Objective:

To determine the relationship between asymmetries in lower leg girth and standing heel-rise after anterior cruciate ligament (ACL) reconstruction.

Design:

Single-group posttest.

Participants:

15 at a mean of 30 d after ACL reconstruction.

Measurements:

Lower leg girth and number of repetitions performed on the standing heel-rise test.

Results:

A significant decrease in lower leg girth and number of repetitions performed on the standing heel-rise test for the involved leg. There was also a low correlation between asymmetries in lower leg girth and standing heel-rise test (r = .25).

Conclusion:

Ankle plantar-flexor endurance should be considered when developing rehabilitation programs for the early stages after ACL reconstruction. In this study the ankle of the involved leg attained a significantly smaller angle of maximal standing plantar flexion, suggesting that ankle range of motion should also be assessed. Caution should be used in predicting standing heel-rise asymmetries from asymmetries in lower leg girth in ACL-reconstructed patients.

Context:

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.

Objective:

To determine the test-retest reliability of the standing heel-rise test.

Design:

Single-group repeated measures.

Participants:

Seventeen healthy subjects.

Settings and Infevention:

Each subject was asked to perform as many standing heel raises as possible during 2 testing sessions separated by 7 days.

Main Outcome Measures:

Reliability data for the standing heel-rise test were studied through a repeated-measures analysis of variance, ICC2, 1 and SEMs.

Results:

The ICC2,1 and SEM values for the standing heel-rise test were .96 and 2.07 repetitions, respectively.

Conclusions:

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
