Abstract Background A study was conducted to determine the reliability and validity of a new foot mobility assessment method that utilizes digital images to measure the change in dorsal arch height measured at 50 of the length of the foot during the Sit-to-Stand test. Methods Two hundred - seventy five healthy participants participated in the study. The medial aspect of each foot was photographed with a digital camera while each participant stood with 50 body weight on each foot as well as in sitting for a non-weight bearing image. The dorsal arch height was measured at 50 of the total length of the foot on both weight bearing and non-weight bearing images to determine the change in dorsal arch height. The reliability
