METHODS OF RESEARCH OF THE STATE OF THE FOOT AND FITNESS OF ITS ARCH FOR LOAD MODES

Abstract

We conducted a comprehensive study and received data characterizing the state and functional readiness of the foot of schoolchildren in terms of its arch flatness in various load modes: with no load, the load of 50 and 100 % of body weight. The study revealed the weakened ligament-muscular apparatus of the foot in the adolescents with the pathology of the musculoskeletal system, i.e. dysplastic scoliosis of degree I (70 S) in all the modes. 25 % of the examined schoolchildren with faults in posture with the arch of the foot in the anatomical state without any load made the so-called «risk group» with individual signs of the state «before flattened foot», i.e., close to the qualitative assessment «flat foot». When the load of the body weight on the foot was 50 %, the flatness index increased up to 85.7 % in girls, 87.5 % in boys with dorsopathy and 10.4-59 % in the school children with the correct posture. The subsequent 100 % increase in the load on the foot was characterized by static deformation of the foot arch in all the examined people, 25 % were diagnosed with «flat foot».
