Abstract

This research study employed a non-experimental quantitative type of research. It was conducted at Wang building, De La Salle Health Sciences Institute and was participated by 11 recreational basketball players fromDLSHSI PT Batch 2019 without any history or current complaint of knee injury. The evaluators for the real-time observational screening consisted of three (3) licensed physical therapists who have at least five (5) months of experience in sports rehabilitation. Moreover, 2D video motion analysis was evaluated by one (1) licensed physical therapist who has a depth in converting the video into frames, plotting the landmarks for 2D analysis and interpreting the results of the video analysis. The implementation of the study was done in two testing occasions to test for interrater and to test retest reliability. Cohen’s Kappa Coefficient for concurrent validity of real-time observational screening with the value of -0.094, Krippendorff’s alpha coefficient for interrater reliability with a value of -0.0572, Cohen’s Kappa Coefficient for test-retest reliability of real-time observational screening with a value of .369 and Intraclass Correlation Coefficient for intrarater reliability of 2D Motion Analysis yielded to a value of 0.929. Given the results of the study, Real-time Observational Screening is therefore not reliable and cannot be a valid tool in identifying presence of dynamic knee valgus during drop jump landing. Therefore, Real-time Observational Screening should not be used when identifying presence of dynamic knee valgus. The researchers concluded that dynamic knee valgus measurements with the use of Real-time Observational Screening were not reliable both in repeated measurements and between different raters. Furthermore, dynamic knee valgus measurements generated from the Real-time Observational Screening were proven to be invalid when compared with measurements from 2D Video Motion Analysis using Skillspector.
