ABSTRACT Purpose: to characterize the electrical activation of the masseter and suprahyoid muscles at rest and during swallowing tasks, to compare it with clinical aspects of swallowing. Methods: a cross-sectional study, divided into mild osteogenesis imperfecta and moderate-to-severe osteogenesis imperfecta groups. Surface electromyography was performed on the masseter and suprahyoid muscles at rest and during swallowing tasks. The Orofacial Myofunctional Evaluation with Scores assessment form was used to assess clinical aspects of swallowing. Results: moderate-to-severe osteogenesis imperfecta participants presented a higher percentage of masseter activation than mild osteogenesis imperfecta ones. Regarding the clinical aspects of swallowing, the total sample presented 40.9% normal lip occlusion or with slight effort; 59.1% demonstrated tongue protrusion and 50% showed two other signs of atypical function. Furthermore, the higher the score for lip activity during swallowing, the lower the activation of the suprahyoid muscles at rest. Conclusions: the activation of the suprahyoid muscles while swallowing saliva and during consecutive swallows of liquid was similar, and activation during different tasks was higher in the moderate-to-severe osteogenesis imperfecta group. The better the labial myofunctional condition during swallowing, the lower the electrical activation of the suprahyoid muscles at rest.

RESUMO Objetivo Investigar e correlacionar a pressão lingual da região anterior e posterior em contração isométrica e durante deglutição de saliva de indivíduos com osteogênese imperfeita. Métodos Estudo transversal observacional, do qual participaram 22 sujeitos, com média de idade de 12,09 anos, divididos em osteogênese imperfeita leve (tipo 1) (n=15) e osteogênese imperfeita moderada-grave (tipos 3, 4 e 5) (n=7). O Iowa Oral Pressure Instrument foi utilizado e foi aferida a pressão em isometria de língua da região anterior, da região posterior e durante deglutição. As análises estatísticas foram realizadas no programa SPSS, por meio dos testes Mann Whitney, correlação de Spearman e modelo de regressão linear simples. O nível de significância de p<0,05 foi utilizado. Resultados A pressão em isometria de língua foi maior na região anterior do que na região posterior na amostra total e no grupo com osteogênese imperfeita moderada-grave. A pressão da região anterior durante deglutição de saliva foi maior no grupo com osteogênese imperfeita leve. Também foi observada maior pressão de língua da região posterior nesse grupo. Conclusão Maior pressão da região anterior de língua correlaciona-se à maior pressão da região posterior de língua, porém, não há correlação significativa entre a capacidade isométrica de língua e a pressão de língua durante a função de deglutição de saliva. observacional 2 sujeitos 1209 12 09 12,0 anos tipo 1 n=15 n15 n 15 (n=15 moderadagrave moderada grave tipos 3 5 n=7. n7 n=7 . 7 (n=7) SPSS Whitney simples p005 p 0 05 p<0,0 moderadagrave. grave. correlacionase correlaciona se porém 120 12, n=1 n1 (n=1 n= (n=7 p00 p<0, (n= p0 p<0 (n p<

ABSTRACT Purpose To investigate and correlate the lingual pressure of the anterior and posterior region in isometric contraction and during saliva swallowing of individuals with Osteogenesis Imperfecta (OI). Methods This was an observational cross-sectional study, 22 subjects participated, with an average age of 12.09 years, divided into mild OI (OIL) (type 1) (n=15) and moderate/severe OI (OIMG) (types 3, 4 and 5) (n=7). The Iowa Oral Pressure Instrument (IOPI) was used and tongue isometry pressure was measured in the anterior region, posterior region and during swallowing. Statistical analyses was done with the SPSS program using the Mann Whitney test, Spearman correlation and simple linear regression model. The significance level of p<0.05 was used. Results Pressure in tongue isometry was greater in the anterior region than in the posterior region in the total sample and in the OIMG group. The pressure of the anterior region during saliva swallowing was higher in the OIL group. Greater tongue pressure was also observed in the posterior region in the OIL group. Conclusion Greater pressure in the anterior region of the tongue is correlated with greater pressure in the posterior region of the tongue, but there is no significant correlation between the isometric tongue capacity and the tongue pressure during the saliva swallowing function.

RESUMO Objetivos Analisar as publicações científicas sobre audição em indivíduos com osteogênese imperfeita. Estratégias de pesquisa Trata-se de revisão sistemática de literatura. Foram selecionados os descritores Hearing OR Hearing Loss AND Osteogenesis Imperfecta. Duas revisoras consultaram as bases de dados Cochrane Library, PubMed, LILACS, Scopus e Embase. Critérios de seleção utilizaram-se os Descritores em Ciências da Saúde, não sendo delimitado período de publicação dos estudos. Foram critérios de inclusão estudos de coorte, seguimento, transversais, casos controle e em idioma inglês. Foram critérios de exclusão artigos editoriais, relatos/séries de casos, resumos de eventos e estudos conduzidos em animais. Os estudos selecionados foram analisados pela Iniciativa STROBE e pelo Sistema GRADE. Resultados Dos 652 estudos obtidos, foram selecionados 16. A perda auditiva do tipo condutiva foi o tipo mais comum na população com osteogênese imperfeita (OI) e seu início ocorre por volta da segunda década de vida. A definição e a classificação para aferição de perda auditiva, nas publicações com a população com osteogênese imperfeita, apresentaram discordância entre os estudos. Conclusão Esta revisão respondeu às perguntas a que se propôs, constatando que as alterações audiológicas encontradas em pacientes com OI são do tipo condutivo, neurossensorial e misto. Alterações condutivas são mais comuns em pacientes mais jovens e alterações neurossensoriais, em pacientes mais velhos. A Iniciativa STROBE apontou itens descritos de forma parcial e o Sistema GRADE concluiu que os estudos apresentaram alguma falha metodológica.

ABSTRACT Purpose To analyze scientific publications on the hearing issue of patients with osteogenesis imperfecta. Reserch strategy This study is a systematic literature review. The following descriptors were selected “Hearing” OR “Hearing Loss” AND “Osteogenesis Imperfecta”. Two reviewers searched the Cochrane Library, Pubmed, Latin American and Caribbean Health Sciences Literature, Scopus and Embase databases. Selection criteria Descriptors in Health Sciences were used and the publication period of studies was not limited. Inclusion criteria were cohort, follow-up, cross-sectional, and control studies in English language. Exclusion criteria were editorial articles, case reports, case summaries, and animal studies. Selected studies were analyzed by the STROBE Initiative and the GRADE System. Results Of the 652 studies, 16 were selected. Conductive hearing loss is the most common type in the osteogenesis imperfecta (OI) population and its onset is around the second decade of life. Definition and classification for hearing loss measurement in publications with the osteogenesis imperfecta population present disparities among studies. Conclusion This review met the objectives proposed, concluding that audiological alterations found in OI patients are of conductive, sensorineural and mixed types; conductive alterations are more common in younger patients and sensorineural alterations in older ones. The STROBE initiative partially pointed out described items and the GRADE system concluded that studies present some methodological failure.

Introduction Presbycusis is a consequence of aging. Prescription of hearing aids is part of the treatment, although the prevalence of use by elderly people is still small. Objective To verify whether or not self-assessment of hearing is a predictor for purchase of hearing aids. Methods Quantitative, cross-sectional, descriptive, and observational study. Participants were subjects who sought a private hearing center for selection of hearing aids. During the diagnostic interview, subjects answered the following question: On a scale of 1 to 10, with 1 being the worst and 10 the best, how would you rate your overall hearing ability? After that, subjects underwent audiometry, selected a hearing aid, performed a home trial, and decided whether or not to purchase the hearing aid. The variables were associated and analyzed statistically. Results The sample was comprised of 32 subjects, both men and women, with a higher number of women. Mean age was 71.41 ± 12.14 years. Self-assessment of hearing ranged from 2 to 9 points. Overall, 71.9% of the subjects purchased hearing aids. There was no association between scores in the self-assessment and the purchase of hearing aids (p = 0.263). Among those who scored between 2 and 5 points, 64.7% purchased the device; between 6 and 7 points, 76.09% purchased the device; and between 8 and 9 points, 50% purchased the device, respectively. Conclusion There is evidence that low self-assessment scores lead to the purchase of hearing aids, although no significant association was observed in the sample.
