Post Lumbar Disc Surgery:
(Ostelo, 2004)
- MDC = 5.4 (4.2-8.0) scale points (95% CI)
Chronic Low Back Pain: (Dutch version)
(Brouwer et al, 2004; n = 30, mean age=40 (8.1); The duration of pain was between 5-10 years; questionnaire was filled out before beginning therapy and at two weeks follow-up)
Outpatients with low back pain diagnosed with a musculoskeletal origin:
(Stratford et al, 1996)
- MDC = 5 points at 95% CI for scores located in the central portion of the scale. (4 RMQ points are required to detect improvement in patients with initial scores of 4-11 RMQ points and in patients with scores greater than 16 points.)
Outpatients with low back pain diagnosed with a musculoskeletal origin:
(Stratford et al, 1996)
- The Journal of the American Physical Therapy Association found that the MDC for the two groups study found that 8.6 or 9.5 point was needed based on the reliability estimates for these groups.
Chronic and Acute Low Back Pain: (Italian version)
(Monticone et al, 2012; n = 179; mean age=47.7 (12.3); patients had a median duration of pain of 6 months; questionnaires were administered at the beginning and end of eight weeks of rehabilitation.)
Participants classified as Unchanged (Davidson et al, 2002)
- "Unchanged" (n = 47) MDC (95% CI) = 8.6 (6.7–10.6)
- "About the same" (n = 16) MDC (95% CI) = 9.5 (6.3–13)
