- Abstract
Introduction: Lateral ankle sprains (LAS) are the most common type of sports injury, and the single-leg drop landing (SDL) is used to assess the risk of injury. Individuals at higher risk for LAS display elevated maximum vertical ground reaction force (GRF), reduced mediolateral GRF displacement upon landing, and elevated horizontal GRF displacement in late landing phase. Improving these factors may improve injury prevention.1,2 Ankle flossing improves ankle function and sports performance; however, evidence regarding its effect on SDL or LAS prevention is currently insufficient. Objectives: We examined the effects of one-month ankle flossing on SDL in recreational athletes. Study design: Pilot randomized controlled trial. Methods: Twenty-one healthy recreational athletes who met baseline eligibility criteria were randomly allocated into a flossing group (FLOSS), which performed active exercises (ankle plantar dorsiflexion exercises and plyometric jumps) with a floss band wrapped around the ankle, and a control group (CON), which performed the same exercises without the floss band. Both groups performed the assigned interventions before every sports activity for approximately one month. Assessment measures were GRF index (maximum force, root mean square, horizontal force, and time to stabilization) during SDL, which was measured before and after the intervention. Mixed-model two-way analysis of variance was conducted for each item, using group and time as factors. Results: An interaction between groups and times was observed for maximum vertical force during landing (p=0.02), with a 5.2%BW decrease (p=0.48) and a 21.3%BW increase (p<0.01) in FLOSS and CON groups, respectively. The horizontal force from 0.4 to 2.4 s after landing decreased by 0.29%BW in the FLOSS group (p=0.02) and increased by 0.02% BW in the CON group (p=0.84). Conclusions: One month of ankle flossing prevented a vertical GRF increase and improved horizontal stability during SDL
