Purpose: This study aimed to investigate the effects of the crocodile breathing exercise on the muscle activity of the erector spinae muscle in patients with low back pain.
Methods: The study subjects included 36 patients with low back pain. The patients were divided equally into the experimental group (EG) and the control group (CG). The EG performed the crocodile breathing exercise, and the CG performed a chest expansion breathing exercise. The intervention was conducted for 10 minutes each day for a total of eight weeks. Measurements of muscle activity were conducted using an MP150 system. An electrode was attached 2 cm to the side of the spinous process at the L4-L5 level. The muscle activity value used was %MVIC, and the statistical significance was 0.05. The paired t-test was the statistical method used to determine the pre- and post-average value of each breathing exercise, while the independent t-test was used to assess the delta value of muscle activity in the pre-post test.
Results: Inspiration muscle activity showed a significant increase in both the EG and the CG, while expiration muscle activity decreased significantly in both groups. The delta value of muscle activity showed a significant difference in inspiration (p<0.05), but for expiration, there was no significant difference in muscle activity (p>0.05).
Conclusion: This study suggests that crocodile breathing is a good method for improving muscle activity in patients with low back pain.
