Objective: To evaluate the efficacy of a newly developed evidence-based low back pain (LBP) management smartphone application. Design: A double-blinded randomized controlled trial where participants randomly assigned to either an experimental group (EG) or a control group (CG). Setting: Governmental and private institutions. Participants: About 40 office workers, aged 30 to 55 years, had pain due to non-specific LBP > 3 on Visual Analogue Scale, and with pain chronicity > 3 months. Interventions: The EG received full version of the application ‘Relieve my back’ included evidence-based instructions and therapeutic exercises for LBP management, whereas the CG received placebo version included instructions about nutrition. Main measures: Primary outcome measures included pain measured by Visual Analogue Scale (VAS), disability measured by Oswestry Disability Index (ODI), and quality of life measured by Short-Form Health Survey (SF-12). Results: Following six weeks of using the application, compared to CG, the EG group demonstrated significant decrease in pain intensity (−3.45 (2.21) vs −0.11 (1.66), P < 0.001), in ODI score (−11.05 (10.40) vs −0.58 (9.0), P = 0.002), and significant increase in physical component of SF-12 (12.85 (17.20) vs −4.63 (12.04), P = 0.001). Conclusion: ‘Relieve my back’ application might be efficacious in reducing pain and disability and improving the quality of life of office workers with non-specific LBP.

The study showed the main barriers to ICU physical therapy practice in Jordan. There is a need for well-structured strategies to overcome these barriers to help improve the delivery of physical therapy services in Jordan.
