A study of postural changes after abdominal rectus plication abdominoplasty

Factors such as body masses and humour are known to influence human posture. Abdominoplasty, which causes a sudden change in body masses, significantly improves body image and self-esteem. The aim of this study was to assess postural changes after abdominoplasty by studding the position and orientation through space of the body and the centre of pressure. METHODS: Patients affected by excess abdominal skin and/or significant abdominal muscular anterior wall laxity due to undergo an abdominoplasty were enrolled. Posture was evaluated both before and for 1 year after surgery by quantifying the centres of mass, using the Fastrak™ system, and the centre of pressure, using stabilometry. The Wilcoxon signed-rank sum test was used to compare changes. RESULTS: Forty-six patients were enrolled. A retro-positioning of the pelvis with a compensatory advancement of the head and shoulders, confirmed by the baropodometric analysis, was evident in the early post-operative period. The biomechanical system subsequently stabilized, achieving a state of equilibrium 1 year after surgery. CONCLUSIONS: We believe that the change in posture following abdominoplasty is a consequence of both surgery (changes in body masses) and psychological factors that influence posture. Indeed, redundant abdominal skin and abdominal muscular anterior wall weakness are often associated with kyphosis since patients try to hide what they consider to be a source of embarrassment. The discovery of a new body image eliminates dissatisfaction, reduces anxiety and increases self-esteem, which provide psychological and physical benefits that improve the quality of life.
