Abstract
Background
Unspecific low back pain causes burden in patients and tremendous costs for the health care systems worldwide. Although guidelines recommend multidisciplinary treatment focusing patients’ empowerment unnecessary surgery or pharmaceutical strategies still prevails. Mobile health applications have been shown promising tools to provide guideline-oriented treatment opportunities to a broad range of patients. 
Objective: So far, medical apps were investigated in randomized-controlled trials or by retrospective data analyses. Yet, to our best knowledge, apps were not evaluated when integrated in a treatment algorithm. The present poster aims to present an interim analysis of the Rise-uP project (Germany) which includes a multidisciplinary mobile back pain app (Kaia App), providing physical exercise, mindfulness and education via smartphone, as main intervention in a GP centered treatment algorithm for lower back pain patients.
Methods: Pain ratings as well as measures of functional ability, psychopathology (anxiety, depression, stress) and wellbeing (mental/physical) at the beginning of the treatment and in a 3- and 6- months follow-up were compared between 108 patients who got access to the Kaia app (Rise-uP group) and 37 control patients who were provided regular treatment (control group).
Results: We found a substantially stronger pain reduction in the Rise-uP group compared to the control group after 3 months (Rise-uP: M=-2.43 (SD=2.38) vs. CG: M=-1.20 (SD=2.67) and after 6 months (Rise-uP: M=-2.57 (SD=2.43) vs. CG: M=-1.24 (SD=3.1) measured on a 11-points numeric rating scale. Compared to the control group, Rise-uP patients also reported stronger increases in functional ability and wellbeing as well as stronger reductions of depression, anxiety and stress at both measure points (3 and 6 months follow-up).
Discussion: Although we present only preliminary results, our data provide further indication that mobile health application may be a promising tool to increase quality of treatment of unspecific back pain especially in a setting with a professional involved. More studies which larger samples have to be conducted to further explore especially the relationship between app adherence and symptom improvement.
