An attempt to identify significant correlations between parameters of body trunk and parameters of feet and their frequency in adolescents aged 14-18 years Mrozkowiak Mirosław Physiotherapy Office, Poznań, Poland Abstract Introduction. All disorders are temporary as a natural consequence of ontogenetic processes usually disappearing after puberty. Therefore, it is important to provide incentives in this period in order to maintain physical activity at a previously achieved level and try to shape the parameters of feet through exerting a conscious influence on body trunk parameters. Material and method. The study conducted with the group of adolescents aged 14 to 18 years enabled to record 2,343 observations with regard to the measurement of 90 parameters describing trunk and feet. The station for an assessment of body posture and feet using the photogrammetric method consisted of a computer, a card, software, a display monitor, a printer and a projection-reception device with a camera to measure the selected parameters. Conclusions The values of frontal and sagittal body trunk parameters revealed a significant correlation with the parameters of feet. An increased frequency of these correlations was observed between the sagittal parameters of body trunk and feet. The relationship between transverse parameters was much less significant. Feet parameters most often significantly correlated with: trunk flexion angle in the sagittal plane, height of thoracic kyphosis, angle of the projection line of lower scapula angles with the right or the left angle being more convex, lumbar lordosis length, asymmetry in the height of scapula triangles with the right scapula up, inclination of the thoracic and lumbar spine, shoulders line angle with the left one up and the angle of pelvic flexion to the right in the transverse plane. Feet parameters with which trunk parameters most frequently correlated included: width of longitudinal arch 1, length of longitudinal arch 2 in the right foot, varus angle of the fifth toe and width of the right foot and length of the first arch in the left foot and length of the right and left foot. Key words: correlation, spine, pelvis, feet
