Al-Kharaz, Ali and Chong, Albert (2019) 3D Video Images for Comparing Indian and Iraqi Women’s Foot Width Surface Shape Associated with Stance Phase of Gait. In: 2nd International Conference on Information Science and System (ICISS 2019), 16-19 March, 2019, Tokyo, Japan.
Abstract
As the foot is a flexible structure, foot shape changes with gait. Seven-video images captured with smartphones and photogrammetric techniques were used to generate precise three dimensional foot surfaces in the stance phase (heel-strike, midstance and toe-off) of a gait cycle for women walking on a platform. In this study, six healthy women (3 Iraqi and 3 Indian) walked barefoot at their comfortable speed. The study compared foot width parts (forefoot, midfoot and rearfoot) during the stance phase of gait cycle to gather essential information for footwear manufacture that takes into consideration foot shape changes during walking. The study showed that forefoot for all subjects is wider than other parts in heel-strike, and noted slight variations of foot width between Iraqi and Indian women during walking.
