This study aimed to explore the influence of fibular repositioning taping (FRT) on pain and function in individuals with lateral chronic ankle instability (CAI). This was a randomized clinical experiment in which 66 lateral CAI volunteers between the ages of 18 and 50 were selected randomly to one of three equivalent groups (I, II, and III). Group (I) received FRT, group (II) received FRT and exercises while group (III) received exercises only. Pain was evaluated using the Arabic version of the Numeric Pain Rating Scale, and function was evaluated using the Arabic version of the Foot and Ankle Ability Measure. within groups, when compared to pre-treatment, all three groups had significant improvements in pain and function after treatment among groups, Pain, and function post-mean values showed statistically significant differences, with group (II) outperformed groups (I) and (III), as well as group (III), outperformed group (I) FRT may be an effective treatment in CAI, yet exercise has shown better results than FRT in enhancing pain and function.
