Patients with Parkinson's Disease (PD) experience motor and non-motor symptoms that decrease their quality of life. The non-pharmacological management of PD is imperative to improve the quality of life for patients with the disease. Non-pharmacological management options such as exercise, medical, and surgical interventions can improve function and independence in patients with PD. Many non-pharmacological management options target specific symptoms commonly associated with PD. The Knowledge Attitude Practice (KAP) model was adapted to develop a questionnaire that assesses patient and practitioner knowledge of non-pharmacological management options for PD. The questionnaire consisted of 11 questions. To assess the relationship between sociodemographic variables and patient and practitioner knowledge of non-pharmacological management options likelihood-ratio chi-squared, Spearman's correlation, simple logistic regression, and multiple logistic regression analyses were performed on the collected data. Six hundred and forty-one participants completed the questionnaire. For patients (n = 492) and practitioners (n = 149), the most widely known non-pharmacological management option was regular exercise, and the least-known was subthalamotomy. Compared to patients, practitioners were more likely to have knowledge of most non-pharmacological management options (OR 1.73 - 7.36). Higher education level (OR 3.10 - 10.96), younger age (OR 0.09 - 0.32), geographical location (North America OR 0.05 - 0.49, Europe OR 2.24), employment status (OR 4.81 - 12.02), and sex (OR 0.59) had a significant relationship with patient and practitioner knowledge of non-pharmacological management options. Practitioners were more likely to have knowledge of most non-pharmacological management options for PD compared to patients. Several sociodemographic variables impacted one's ability to identify non-pharmacological management options in both populations. Increasing patient and practitioner knowledge of non-pharmacological management options could improve the care and quality of life of patients with PD.
