The Unified Parkinson’s Disease Rating Scale (UPDRS) is used to track disease severity in veterans with Parkinson disease (PD). Ideally, doctors would have a full range of objective functional capacity measures on which to base decisions, but time and resources limit what can be done in the clinical setting. For this reason, easier-to-use rating instruments like the UPDRS are widely applied. A key remaining question is how well the UPDRS tracks objective measures of functional performance. Our study comparing UPDRS with measures of functional capacity in 70 mild to moderately impaired PD participants showed a weak relationship with ambulatory function and no relationship with peak aerobic capacity.
