Abstract

Background. Hearing dysfunction can have a negative effect on body posture. The physical and motor development in deaf and partially hearing children can also be different then their contemporaries. This can influence on process of posture’s genesis. The aim of the study was to estimate and compare body posture’s asymmetries in deaf and partially hearing with a normal group of children between the ages of 8- to 13- years. Material and methods. The experimental group consisted of 63 girls and 90 boys with hearing dysfunction. The control group included 162 girls and 140 boys from primary schools of Silesia. Body posture examinations were based on Moire’s technique and then were given points for asymmetries of body posture. The estimation of body posture contained trunk’s inclination in frontal and sagittal plane, position of the vertebrae spine, shoulders, scapulas, pelvis and waist arrangement. Results. The children with hearing dysfunctions had more asymmetries in the frontal and transversal planes and more imperfect position of the vertebrae spine than the control group. Defects of the thorax were more frequent in that deaf and partially hearing children. Total points for body posture also showed that deaf and partially hearing children had worse body posture in frontal plane. Conclusions. This study finds that the loss of hearing or considerable decrease of hearing can be essential for body posture.
