Abstract(s)
A doença de Parkinson (DP) é uma patologia neurodegenerativa que leva a alterações do padrão da marcha (como velocidade lentificada, hipocinesia, festinação e freezing), diminuindo a qualidade de vida com aumento do risco de queda e da mortalidade. Como tal, seria pertinente avaliar a progressão dos parâmetros da marcha nestes indivíduos. A Functional Gait Assessment (FGA) tem mostrado ser um instrumento válido e fidedigno na avaliação da marcha e do equilíbrio na DP. O objetivo do estudo é contribuir para a validação da FGA para português e para a DP. Este estudo pretende fornecer uma ferramenta para a avaliação clínica dos utentes em
causa e promover o treino da marcha. Após a tradução e retroversão por dois tradutores bilingues, obteve-se a versão portuguesa do FGA. A amostra incluiu 32 participantes com DP idiopática, de três instituições. Procedeu-se à realização da análise psicométrica da FGA, que incluía a verificação da consistência interna e inter-avaliador. O valor do alfa de Cronbach obtido para a pontuação final da FGA para o avaliador A foi de 0,87 e para o avaliador B foi de 0,90. Obteve-se um coeficiente de correlação intraclasse (CCI) para a pontuação final da FGA de 0,96 com intervalo de confiança (IC) de 95% entre 0,93 e 0,98. A FGA demonstrou no presente estudo uma boa consistência interna e fidelidade inter-avaliador para medir a evolução do equilíbrio e das alterações do padrão de marcha na DP.
ABSTRACT - Parkinson's disease (PD) is a neurodegenerative pathology that leads to gait pattern changes (slowed speed, hypokinesia, festination, and freezing), decreasing the quality of life and therefore increasing the risk of falls and mortality. As such, it would be pertinent to evaluate the progression of gait parameters in these individuals. The Functional Gait Assessment (FGA) has been shown to be a valid and reliable tool in the assessment of gait and balance in PD. The objective of the study is to contribute to the validation of the FGA for the Portuguese language and for PD. This study intends to provide a tool for the clinical evaluation of these patients and to promote gait training. After the translation and retroversion by two bilingual translators, the Portuguese version of the FGA was obtained. The sample included 32 participants with idiopathic PD, from three institutions (Associação Portuguesa de Doentes de Parkinson, Clínica Prinovhelp, and Policlínica Parque da Paz). The psychometric analysis of the FGA was performed, including verification of internal consistency and inter-rater reliability. The value of Cronbach's alpha obtained for the final score of the FGA for the evaluator A was 0.87 and for the evaluator B, it was 0.90. An intraclass correlation coefficient (ICC) was obtained for the final GAF score of 0.96 with a 95% confidence interval (CI) between 0.93 and 0.98. The FGA showed in the present study a good internal consistency and inter-rater reliability to measure the evolution of balance and gait pattern changes found in the PD.
