BACKGROUND In a cross-sectional study we examined whether the haemodynamic response to upright posture could be divided into different functional phenotypes, and whether the observed phenotypes were associated with known determinants of cardiovascular risk. METHODS Volunteers (n = 470) without medication with cardiovascular effects were examined using radial pulse wave analysis, whole-body im...
1. This study was done to examine the possibility that escape from the sodium retention produced by aldosterone may be associated with an inhibition of prolactin secretion. Plasma prolactin concentrations were determined in seven patients with adrenal adenoma and aldosteronism, before and after unilateral adrenalectomy, at a time when they were in balance on a sodium intake of 109 mmol/day. 2. ...
Upright stance on a balance board is a skill requiring complex rearrangement of the postural control. Despite the large use of these boards in training the standing posture, a comprehensive analysis of the learning process underlying the control of these devices is lacking. In this paper learning to maintain a stable stance on a multiaxial oscillating board was studied by analyzing performance ...
The present research aimed to analyze values of the autocorrelation function measured for different time values of ground reaction forces during stable upright standing. It was hypothesized that if recording of force in time depended on the quality and way of regulating force by the central nervous system (as a regulator), then the application of autocorrelation for time series in the analysis ...
Background: Falls is due to people's failure of balance recovery. The purpose of this study was to investigate the effect of trunk extensor muscle fatigue on static balance control in young healthy adults compared to middle aged participants. Methods: Ten young adult females (23 ± 1.6 years) and 6 middle-aged females (51 ± 5.4 years) participated in stand immobile test on a force plat...
INTRODUCTION Many existing balance control models have adopted a single-segment inverted pendulum to model the human body, and have focused on investigating postural sway only in the sagittal plane (e.g. Maurer et al., 2005). However, evidence indicates that postural sway in the frontal plane is important, and able to account for different balance control mechanisms as well (e.g. McClenaghan et...
We investigated the relationships between the ability to maintain balance in an upright stance and center-of-pressure (COP) dynamic properties in young adults. Included in this study were 10 healthy male subjects in each of two groups with respect to balance ability. Balance ability was evaluated according to the length of time a subject stood on one leg with his eyes closed. The means and rang...
