Surface electromyography of muscle involded deglutition in patients with Parkinson's disease

Abstract

BACKGROUND: Parkinson’s disease (PD) is a chronic degenerative disease of the central nervous system resulting from the death of motor neurons in the substantia nigra promoting motor disorders and postural dysfunctions. Parkinson’s disease is a neurological disease that most often results in difficulty in swallowing (dysphagia). The incidence of dysphagia in PD is between 50% and 100% of patients and may be present even in the absence of clinical symptoms […] Surface electromyography of muscle involded deglutition in patients with Parkinson’s [...]
