In “Long-term Effect of Regular Physical Activity and Exercise Habits in Patients With Early Parkinson Disease,” Tsukita et al. reported that regular physical activity, measured by the Physical Activity Scale for the Elderly (PASE) questionnaire, was associated with slower deterioration of postural and gait stability, activities of daily living, and processing speed in patients with early Parkinson disease. Grippe et al. noted that the PASE questionnaire is based on 1-week recall, so it is less reliable than other questionnaires or clinical evaluations of physical activity. They also pointed out that causality in this relationship is unclear because it is possible that postural and gait instability reduces exercise rather than vice versa. Tsukita et al. agreed with these limitations. Both authors emphasized the need for future studies that use other means to evaluate exercise through internet-based applications or other clinical measures.
