This 1983 Volvo Award paper by Roland and Morris describes the development and validation of the Roland-Morris Disability Questionnaire (RMDQ). The central question: can a short, patient-completed tool reliably and sensitively measure physical disability from low back pain in primary care? The RMDQ is a 24-item scale derived from the Sickness Impact Profile, completed in approximately five minutes.
Back pain trials in the 1970s repeatedly failed to show treatment effects — not because the treatments were ineffective, but because three-point symptom scales lacked the sensitivity to detect modest real differences between groups.
When you need to measure disability in a back pain patient (for a trial, for treatment monitoring, or for benchmarking severity), use the RMDQ rather than a simple pain score. A score ≥14 at four weeks defines poor outcome and flags the roughly 15% of primary care patients who are not recovering.
Do not rely on physical examination alone to quantify how much back pain is limiting a patient's daily life. This paper showed doctors detected gait abnormality in only 50% of patients who self-reported walking more slowly. Your exam reflects what a patient can do in the office, not what they actually do at home.
The RMDQ and the Oswestry Disability Index are the two dominant back pain outcome tools: the RMDQ is best for tracking short-term changes and milder disability in primary care; the Oswestry is better suited for more severe or chronic disability in surgical and specialty populations.
