The accomplished scientific and technical project is aimed at preserving children’s health. School age is a period of ontogenesis, when various types of impaired posture are clearly manifested. According to statistics, 10-40% of school-age children show signs posture faults. The project solves a complex of interdisciplinary applied problems of posture correction and flatfoot diagnosis, taking into account the interdependence of posture disorders and foot deformities. The project is done at the intersection of human physiology, rehabilitation science, and electronic engineering. A hardware-software complex including a combined posture corrector for teenagers and a stop-meter detecting signs of flatfoot is developed. Several models of the device are produced and tested.
