C linicians treating patients with Parkinson disease (PD) and balance impairments are frequently faced with the difficult task of helping them overcome fall-related activity avoidance. Beyond the association with falls and impaired balance, fall-related activity avoidance has been identified as a risk factor for exacerbating impairments, thereby contributing to a greater functional decline and worsening disability in those with PD.1 Although several cross-sectional studies have identified an association between fear of falling and a variety of factors in PD, there is a need for prospective longitudinal studies to identify factors that predict fall-related activity avoidance.2,3 This would help clinicians provide more targeted interventions with the goal of preventing fall-related activity avoidance and its associated sequelae. In this issue, Nilsson and colleagues4 begin to address this gap by examining predictive factors of fall-related activity avoidance in 151 people with PD over a 3-year period. A multivariate linear regression analysis was conducted with fall-related activity avoidance as the dependent variable and a number of baseline factors as potential predictors.
