Lower limb flexibility assessment using photogrammetry

We aimed to verify the intrarater and interrater reliability of photogrammetry in the assessment of iliopsoas, hamstring, quadriceps and gastrocnemius muscle on two occasions. This data shows range of motion change in degrees, which was measured using photogrammetry by three novice raters. In order to analyze intrarater reliability, rater 1 analyzed the images of the same assessment day twice (gray cells in the data set). Participants were healthy, physically active adults.
