Gait analysis on a treadmill can be used to identify spatial-temporal parameters of gait in both healthy  and injured  individuals. Instrumented treadmills have been considered the gold standard for assessing certain running parameters; however, these treadmills are costly, require trained personnel to operate, and use custom code to calculate variables of interest from the raw data. The OPTOGait system is portable and can be used on any flat surface or treadmill to collect data. OPTOGait uses high-density photoelectric cells between transmitting and receiving bars which detect interruption in light signals due to a subject’s foot and automatically calculates spatial and temporal parameters . While convenient, the reliability of the OPTOGait system for the assessment of gait parameters during running has not been studied. The purpose of this study was to examine the validity of spatial and temporal gait parameters calculated by the OPTOGait compared to an instrumented treadmill system during running.
