A systematic search and assessment of the quality and characterisation of free mobile applications targeting knee pain.

Abstract

This study aimed to assess free mobile apps targeting knee pain and to characterise and critically analyse the interventions described in them. A systematic search was performed in the Apple store, Play Store and Microsoft Store. A total of 26 applications met the inclusion criteria and were evaluated using the Mobile Apps Rating Scale (MARS), and for their content against guidelines on knee pain intervention. The mean MARS total score was 3.3 (±0.5) and the mean subjective quality score was 2.1 (±0.9) out of a maximum of 5 points each. Most apps combined different types of exercises 88% and included both exercise and pain education (62%). These results suggest a need to improve the quality of these apps aiming to create more engagement and improve app usage. Additionally, as health apps maybe useful in pain management and be an alternative to complement rehabilitation, the involvement of health professionals is important during the development process of the apps including evidence-based content and progression recommendations.
