NCT02022124

Brief Summary

Patients will be randomized to receive open-label (honestly described placebo) immediately at baseline or be eligible to receive the open-label treatment three weeks after the baseline measurements. Therefore all patients will be eligible to receive open-label placebo treatment for their chronic low back pain during the course of the study.
