Postural Control Mechanisms in the Elderly

The study looked at the contributions of both(prenominal) ankle and hip joints in maintaining balance when standing equable in both groups of subjects using a dual sop up platform so that differences between in exercise(p) and left ankles and right and left hips could be monitored. Subjects stood still as upright as possible on two adjacent platforms and data eruditeness was made in a double leg office with feet at pelvic width. Measurements were taken both with the eyes stretch out and with the eyes closed, and the root mean square (RMS) of the center of stuff (COP) time-varying signals and normalized cross-correlation function were used to examine the interdependence of the different postural witness mechanisms

involved in four successive trials of five minutes each. Ground answer forces and moments were recorded. Samples of analog signals were taken at a 20 Hz frequency with an AD converter and recorder on a computer.

Force platform signals were filtered using a zero put away sixth order Butterworth low pass filter at 10 Hz. The accuracy for the study COP was 0.2 mm.

The effect of vision was significant in all tests in full-blooded subjects, but only RMS values of CO[P.sub.c] and CO[P.sub.net] in the anteroposterior direction were affect by vision deprivation in DSN patients. This shows that mediolateral p
