This assessor-blind exploratory randomised controlled trial assigned 50 healthy office workers to a brief video about back pain beliefs and management or an anatomy-video control. The intervention produced a greater improvement in Back-PAQ10 scores (Δ = 6.12, p < 0.001) than the control (Δ = 0.88, p = 0.002), with a significant Group × Time interaction (p < 0.001). However, the groups did not differ in changes to lumbar curvature range of motion or lifting strategy when handling 5 and 15 kg boxes.
Key findings
- Back-PAQ10 scores improved more after the educational video (Δ = 6.12) than after the control video (Δ = 0.88); Group × Time interaction p < 0.001.
- Lumbar curvature range of motion decreased over time (p < 0.001), without a Group × Time interaction (p = 0.604).
- Lifting strategy showed a main effect of Time (p = 0.005), but no Group × Time interaction (p = 0.935).
Why it matters
The findings suggest that a brief educational video can shift back pain beliefs without producing a corresponding change in observed lifting behaviour or spinal motion. This distinction is relevant when evaluating educational interventions: changes in beliefs alone may not indicate changes in movement, and both cognitive and behavioural outcomes may need assessment.
What to keep in mind
The trial involved healthy office workers and measured outcomes immediately after the intervention, limiting conclusions about other populations and persistence of effects.
