Inclusion criteria
Inclusion criteria: Individuals with chronic ankle instability (CAI): (1) Aged 18-30 years, with regular exercise habits and right-handedness; (2) With functional ankle instability; (3) Had at least one severe right ankle sprain in the past 12 months, which caused pain, swelling, etc., and could not bear weight without pain for at least 1 day after the injury; (4) In the past 6 months, the injured ankle joint had at least 2 "soft legs" and/or repeated sprains, and felt ankle instability, and the most recent injury occurred 3 months before this test; (5) Cumberland Ankle Instability Tool score = 24 points, indicating impaired ankle function; (6) Functional Ankle Instability Identification Score = 11 points. Ankle sprain (Coper) individuals: (1) Aged 18-30 years old, with regular exercise habits and right-handedness; (2) At least one severe right ankle sprain occurred in the past 12 months, causing pain, swelling, etc., and unable to bear weight without pain for at least 1 day after the injury; (3) In the past 6 months, the injured ankle joint has experienced less than or equal to one "soft leg" phenomenon, and has no history of sprain; (4) Cumberland Ankle Instability Tool score = 28 points, indicating that the ankle joint function is good and there is no instability; (5) Functional Ankle Instability Identification Score = 10 points. Healthy individual: (1) Aged 18-30 years old, with regular exercise habits and right-handedness; (2) No history of ankle sprain; (3) Cumberland Ankle Instability Tool score = 30 points, indicating that the ankle joint function is good and there is no instability; (4) Functional Ankle Instability Identification Score = 0 points.
Exclusion criteria
Exclusion criteria: Chronic ankle instability (CAI), ankle sprain (Coper) and healthy individual: (1) Any history of surgery on the musculoskeletal structures of the lower limbs (i.e. bones, joint structures and nerves); (2) Acute injuries to the musculoskeletal structures of other lower limb joints in the past 3 months, affecting the integrity and function of the joints (i.e. sprains, fractures), resulting in at least 1 day of interruption of physical activity; (3) Any neurological disease, such as spinal cord, vestibular, brain damage, or any disease that affects sensation or balance function; (4) Neurological problems that affect vision, etc.; (5) A history of severe cognitive impairment.
