Athletes with chronic ankle instability especially in jump and landing sports (basketball, volleyball, and football) who fully returned to sport. Chronic ankle instability Ankle sprain Athletes Rehabilitation
Conditions
Interventions
We will use the 4-weeks progression dynamic balance-training program created by McKeon et al (2008) for individuals with CAI. The exercises consist of single-limb hops to stabilization and hop to stab
s ability to maintain a single-limb stance while landing from a hop under various balance and unstable conditions. Before progression to the next level of difficulty in each of the 4 components, an er

Inclusion criteria
Inclusion criteria: Basketball, volleyball, and football players in university level, age 18-25 years old and BMI in range of 18-25 kg/m2 who have history of CAI will be included in this study. The classification for CAI will be by ankle injury history questionnaire and the 30-point Cumberland ankle instability tool (CAIT). The CAI participants had a history of significant lateral ankle sprain at dominant side (at least once) more than 1 year of initial sprain (41), feeling of giving away in ankle in the 6 months before study at least 1 time (42), and a CAIT score less than and equal to 25 (43). Moreover, CAI individuals will demonstrate negative anterior drawer test and talar tilt test of ankle joint for excluding mechanical instability of ankle.
Exclusion criteria
Exclusion criteria: 1. History of musculoskeletal problem such as joint pain or muscle pain of lower extremities within 3 months before study. 2. History of serious injury or operation of lower extremities such as ACL reconstruction, fracture of femur, or ankle fracture. 3. History of low back pain in 6 months before the study by receiving medication or physical therapy. 4. History of taking medication or agent related to change of muscle properties such as muscle relaxant within 24 hours before testing. 5. Participants who can't pass the safety screening for TMS machine.
