Computerized system for posturographic research based on the ADAPT language for analysis of analogue signals.
A description is given of a system for posture analysis based on a specialized language ADAPT for analysis of analogue data, guaranteeing: 1. Analogue-to-digital conversion of the input signals with dialogue determination of the conversion parameters and monitoring of the signals on the screen. 2. Storage of the data on a diskette in a format guaranteeing high density of the data and fast exchange with the computer. 3. Calculation of the following parameters of the stabilogram and statokinesigram separately for open and for closed eyes: a) Anterior-posterior and lateral components of the path of the projection of the force centre SPAP and SPLAT; b) Mean frequency of the sways: fAP and fLAT; c) Ratio between the anterior-posterior and the lateral sways: AP/LAT. d) Surface A covered by the shifting of the centre of force; e) The path (SP) of the centre of application of the force; f) Mean amplitude (MA) of the sways for one second; g) Mean frequency (MF) of the sways. Romberg's coefficients are calculated for all parameters. 4. High speed of the calculations. 5. Graphic and digital display of all results on the screen from where they can be transferred to a printer, if necessary.
