title: Urinary dysfunction and motor symptoms in untreated Parkinson's disease.
abstract: OBJECTIVE
  The aim of the present study was to determine the associations of motor symptoms in untreated Parkinson's disease (PD) with urinary dysfunction. We therefore examined the association between the overactive bladder symptom score (OABSS) and Unified Parkinson's Disease Rating Scale (UPDRS).
  
  
  METHODS
  Thirty-one untreated PD patients without dementia (12 men and 19 women with a mean age of 72.0±6.7years) were included in this study. Their urinary tract dysfunctions were rated using the OABSS. The motor symptoms of all patients were also assessed using UPDRS.
  
  
  RESULTS
  OABSS had significant correlations with UPDRS motor score (Spearman's rho=0.39, p=0.03) and akinetic-rigid score (Spearman's rho=0.47, p=0.01). However, OABSS showed no significant correlation with tremor score, age, or duration of PD.
  
  
  CONCLUSIONS
  Higher OABSS was consistently associated with increase in severity of motor disorders, especially akinetic-rigid score, in the study participants.
