BACKGROUND: To both prevent and accelerate recovery and return-to-play from ankle sprains, clinicians frequently employ the use of external prophylactic support (EPS), such as taping and bracing, to provide mechanical support to the ankle joint. While common practice clinically, research has been inconclusive in demonstrating the effectiveness of EPS in restricting accessory motion (laxity) throughout activity, as well as its efficacy in restricting laxity in patients with complaints of ankle instability, and patients with a history of ankle sprain. The purpose of this study was to investigate the effectiveness of EPS type (None, Tape, Brace) on ankle laxity before and after exercise in subjects with varying degrees of previous ankle injury. METHODS: Ankles from 24 participants (age, 20.6 ± 1.6 years; height, 173.6 ± 8.3 cm; mass, 72.8 ± 12.2 kg) were placed into one of three groups: healthy control (CON), potential coper (COP), and functionally unstable (UNS). Ankle laxity was assessed using an ankle arthrometer at 4 points in time; prior to EPS application, immediately following EPS application, following a 20-minute functional exercise protocol with EPS, and following removal of EPS. Peak ankle anterior displacement (ANT), inversion rotation (INV), and eversion rotation (EVR) were compared between groups and across conditions using a three-way ANOVA. RESULTS: Taping and bracing each decreased laxity from pre-application to pre-exercise and post-exercise. Tape provided greater restriction post-exercise in inversion and eversion rotation. Additionally, the UNS group demonstrated significantly greater anterior displacement post-exercise following removal of the brace compared to other groups. CONCLUSION: Compared to pre-application and post-removal, EPS significantly decreased ankle laxity before and after physical activity, with taping providing better restriction in inversion and eversion rotation throughout exercise. CLINICAL RELEVANCE: Following EPS removal, bracing revealed a greater increase in post-exercise laxity in subjects with ankle instability, suggesting tape may be more beneficial for controlling laxity in these patients. |
