Inclusion criteria
Inclusion criteria: Concussion group: The study recruited undergraduate and graduate students from Beijing Sport University. Inclusion criteria included: (1) a history of diagnosed concussion or neurological changes within 24 hours after head impact, loss of consciousness for less than 30 minutes, Glasgow Coma Scale score between 13 and 15; (2) injury occurred between 1-15 years ago; (3) self-reported experience of postural control disorders; (4) age between 18 and 35. Healthy control group: The study recruited healthy volunteers who were matched with the concussion group in terms of age and gender without significant differences.
Exclusion criteria
Exclusion criteria: Concussion history group: (1) Currently taking any medication that may affect balance or cortical excitability of the brain; (2) Any self-reported lower limb injury or hospitalization in the past six months; (3) History of vestibular or ocular dysfunction; (4) Previously suffered from moderate to severe traumatic brain injury, neurological disease, cardiovascular disease, or musculoskeletal system disease affecting posture control ability; (5) Presence of any contraindications for tDCS such as internal metal implants, any discontinuity in skull conductivity (i.e. unhealed scalp drill holes or artificially created metal or plastic skull windows). Healthy control group needs to follow the same exclusion criteria and have no history of head trauma and serious neurological diseases.
