Test-retest and interrater reliability of the functional lower extremity evaluation.

Study Design: Repeated-measures clinical measurement reliability study.

Objectives: To establish the reliability and face validity of the Functional Lower Extremity Evaluation (FLEE).

Background: The FLEE is a 45-minute battery of 8 standardized functional performance tests that measures 3 components of lower extremity function: control, power, and endurance.

Reliability and accuracy of a video analysis protocol to assess core ability.

Objective: To develop and test a method to measure core ability in healthy athletes with 2-dimensional video analysis software (SiliconCOACH). Specific objectives were to: (1) develop a standardized exercise battery with progressions of increasing difficulty to evaluate areas of core ability in elite athletes; (2) develop an objective and quantitative grading rubric with the use of video analysis software; (3) assess the test-retest reliability of the exercise battery; (4) assess the interrater and intrarater reliability of the video analysis system; and (5) assess the accuracy of the assessment.

Design: Test-retest repeatability and accuracy.
