OBJECTIVES To evaluate the efficacy and clinical usefulness of laryngeal electromyography (EMG) in the evaluation and management of vocal cord mobility problems in children; and to determine the ability of laryngeal EMG to differentiate vocal fold fixation versus paralysis. STUDY DESIGN Case-series review of 8 children with vocal cord immobility who underwent laryngeal EMG. METHODS Eight ch...

Different combinations of volume and pressure overloads cause different left ventricular (LV) geometric adaptations. Whereas this cause-effect relationship is obvious for valve disease, because clear-cut types of overloads are easily recognizable, in systemic hypertension the type of cardiac load is less evident but at least as important for LV adaptation. Human arterial hypertension encompasse...

Background: The amount of anterior tibial translation during rehabilitation exercises is a key factor in organizing exercise regimen after anterior cruciate ligament injury. Excessive anterior tibial translation could increase the magnitude of tension imposed on injured and reconstructed anterior cruciate ligament knees. Forward lunge and open-kinetic knee extension exercises are commonly used ...

OBJECTIVE The goal of this study was to determine whether wall stress at rest and during stress could explain the influence of left ventricular (LV) morphology on the accuracy of dobutamine stress echocardiography (DSE). BACKGROUND The sensitivity of DSE appears to be reduced in patients with concentric remodeling, but the cause of this finding is unclear. METHODS We studied 161 patients wi...

This study compares the changes in pathway and center of gravity (COG) on the calcaneus of non-involved and involved sides according to eccentric and concentric strengthening in patients with unilateral Achilles tendinopathy. The goal was to define the biomechanical changes according to eccentric strengthening for the development of clinical guidelines. Eighteen patients with Achilles tendinopa...

The study investigates the effects of the 11+ and HarmoKnee injury prevention programmes on knee strength in male soccer players. Under-21-year-old players (n=36) were divided equally into: the 11+, HarmoKnee and control groups. The programmes were performed for 24 sessions (20-25 min each). The hamstrings and quadriceps strength were measured bilaterally at 60°·s(-1), 180°·s(-1) and 300°·s(-1)...

OBJECTIVES We examined the prognostic significance of concentric remodeling of the left ventricle in patients with essential hypertension and normal left ventricular mass on echocardiography. BACKGROUND An echocardiographic pattern of concentric remodeling of the left ventricle has been associated with clinical features of increased cardiovascular risk, but the independent prognostic value of...

Concentric tube manipulators have the diameter of needles and are consequently amenable to delivery into the human body through small ports in an endoscope. When this is done, the surgeon must manipulate both the endoscope and one or more concentric tube robots simultaneously. In this paper we explore a hand-held approach to this user interface challenge, in which the surgeon has direct physica...

The ventral form vision pathway of the primate brain comprises a sequence of areas that include V1, V2, V4 and the inferior temporal cortex (IT) [1]. Although contour extraction in the V1 area and responses to complex images, such as faces, in the IT have been studied extensively, much less is known about shape extraction at intermediate cortical levels such as V4. Here, we used functional magn...
