Physical activity in Parkinson's disease: examining prescription sources, patterns, and the influence of quality of life and disease severity

Limited research has explored the influence of quality of life (QoL) and disease severity on physical activity (PA) in Parkinson's disease (PD) patients, and the sources of PA prescription and advice for this population. This study aims to expand scientific knowledge on these topics. Two-hundred eleven PD patients were personally interviewed to collect data on PA levels using the International Physical Activity Questionnaire-Short Form and QoL using the Parkinson's Disease Questionnaire-8. An ad hoc questionnaire gathered information on disease severity (Hoehn and Yahr stages), PA behaviors, and PA recommendations. Weak but significant associations were found between PA levels, disease severity (r: -0.218; p = 0.004), and QoL (r: -0.244; p = 0.001). Most participants (85%) received PA counselling, predominantly from neurologists, either at diagnosis (52%) or shortly after (28%). Before PD onset, ~86% engaged in PA, decreasing to 66% post-diagnosis. Approximately 78% reported changes in PA, including reduced frequency (18.4%) and duration (32.8%), with walking as the primary activity. Disease severity and QoL significantly affect PA levels in PD patients. Diagnosis is associated with decreased PA frequency and duration, and walking is the preferred activity. Neurologists primarily provide PA advice.
