Introduction & Objective: Today ,a lot of work forces are lost and this problem costs too much for the patient and the governments. Exercise therapy is one of the most important plans for these patients. The aim of this study was to compare the effectiveness of coordination training , Endurance training and combinations of them on CLBP.

Materials & Methods : We performed a randomized trial on 60 patients with CLBP who were referred to Shiraz Masjedorrasool physiotherapy clinic. Patients were divided into three groups and all groups were treated by the same routine physical therapy management. The first, second and third group received Endurance exercises, Coordination exercises and   combinations of them respectively. Pain and disability were compared among three groups.

Results : All three methods were effective in pain relief(p=0.00) but the 3^rd method was more effective than the 1^st and 2^nd methods(p=0.001 and p=0.003 respectively). Also ,the 1^st and 2^nd methods were not significantly different from each other in treatment of CLBP(p=0.718). All three methods were effective in reducing patients disability (p=0.00). But the 3^rd method was more effective than the 1^st and 2^nd methods (p=0.001 and p=0.006 respectively). Also , the 1^st and 2^nd methods were not significantly different from each other in reducing disability(p=0.529).

Conclusion : Endurance training besides coordination training is more effective than each one alone.
