Abstract: Gait analysis is the study of body mechanics to assess individualâ€™s ability to walk. Foot ulcer may occur for various reasons, peripheral neuropathy being one of them, is a main reason for non-traumatic lower limb amputation. Main objective of our project was to study the gait pattern of individuals for differences in Ground Reaction Force value in accordance with their BMI using android mobile application to check the possibility of foot ulceration. The gait was recorded and analyzed using Diafoot, our mHealth application. To suffice the research domain of this case study, smartphone with the application was attached to the lower thigh of the subject. The subject was asked to walk a fixed distance of 8m and the developed application recorded acceleration, speed, step count, Body Mass Index and Ground Reaction Force. Our study showed that the Ground Reaction Force values of the underweight, normal, overweight and obese individuals showed significant differences, with which we found that it is practicable to predict the possibility of foot ulceration using Ground Reaction Force value since it will eventually impact the foot plantar tissue
