Clarification of reporting of outcome measures and protocol deviations in report of a randomized clinical trial

To the Editor We commend the authors for their randomized clinical trial that investigated the effects of pain neuroscience education combined with cognition-targeted motor control training, compared with best-evidence physiotherapy, on chronic spinal pain.1 The authors found that pain neuroscience education combined with cognition-targeted motor control training is more effective than current best-evidence physiotherapy for improving pain. To ensure that clinicians select interventions that will have a clinically meaningful effect, we ask the authors to clarify (1) the reporting and interpretation of outcome measures and (2) the reporting of protocol deviations.
