Higher scores were associated with younger age and male sex. Only 47% of PD subjects and 44% of HC reported activity consistent with standard recommendations for adults.Our findings highlight the need to encourage exercise even in early PD.Disease progressionParkinson Progression Markers InitiativeParkinson diseasephysical activityPhysical Activity in Early Parkinson Disease.Journal article2018-08-23
