The data analyst will also be blinded to group identity during the primary statistical analysis by using coded group labels. Thus, blinding will be maintained for the outcome assessor and data analyst, while participants will be blinded to the study hypothesis and the expected direction of the effects. N/A chronic ankle instability. Intervention 1: Intervention group: The mental-fatigue groups will perform a 30-minute incongruent visual Stroop task. Intervention 2: Control group: The control group will watch a non-emotional documentary for 30-minute. Yes - There is a plan to make this available What will be shared: Most data is shareable. When: Access period begins after results are published. To whom: the data will be available to physiotherapists. Conditions: researchers and physiotherapists Where to obtain: Applicants can contact the following email for more information: nahid_pt8287@yahoo.com How to obtain: after authentication and if approved by the people participating in the study, the individual can receive the information.
