Embodiment Construction

[0030]FIG. 1A is a cross-sectional view perpendicular to the plane of the force sensor of the force estimation device of the present invention. FIG. 1B shows a top view of the force estimation device or a top view of the plane of the force sensor. In FIG. 1 , only those components of the force estimating device required for force detection (ie the components of the measuring unit of the force estimating device) are shown. The block diagram in Fig. 2 shows an evaluation unit (see below) for estimating the detected force. The measuring unit and the evaluating unit communicate with each other to exchange data. The force evaluation device has a rigid, planar, triangular base plate 3 . In this embodiment, the bottom plate is made of steel. The triangular structure is formed by an equilateral triangle with a side length of 60 cm. The three vertices of the triangle of the base plate are rounded. The base plate 3 has a thickness (perpendicular to the plane of the force sensor, ie...

Abstract

The invention relates to a force evaluating device by means of which forces can be determined and evaluated in a time-resolved manner. Said force evaluating device comprises at least three force transducers that are disposed on one plane and are coupled to a support plate on which a person can walk. The pressure that is applied to the force transducers via the support plate can be detected in a time-resolved fashion with the aid of the force transducers. The power spectrum of said forces is calculated from the detected measured values by means of an evaluation unit. Moreover, the determined force-time correlation can be differentiated according to the time, wherefrom additional characteristics of the effective forces can be determined. The invention can be used mainly in the area of preventive health care, rehabilitative measures, and objectification of the influence of alcohol and drugs on human reactivity.

Description

technical field [0001] The present invention relates to devices and methods for determining balance characteristics. The device of the invention is particularly useful for the quantitative detection of functions and disturbances of the human motor and sensory balance systems. Background technique [0002] Balance in a standing person is ensured by the coordinated interaction of the motor and sensory systems of the human musculoskeletal system and specific functions of the central nervous system, spinal motor system, and supraspinal motor system . Currently, standing balance is studied through different tests that only allow subjective evaluation by observers, for example by using a stopwatch. [0003] On the one hand, the spinal motor system and supraspinal motor system can develop problems due to disease or trauma, and on the other hand, they can age. As a result, all tissues involved in ensuring a safe standing position or correct voluntary and involuntary movements may...
