Comparative analysis of spinal flexibility in patients with and without lumbar disc herniation

Lumbar disc herniation (LDH) is a common spinal disorder associated with significant pain and disability. Spinal flexibility plays a crucial role in maintaining spinal health and may influence the development and progression of LDH. However, the relationship between spinal flexibility and LDH remains unclear. This study aimed to investigate the association between spinal flexibility and LDH through a comparative analysis of flexion, extension, and lateral bending in patients with and without LDH. A cross-sectional study was conducted involving 60 participants, including 30 patients with clinically and radiologically confirmed LDH and 30 control participants without LDH. Spinal flexibility was assessed using digital inclinometers and goniometers to measure flexion, extension, and lateral bending. Demographic and clinical data were also collected. Statistical analysis was performed using independent t-tests to compare flexibility measurements between groups. Patients with LDH demonstrated significantly reduced spinal flexibility compared to the control group. The LDH group exhibited lower degrees of flexion, extension, and lateral bending in comparison. These differences were statistically significant (p < 0.05) for all measures. This study provides evidence of a significant association between reduced spinal flexibility and lumbar disc herniation. Maintaining and improving spinal flexibility may be crucial in preventing and managing LDH. Targeted interventions aimed at enhancing flexibility, such as stretching exercises and physical therapy, should be considered as part of comprehensive strategies for LDH management.
