Responsiveness of the Falls Efficacy Scale-International and Activities-Specific Balance Confidence Scale in Parkinson's disease.

Key Points

• This research aims to establish meaningful metrics for interpreting changes in balance confidence among individuals with Parkinson's disease.
• Conducted a study on individuals with Parkinson's disease (PwPD) using the Falls Efficacy Scale-International (FES-I) and Activities-Specific Balance Confidence (ABC) scale.
• Estimated the minimum clinically important difference (MCID), the minimal detectable change (MDC), and the standard change benchmarks (SCB) for both scales.
• Analyzed the responsiveness of FES-I and ABC to evaluate balance and fear-of-falling interventions.
• Established robust MCID, MDC, and SCB estimates for FES-I and ABC in PwPD.
• Provided clinically meaningful benchmarks for interpreting changes in balance confidence related to interventions.
