Freezing of gait in Parkinson’s disease: A survey of prevalence and contributing factors


  • Prevalence of freezing of gait (FOG) in people with Parkinson’s disease (PD) is correlated with longer disease duration, advanced disease stage, as well as higher scores on the non-motor symptom assessment scale (NMSS).

Why this matters

  • This study indicates that FOG prevalence is impacted by not only motor features, but also non-motor features and activities of daily living, which should all be considered for the proper management of FOG.
