Abstract
Purpose: to evaluate the electromyographic parameters of swallowing different types of clinical stages of idiopathic Parkinson disease on and off.
Methods: the study was performed at the Clinic of Neurology, Hospital of the Federal University of Pernambuco. The population of the study were 20 patients with Parkinson disease, divided by Unified Scale for Assessment of Parkinson's disease in three groups: flickering, akinetic-rigid and mixed. The surface electromyography examination was collected on suprahyoid muscles during swallowing and 3 ml water and 10 ml of yoghurt, which was repeated 5 times for each volume and consistency. This protocol was carried out before and after the medication period off and on.
Results: it was found that the phase off, akinetic-rigid group had the highest average in parts of swallows and duration of surface electromyography, while the mixed group had the lowest average amplitude. In phase on the three groups tended to improve or maintain the averages of the variables, but there was no significant difference between the clinical types, before or after Levodopa.
Conclusion: drug therapy through Levodopa shows no consistent differences in surface electromyography of swallowing the clinical types of Parkinson disease.

Resumo
Objetivo: avaliar os parâmetros eletromiográficos da deglutição dos diferentes tipos clínicos da doença de Parkinson idiopática nas fases on e off.
Métodos: foram estudados 20 pacientes com doença de Parkinson, divididos através da Escala Unificada de Avaliação da Doença de Parkinson em três grupos: tremulantes, rígido-acinético e misto. O exame de eletromiografia de superfície foi coletado sobre a musculatura supra-hióidea durante a deglutição de 3 ml e 10 ml de água e iogurte, que foi repetida 5 vezes para cada volume e consistência. Este protocolo foi realizado no antes e após a medicação, período off e on.
Resultados: verificou-se que na fase off, o grupo rígido-acinético apresentou as maiores médias de deglutições em partes e duração das eletromiografias de superfície, enquanto que o grupo misto apresentou as menores médias de amplitude. Na fase on, os três grupos tenderam a melhorar ou manter as médias das variáveis estudadas, porém não houve diferença significante entre os tipos clínicos, antes ou depois da Levodopa.
Conclusão: a terapia medicamentosa através da Levodopa não apresenta diferenças consistentes nas eletromiografias de superfície da deglutição dos tipos clínicos da doença de Parkinson.
