Abstract

Abstract: Objectives: To determine the validity and inter-session reliability of the Vail Sport Test™. Design: Cohort study-exploratory methodological research design. Setting: Clinical Research Laboratory. Participants: Forty-eight participants who underwent ACL-R. Main outcome measure: Participants performance on the Vail Sport Test™ was graded by an experienced rater in real-time, and simultaneously recorded by a three-dimensional (3D) motion capture system. Construct validity was assessed using the reference standards of the camera system and the IKDC short form. To determine the between-day reliability, a subset of participants returned to repeat the test. Results: There were no significant difference between the scores collected in real-time and from the kinematic data on the involved limb ( p = 0.222). There was a significant difference for the uninvolved limb ( p = 0.015). There was no significant difference between the scores collected in real time and those of the IKDC ( p = 0.885). Good inter-session reliability (ICC = 0.787) was found for the involved limb. Conclusion: The results of this study showed good reliability and partially support the validity of the Vail Sport Test as a measure of readiness to return to play. Highlights: The Vail Sports Test is utilized as part of return to play testing to assist in clinical decision making. It was found to be valid as compared to motion capture grading for the injured limb. It was found to have good inter-session reliability and previously shown to have good intra-rater reliability.
