The Influence of Weight Loss in Postural Control in Women Undergoing Sleeve Gastrectomy

Abstract

Background: Bariatric surgery is the most effective procedure for obesity management, with a greater body weight loss and the remission of several diseases. The aim of this study was to analyze the relationships between the anthropometric profile and postural control outcomes in a group of obese adult women, and the effect of bariatric surgery on postural control. Methods: eighty-eight women candidates for bariatric surgery were recruited. Static balance was measured with the ARGO stabilometric platform under two conditions: open eyes (OE) and closed eyes (CE). Results: Multiple linear regression indicated BMI as the first predictor for postural control in all parameters, except for APO in open eyes, predicted mainly by height. Changes in body weight and BMI showed no statistically significant correlations with modification of postural control parameters (OE), while they appeared to exert an influence under closed eyes conditions. Conclusions: Before surgery, obese patients with a higher BMI showed a better postural control. After surgery, the sway path and antero-posterior oscillation improved under open eyes conditions, while the magnitude of weight loss was negatively correlated with differences in postural control.

From surgery to functional capacity: muscle strength modifications in women post sleeve gastrectomy

“…Obesity is classified by the World Health Organization by Body Mass Index (BMI), usually associated with other body parameters such as waist circumference, waisthip ratio, and waist-height ratio used as an indicator of abdominal obesity and cardiovascular risk [1,2]. Severe obesity is characterized by excessive accumulation of fat [3] generating an inflammatory state correlated with general health worsening, quality of life and higher risk to develop hypertension, dyslipidemia, diabetes, metabolic syndrome [4], and musculoskeletal impairment affecting mobility and gait capacity [5][6][7].…”
