Background: Thoracic kyphosis is a condition characterized by an excessive curvature of the thoracic spine, often leading to decreased trunk range of motion and various health complications. Objectives: This study aimed to investigate the effects of a rolling corrector on trunk range of motion (ROM) and thoracic kyphosis angle in individuals with thoracic kyphosis. Design: A randomized controlled trial. Methods: Thirty participants with a thoracic kyphosis angle of 40 degrees or more were randomly assigned to either the rolling corrector group (RCG) or the control group (CG). The RCG used the rolling corrector for 30 minutes per session, five times a week for two weeks, while the CG received no intervention. Trunk ROM and thoracic kyphosis angle were measured before and after the intervention. Results: The RCG showed significant improvements in trunk flexion, extension, lateral flexion, and rotation ROM, as well as in the thoracic kyphosis angle, in within-group comparisons (P<.05). The CG did not exhibit significant changes in any of these variables (P<.05). Significant differences between the RCG and CG were observed in trunk ROM and thoracic kyphosis angle (P<.05). Conclusion: The rolling corrector was effective in improving trunk ROM and reducing the thoracic kyphosis angle in individuals with thoracic kyphosis. These findings suggest that the rolling corrector may be a beneficial intervention for managing thoracic kyphosis.

Background: Technological developments have led to the creation of a mechanical device capable of providing a representative massage as a passive treatment. The use of mechanical massage offers the distinct advantage of being user-friendly and available for use at any given time. Objectives: To investigated present the outcomes of utilizing a massage bed on the range of motion (ROM) and pressure pain threshold (PPT) in patients diagnosed with chronic low back pain. Design: ABA design of a single case study. Methods: To measure the ROM of the subject's trunk flexion, extension, lateral flexion, and rotation, a tape measure and goniometer were utilized. Furthermore, PPT was measured using an electronic pressure pain meter. Baseline A and Baseline A’ periods were conducted for 5 consecutive days without intervention. Following the baseline periods, a massage bed intervention was administered for 1 hour daily for a total of 10 days during the Intervention B period. Daily assessments were performed, and the Intervention B period was conducted after the intervention. Results: The ROM effect was confirmed in trunk lateral flexion and rotation, while the PPT was effective in both L1, right L2, left L4, and left L5. Conclusion: The results of this study confirmed that the use of a massage bed improved the ROM and PPT in patients suffering from chronic back pain. Further randomized controlled trials involving a larger sample size are necessary to validate these findings.
