Abstract

|
|
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 groupsconducted 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 strengthand pain control in patients with CLBP.
