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