Postural balance, which was measured by stabilometer, was suggested as an important risk factor for falls1. It has been proposed that intermittent control provides a framework to explain human postural control2, usually together with continuous control. We suggest that an event trigger for intermittent control is related to behaviour of the Center of Pressure (COP) movement around Root Mean Squared area (RMS). We investigated whether those COP parameters were influenced by aging. Method Subjects were 41 middle and old age (aged 37-85 years, mean=64.5 years (SD=12.6)). The subjects stood on a stabilometer (the Nintendo Wii Balance Board: WBB). The WBB is a portable, inexpensive, and reliable device that has been reported by many to have good validity for assessing standing balance3. The COP sway was recorded (sampling frequency, 50Hz) for 30s. The participants stood with their feet together, eyes open, and hands at their sides. Informed consent was obtained from all participants. The parameters were derived from the COP values (Figure 1). They were evaluated both for intra-RMS (IRMS) and extra-RMS (ERMS). Originally 12 parameters were translated by Principal component analysis (PCA). In this study, we show a comparison with principal component scores for IRMS and ERMS. Results & Discussion Table 1 shows the highest factor loading on each principal component. The SDVEL (x-axis) is significant factor of the COP (factor loading>0.95). To explain the difference in behaviour between IRMS and ERMS, we evaluated the differential value of principal component score. Figure 2 shows the distance of three dimensional coordinates( x=PC1, y=PC2, z=PC3) between IRMS and ERMS versus the age. These results show an age-related increase in the distance of parameters between intra-RMS and extra- RMS for the COP. These distance measures are significantly related to postural control. The value of distance may be one of the indicators of fall risk. pubtype: Academic Journal doctype: abstract proceedings research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
