Randomized Controlled Trial
Correlation of measures of pain, function, and overall response: results pooled from two identical studies of etoricoxib in chronic low back pain.
Assessment of correlation of measures of low back pain (LBP) using data pooled from 2 identical studies. ⋯ In this study, the RMDQ, LBPI VAS, and PGART showed a high degree of correlation in measuring response to therapy in LBP, suggesting clinicians may be able to simplify assessments.

A prospective cohort study. ⋯ The significant association between medium level back extension endurance and increased LBP intensity supports the finding of other studies that particularly back extension endurance is an important physical fitness component in preventing LBP and that the subcomponents of physical fitness are related in different ways to LBP.
