BackgroundIn Germany, exercise therapy represents the most commonly prescribed physiotherapy service for non-specific, chronic low back pain (NSCLBP). So far, little is known about current practice patterns of German physiotherapists in delivering this intervention. Thus, the aim of this study was to investigate the appropriateness of exercise therapy delivered to NSCLBP patients in German physiotherapy care and to identify practitioner-related drivers of appropriate exercise delivery.MethodsWe used a vignette-based, exploratory, cross-sectional, online-survey study design (76-items; data collection between May and July 2023). Eligible participants were required to hold a professional degree in physiotherapy and were required to be practicing in Germany. Access links to anonymous online surveys were spread via established German physiotherapy networks, educational platforms, social media, e-mail lists, and snowball sampling. Appropriateness of exercise therapy was calculated by an equally weighted total score (400 points) including scales on shared-decision-making, exercise dose selection, pain knowledge and self-management promotion. “Appropriate exercise delivery” was determined by a relative total score achievement of > 80%. “Partly appropriate exercise delivery” was determined by a relative total score achievement of 50–79%, and “inappropriate exercise delivery” by a score achievement of < 50%. Practitioner-related drivers of exercise appropriateness were calculated by bivariate and multiple linear regression analyses.Results11.9% (N = 35) of 298 physiotherapists’ exercise delivery was considered “appropriate”, 83.3% (N = 245) was “partly appropriate”, and 4.8% (N = 14) was “inappropriate”. In the final multiple regression model, most robust parameters positively influencing appropriate delivery of exercise therapy were increased scientific literacy (B = 10.540; 95% CI [0.837; 20.243]), increased average clinical assessment time (B = 0.461; 95% CI [0.134; 0.789]), increased self-perceived treatment competence (B = 7.180; 95% CI [3.058; 11.302], and short work experience (B = − 0.520; 95% CI [-0.959; − 0.081]).ConclusionAppropriate exercise delivery in NSCLBP management was achieved by only 11.9% of respondents. However, the vast majority of 95.2% of respondents was classified to deliver exercise therapy partly appropriate. Long work experience seemed to negatively affect appropriate exercise delivery. Positive influences were attributed to scientific literacy, the average clinical assessment time per patient as well as the perceived treatment competence in NSCLBP management.RegistrationOpen science framework: https://doi.org/10.17605/OSF.IO/S76MF.
