An application of mathematical models in posturography
Journal of Biomedical Engineering, 1982The measurement of the horizontal displacements (HD) of the centre of mass of the human body when standing still, is often performed by means of a platform. The resulting measured HD as a function of time, both in the left-right or sinister-dexter and the posterior-anterior direction, are known as stabilograms.

Computerized Posturography, a Development of the Measuring System
Acta Oto-Laryngologica, 1988A computerized posturography system is composed of a custom made strain gauge force platform and it utilizes commercially available amplifiers. The body sway response signals are digitized for the calculation of the following parameters by a computer: average velocity of body sway, mean value for fore-aft and lateral body sway, and maximal amplitude of

Multi-stimulus multi-response posturography
Mathematical Biosciences, 2001In this study a method for the analysis of simultaneous multiple measurements of kinematics and stabilizing forces related to human postural dynamics is proposed. Each subject in a group of normal subjects (n=10) was tested with eyes-open and eyes-closed with simultaneous but uncorrelated vestibular and proprioceptive stimuli in order to investigate ...

Quantitative Posturography: Use in Multiple Sclerosis
IEEE Transactions on Biomedical Engineering, 1981Average displacement of anterior-posterior sway over a 10 s epoch in the quietly standing human was determined for both the eyes open and eyes closed conditions. Average difference of displacement between these two conditions was calculated. From the control measures (n = 139) normative values were defined for three age ranges.

Ellipse area calculations and their applicability in posturography
Gait & Posture, 2014The quantification of postural sway is considered to be an essential part of posturography and is important for research and clinical utility. A widely used method to calculate the scatter of center of pressure data is an ellipse that encloses about 100(1-α)% of the observations.

Intraobserver reliability of posturography in healthy subjects
Somatosensory & Motor Research, 2013Reliability of posturography is essential for the identification of intervention effects in any setting (e.g., sport, rehabilitation). The purpose was to establish the intraobserver reliability of a posturographic method in asymptomatic subjects (n = 30).

Effect of Alcohol Measured by Dynamic Posturography
Acta Oto-Laryngologica, 1991Thirteen healthy male volunteers aged 21-42 years (mean 27 years) were assessed by dynamic posturography before and after ingestion of alcohol. Each subject was given 0.6 g alcohol per kg body weight in fruit juice to be drunk within 10 min. Alcohol levels in blood samples at 15, 45 and 75 min after ingestion were assessed by gas chromatography ...

Posturography and Balance Problems in Older People
Journal of the American Geriatrics Society, 1995OBJECTIVE: To determine which measurements and test conditions on posturography are most useful for identifying balance problems in older people.SUBJECTS: Two samples of 70 community‐dwelling older subjects (>75 years). One group (controls) considered their balance normal for their age, and the other (patients) complained of imbalance.MEASUREMENTS ...

Archives of Otolaryngology - Head and Neck Surgery, 1996
I greatly appreciate the opportunity to address the comments by Dobie and by Black and Homer. A brief supplemental analysis of the original data 1 is included herein to address the questions raised by my colleagues and to further support the validity of my original findings. A meta-analysis is a quantitative review of existing literature.

Posturography does not Test Vestibulospinal Function
Otolaryngology–Head and Neck Surgery, 1999The clinical usefulness of posturography is unknown, despite its costing more than $500 per test in some areas of the United States, including Boston. We cross‐sectionally and prospectively studied blinded vestibulo‐ocular and vestibulospinal tests from 29 stable patients with chronic vestibular hypofunction; 22 patients were affected bilaterally (BVH),
