Purpose: This study aimed to confirm the effects of visual feedback based eccentric pulley training (EPT) on muscle strength, pressure pain threshold, and chronic low back pain (CLBP). Methods: All subjects were randomly divided into 3 groups; 18 subjects in the visual feedback-based EPT (VF-EPT) group, 18 subjects in the EPT group and 18 subjects in the eccentric training (ET) group. All groups conducted 30 minutes of training per session, and the training was performed 3 times a week during 4 weeks. For muscle strength evaluation, all subjects were assessed for the muscle strength of trunk rotation, squat & trunk rotation, single-leg deadlift, seated lat pull down motion. For pain evaluation, Pressure Pain Threshold (PPT) was measured. Results: Results showed statistically significant changes in muscle strength in all groups (p<0.05), however, no significant difference was observed between groups. PPT was statistically significant in all groups (p<0.05) and differences were observed between groups (p<0.05). Conclusion: The results suggested that visual feedback training can be effective in improving muscle strength and pain control in patients with CLBP.
