Overview

Randomized trial investigates cortical activation and motor performance related to fear of falling in older women, suggesting implications for neurorehabilitation.

Key Points

  • This study aims to explore how fear of falling affects brain activation and motor performance in older women.
  • Evaluated 55 participants including 40 older adults and 15 younger controls.
  • Measured motor reaction time and recorded cortical activity using EEG.
  • Analyzed data with ANOVA and Pearson's correlation, considering α ≤ 0.05.
  • Significant differences in cortical arousal (p = 0.014) and emotional valence (p = 0.004) were found.
  • Higher fear of falling levels were linked to reduced prefrontal symmetry and slower reaction times.
  • Strong negative correlations were observed between emotional valence and reaction times (r > -0.9).
