Main Researcher for Effects of Lumbar Stabilization Exercise on Transversus Abdominis Muscle Activation Capacity and Function in Chronic Low Back Pain Patients

Purpose: The purpose of this study is to investigate the effects of lumbar stabilization exercises on pain intensity, transversus abdominis muscle (TrA) activation capacity, functional disability, and TrA thickness in patients with chronic low back pain (CLBP). Subjects: The subjects of this study were 30 CLBP patients. Methods: The experimental group performed diverse lumbar stabilization exercises in different postures, and the control group conducted an ordinary trunk muscle strengthening exercise. Results: There were significant differences in pain intensity, TrA activation capacity, functional disability, and TrA thickness between before and after the intervention in both groups. Significant differences between the two groups were shown in the pain intensity, TrA activation capacity, and functional disability after the intervention. However, there were no significant differences between the two groups in TrA thickness. Conclusion: Lumbar stabilization exercises in different postures could reduce pain, functional disability, and increase TrA activation capacity and thickness in CLBP patients.
