Electromyographic assessment of swallowing different types of clinical disease, Parkinson's on and off phases

PURPOSE:

to evaluate the electromyographic parameters of swallowing different types of clinical of idiopathic Parkinson disease on and off phases.

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: tremor, 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.
