ABSTRACT

Two-dimensional (2D) video is often used to evaluate running gait. Cost effective and clinically applicable methods have not been validated. The objective of this study was to evaluate the concurrent validity and agreement of methods used to determine step rate (SR) and foot strike pattern (FSP) during running using 2D video. We observed excellent agreement assessing SR from a 30 Hertz (Hz) video for 10 seconds (s) and multiplying it by 6. We observed excellent interrater agreement assessing FSP for 10s at 240 Hz. These 10s methods for assessing running may be used to inform clinical decision making when evaluating running gait. Key point's Two-dimensional video assessment at 30 Hz demonstrated high intra- and interrater reliability for detecting step rate; the 10-second method is valid and reliable for detecting step rate when compared to the 60-second method; Detecting foot strike using a 2-point scale is more reliable at 240Hz rather than 30Hz.
