Overview

Randomized trial evaluates balance control impact of tDCS during balance training in chronic ankle instability, suggesting no added benefits.

Key Points

  • This pilot study aims to evaluate the effects of transcranial direct current stimulation (tDCS) on balance and ankle function in individuals with chronic ankle instability (CAI).
  • Nineteen individuals with CAI were randomized to active or sham tDCS.
  • Participants received 20 minutes of anodal tDCS during balance training, 3 times a week for 4 weeks.
  • Outcomes included static postural control and corticospinal excitability assessed at baseline, during, and after the intervention.
  • Small group differences were observed at weeks 2 and 4 for most measures in the active-tDCS group compared with sham.
  • Center of pressure area under the eyes-closed condition showed a moderate effect (d = -0.62).
  • Fibularis longus corticospinal excitability demonstrated a large effect (d = -0.88).
