Understanding a change score is indispensable for interpretation of results from clinical studies. One way of determining the relevance of change scores is through the use of transition questions that assesses patients' retrospective perception of treatment effect. Unfortunately, results from studies using transition questions are difficult to compare since wording of questions and definitions of important improvements vary between studies. ⋯ Results demonstrated small variations in ROC(auc) across the external criteria for all outcome measures. 7% more patients were classified as improved in the group receiving the 15-point TQ compared to the 7-point TQ (stringent standard). SRMs were higher for the retrospective TQs in primary sector patients compared to the serial measures with no difference between TQ1 and TQ2. On the basis of our findings we have outlined a proposal for a standardised use of transition questions.

Purpose of this study is to examine the relationship between the magnetic resonance imaging (MRI) findings, pain scores, and opiates use in patients with lumbar spinal stenosis (LSS) undergoing lumbar epidural steroid (LES) injections by retrospective review of 719 patients' electronic medical records. ⋯ The improvement in VAS pain scores after LES injections correlated well with the changes in the SPI except in those patients classified on MRI as severe LSS and more than 3 lumbar levels affected. That patient group is unlikely to benefit from LES injections.

Prospective cohort study with 10-year follow-up. ⋯ Radiologic results, patient satisfaction, and mean scores for quality of life and back function were excellent after CD instrumentation for AIS, but a considerable number of patients had treatment for back problems.

[Correlation of back pain and magnetic resonance imaging of the lumbar spine in elite horse vaulters].
A connection between morphologic lesions of the spine and specific sport disciplines incorporating torsional and hyperextension forces has been found. Although vaulting incorporates a significant amount of figures known from gymnastics, little is known about the influence of this sport on the lower back. The aim of our study was to assess to what extent vaulters suffer from back pain and whether these symptoms correlate to findings in magnetic resonance imaging (MRI) of the lumbar spine. ⋯ Vaulters, compared to riders of other disciplines, seem to suffer from recurrent back pain to a greater extent. Despite the fact that the lumbar spine is confronted with repetitive torsional and hyperextension forces, vaulters do not show undue early degenerative changes or marked lesions of the lumbar spine. Recurrent back pain in the vaulter is most likely due to functional problems. It seems unlikely that is based on manifest morphologic changes of the lower back.
