01 Sep 2022
TL;DR: In this article , the authors examined the utility of a wideband, physics-based model to determine human core body or brain temperature via microwave radiometry, and the effect of human population variation on emitted brightness temperature is studied by varying the relevant thermal and EM parameters, and brightness temperature emissions are simulated from 0.1 MHz to 10 GHz.

Ultrasound echomyography of facial muscles in diagnosis and follow-up of facial palsy in children
TL;DR: Ultrasonography of facial muscles is also feasible in children and facilitates diagnostics in children with facial palsy and could also be reliably identified in adults.

TL;DR: Muscle ultrasound represents an easily applicable, non-invasive diagnostic tool which adds to neurophysiological testing information regarding morphological changes of muscles early in the course of sepsis and could be useful for screening purposes before subjecting patients to more invasive techniques such as electromyography and/or muscle biopsy.
