Reliability and validity of trunk accelerometry-derived performance measurements in a standardized heel-rise test in elderly subjects.

Abstract

This cross-sectional study evaluated the intrasession reliability and concurrent validity of trunk accelerometry (with force plate measurements) for vertical ground reaction force and external mechanical power recorded during a standardized heel-rise (HR) test in 54 elderly subjects (mean +/- standard deviation age 81.2 +/- 6.4 yr).Peak force as well as… (More)
