Development of a new orthopedic insole design for the correction of walking disorders

Modern orthotic insoles often fail to provide the necessary dynamic adaptation to the natural biomechanics of the foot. The rigid designs of traditional models limit physiologic mobility, which can lead to discomfort and progression of deformities. This determines the need to develop new solutions capable of adapting to the individual characteristics of the patient. Purpose of the study — development of an orthopedic insole of a new design for rehabilitation of patients with different types of flat feet. Materials and methods. The study was conducted using a comprehensive approach, including 3D modeling based on radiographic data, biomechanical analysis of load distribution, engineering calculations using CAD-systems, as well as clinical trials involving 163 patients. Podometrics, motiontracking and question2naire methods were used to evaluate the effectiveness. Results. A fundamentally new orthopedic insole design was developed, including five metal guides and a system of dampers. Clinical trials showed that 98 % of patients reported improved walking comfort and 88.9 % improved foot stability. The design provides physiologic load distribution, reducing the impact on the joints and spine. Conclusion. The results obtained confirm the promising application of this development in clinical practice. The development opens new opportunities in orthopedics, combining accurate anatomical support with dynamic correction of movements.
