In order to determine the effect of Valsalva maneuver and head rotation on the internal jugular vein (IJV) diameter and cross-sectional area and overlap with the carotid artery (CA) and find the best technique for safe cannulation of the IJV and decrease the risk of CA puncture, the diameter of both the IJV and the CA and percentage of overlap between the two vessels and cross-sectional are...

We performed three maneuvers of the positional test in supine patients: (1) body maneuver, in which patients turned only the body to one side while keeping the head as still as possible; (2) head-only maneuver, in which patients turned only the head to one side while keeping the body still; and (3) head and body maneuver, in which patients turned the head and body together to one side. The nyst...

Introduction The chin-tuck maneuver is the most frequently employed postural maneuver in the treatment of neurogenic oropharyngeal dysphagia caused by encephalic vascular strokes and degenerative diseases. Objective The purpose of this study was to investigate the effectiveness of this maneuver in patients with neurogenic dysphagia and factors that could interfere in it. Methods In this retrosp...

Overtaking in motorsport races is a crucial action order to gain higher position during race. In Formula-E, it not only requires precisely performed overtaking manoeuvres but also appropriate energy management which element race strategy due the limited total amount of on board. This study proposes use optimal control techniques for feasibility and analysis such complex problem. The involves tw...

One-lung ventilation (OLV) has been commonly provided by using a double-lumen tube (DLT). Previous reports have indicated the high incidence of inappropriate DLT positioning in conventional maneuvers.After obtaining approval from the medical ethics committee of First Affiliated Hospital of Anhui Medical University and written consent from patients, 88 adult patients belonging to American societ...

People make anticipatory changes in gait patterns prior to initiating a rapid change of direction. How they prepare will change based on their knowledge of the maneuver. To investigate specific and general strategies used to facilitate locomotor maneuvers, we manipulated subjects' ability to anticipate the direction of an upcoming lateral "lane-change" maneuver. To examine specific anticipatory...

UNLABELLED Benign Paroxysmal Positional Vertigo is the most common peripheral vestibular disorder, especially in the elderly and presents as the predominant etiology in this population of the degeneration of the utricular macula. AIM To compare the effectiveness of the approaches after Epley maneuver. STUDY DESIGN longitudinal cohort. MATERIALS AND METHODS The study included 53 volunteers...
