Overview

Randomized trial demonstrates improved postural control in chronic ankle instability via cerebellar stimulation, suggesting potential therapeutic benefits.

Key Points

  • To determine if cerebellar-targeted tDCS can enhance postural control in individuals with chronic ankle instability.
  • Randomized, sham-controlled laboratory study involving 22 participants with chronic ankle instability.
  • Participants received either active or sham cerebellar transcranial direct current stimulation for 20 minutes.
  • Pre- and post-intervention assessments included laboratory-based center-of-pressure sway and Balance Error Scoring System.
  • Functional magnetic resonance imaging assessed cerebellar activity and coherence.
  • The tDCS group showed a significant reduction in mediolateral center-of-pressure length (p = 0.020).
  • No significant changes were seen in other center-of-pressure sway or BESS outcomes between groups.
  • A strong correlation was observed between reduced mediolateral CoP length and improved coherence in the superior lobe of the cerebellum (r = -0.709, p = 0.018).
