Results: Improvement was found in all outcomes measured in bothgroups (p<0.05) with the exception of depression. JMLPL was better than JMregarding pain at MUMO, MUMO only at 2 weeks, anxiety at 4 and 8 weeks andsomatization only at 8 weeks. Conclusion: Improvements were found inreduction of pain at MUMO, MUMO and in the indexes of psychosocial aspectsin both groups.
