Implementation of an app-based neuromuscular training programme to prevent ankle sprains: a process evaluation using the RE-AIM Framework.

BACKGROUND/AIM: The contemporary electronic media is regarded as a practical tool in the dissemination of preventive measures and interventions. For this purpose an App (free of charge) was developed including an efficacious programme for the prevention of ankle sprain recurrences. This study evaluated the implementation effectiveness of this 'Versterk je Enkel' App.

METHODS: The App was evaluated within its practical context using the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) Framework. The launch of the App was accompanied by a press release, website banners, as well as online and offline advertisements. Data for the evaluation of the App were objectively registered through Google analytics. Data were obtained in February 2013 based on 25,781 users resulting in follow-ups of 18 months (iOS version) and 15 months (Android version), respectively. Users questionnaires provided a qualitative view of the objectively assessed measures (n=82) to gain insight into the demographics of users, reasons to download, user experience and how the information was used.

RESULTS: The App reached only 2.6% of the projected target population. User ratings for the App's relevancy, clarity, usefulness, appeal, information and reliability were high. App usage indicates that compliance with the embedded programme was low.

CONCLUSIONS: Although the App was well received by the users, targeted efforts are required to ensure proper uptake and usage of the App by the target population. This also holds true for eHealth and mHealth efforts aimed at athlete care and injury prevention in general.
