ABSTRACT

Abstract Objectives: Decreased Sound Tolerance (DST) is a negative reaction to a sound that does not cause any reaction in an individual with normal hearing. DST's subclasses include hyperacusis, phonophobia, and misophonia, which are distinct and have therapy variations. There is no diagnostic method or scale that distinguishes them in the literature. This study's purpose was to develop a screening scale that distinguishes these three DSTs. Methods: The study comprised 257 willing participants with normal hearing. Cronbach alpha coefficient, item-total correlation, and item differentiation of the Decreased Sound Tolerance Scale-Screening (DSTS-S) were evaluated. Structural validity of DSTS-S was performed by Varimax rotation with Kaiser normalization using Explanatory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA) was performed to assess its structural compatibility. The scale's total scores from each section were compared using the Mann-Whitney U test in symptom (+) and symptom (-) participants. Results: The Cronbach alpha value for hyperacusis, phonophobia, and misophonia sections of DSTS-S was calculated as 0.881, 0.775, and 0.938, respectively. The difference between the independent samplet-test and the variables was statistically significant (p<0.01). The Mann-Whitney U test showed a significant difference between the median values of the total groups 'scores with and without hyperacusis, phonophobia, and misophonia (HTS, PTS, and MTS, respectively) (p<0.05). Evaluation by ROC analysis showed that hyperacusis was useful in predicting the presence of hyperacusis, phonophobia was useful in predicting the presence of phonophobia, and misophonia was useful in predicting the presence of misophonia (p< 0.001). Hyperacusis and misophonia sections showed high reliability, and phonophobia section showed a moderately reliable level. The Kappa test showed that the compatibility between test-retest for the total scores was statistically significant (p < 0.001). Conclusion: The study's results indicated that DSTS-S is a valid and reliable scale for identifying subtypes/problems/classes of decreased sound tolerance.

ABSTRACT

Abstract Introduction: Attention deficit hyperactivity disorder is a common impairing neuropsychiatric disorder with onset in early childhood. Almost half of the children with attention deficit hyperactivity disorder also experience a variety of motor-related dysfunctions ranging from fine/gross motor control problems to difficulties in maintaining balance. Objectives: The main purpose of this study was to investigate the effects of distractors two different auditory distractors namely, relaxing music and white noise on upright balance performance in children with attention deficit hyperactivity disorder. Methods: We compared upright balance performance and the involvement of different sensory systems in the presence of auditory distractors between school-aged children with attention deficit hyperactivity disorder (n = 26) and typically developing controls (n = 20). Neurocom SMART Balance Master Dynamic Posturography device was used for the sensory organization test. Sensory organization test was repeated three times for each participant in three different test environments. Results: The balance scores in the silence environment were lower in the attention deficit hyperactivity disorder group but the differences were not statistically significant. In addition to lower balance scores the visual and vestibular ratios were also lower. Auditory distractors affected the general balance performance positively for both groups. More challenging conditions, using an unstable platform with distorted somatosensory signals were more affected. Relaxing music was more effective in the control group, and white noise was more effective in the attention deficit hyperactivity disorder group and the positive effects of white noise became more apparent in challenging conditions. Conclusion: To the best of our knowledge, this is the first study evaluating balance performance in children with attention deficit hyperactivity disorder under the effects of auditory distractors. Although more studies are needed, our results indicate that auditory distractors may have enhancing effects on upright balance performance in children with attention deficit hyperactivity disorder.


Resumo Introdução: O transtorno do déficit de atenção e hiperatividade é um distúrbio neuropsiquiátrico comum que causa comprometimentos, com início na primeira infância. Quase metade das crianças com transtorno do déficit de atenção e hiperatividade também experimenta uma variedade de distúrbios relacionados às habilidades motoras, desde problemas de controle de habilidades motoras finas/grossas até dificuldades na manutenção do equilíbrio. Objetivos: O principal objetivo deste estudo foi investigar os efeitos de distrações, especificamente duas distrações auditivas diferentes, música relaxante e ruído branco, sobre o desempenho do equilíbrio vertical em crianças com transtorno de déficit de atenção e hiperatividade. Método: Comparamos o desempenho do equilíbrio vertical e o envolvimento de diferentes sistemas sensoriais na presença de distração auditiva entre crianças em idade escolar com transtorno do déficit de atenção e hiperatividade (n = 26) e controles com desenvolvimento típico (n = 20). O dispositivo Neurocom Smart Balance Master Dynamic Posturography foi utilizado para o teste de organização sensorial. O teste de organização sensorial foi repetido três vezes para cada participante em três ambientes de teste diferentes. Resultados: Os escores de equilíbrio no ambiente em silêncio foram menores no grupo com transtorno do déficit de atenção e hiperatividade, mas as diferenças não foram estatisticamente significativas. Além dos escores de equilíbrio mais baixos, as razões vestibulares e visuais também foram menores. As distrações auditivas afetaram positivamente o desempenho do equilíbrio geral para ambos os grupos. Condições mais desafiadoras, usando uma plataforma instável com sinais somatossensoriais distorcidos, foram mais afetados. Música relaxante foi mais eficaz no grupo de controle, e ruído branco foi mais eficaz no grupo de hiperatividade com déficit de atenção e os efeitos positivos do ruído branco se tornaram mais evidentes em condições desafiadoras. Conclusão: Que seja de nosso conhecimento, este é o primeiro estudo que avalia o desempenho do equilíbrio em crianças com transtorno do déficit de atenção e hiperatividade sob os efeitos de distrações auditivas. Embora mais estudos sejam necessários, os nossos resultados indicam que as distrações auditivas podem ter efeitos de aumento no desempenho do equilíbrio vertical em crianças com transtorno de déficit de atenção e hiperatividade.

ABSTRACT

ABSTRACT INTRODUCTION: Keeping balance of the upright stance is a highly practiced daily task for healthy adults and is effectively performed without overt attentional control in most. OBJECTIVE: The purpose of this study was to examine the influence of concurrent cognitive tasks on postural sway in healthy participants. METHODS: This was a prospective study. 20 healthy volunteer subjects were included. The cognitive and balance tasks were performed separately and then, concurrently. Postural control task consisted of 6 conditions (C) of the Sensory Organization Test. The cognitive task consisted of digit rehearsal task of varying presentation and varying levels of difficulty. RESULTS: A statistically significant difference was noted between dual task and no task for C1, C2, C3 and C4 Sensory Organization Test scores ( p < 0.05). There was no statistically significant difference between dual task versus non-task for C5, C6 and combined Sensory Organization Test scores ( p > 0.05). CONCLUSION: During dual task, increase has been determined in postural sway for C1, C2, C3 and C4 for all presentation modes and difficulty levels of the cognitive tasks.


RESUMO INTRODUÇÃO: Manter o equilíbrio na postura vertical é uma tarefa cotidiana constantemente praticada por adultos saudáveis, e é efetivamente realizada pela maioria sem a necessidade de um controle atencional. OBJETIVO: A finalidade deste estudo foi examinar a influência de tarefas cognitivas concomitantes no equilíbrio postural de indivíduos saudáveis. MÉTODO: Trata-se de um estudo prospectivo em que participaram 20 voluntários saudáveis. As tarefas cognitivas e de equilíbrio foram realizadas separadamente; e em seguida, realizadas simultaneamente. A tarefa de controle postural consistiu em seis condições (C) do Teste de Organização Sensorial (TOS). A tarefa cognitiva consistiu na repetição de dígitos com apresentações variadas e vários níveis de dificuldade. RESULTADOS: Houve diferença estatisticamente significante entre os escores do TOS para as condições C1, C2, C3 e C4 para "dupla tarefa" vs. "não tarefa" (p < 0,05). Não houve diferença estatisticamente significante entre os escores do TOS para as condições C5 e C6 e para a combinação dos escores do TOS para "dupla tarefa" vs. "não tarefa" (p > 0,05). CONCLUSÃO: Durante a realização de dupla tarefa, foram determinados aumentos na oscilação postural para as condições C1, C2, C3 e C4 para todos os modos de apresentação e níveis de dificuldade das tarefas cognitivas.

ABSTRACT

Quedas representam um importante problema de saúde entre a população idosa. Aproximadamente um terço dos idosos acima de 65 anos de idade sofrerão uma ou mais quedas por ano. OBJETIVO: Avaliar o equilíbrio entre idosos que caem e aqueles que não sofrem queda. Desenho do estudo: clínico. MÉTODOS: Investigamos 30 indivíduos com mais de 65 anos de idade. 15 haviam sofrido queda em um período de um ano (Grupo I) e 15 não tinham passado de quedas (Grupo II). Comparamos os valores da Posturografia Dinâmica Computadorizada (PDC); Teste de Organização Sensorial (TOS); Limites de Estabilidade (LE); Deslocamento Ponderal Rítmico (DPR) e Escala de Equilíbrio de Berg (EEB) entre os indivíduos dos grupos I e II. RESULTADOS: Os valores de TOS 3, 6 e composto, EEB e escore de velocidade no eixo direita-esquerda do DPR foram significativamente menores no Grupo I e determinamos o TOS 4, 5, 6, composto e EEB do grupo II (p < 0,05). CONCLUSÃO: Os valores de PDC e EEB em idosos que sofrem quedas estiveram significativamente mais baixos quando comparados àqueles que não caíram.


Falls present a substantial health problem among the elderly population. Approximately one-third of community-dwelling people over 65 years of age will experience one or more each year. OBJECTIVE: The purpose of this study was to evaluate balance between fallers and non-fallers elderly. Study Design: Clinical study. METHODS: We studied 30 subjects older than 65 years of age. 15 subjects had a history of falls within a year (Group I) and 15 subjects had no history of falls (Group II). The scores of Computerized Dynamic Posturography (CDP); Sensory Organization Test (SOT), Limits of Stability (LOS), Rhytmic Weight Shift (RWS) and Berg Balance Scale (BBS) findings gathered from the individuals from Group I and Group II, were compared. RESULTS: The SOT 3, 6, composite, BBS scores and left-right on-axis velocity score of RWS test of the Group I were found to be significantly lower the Group II (p < 0.05). A positive correlation between the SOT 3, 5, composite and BBS scores of Group I and the SOT 4, 5, 6, composite and BBS scores of Group II is determined (p < 0.05). CONCLUSION: The CDP and BBS scores in fallers were found to be significiantly lower as compared to the non-fallers elderly.
