The primary aim of this study is to compare traditional muscle function tests with
computerized versions using body-worn motion sensors and video motion analysis of the same
tests. The investigators selected the Timed Up and Go (TUG) test as the investigators
primary variable for this aim with several other function tests (e.g., repeated chair rise,
6-meter walk, 2-minute walk, Romberg stance, semi-tandem / tandem stance) as secondary
variables. The investigators primary hypothesis is that the computerized versions of the TUG
test are highly correlated (>0.9) with the traditional method, but with comparable or better
reproducibility. Secondary analyses will correlate other function tests with their
computerized version, again with the hypothesis that they are highly correlated and that
computerized versions are of similar or better reproducibility. This analysis will also
compare traditional assessments of balance with a computerized balance method, computerized
dynamic posturography.
