Abstract

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.
