Abstract

OBJETIVO: investigar as diferenças entre os achados eletromiográficos dos músculos supra-hióideos direito e esquerdo durante a deglutição de um líquido e um pastoso fino, em sujeitos idosos com doença de Parkinson e idosos sem doença neurológica. MÉTODOS: 30 sujeitos de ambos os sexos participaram deste estudo, 15 idosos sem doença neurológica e os demais com doença de Parkinson. Todos foram submetidos a um protocolo de avaliação clínica e avaliação eletromiográfica de superfície. RESULTADOS: foram constatadas diferenças significantes nos valores entre os sujeitos (f=14.4 e p= 0.000) e entre os lados (f=4.4 e p=0.0037). Em relação ao tempo de duração da contração muscular durante a deglutição as diferenças foram significantes apenas entre as consistências (f=8.2 e p=0.005). CONCLUSÃO: a amplitude eletromiográfica foi menor nos sujeitos com doença de Parkinson e maior nos músculos supra-hiódeos do lado direito em ambos os grupos. A duração da contração muscular não diferiu significativamente entre os sujeitos com doença de Parkinson e idosos sem doença neurológica e foi menor para a consistência líquida.<br>PURPOSE: to investigate differences between electromyographic samples of right and left suprahyoid muscles during deglutition of thickened liquids and liquid consistencies by elderly people with Parkinson disease and elderly people without any neurological disease. METHODS: 30 subjects, from both genders, took part in this study. Fifteen were elderly without neurological disease whereas the others showed Parkinson disease. All of them were submitted to a clinical evaluation protocol and surface electromyography. RESULTS: significant amplitude difference was found between subjects (f=14.4 and p=0.000) and between sides (t=4,4 and p=0.0037). As for muscular contraction time, the differences were just significant between the consistencies (f=8.2 and p=0.005). CONCLUSION: the electromyographic amplitude was shorter for subjects with Parkinson disease and this amplitude was higher in both groups at the right side. The duration of the muscular contraction did not display significant difference between the subjects with Parkinson disease and elderly without neurological disease. This duration was shorter during the deglutition of liquid consistencies
