METHOD AND DEVICE FOR TESTING AMPLITUDE-AND FREQUENCY CHARACTERISTICS OF STABILOMETRIC PLATFORM

摘要

FIELD: medical engineering; medicine.;SUBSTANCE: device has triangular frame set on stabilometric platform for calibration time. Hinge and pendulum is attached to the frame and triangle vertex. The pendulum is composed of load movably mounted on bar. Angle meter is arranged between lateral sides adjacent to the vertexes. The angle meter and bar have scales. Method involves placing device onto platform producing loading possessing given parameters like generating oscillations of given frequency and amplitude in sagittal plane and then in frontal plane or at an angle of 45° to the planes. The stabilograms are recorded varying load position on the bar and pendulum deviation angle. The obtained parameter values are compared to reference ones and measurement error is estimated. Load position on the bar is measured under the same pendulum deviation angle. The pendulum deviation angle is varied under the same load position.;EFFECT: high accuracy and quality of examination.;4 cl, 1 dwg, 3 tbl
