Abstract:
This study was designed to determine the changes in precision of the ultrasound parameters speed of sound (SOS), broadband ultrasound attenuation (BUA), and stiffness index (SI) as a function of bone quality. The instrument used in this investigation was the LUNAR Achilles. Of the 608 female patients who had paired measurements with repositioning, 200 had t scores >/=-1 and 408 had t scores
