A Study of Postural Changes After Breast Reduction

Abstract

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 1year 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. This journal requires that authors assign a level of evidence to each article.
