Evaluation of biomechanical models in posturography

Medical & Biological Engineering & Computing, 1985
Frequency analysis was employed to identify the relationship between movements of the body and the resultant torque on the groundplane. The results of these measurements were compared with computer simulations of the mathematical relationships between torque and movements. Differences between measurements and simulations were examined.

Computerized Dynamic Platform Posturography

Otolaryngology–Head and Neck Surgery, 1997
Computerized dynamic platform posturography is defined in this technology assessment. The review discusses what computerized dynamic platform posturography measures, what the reliability and validity of the information are, and the uniqueness of the information provided. The clinical contribution and indications for testing are discussed.

Stocktaking on the development of posturography for clinical use

Journal of Vestibular Research, 2011
This report identifies fundamental problems to be addressed in order to build relevant clinical tests of human balance while standing. The stated purpose of these tests is identification of lesion site and/or definition of functional balance deficits in a specific patient.

Dynamic Posturography in Cervical Vertigo

Acta Oto-Laryngologica, 1991
Cervical vertigo, the entity of neck disorder and associated vestibular symptoms, was investigated in 15 suspected subjects and results were compared with 15 age-matched controls. A modified dynamic posturography investigation with different head positions was used. Head position was recorded 3-dimensionally with electrogoniometry.

An application of mathematical models in posturography

Journal of Biomedical Engineering, 1982
The 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.

The Use of Posturography in Investigating the Risk of Falling in Frail or Prefrail Older People with Diabetes

The Journal of frailty & aging, 2019
Background In older people, diabetes is associated with an increased risk of falls and frailty. The value of using posturography for evaluating the risk of falling is unclear.

Computerized Posturography, a Development of the Measuring System

Acta Oto-Laryngologica, 1988
A 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, 2001
In 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 ...

Ellipse area calculations and their applicability in posturography

Gait & Posture, 2014
The 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.

Quantitative Posturography: Use in Multiple Sclerosis

IEEE Transactions on Biomedical Engineering, 1981
Average 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.
