Repercussions of the Degrees of Hearing Loss and Vestibular Dysfunction on the Static Balance of Children With Sensorineural Hearing Loss.

OBJECTIVE: The purpose of this study was to assess the static balance of children with sensorineural hearing loss (SNHL) according to the degrees of SNHL and the function of the vestibular system. METHODS: This cross-sectional study was conducted in public schools located in Caruaru, Pernambuco state, Brazil, with 130 children (65 with normal hearing and 65 with SNHL as documented by air and bone conduction audiometry) of both sexes between 7 and 11 years old. Static balance was assessed by a stabilometric analysis using a force platform consisting of the circular area of center-of-pressure displacement of the children evaluated in 3 positions: bipedal support with feet together and parallel (PF), tandem feet (TF), and 1 foot (OF), carried out under 2 sensory conditions each, with eyes open and eyes closed. After balance assessments, the children with SNHL received examinations of auditory and vestibular functions-through audiometry and computerized vectoelectronystagmography, respectively-to compose the groups according to degrees of SNHL and vestibular function. RESULTS: The children with severe and profound SNHL demonstrated more static balance instabilities than the children with normal hearing in 5 positions assessed with eyes open (PF, TF, and OF) and eyes closed (PF and TF). The same phenomenon occurred in children with SNHL and associated vestibular dysfunction in all of the positions assessed with eyes open and eyes closed (PF, TF, and OF). CONCLUSION: The larger the degree of SNHL, the greater the balance instability of the children. The children with SNHL and associated vestibular dysfunction showed the highest balance instabilities in this study. IMPACT: Children with larger degrees of SNHL and associated vestibular dysfunction might require prolonged periods to rehabilitate their balance.

Efeito em curto prazo de dois protocolos de hidrocinesioterapia em crianças com síndrome congênita associada à infecção do vírus Zika / Short-term effect of two hydrokinesiotherapy protocols of children with Zika congenital syndrome

Objective: To evaluate the short-term effect of two hydrokinesiotherapy protocols on muscle tone and stress levels in children with SCZ. Method: A crossover, randomized, blinded study with children with microcephaly/SCZ between 3-36 months of age. Was evaluated by the Modified Tardieu Scale(EMT), analyzing the degree of muscle tone and the range of articular movement(ROM); the level of stress, through a visual analogue scale of faces ranging from a state without stress(1) to intense stress(4). Two hydrocinesotherapy protocols(PI and PII) were applied in a restricted aquatic environment, for 15 minutes with water temperature at 37ºC. Results: Twelve children participated in the study (mean age in months: 23.9+3.97), 58.7% female. After PI, we observed a reduction in the degree of tone of the extensor muscles of the elbow(p = 0.03) and knee(p = 0.04); in PII, there were no significant changes in the degree of tone. There were no significant changes in the level of stress in PI and PII, however 83.3% were without stress or mild stress before the interventions. Conclusions: Protocol I reduced the degree of muscle tone in the short term when compared to PII. It is emphasized that the protocols applied are of low cost, and can be a viable non-pharmacological technique option in the therapeutic follow-up of these children. It should be noted that the physiotherapist's experience should guide the choice of the appropriate protocol for the therapeutic objective of each child and the advantage of being a technique easily replicable in a therapeutic and home environment.

Análise do desempenho funcional de lactentes com síndrome congênita do zika: estudo longitudinal / Análisis del desempeño funcional de los lactantes con síndrome congénito del zika: estudio longitudinal / Analysis of the functional performance of infants with congenital zika syndrome: a longitudinal study

RESUMO O objetivo do estudo foi avaliar longitudinalmente o desempenho funcional de lactentes acometidos pela síndrome congênita do zika (SCZ). Realizou-se um estudo com lactentes provenientes do Laboratório de Estudos em Pediatria da Universidade Federal de Pernambuco e da Aliança de Mães e Famílias Raras, com idade entre 6 e 24 meses, de ambos os sexos. O Inventário de Avaliação Pediátrica de Incapacidade (PEDI) foi aplicado para análise do desempenho funcional em duas avaliações, com no mínimo seis meses de intervalo. A análise dos dados foi realizada pelo teste de Wilcoxon. Na amostra de 16 lactentes, observou-se que entre as avaliações houve mudança na classificação de normal para atraso nos domínios de autocuidado e função social, com diminuição significativa dos escores normativos (p=0,001 e p<0,001, respectivamente); na mobilidade, os lactentes inicialmente classificados com atraso também apresentaram redução dos escores normativos (p=0,001), mantendo-se na classificação. Apesar do aumento significativo nos escores brutos do autocuidado (p=0,024) e mobilidade (p=0,001), os lactentes continuaram classificados em atraso. Na assistência do cuidador, 100% dos lactentes se encontraram em atraso nos três domínios do PEDI, recebendo assistência máxima ou total. As principais modificações ambientais encontradas foram as centradas na criança. Em suma, os lactentes com SCZ deste estudo apresentaram atrasos significativos no desempenho funcional, com uma evolução lenta no intervalo de tempo avaliado.

RESUMEN El objetivo del estudio fue evaluar longitudinalmente el desempeño funcional de lactantes con síndrome congénito del zika (SCZ). Se realizó un estudio con lactantes de entre 6 y 24 meses, de ambos los sexos, identificados por el Laboratorio de Estudios en Pediatría de la Universidad Federal de Pernambuco y por la Aliança de Mães e Famílias Raras (Alianza de Madres y Familias Raras). Se aplicó el Inventario de Evaluación Pediátrica de Discapacidad (PEDI) para análisis del desempeño funcional en dos evaluaciones, con al menos seis meses de intervalo. El análisis de los datos fue realizado por la prueba de Wilcoxon. En la muestra de 16 lactantes se observó cambio en los campos de autocuidado y función social, de "normal" para "retraso", con disminución significativa de los puntajes normativos (p=0,001 y p<0,001, respectivamente). En la movilidad, los lactantes inicialmente clasificados con retraso también presentaron reducción de los puntajes normativos (p=0,001), manteniéndose en la clasificación. A pesar del aumento significativo en los puntajes netos del autocuidado (p=0,024) y movilidad (p=0,001), los lactantes continuaron clasificados en retraso. En la asistencia del cuidador, un 100% de los lactantes se encontraban en retraso en los tres dominios del PEDI, recibiendo asistencia máxima o total. Las principales modificaciones ambientales encontradas fueron las centradas en el niño. En resumen, los lactantes con SCZ presentaron retrasos significativos en el desempeño funcional, con una evolución lenta en el intervalo de tiempo evaluado.

ABSTRACT This study aimed to longitudinally evaluate the functional performance of infants affected by Congenital Zika Syndrome (CZS). A study was carried out with infants from the Laboratório de Estudos em Pediatria of the Universidade Federal de Pernambuco and the Aliança de Mães e Famílias Raras, aged between 6 and 24 months, of both genders. The Pediatric Evaluation of Disability Inventory (PEDI) was applied to analyze functional performance in two evaluations, with a minimum of six months interval between them. Data analysis was performed using the Wilcoxon test. In the sample of 16 infants, we observed a change in the classification from normal to delay in the domains of self-care and social function, with a significant decrease in normative scores (p=0.001 and p<0.001, respectively); in the mobility, individuals initially classified with delay also presented reduction of normative scores (p=0.001), remaining in the same classification. Despite the significant increase in gross self-care scores (p=0.024) and mobility (p=0.001), infants remained classified as delayed. Caregiver care was analyzed in these evaluation, in which 100% of infants were delayed in all three domains of the PEDI, receiving maximum or full care. The main environmental modifications were those focused on the child. We concluded that infants with CZS presented significant delays in functional performance, with a slow evolution in the evaluated range.
