The various forms of low back pain occur very frequently in the population. Eighty-five percent of the German population experiences it at least once in a lifetime [1]. This leads to high socio-economic importance. The costs caused by non-specific low back pain amounted to 3.6 billion euros in 2008. Chronic low back pain and the resulting loss of work performance play a decisive role in this [2]. The average costs per patient and year in Germany are 1322€ [3]. Furthermore, affected patients have high levels of suffering, and are afraid to lose participation in meaningful activities [4]. The German guideline for the management of nonspecific low back pain recommends treatment approaches which involve the promotion of activity to patients [5]. There is evidence available showing the efficacy of treatments based on mobile applications [6]–[9]. Nonetheless, the range of available apps in the stores is hardly regulated and therefore the quality may vary a lot [10]. Systematic reviews on the availability of mobile applications for the treatment of low back pain have been made [11]–[13]. However, not for Germany or the German speaking area. The aim of this assessment is therefore to create an overview of the availability and quality of such applications. This should help clinicians to advise their patients with nonspecific low back pain. [1] C. O.
