Summary

The purpose of this research study is to examine the efficacy of non-invasive brain stimulation in addition to balance exercise for chronic ankle instability (CAI), a condition that develops following an initial ankle sprain, usually because of loose or unstable ankle joints.

Conditions

• Ankle Injuries and Disorders

Interventions

Type	Name	Description
DEVICE	Anodal tDCS	An anodal surface electrode will be attached to the contralateral motor cortex (M1) of the CAI-involved side and the reference electrode will be placed on the ipsilateral side of the supraorbital ridge. Anodal tDCS will deliver a low electrical current stimulation at 2 milliamps (mA). Participants will undergo 3 sessions per week for a total of 12 sessions and each session will last approximately 20 minutes.
DEVICE	Sham tDCS	An anodal surface electrode will be attached to the contralateral motor cortex (M1) of the CAI-involved side and the reference electrode will be placed on the ipsilateral side of the supraorbital ridge. Sham tDCS will deliver a low electrical current stimulation at 2 mA and will be turned off 30 seconds following the application. Participants will undergo 3 sessions per week for a total of 12 sessions and each session will last approximately 20 minutes.
