Advanced tools provide valid and reliable data, considered very effective for physiotherapy intervention. However, these tools may be limited in clinical usage caused by complicated applicability, inaccessibility, and high cost. Therefore, a video\u2010based system is an alternative choice that is easy and affordable for the clinical setting. The purpose of the study was to evaluate the concurrent validity of the video\u2010based system against the validated instrumented gait system (Force Distribution Measurement [FDM]) on the spatio\u2010temporal gait parameters in individuals with stroke. In addition, the intratester reliability of a novice tester was determined.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Twenty individuals with stroke participated in the study. Gait was captured by the video\u2010based and FDM systems simultaneously to measure the degree of concurrent validity. Parameters composed of the affected and unaffected step lengths (cm) and step time (s), stride length (cm), gait velocity (m\/s), and cadence (steps\/min). Pearson correlation coefficient, paired <jats:italic>t<\/jats:italic> test, and intraclass correlation coefficient (ICC) were used to determine the concurrent validity, the difference of the data, and intratester reliability.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All spatio\u2010temporal gait parameters showed excellent degrees of correlation (<jats:italic>r<\/jats:italic><jats:sub>p<\/jats:sub> = .94 to.99, <jats:italic>p<\/jats:italic> &lt;.001) between the video\u2010based and FDM systems.
