AbstractFollowing abdominal surgery, many patients assume a bending or stooping posture to protect the surgical wound. Such postural changes are known to induce side effects, but the improvement and persistence of these effects are unknown. Therefore, the purpose of this study was to clarify the nature of postural changes in patients undergoing abdominal surgery. In this prospective cohort study, we enrolled 25 patients who underwent abdominal surgery from February 2019 to January 2020. Measurements were obtained during the preoperative, pre-discharge, and first outpatient stages. The sacral tilt, lumbar lordotic, thoracic kyphosis, and overall tilt angles were measured in the static standing position in a private room. Wound pain was measured using a Visual Analogue Scale. Repeated measures analysis of variance was applied to compare spine measurements for each measurement period, followed by the Bonferroni method for each level. Pearson's product-moment correlation coefficient was performed to examine the relationship between wound pain and spinal column angle. The lumbar kyphosis angle was lower before discharge (-7.2 ± 7.4°) compared to preoperatively (-11.1 ± 7.5°) (95% CI 0.76, 7.08; P < .01, η2 = 0.21). Regarding the overall tilt angle, the anterior tilt angle increased before discharge (3.4 ± 3.9°) compared to preoperatively (1.1 ± 4.1°) (95% CI 0.86, 3.78; P < .01, η2 = 0.33). No statistically significant correlation with pain was observed. Compared to the preoperative period, the patients had an anterior tilt, mainly due to lumbar spine changes, prior to discharge from the hospital. Changes in spinal alignment were not associated with wound pain.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
