BACKGROUND Evaluate the feasibility of active delivery of the anterior arm during spontaneous delivery. This maneuver could decrease incidence of second-degree perineal tears because it reduces fetal biacromial diameter. METHODS An observational comparative prospective study was conducted at our teaching maternity from July 2012 to March 2013. The study included 199 nulliparous women ≥18 year...

Tongue-hold swallow (THS) is a therapeutic maneuver used to increase the posterior pharyngeal wall motion during swallowing. This maneuver has also been reported to result in increased activation of the suprahyoid muscles. The hypothesis of this study was that the degree of suprahyoid muscle activation would depend on the tongue protrusion-length. The aim of this study was to investigate the ac...

Treatment of pulmonary contusion when adequately established is very simple in most cases. Pathophysiological changes occur as a result of the effects produced by loss of chest wall integrity, accumulation of fluid in the pleural cavity, obstruction of the airways and lung dysfunction. The alveolar recruitment maneuver is the reopening of collapsed lung areas by increasing inspiratory pressure ...

[Purpose] The purpose of this study was to compare the effect of childbirth delivery method on vaginal pressure and abdominal thickness during the Valsalva maneuver (VAL). [Subjects] Thirty healthy female volunteers (26-39 years of age) were selected for this research. Their delivery histories were: nulliparous 10, vaginal delivery 10, and Cesarean delivery 10. None of the participants had a hi...

Evidence Six systematic reviews of RCTs consistently supported Epley maneuvers (as classically described) despite considerable heterogeneity among trials.1-6 • Most recent review (11 RCTs, N = 745)1: -Results were statistically significant for the Epley maneuver versus control at 24 hours and 4 weeks. —Resolution of symptoms (5 RCTs, n = 273): 56% versus 21% with control (NNT = 3). —Positive to...

require the use of color in order to fully convey their points. Foreword Six years ago, the Marine Corps embarked on new efforts based on the " New Sciences " to provide quantitative answers, where possible, to the important questions facing military decision-makers. Maneuver Warfare Science 1998 described some initial thoughts on providing support to these decision-makers in areas that our tra...

The purpose of this study was to investigate the influence of the Valsalva maneuver (VM) on cardiac hemodynamics in patients with patent foramen ovale (PFO). Sixty-five patients who were highly suspected to have PFO were included. The changes in E, A, E/A ratio of mitral valve blood flow, E, A, E/A ratio of tricuspid valve blood flow, left ventricular end-diastolic volume, area and right atrial...

Abstract The powered-descent landing (PDL) phase of the Tianwen-1 mission began with composite backshell—parachute (CBP) separation and ended landing-rover touchdown. main tasks this were to reduce velocity lander, perform avoidance maneuver, guarantee a soft PDL overcame many challenges: performing divert maneuver avoid collision CBP while simultaneously avoiding large-scale hazards; slowing d...

UNLABELLED The effects of Epley's maneuver in benign paroxysmal positional vertigo (BPPV) associated with Menière's disease are controversial. AIMS To evaluate the progression of positional vertigo and nystagmus after one or more of Epley's maneuvers in BPPV associated with Menière's disease, and the recurrence of BPPV. METHOD a retrospective study of 62 patients with BPPV associated with M...

UNLABELLED The effectiveness of postmaneuver postural restrictions is controversial in patients with benign paroxysmal positional vertigo. AIM To verify the role of postural restrictions in patients with benign paroxysmal positional vertigo of posterior canal, submitted to a single Epley maneuver. STUDY DESIGN clinical prospective. MATERIAL AND METHOD Fifty eight patients with benign paro...
