Objectives
Establish the concurrent validity between 2D video analysis and 3D motion analysis of frontal plane lower limb movements during multidirectional landing tasks. Design Correlation study. Setting University Biomechanics laboratory. Participants 34 (19 male, 15 female) uninjured physical active individuals. Main outcome measures knee abduction and hip adduction angles during a variety of single leg landing tasks. Results 2D knee abduction showed an association with 3D knee abduction angle ranging from r = 0.17–0.42 across the tasks, with r2 values ranging between 0.03 and 0.17. 2D hip adduction angle in both legs reported a strong and significant correlation with 3D hip adduction angle, ranging from r = 0.70–0.90 across all tasks. Linear regression analysis (r2) revealed that 49–81% of 3D hip adduction angle can be explained by 2D measurement. Conclusion It might be difficult to explain 3D knee abduction angle using 2D video analysis during single leg landing tasks, whereas 2D hip adduction angle is a strong predictor or 3D hip adduction angle. It would appear 2D video analysis has strong concurrent validity when assessing hip adduction angle, but it is weak when assessing knee abduction angle during a variety of single leg landing tasks. |
