The Nordic Back Pain Subpopulation Program: A 1-Year Prospective Multicenter Study of Outcomes of Persistent Low-Back Pain in Chiropractic Patients

The outcome pattern is similar to that found in other clinical studies. Treatment outcome should be measured early with follow-up at 3 rather than at 12 months, because patients will improve or recover quickly but may experience recurring problems. Numbers “cured” appear to be a feasible outcome variable in this type of study population.
