Many clinicians use functional-performance tests to determine an athlete’s readiness to resume activity; however, research demonstrating reliability of these tests is limited.
To introduce the Lower Extremity Functional Test (LEFT) and establish it as a reliable assessment tool.
Week 1: Subjects participated in a training session. Week 2: Initial maximal-effort time measurements were recorded. Week 3: Retest time measurements were recorded.
The University of Wisconsin–La Crosse (UW-L) and the University of Central Florida (UCF).
27 subjects from UW-L and 30 from UCF.
Main Outcome Measures:
Time measurements were analyzed using intraclass correlation coefficients (ICCs).
ICC values of .95 and .97 were established at UW-L and UCF, respectively.
The LEFT is a reliable assessment tool.
