st. Petersburg State University of Industrial Technologies and Design (SPbGUPTD) have developed the world’s only unique laboratory shoe to study the gait pattern of a patient with cerebral palsy and select rehabilitation tools using motion capture technology. As Gazeta.ru was told in the press service of the Priority-2030 program of the Ministry of Science and Higher Education of the Russian Federation, the product has no analogues in the world.
The developed shoe design makes it possible to conduct research on the evaluation and correction of the biomechanical pattern of gait in patients with cerebral palsy and osteogenesis imperfecta. The technique allowed for the first time to assess the height of the arch of the foot, both dynamically and statically, necessary for the accelerated rehabilitation of patients.
For the purpose of a comparative analysis of orthopedic insoles, St. Petersburg State University of Applied Foot Surgery used the Oxford foot model (which most accurately reflects the biomechanics of the movement of various parts of the foot during walking).
“The foot is a complex structure with many joints that allow a person to move. Using the Oxford model, we can evaluate the four parts of the foot and calculate the true angle of the ankle, i.e. the movement of the heel bone relative to the shinbone. This is the only technique that allows you to evaluate the height of the arch of the foot both dynamically and statically, ”says Andrei Aksenov, head of the St.
Scientists recreate the movements of human joints and skeleton using reflective markers. They are installed at specific anatomical points of the patient’s body and reflect infrared radiation, after which the skeleton is reconstructed, the data is analyzed and interpreted.
Currently, scientists are making a sample of the system that will be tested in SPbGUPTD with the participation of orthopedic doctors. The resulting technology will enable orthopedists to see, for the first time, changes in biomechanical parameters of gait, movements of body parts, and joint kinetics due to changes in footpad design, height height, rolling lines, and other factors.
