Functional ankle instability (FAI) is often observed in athletes with higher ankle sprain risk and repeated ankle sprains will influence athletes’ performance. Therefore, how to prevent ankle sprains is an important issue. Manufacturers indicated that advanced shoes’ technology could provide better protection for preventing sports related injuries. However, whether that statement could assist landing stability, prevent injuries and enhance performance is still unclear. Purpose: The purpose of this study was to compare the landing stability and functional performance in FAI subjects wearing basketball shoes or canvas shoes. Methods: Nineteen healthy women, 10 controls and 9 FAI (age: 21.20 ± 1.55 vs. 21.78 ± 1.72 years; height: 159.45 ± 4.25 vs. 162.33 ± 4.85 cm; weight: 52.60 ± 5.52 vs. 54.44 ± 6.85 kg; BMI: 20.73 ± 2.53 vs. 20.63 ± 2.03 kg/m^2) were recruited. All FAI patients had unilateral instability in the dominant leg and had no acute ankle sprain in the past 3 months. All subjects performed side hop and square hop tests. Data including low limb kinematics, kinetics and electromyography were collected during side hop test. Mixed design and repeated measures two-way ANOVA were used to analyze all parameters. Statistical significance was set at α = .05. Result: (1) There were no significant differences between different groups (FAI vs. health groups) and types of shoes (barefoot vs. wearing shoes) in the ROM of plantar/dorsiflexion during landing phase. Although FAI was not significantly different compared to healthy group in ROM of inversion/eversion during landing phase, but barefoot group was significantly smaller than wearing shoes group. (2) Except for soleus muscle, there was no significant difference in muscle activities between different groups and types of shoes. (3) There was also no significant difference in loading rates between groups and types of shoes. (4) Finally, there was also no significant difference between groups and types of shoes in exercise performance. Conclusion: Our results show that basketball shoes had no effects on decreasing ankle inversion/eversion ROM as compared with canvas shoes and barefoot during side hop test. FAI patients wearing shoes didn’t reduce ROM of ankle inversion/eversion. Therefore, we conclude that wearing basketball shoes might not able to provide enough ankle protection, better cushion and exercise performance than canvas shoes.
