OBJECTIVE To evaluate the effectiveness of the Epley maneuver compared with vestibular rehabilitation on patient-reported symptom relief and conversion of the Dix-Hallpike from positive to negative in patients with posterior benign paroxysmal positional vertigo (p-BPPV). DATA SOURCES PubMed, Embase, and the Cochrane Library. REVIEW METHODS A systematic search was conducted. Studies reportin...

background: sellick's maneuver (cricoid pressure) may make laryngoscopic view and tracheal intubation more difficult. this study compared the different techniques of cricoid pressure (cp) regarding to the laryngoscopic view and time to intubation. methods: in142 anesthetized patients, 4 types of cp was randomly applied; a) one-handed cp using thumb, index and middle fingers, b) one-handed cp us...

In this paper a novel approach for detecting unknown target maneuver using range rate information is proposed based on the generalized Page’s test with the estimated target acceleration magnitude. Due to the high nonlinearity between the range rate measurement and the target state, a measurement conversion technique is used to treat range rate as a linear measurement in Cartesian coordinates so...

Moving target cyber-defense systems encompass a wide variety of techniques in multiple areas of cyber-security. The dynamic system reconfiguration aspect of moving target cyber-defense can be used as a basis for providing an adaptive attack surface. The goal of this research is to develop novel control theoretic mechanisms by which a range of cyber maneuver techniques are provided such that whe...

This study was designed to detect the sensitivity of different methods of eliciting knee jerks and to compare the conventional methods with the newly purposed maneuver. Knee jerk (a deep tendon reflex) was elicited in 123 apparently normal population (77 males and 46 females) with three different methods (1) without applying reinforcement, (2) applying Jendrassik maneuver (strong voluntary cont...

Maneuver Regulation, Transverse Feedback Linearization and Zero Dynamics Christopher Nielsen Masters of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2004 The maneuver regulation (or path following) problem has received considerable attention in the control literature where feedback linearization has proven an effective approach to solving the ...

Abnormal responses to a standardized Valsalva maneuver have been proposed as additional Criteria for heart failure. The present study was undertaken to determine the variability of these responses in normal subjects as well as frequency of abnormal responses in cardiac patients. Only phase II responses could be considered reliable for this purpose. Discrepancies between phase II responses were ...

The Valsalva maneuver is frequently used to test autonomic function. Previous work demonstrated that the blood pressure decrease during the Valsalva maneuver relates to thoracic hypovolemia, which may preclude pressure recovery during phase II, even with normal resting peripheral vasoconstriction. We hypothesized that increased regional blood volume, specifically splanchnic hypervolemia, accoun...

The use of nasopharyngoscopy during the application of intrathoracic pressure (Müller maneuver) is frequently employed to establish the site of upper airway obstruction. The Müller maneuver, however, is used when the patient is awake and therefore may not correlate with obstruction occurring during sleep. Aim: to compare the degree of pharyngeal obstruction in the retropalatal and retroglossal ...

Applying manual uterine fundal pressure is a maneuver performed to shorten the second stage of labor. This maneuver involves the application of manual pressure to the uppermost part of the uterus (uterine fundus) and directed towards the uterine axis. How often this maneuver is performed in routine obstetric practice is unclear; however, it is much more frequently performed in developing than d...
