Article Abstract
Objective: This study aimed to evaluate sternocleidomastoid (SCM) muscle properties in infants with Congenital Muscular Torticollis (CMT) using myotonometry and determine its sensitivity to changes following physiotherapy.
Methods: Twenty-five infants (0-12 months) diagnosed with CMT participated in this study from May 2023 to February 2024. They underwent an 8-week physiotherapy program. Muscle tone, elasticity, and stiffness were measured using myotonometry, muscle strength by the Muscle Function Scale (MFS), and neck range of motion by an arthrodial protractor before and after treatment.
Results: The mean age was 4 ± 1.56 months. Significant differences in SCM tone and stiffness between affected and intact sides were observed pre-treatment (p<0.05) but were not significant post-treatment (p>0.05). Intra-group improvements were significant for muscle tone (p=0.005), elasticity (p=0.009), stiffness (p=0.009), strength (p=0.006), and neck range of motion (p=0.021). Muscle tone decreased by 19.65%, muscle stiffness by 24.99%, and muscle elasticity improved by 9.42%. Passive lateral flexion increased by 59.09% and passive rotation by 25.40%.
Conclusions: SCM muscle properties differ between sides in individuals with CMT; however, myotonometry effectively detects improvements following physiotherapy, making it a valuable clinical evaluation tool. Nevertheless, the relatively small sample size should be taken into account when interpreting the findings.

Sleep paralysis, colloquially known as "ghost pressing" is a state of momentary bodily immobilization occurring either at the onset of sleep or upon awakening. It is characterized by atonia during rapid eye movement (REM) sleep that continues into wakefulness, causing patients to become temporarily unable to talk or move but possessing full consciousness and awareness of their surroundings. Sleep paralysis is listed in the International Classification of Sleep Disorders, 3rd Edition (ICSD-3) as a parasomnia occurring during REM sleep that be classified as either isolated or narcolepsy-associated.

Background: Pulmonary neuroendocrine cells (PNECs) are specialized airway epithelial cells with dual sensory and secretory functions. They release bioactive mediators --including neuropeptides such as calcitonin gene-related peptide (CGRP) and gastrin-releasing peptide (GRP), and neurotransmitters such as 5-hydroxytryptamine (5-HT) and γ-aminobutyric acid (GABA) --that regulate airway smooth-muscle tone, mucus production, and immune responses. In chronic obstructive pulmonary disease (COPD), these PNEC-derived mediators contribute to airway inflammation, remodeling, and smooth-muscle dysfunction.

Idiopathic scrotal calcinosis (ISC) is a rare, benign dermatological condition consisting of deposits of calcium within the scrotal skin. On examination, ISC is characterized by painless, firm nodules and papules localized to the scrotal skin. Typically presenting in adolescence or early adulthood, ISC is more prevalent in males aged 20 to 40, though cases have been reported across all age groups.

The regulation of vascular tone underlies normal cardiovascular homeostasis, ensuring appropriate distribution of blood flow to tissues and maintenance of blood pressure. Computational modeling and simulation constitute a powerful framework for deciphering plausible mechanisms of autonomic signaling in vascular smooth muscle across spatial and temporal scales and allow for prediction of emergent nonlinear effects of perturbations. Integrative computational modeling approaches are now beginning to inform the precision use of calcium channel blockers, Angiotensin II type 1 receptor antagonists, and lipid-modulating therapies in cardiovascular disease.

The control of muscle relaxation is not simply the cessation of a muscle contraction, but a dynamic control mechanism for the next movement. Muscle relaxation is triggered by neurophysiological control of the central nervous system. Here, two relaxation strategies were compared, Ballistic and Ramp conditions, and the dynamics of excitability changes between the two relaxation strategies were analyzed.
