Fatigue in Parkinson's disease is not associated with reduced physical activity.
We evaluated whether the self-reported reduction of physical activity associated with fatigue in Parkinson's disease (PD) could be quantified with a wrist-worn activity monitor in 69 non-depressed PD patients. A questionnaire was used to assess the presence of fatigue. Outcome measures reflected activity, immobility and sustained activity above preset thresholds. Thirty PD patients suffering from fatigue did not differ from 39 PD patients (with similar disease severity) who were not suffering from fatigue. These results emphasize the need to explore the role of the mental aspects of fatigue in PD.
