OBJECTIVE: To test the clinical effect of a web-based lower back pain intervention on quality of life and selected lower back pain outcomes. DESIGN: A
prospective single-blinded randomized intervention. SETTING: Occupational
preventive service.
SUBJECTS: One hundred office workers with non-specific
subacute lower back pain. INTERVENTION: The 50 intervention group subjects were
educated daily about sitting correctly and asked to perform exercises shown by
video demonstrations on the university website. The exercise routines included
strengthening, mobility and stretching exercises focused on the postural
stability muscles. The 50 control group subjects only received standard
occupational care. MEASURES: Outcomes were measured by the EuroQol questionnaire
five dimensions three levels, the Oswestry Disability Index, and the StarT Back
Screening Tool questionnaires. At nine months, the intervention group outcomes
were compared to the baseline data and the control group outcomes. RESULTS: For
97% (n = 45) of the experimental group quality of life (clinical utility)
improved significantly; 3.58 times greater than the control group. Oswestry
Disability Index showed an odds ratio (OR) of 5.42 with a 37% (n = 17) change for
the intervention group with respect to the control group. With regard to the
StarT Back Screening Tool, 76% (n = 35) of the intervention group improved their
clinical state (odds ratio = 3.04 with respect to the control group improvement).
Logistic regression analysis revealed positive changes in EuroQol questionnaire,
increasing the likelihood of observing positive changes in StarT Back Screening
Tool (OR = 15.5) and Oswestry Disability Index (OR = 4.5). CONCLUSIONS: The
intervention showed clinical improvements in quality of life and selected lower
back pain outcomes in the experimental group compared to the control group.
