OBJECTIVES To compare the surgical outcomes of inferior oblique (IO) myectomy in congenital superior oblique palsy (SOP) according to the presence of the trochlear nerve identified with high-resolution MRI. DATA EXTRACTION Forty-one congenital SOP patients without a trochlear nerve (absent group) and 23 patients with a trochlear nerve (present group) who underwent IO myectomy as the primary s...

Background: Long-term computer use as an ergonomics risk factor can generate musculoskeletal disorders, especially in the neck. This study aimed to investigate the effect of a self-management exercises intervention on both neck pain, and head and neck angles among university employees in 2021. Materials & Methods: This experimental study was performed on 85 university staff (experimental group...

Head-up tilt test is useful for exploring neurally mediated syncope. Adenosine is an ATP derivative implicated in cardiovascular disturbances that occur during head-up tilt test. The aim of the present study was to investigate the impact of hyperoxia on adenosine plasma level and on hemodynamic changes induced by head-up tilt testing.Seventeen healthy male volunteers (mean age 35 ± 11 years) we...

OBJECTIVE To investigate the haemodynamic effects of varying the angle of head up tilt. METHODS 20 healthy subjects (12 female, eight male; mean (SD) age 33.6 (8.4) years) underwent head up tilt for five minutes to each of four angles of tilt in random order, with a five minute rest period at the horizontal between each angle. Forearm blood flow was measured using intermittent occlusion mercu...

In birds, a lateralised visual input during early development importantly modulates morphological and functional asymmetries of vision. We tested the hypothesis that human handedness similarly results from a combination of inborn and experience-driven factors by analysing sidedness in children suffering from congenital muscular torticollis. These children display a permanently tilted asymmetric...

Objectives The first objective was to evaluate feasibility of head tilt testing and the motorized head impulse test (mHIT) for the quantification of vestibular function and its possible change in different otoneurological patient groups. The second objective was to compare these objective findings with symptoms and other signs for these patients. Methods Head tilt was measured by using a commer...

It has been proposed that asymmetry in the inner ear underlies various manifestations of brain-behaviour asymmetry in the human. Specifically, Previc (1991) argued that an otolith imbalance manifests itself in an asymmetrical head posture, and later (1994) suggested that head tilt may be consonant with other measures of human laterality. The present study tested the reliability of head tilt acr...

To test the hypothesis that systemic inhibition of nitric oxide (NO) synthase does not alter the regulation of sympathetic outflow during head-up tilt in humans, in eight healthy subjects NO synthase was blocked by intravenous infusion of NG-monomethyl-L-arginine (L-NMMA). Blood pressure, heart rate, cardiac output, total peripheral resistance (TPR), and muscle sympathetic nerve activity (MSNA)...
