The Nordic Back Pain Subpopulation Program: Validation and Improvement of a Predictive Model for Treatment Outcome in Patients With Low Back Pain Receiving Chiropractic Treatment

In this study, patients with LBP who also had leg pain and LBP occurring sufficiently frequently or having lasted sufficiently long to add up to at least 30 days in the past year, and who did not report definite general improvement by the second treatment were not good candidates for short-term recovery. It is suggested that patients who fit the criteria of potential nonresponders should be carefully monitored to allow a selective approach of care.
