Chronic Ankle Instability
Conditions
Interventions
Group A:Participants received anodal transcranial direct current stimulation (a-tDCS) combined with Integrated Neuromuscular Training (INMT). During the intervention, cortical anodal stimulation was a
B Group:Participants received Integrated Neuromuscular Training (INMT) only. No brain stimulation was applied
the intervention consisted solely of structured neuromuscular training to enhance ankle function and motor control.
C Group:Participants received anodal transcranial direct current stimulation (a-tDCS) only. Cortical anodal stimulation was delivered during the intervention period without any concurrent neuromuscula
