The correct posture of students is conditioned by a multitude of factors. The spine is the axis around which the other body segments are positioned for a harmonious body. The purpose of this study is to identify the incidence of spinal deviations at students with sensory hearing impairments selected in the physical therapy program conducted in special schools in Bucharest. We wanted to find out if there are statistical differences between the two categories of subjects (with mild/moderate deficiencies and with poor/severe/deep and/or associated deficiencies) related to the incidence of deformities/deviations in the spine. The research sample was composed of 216 students enrolled in special education in Bucharest. The criteria for forming the working groups were: hearing impairment, degree of disability, gender and level of education (primary or secondary). Conclusions. The incidence of the disease is different in students with hearing impairments enrolled in primary and secondary education. For students with poor/severe/profound hearing impairment, the most common condition is lordosis followed by kypholordosis and neurological disorders.
