Summary
Background. The auditory system participates in coordinating the actions of the postural muscles. That is why hearing problems can have a negative effect on body posture. The aim of the research presented here was to discover how often defective posture occurs among deaf children and adolescents and to determine what type of defective posture occurs most often.
The research involved 54 deaf children and adolescents aged 10 to 16 (24 girls and 30 boys). Body posture examination was based on photometric Moire method which allowed us to create points of body posture asymmetries and to create the range of kyphosis and lordosis in a standing position.
Defective posture occurs in 100% of the tested children and adolescents in the sagittal plane and/or in the frontal plane. The deaf children and adolescents had scoliotic defect of posture and/or different defect posture in the sagittal plane. Rounded back (hyperkyphosis) is the most frequent type of this defect posture.
The obtained results lead to the conclusion that deaf children and adolescents require careful observation and control regarding defective posture and should be covered by prophylactic and correction programmes.
