Reliability and Validity of a Questionnaire to Assess Swallowing Disorders in Parkinson's Disease Cases

Abstract

Introduction: Swallowing problems have significant subjective component. Their evaluation necessitates the use of questionnaires to know both extent of symptoms and effect on quality of life. These should be designed to get maximum information with minimum trouble to the patient. Parkinson's disease (PD) involves swallowing disorder as a symptom, often unreported. Hence, this needs to be assessed separately.
