Freezing of gait (FOG) is a common and debilitat ing symptom in individuals with Parkinson’s disease (PD), often leading to falls. Its incidence and severity vary significantly, even among people with identical disease profiles. This variation in the presentation of FOG highlights the existence of numerous underlying processes and pathologic variables. Furthermore, the pharmaceutical response varies significantly among patients, emphasising the importance of differentiating the FOG subtypes for optimised therapeutic strategies. However, due to the lack of specialised motor and cognitive testing, current FOG assessment methods are unable to categorise subtypes. To address this essential gap, we developed the Understanding FOG (UnFOG) scale. This new technique is designed for clinical and research use, providing a complete method for documenting the clinical manifestations of FOG while incorporating cognitive tests. UnFOG has the potential to revolutionise our understanding of FOG subtypes by combining these discoveries, paving the path for more personalised and successful treatment techniques. This study has the potential to improve the lives of Parkinson’s disease sufferers while also expanding our understanding of this complex disease.
