The standing heel-rise test has been recommended as a means of assessing calf-muscle performance. To the authors' knowledge, the reliability of the test using intraclass correlation coefficients (ICCs) has not been reported.
To determine the test-retest reliability of the standing heel-rise test.
Single-group repeated measures.
Seventeen healthy subjects.
Each subject was asked to perform as many standing heel raises as possible during 2 testing sessions separated by 7 days.
Reliability data for the standing heel-rise test were studied through a repeated-measures analysis of variance, ICC2, 1 and SEMs.
The ICC2,1 and SEM values for the standing heel-rise test were .96 and 2.07 repetitions, respectively.
The standing heel-rise test offers clinicians a reliable assessment of calfmuscle performance. Further study is necessary to determine the ability of the standing heel-rise test to detect functional deficiencies in patients recovering from lower leg injury or surgery
