RESUMEN
Abstract Introduction Deep brain stimulation (DBS) is an established treatment for Parkinson's disease (PD). However, there is little evidence regarding the effect of DBS on dysphagia. Objective To assess the swallowing and quality of life of individuals with PD before and after DBS surgery. Methods Our sample consisted of people who had undergone DBS surgery in a referral hospital in the state of Rio Grande do Sul, Brazil. The inclusion criteria were a diagnosis of PD and having undergone DBS surgery. A cognitive screening, through a questionnaire about depression and quality of life, was conducted. Evaluations of each patient's swallowing were performed before and after surgery. The assessment consisted of anamnesis, clinical assessment, the Functional Oral Intake Scale, clinical evaluation of swallowing, and the Hoehn and Yahr scale. Results The sample included 10 individuals, all male, with a mean age of 57.3 years (±4.7), a mean disease duration of 13.0 years (±2.4), and mean level education of 8.1 years (±4.0). In the clinical evaluation of the swallowing, a significant improvement after DBS was not observed. However, little changes in the signs and symptoms of dysphagia that had a positive impact on the quality of life were observed. Furthermore, there was no relation between the patients' motor subtype and swallowing pre- and post-DBS. Conclusion There was an improvement in the quality of life of the patients after DBS. However, the improvement in the clinical signs and symptoms of dysphagia did not cause an overall improvement in the swallowing function.
RESUMEN
RESUMO Objetivo: traduzir e adaptar culturalmente para o português brasileiro o Swallowing disturbance questionnaire (SDQ) para detecção de risco de disfagia em indivíduos com Doença de Parkinson (DP). Métodos: realizou-se tradução para o português, retradução para o inglês, análise de confiabilidade do instrumento, sendo a versão final aplicada aos participantes e realizado o reteste após duas semanas. Selecionou-se os participantes em um ambulatório de distúrbios do movimento de um hospital de referência no Rio Grande do Sul. Incluiu-se indivíduos com diagnóstico de DP. Excluiu-se indivíduos com alteração de linguagem ou audição que impossibilitasse a compreensão do questionário e com diagnóstico de outras doenças neurológicas. Resultados: a amostra foi composta por 23 indivíduos. Os participantes responderam a todas as questões. Não houve eliminação de nenhuma questão. Na análise da confiabilidade teste-reteste o coeficiente de correlação intraclasse do escore final nos dois momentos foi de 0,912 com p<0,001 (95%IC=0,792-0,963), demonstrando que os dados são altamente homogêneos. Na análise por questão, não houve diferença significante entre os dois momentos de aplicação. O valor de α de Cronbach do instrumento foi de 0,63. Conclusão: houve equivalência cultural do SDQ para o português brasileiro, com boa confiabilidade interna do instrumento.
ABSTRACT Purpose: to translate and culturally adapt to Brazilian Portuguese Swallowing the disturbance questionnaire (SDQ) for dysphagia detection risk in individuals with Parkinson's disease (PD). Methods: this was translated into Portuguese, back-translation into English, instrument reliability analysis, the final version applied to participants and conducted retesting after two weeks. It was selected participants at a clinic for movement disorders of a reference hospital in Rio Grande do Sul. It was included individuals diagnosed with PD. It was excluded individuals with impaired speech or hearing that prevented the understanding of the questionnaire and diagnosis of other neurological diseases. Results: the sample consisted of 23 individuals. The participants answered all questions. There was no question of disposal. In the analysis of test-retest reliability intraclass correlation coefficient of the final score in the two periods was 0.912 with p <0.001 (95% CI = 0.792 to 0.963), demonstrating that the data are highly homogeneous. In the analysis by question, there was no significant difference between the two application times. The value of α Cronbach instrument was 0.63. Conclusion: there was cultural equivalence of the SDQ for Brazilian Portuguese, with good internal reliability of the instrument.
