Chronic ankle instability
Conditions
Interventions
No-compression condition:No floss band compression was applied. Participants performed standardized movement tasks for 2 minutes, including ankle dorsiflexion–plantarflexion, inversion–eversion, and s
40% compression condition:A floss band was applied at 40% of the individual surface occlusion pressure. Under compression, participants performed standardized movement tasks for 2 minutes, including a
60% compression condition:A floss band was applied at 40% of the individual surface occlusion pressure. Under compression, participants performed standardized movement tasks for 2 minutes, including a
80% compression condition:A floss band was applied at 80% of the individual surface occlusion pressure. Under compression, participants performed standardized movement tasks for 2 minutes, including a
