Video analysis of sagittal posture in female workers with neck and low back pain.

PURPOSE: In this study, we aimed to determine the relationship between spinal posture and pain in female workers with pain complaints through posture analysis using video recordings, with the goal of establishing a foundation for corrective exercise programs.

METHODS

The subjects of the study, female workers at Company H's call center, were divided into non-pain (n = 17), neck-shoulder pain (n = 17), and low back pain (n = 16) groups. The differences between groups and the relationship between angles were analyzed by measuring seven body angles related to posture, which were recorded via video of each participant in both sitting and standing positions.

RESULTS

Significant differences were observed between the neck-shoulder pain and non-pain groups in the neck slope angle (sitting and standing), upper cervical angle (sitting), and thoracic spine angle (sitting and standing). Moreover, there were significant differences between the low back pain and non-pain groups in the neck slope and lumbar spine angles in the sitting position.

CONCLUSION

The neck slope angle is an important indicator of the relationship between spinal posture and pain. These findings suggest that corrective exercises targeting forward head posture may help alleviate both neck-shoulder and low back pain.
