Background <p>Changes in human posture directly impact the structures of various body parts, often leading to musculoskeletal disorders. While identifying suitable treatments for pain associated with long-term postural abnormalities is important, preventing such conditions is demonstrably a superior solution. Spiral stabilization, known for its practical application, has proven effective in treating low back pain. However, its efficacy in correcting human posture warrants further validation.</p> Methods <p>A total of 71 participants with abnormal body posture, with a mean age of 33.68 ± 6.78 years, were included in this research. The participants underwent spiral stabilization practice for one hour daily for four days. The posture-related angles and deviations from the anterior and lateral views were calculated by the Exbody musculoskeletal analysis system.</p> Results <p>There are statistically significant improvements in most posture-related angles and deviations after the intervention of the spiral stabilization technique compared to before the intervention (<i>P</i> &lt; 0.05).</p> Conclusion <p>The findings of this study suggest that the spiral stabilization technique is a potential intervention for improving human posture. It may become an effective fitness exercise that is widely adopted in daily life to prevent postural abnormalities.</p> Trial registration <p>Registration date is July 10, 2021.
