OBJECTIVE: To examine the test-retest reliability of grip strength when using the
mean value, the best value, and the first value of 2 grip strength measurements
and to determine the cutoff value for separating those who were able or unable to
perform a heavy task with their hands in a group of Taiwanese adults. DESIGN:
Cross-sectional test-retest study. SETTING: Local community centers.
PARTICIPANTS: Community-dwelling older adults (N=469; age, >/=60y).
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Self-reported measure of
ability to perform heavy tasks with their hands and grip strength. RESULTS: The
test-retest reliability of grip strength in older adults was good (intraclass
correlation coefficient >/=.85) when using the mean value, the best value, or the
first of 2 measurements. Optimum cutoff values were 28.5 and 18.5kg, and values
with 75% sensitivity were 34 and 22kg for men and women, respectively.
CONCLUSIONS: The test-retest reliability of grip-strength measurement in a group
of Taiwanese older adults was acceptable when the best value, the mean value, or
the first of 2 measurements was used. The reported mean and cutoff values for
grip strength also could serve as reference values for the public to monitor
their grip strength performance and identify those at risk for early
intervention.
