Hearing impairment is considered one of the most common inherited impairments and occurs in 1 to 3 out of a thousand newborn babies and, besides causing inability for a child to communicate with the world, has a great effect on the emotional, social and motor development of a child. Existing research on motor development of children with cochelear implant are few and mostly the topic of those research was balance, while smaller number of researches dealt with just a portion of a wide range of motor abilities of children with cochelear implant and their findings are contradictory. Aim of the research was to examine the differences in kinanthropological characteristics between groups of students with cochelear implant, in respect to different etiology of hearing impairment and students without hearing impairment. Furthermore, research was also aimed to determine differences between above mentioned groups, based on sex, age, additional kinesiological activity and age of cochlear implantation. The research included a total of 70 students without hearing impairment and 70 subjects with cochelear implant, ages 6 to 18, who have been included in regular elementary or secondary educational system in the Republic of Croatia. Subject group with cochelear implant has been additionally divided based on the etiology of hearing impairment into two groups – subjects with acquired hearing impairment (n:33) and subjects with inherited hearing impairment (n:37). Second version of the Bruininks-Oseretsky Test of Motor Proficiency was used for determining motor skills. Control variables are age, sex age when the hearing impairment occurred, age of cochlear implantation and participation in additional physical activity outside regular PE classes and etiology of hearing impairment. Results of this research suggest that students with cochelear implant of different hearing impairment etiologies have not only significantly less developed balance, as it was observed by the previous research, but also fine and gross motor skills as a whole in contrast to students without hearing impairment. In view of hearing impairment etiology, it has been determined that students with cochelear implant and acquired hearing impairment have a significantly more expressed deficit in a larger number of measured motor skills than students with inherited hearing impairment. In addition, it has been observed that the same group of students with acquired hearing impairment, with respect to additional physical activity, did not show growth in motor skills. Everything stated supports the conclusion that in cases of hearing impairment, the development of motors skills in children is still somewhat weaker.
