Introduction:Posture is determined by the performance of the visual, somatosensory and vestibular systems. Children with hearing loss can present problems in their posture or postural control, enabling postural deviations and alterations to appear in their vertebral column, possibly provoked by a hypoactivity of the vestibular system as a result of deafness. Objective:To evaluate the posture of the vertebral column in children and teenagers with hearing loss at school age, taking into consideration the sample gender and age. Method:A descriptive and prospective study was performed at both Duque de Caxias School and Rotary Rehabilitation and Special Education Center in Caruaru -Pernambuco. 44 students aged between 7-17 years old, out of whom 22 were female and 22 were male, with hearing loss were evaluated. The study was developed by way of a postural evaluation, using a symmetrograph, marking specific anatomical points with stickers placed over polystyrene balls and fixed with double-sided adhesive tape. Results:The results showed that all of the individuals evaluated in this study presented some kind of postural alteration in their vertebral column. Scoliosis was the most observed alteration among the students (84.1%), followed by thoracic hyperkyphosis (68.2%). Conclusion:It has been concluded that children and teenagers with hearing loss are exposed to postural alteration in their vertebral column. Such a condition can be associated with a number of factors comprising unfavorable ergonomics of the school environment, bad postural habits and impairment of the vestibular system by virtue of the hearing loss.

Introduction Head sense position is coordinated by sensory activity of the vestibular system, located in the inner ear. Children with sensorineural hearing loss may show changes in the vestibular system as a result of injury to the inner ear, which can alter the sense of head position in this population. Aim Analyze the head alignment in students with normal hearing and students with sensorineural hearing loss and compare the data between groups. Methods This prospective cross-sectional study examined the head alignment of 96 students, 48 with normal hearing and 48 with sensorineural hearing loss, aged between 7 and 18 years. The analysis of head alignment occurred through postural assessment performed according to the criteria proposed by Kendall et al. For data analysis we used the chi-square test or Fisher exact test. Results The students with hearing loss had a higher occurrence of changes in the alignment of the head than normally hearing students (p < 0.001). Forward head posture was the type of postural change observed most, occurring in greater proportion in children with hearing loss (p < 0.001), followed by the side slope head posture (p < 0.001). Conclusion Children with sensorineural hearing loss showed more changes in the head posture compared with children with normal hearing.

INTRODUÇÃO: A postura é determinada pela atuação dos sistemas visual, somatossensorial e vestibular, situado na orelha interna. Crianças com perda auditiva sensório-neural podem apresentar problemas na regulação do controle postural, favorecendo o surgimento de desvios e alterações posturais na coluna vertebral, provocados, possivelmente, pela hipoatividade do sistema vestibular, em decorrência da lesão na orelha interna. OBJETIVOS: Identificar e comparar a distribuição de alterações posturais na coluna vertebral em escolares surdos e ouvintes na faixa etária entre 7 e 17 anos. MATERIAIS E MÉTODOS: Este estudo analítico, observacional, de corte transversal analisou a postura da coluna vertebral de 44 escolares com perda auditiva sensório-neural e 44 escolares ouvintes, de ambos os gêneros. O estudo foi desenvolvido por meio de uma avaliação postural, com o uso de um simetrógrafo, segundo os critérios propostos por Kendall et al. RESULTADOS: Observou-se uma maior ocorrência de alterações posturais nos escolares surdos, se comparados aos ouvintes (surdos: 100%; ouvintes: 84,1%), p = 0,012. A escoliose foi a alteração postural mais observada em ambos os grupos (surdos: 84,1%; ouvintes: 59,1%), p = 0,009, seguida da hipercifose torácica (surdos: 68,2%; ouvintes: 45,5%), p = 0,031. CONCLUSÃO: Os escolares surdos apresentaram uma probabilidade ainda maior quando comparados aos escolares ouvintes de desenvolver alterações posturais na coluna vertebral. Tal condição pode ter relação com o acometimento do sistema vestibular, em decorrência da lesão na orelha interna, de maus hábitos posturais em atividades diárias e da ergonomia desfavorável do ambiente escolar.
