Randomized Controlled Trial
Agreement of self-reported items and clinically assessed nerve root involvement (or sciatica) in a primary care setting.
We analysed baseline measures from an RCT involving adults with low back pain (LBP) with or without referred leg pain, to identify self-report items that best identified clinically determined nerve root involvement (sciatica). ⋯ In this primary care population seeking treatment for LBP with or without leg pain, we found no clear set of self-report items that accurately identified patients with nerve root pain. When accurate case definition is important, clinical assessment should be the method of choice for identifying LBP with possible nerve root involvement.

Randomized Controlled Trial
Is the development of Modic changes associated with clinical symptoms? A 14-month cohort study with MRI.
Modic changes (MCs) have been suggested to be a diagnostic subgroup of low back pain (LBP). However, the clinical implications of MCs remain unclear. For this reason, the aims of this study were to investigate how MCs developed over a 14-month period and if changes in the size and/or the pathological type of MCs were associated with changes in clinical symptoms in a cohort of patients with persistent LBP and MCs. ⋯ The presence of MCs type I at both baseline and follow-up is associated with a poor outcome in patients with persistent LBP and MCs.
