[Purpose] The purpose of this study was to examine whether Nordic walking exercise can relieve low back pain and change the spine shape in elderly women. [Subjects] Sixteen elderly women with chronic low back pain from N University in Chungcheong-do, South Korea, were enrolled. [Methods] The participants were asked to walk in an upright posture, with the head upright and looking forward. The No...

In this paper the geometrical relationship of the folds which exist in the Folded Zagros Mountains, including Asef Mountain (northern Iran), were studied. The southern and western zones of the Zagros Mountains are called the Folded Zagros. These zones extend approximately 1,375 km in length with a width ranging from 120 to 250 km. Asef Mountain is located in northern Shiraz (from northern Sarda...

Maintenance of human upright stance requires the acquisition and integration of sensory inputs. Conventional measures of sway have had success in identifying age- and some disease-related changes, but remain unable to address the complexities and dynamics associated with postural control. We investigated the effects of vision, surface compliance, age, and gender on the spectral content of cente...

This paper describes the method for trajectory tracking and balancing the Self Erecting Single Inverted Pendulum (SESIP) using Linear Quadratic Regulator (LQR). A robust LQR controller for stabilizing the SESIP is proposed in this paper. The first part of the controller is a Position Velocity (PV) controller to swing up the pendulum from its hanging position by moving the pendulum left and righ...

Left ventricular (LV) performance at rest and during multilevel exercise in the supine and upright positions was studied in seven normal subjects with equilibrium radionuclide ventriculography. The mean left ventricular end-diastolic volume (LVEDV) during supine rest was 107 4 10 ml (± SEM) and 85 ± 6 ml (p < 0.02) in the upright position; the mean resting left ventricular end-systolic volumes ...

We sought to clarify the nature of the face processing strength commonly observed in individuals with Williams syndrome (WS) by comparing the face recognition ability of persons with WS to that of persons with autism and to healthy controls under three conditions: Upright faces with neutral expressions, upright faces with varying affective expressions, and inverted faces with neutral expression...

Research has been done on the maximum reach and ingress/egress of upright seats. However, research on recumbent seats and comparisons between recumbent and upright seats is limited. By using an eight-camera Vicon motion capture system and C-motion Visual 3D modeling software, this research compared the ingress/egress joint kinematics and maximal planar reach of an upright seat with a recumbent ...

Face inversion effects are used as evidence that faces are processed differently from objects. Nevertheless, there is debate about whether processing differences between upright and inverted faces are qualitative or quantitative. We present two experiments comparing holistic processing of upright and inverted faces within the composite task, which requires participants to match one half of a te...

Measured by a variety of techniques, the overall ventilation-perfusion relationship of the normal human lung is different in supine and upright positions, and in the upright position, the upper regions of the lung are relatively poorly perfused (1-4). Similarly, pulmonary diffusing capacity (DL) is reduced when normal subjects change from supine to upright positions (5, 6); in the upright posit...
