Abstract: Although adequate hip extension strength is necessary for the successful
performance of weight-bearing activities, practical quantitative procedures
for measuring hip extension strength are lacking. We sought, therefore, to
describe a practical procedure and the reliability and validity of
measurements obtained with it. Apparently healthy individuals (10 men, 10
women) of 18-27 years participated. One male and one female examiner tested
all subjects in supine with a hand-held dynamometer during 2 sessions, 1
week apart. Inter-tester and test-retest reliability of measurements were
good to excellent (intraclass correlation coefficients = 0.827-0.949). Known
groups validity was supported by a demonstration of significant differences
in the strength of men and women participants. Based on the findings of this
study we can recommend the procedure for testing with other populations.
