Purpose : This study aimed to investigate the effects of a thoracic flexibility exercise program on pain, heart rate variability (HRV), and depression in patients with chronic low back pain.
Methods : Fifty patients with chronic low back pain participated in this study. Each participant performed a pre-test and post-test. The outcome measures evaluated were a visual analog scale, HRV test results (automatic activity, standard deviation normal to normal [SDNN], low frequency [LF], high frequency [HF], and LF/HF ratio), and the Beck Depression Inventory. Patients underwent conventional physiotherapy for 35 minutes per session. In addition, a thoracic flexibility exercise program (trunk rotation exercise, McKenzie exercise, and supine thoracic extension exercise) were performed 3 times per week for 4 weeks.
Results : After the training period, the visual analog scale results showed a significant decrease in the post-test compared to the pre-test. Automatic activity, SDNN, LF, HF, and LF/HF ratio significantly increased in the post-test compared to the pre-test. The Beck depression inventory results significantly decreased in the post-test compared to the pre-test.
Conclusion : This study demonstrated that a thoracic flexibility exercise program improves a visual analog scale, HRV (automatic activity, SDNN, LF, HF, and LF/HF ratio), and the Beck Depression Inventory in patients with chronic low back pain.
