Transcranial Direct Current Stimulation Combined With Balance Training for Chronic Ankle Instability: A Double-Blind, Pilot Randomized Controlled Trial
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).
