The purpose of this study was to determine if there are functional performance deficits in athletes with functional ankle instability(FAI) in 3-types of hop test & Y-balance test, including side hop test, figure-of-8 hop test, and square hop test. Fourteen male (functional ankle instability) and thirteen male (Non functional ankle instability group) were selected based on the questionnaire (Chunberland Ankle Instability Tools: CAIT). Thereafter, functional performance were measured in this study. The results indicated that functional performance ability by 3-types of hop test of ankle joint in the FAI group was lower than the NFAI group. There was a significant difference in igure-of-8 test between the FAI and the NFAI. In addition, functional performance ability by Y-balance test in the FAI group was lower compared to the NFAI group. There was no significant difference between the FAI and the NFAI. Consequently, this study suggests that the side hop test & the figure-of-8 hop test might be an excellent tool to assess functional ankle instability. Further study is needed to determine if the Y-balance test is an appropriate tool to assess functional ankle instability.
