- •
Three parameters from normalized power spectrum were chosen and be evaluated the correlation with the lumbar spine BMD.
- •
One of parameters (amplitude for principle frequency, APF) has been proved a significant correlation with BMD.
- •
A multiple regression model including all three QUS variables (BUA, SOS and APF) was somewhat more predictive of BMD than a model including only BUA and SOS.
