Background: Core stability training has been widely advocated for management of patients with chronic low back pain to minimize attacks and as a preventive measure; however specific effects of this type of training are not fully investigated.

Purpose: The purpose of this study was to investigate trunk muscles’ response to core stability exercises in patients with chronic low back pain.

Materials and Methods: Thirty male patients who had nonspecific chronic low back pain were randomly assigned to either core stability training or dynamic strength training for 8 weeks. Peak torque of trunk flexors and extensors were evaluated using the Biodex Isokinetic System; and endurance time for flexors, extensors, and lateral trunk musculatures were evaluated through McGill’s core endurance tests.

Results: There was a significant increase in trunk muscles’ peak torque and endurance time in core stability exercises group compared with lumbar dynamic strength exercises group post treatment. Both groups showed improvement in trunk flexors and extensors strength; however, core stability group improved endurance time for trunk flexors, extensors, and lateral muscles, dynamic strength group improved endurance time of flexors and extensors but not of the lateral muscles.

Conclusion: Core stability exercises effectively increase trunk muscles’ strength and endurance. The core stabilization exercises are more effective in improving strength and endurance of trunk muscles than the dynamic strengthening exercises in the patients with chronic low back pain.

Key words: Core stability, low back pain, endurance, Trunk muscles.
