INTRODUCTION Progressive supranuclear palsy (PSP) is characterized by early postural instability and backward falls. The mechanisms underlying backward postural instability in PSP are not understood. The aim of this study was to test the hypothesis that postural instability in PSP is a result of dysfunction in the perception of postural verticality. METHODS We gathered posturography data on 1...

Background: Dizziness is a non-specific term used by patients to describe a variety of symptoms. The terms dizziness, vertigo, faintness, and blackouts are not synonymous but are often used interchangeably by patients. Postural blackout is a subtype of dizziness and is a result of postural hypotension, a feature of autonomic dysfunction. Case reports: We present detailed case histories of two p...

Previous studies have shown significant effects of increased postural anxiety in healthy young individuals when standing quietly or performing voluntary postural tasks. However, little is known about the influence of anxiety on reactive postural control. The present study examined how increased postural anxiety influenced postural reactions to unexpected surface rotations in multiple directions...

This study tests the hypothesis that increased arterial stiffness is associated with postural hypotension in older adults. Aortic pulse wave velocity and postural blood pressure (BP) response were assessed in 49 nondiabetic community-dwelling normotensive (n=27) and hypertensive (n=22) older adults (mean age+/-SD, 71+/-6.7 years) who were not receiving vasoactive medications. During the 5-minut...

Postural stability is an important measure in both research and clinical practice. A portable, easy to use device that can provide higher resolution than current clinical tests may allow for better identification of patients or athletes with postural stability deficits. The purpose of this study was to evaluate the ability of a tri-axial accelerometer to quantify postural stability in a healthy...

OBJECTIVES This study examined the postural performance of two groups of male skiers competing at different levels and the consequences on postural control of the suppression of visual afferences by eye closure. METHODS Seven national level (NAT) skiers and 7 regional level (REG) skiers were asked to stand as still as possible on a force platform with eyes opened and closed and while wearing ...

OBJECTIVE This review details the anatomy and interactions of the postural and somatosensory reflexes. We attempt to identify the important role the nervous system plays in maintaining reflex control of the spine and posture. We also review, illustrate, and discuss how the human vertebral column develops, functions, and adapts to Earth's gravity in an upright position. We identify functional ch...

Background: Elderly is someone who classified as old and experiencing the aging process. The risk of falling decreased function are two many geriatric syndromes, which affected by various things, such muscle weakness, imbalance, poor posture.
 Objective: This study aimed to determine difference in effect adding deep breathing exercises on postural training only reducing hyperkyphosis curve...

BACKGROUND The purpose of this study was to determine the extent to which measures of lower extremity strength and power contribute to the ability of older men and women to restore postural equilibrium using a single-step recovery following a large postural disturbance. METHODS The postural disturbance, which has been used as a surrogate for forward-directed falls, involved a sudden release f...

Increased postural sway in the elderly has been viewed as a degradation of the postural control system that may be related to an increased risk of falls in the elderly [1]. This study demonstrated the degradation of postural control with aging by quantifying the changes seen in the temporal structure as well as the magnitude of movement of the center of pressure during quiet stance. The analysi...
