Numerous factors such as the equilibrium of body masses and psychological status influence human posture. Breast reduction, on the one hand, produces a sudden change in this equilibrium, and on the other hand, it can modify the psychological status, significantly improving body image and self-esteem. This study aimed to assess postural changes after breast reduction by studying the position and orientation in space of the body and center of pressure.
The study enrolled 52 patients with breast hypertrophy scheduled to undergo breast reduction. Posture was evaluated before surgery and during the first year after surgery by quantifying the centers of mass using the Fastrak system and the center of pressure using stabilometry. The Wilcoxon signed-rank sum test was used to detect any changes.
Retropositioning of the upper part of the body, confirmed by baropodometric analysis, was observed in the early postoperative period. The biomechanical system subsequently stabilized, reaching equilibrium 1 year after surgery.
The authors believe that postural changes after breast reduction are due to changes in body mass as well as to the effects of physical and psychological factors on posture. Indeed, breast hypertrophy often is associated with kyphosis as patients try to hide what they consider to be a source of embarrassment. A new breast eliminates previous dissatisfaction with body image, reduces anxiety, and increases self-esteem. Improvements in body image and reduced weight in the anterior part of the body help to correct this postural disorder.

许多因素，如身体质量的平衡和心理状态，都会影响人体姿势。乳房缩小术一方面会导致这种平衡的突然变化，另一方面会改变心理状态，显著改善身体形象和自尊心。本研究旨在通过研究身体和重心在空间中的位置和方向来评估乳房缩小术后的姿势变化。
该研究纳入了 52 名接受乳房缩小术的乳房肥大患者。通过使用 Fastrak 系统量化质量中心和使用稳定性测量法量化压力中心，在术前和术后 1 年内评估姿势。使用 Wilcoxon 符号秩和检验检测任何变化。
早期术后观察到身体上部的后移，通过 baropodometric 分析得到证实。生物力学系统随后稳定下来，术后 1 年达到平衡。
作者认为乳房缩小术后的姿势变化是由于体重变化以及身体和心理因素对姿势的影响所致。事实上，乳房肥大通常与脊柱后凸有关，因为患者试图隐藏他们认为是尴尬之源的东西。新的乳房消除了以前对身体形象的不满，减轻了焦虑，提高了自尊心。身体形象的改善和身体前半部分的体重减轻有助于纠正这种姿势障碍。
