What is the effectiveness of external ankle support in the prevention of inversion ankle injury in recreational and elite sportsmen and women? A systematic review with a meta-analysis (including a numbers needed to treat analysis).
This review will consider any studies that include sports men and women of any age group, participating in both recreational and elite sports. Participants with or without ankle injuries will be included. Studies reporting on athletes with other musculoskeletal injuries other than ankle injuries or post-surgical cases will be excluded from this review.
This review will consider studies that have evaluated the effectiveness of external ankle supports, such as taping and bracing and their ability to prevent ankle injury and re injury rates.
This review will consider studies that compare the intervention of external ankle support to interventions that have no ankle support or no intervention, as well as studies which may utilise modified footwear, training programmes such as proprioceptive exercises, ankle strengthening exercises and ankle injury awareness programmes.
This review will consider studies that include both primary and secondary outcomes. The primary outcomes will focus on the prevalence and incidence of ankle injury and re-injury rates, as well as the severity of ankle injuries. In order to calculate the correct NNT analysis, the studies must report the numbers of injuries sustained within the treatment group compared to a population that did not have external support. Secondary outcomes include pain, range of motion, performance and function. All studies will be included if they have described clearly the injury classification (mild, moderate, severe).
