title: Postural instability and falls are more frequent in Parkinson's disease patients with worse trunk mobility.
abstract: OBJECTIVE
  Correlate the occurrence of falls and the activity of rolling over in bed with performance on the Trunk Mobility Scale (TMS) in patients with PD, and determine whether this instrument score can predict the risk of falls.
  
  
  METHODS
  This is a cross-sectional study. Assessed patients reported the frequency of falls in the previous year and whether they had difficulties rolling over in bed. Then, the following scales were applied: TMS, Hoehn and Yahr, Unified Parkinson's Disease Rating Scale-III and Schwab and England Activities of Daily Living.
  
  
  RESULTS
  Eighty-five patients were analyzed. Patients with a history of falling showed worse performance in the TMS (p < 0.01). There is a significant correlation between TMS and the activity of rolling over in bed (p < 0.01).
  
  
  CONCLUSIONS
  PD fallers present worse scores in TMS, and there is a significant correlation between difficulty rolling over in bed and TMS score.
