Risk of falling in Parkinson's disease patients

from Kerr et al. Neurology 2010; 75: 116=124

Authors looked at 101 independently living patients without walking aids and put various factors through a computer to predict risk of falling.  The factors that increased the risk include

  • dyskinesias
  • symptomatic orthostasis
  • sleep disturbance
  • Tinetti, Berg, and TUG (timed up and go) measurements
  • poor peripheral sensation and knee extension strength and greater a-p sway when standing on firm surface
  • UPDRS total score and FOG (freezing) questionnaire
  • For previous nonfallers, key measurement was A-P sway on firm surface as risk for future conversion to falling
  • UPDRS factors that were most important were rising from chair, rapid alternating movements and leg agility
