Results
The present study investigated whether the OLP+TAU treatment was effective for Japanese patients with CLBP under the assumption of equal efficacy as in the previous reports. Our results revealed that OLP+TAU showed no significant superior benefit in comparison with TAU alone after 3- and 12-week interventions for Japanese patients with CLBP although significant improvements in functional disability were obtained in both groups at week 12.
