Evaluation of clinical characteristics and influencing factors in freezing of gait in Parkinson’s disease


  • Freezing of gait (FOG) is prevalent in approximately 50% of individuals with Parkinson’s disease (PD) and is correlated with Hoehn-Yahr (H-Y) stage, postural instability gait disorder (PIGD) subscore, PD-questionnaires 39 (PDQ-39) score, and attention/memory score.

Why this matters

  • The pathophysiology of FOG is well studied but remains unclear, thus studies are needed to elucidate FOG clinical characteristics and influencing factors.

  • This study provides evidence of potential predictors for FOG, which can help improve quality of life and treatment for people with PD through improved research.
