- Description: Objectives: To describe the association between participants' person-related potential predictor variables and cumulative compliance with interventions for preventing ankle sprains: neuromuscular training, wearing an ankle brace, and a combined training and bracing. Design: Secondary analysis of compliance data from a randomized controlled trial (RCT) comparing measures preventing ankle ligament injuries. Methods: Ordinal regression with a backward selection method was used to obtain a descriptive statistical model linking participants' person-related potential predictor variables with the monthly cumulative compliance measurements for three interventions preventing ankle ligament injuries. Results: Having had a previous ankle injury was significantly associated with a higher compliance with all of the preventive measures trialed. Overall compliance with bracing and the combined intervention was significantly lower than the compliance with NM training. Per group analysis found that participating in a high-risk sport, like soccer, basketball, and volleyball, was significantly associated with a higher compliance with bracing, or a combined bracing and NM training. In contrast, participating in a high-risk sport was significantly associated with a lower per group compliance with NM training. Conclusions: Future studies should include at least registration of previous ankle sprains, sport participation (high- or low-risk), experience in NM training, and hours of sport exposure as possible predictors of compliance with interventions preventing ankle sprains. Practitioners should take into account these variables when prescribing preventive neuromuscular training or bracing. (C) 2015 Sports Medicine Australia. Published by Elsevier Ltd.

- Description: Background: E-health has the potential to facilitate implementation of effective measures to prevent sports injuries. Aim: We evaluated whether an interactive mobile application containing a proven effective exercise programme to prevent recurrent ankle sprains resulted in higher compliance as compared with regular written exercise materials. Methods: 220 athletes participated in this randomised controlled trial with a follow-up of 8 weeks; 110 athletes received a booklet explaining an 8-week neuromuscular training programme; 110 athletes participated in the same programme in an interactive mobile App (Strengthen your ankle). The primary outcome was compliance with the exercise programme. Secondary outcome measure was the incidence density of self-reported recurrent ankle sprains. Results: The mean compliance to the exercise scheme was 73.3% (95% CI 67.7% to 78.1%) in the App group, compared with 76.7% (95% CI 71.9% to 82.3%) in the Booklet group. No significant difference in compliance was found between groups. The incidence densities of self-reported time-loss recurrences were not significantly different between both groups (HR 3.07; 95% CI 0.62 to 15.20). Summary: This study shows that the method of implementing the exercises by using an App or a Booklet does not lead to different compliance rates. New findings: The use of a mobile App or a Booklet lead to similar compliance and injury rates in the short term. Trial registration number: The Netherlands National Trial Register NTR 4027.
