Abstract
This study aimed to analyze the changes in postural stability of individuals with obesity after bariatric surgery, and the effect of three months of regular exercise on the static postural stability. Twenty-two subjects (7 females and 15 males) aged 31 to 68 years (Body mass index 35–55 kg.m-2) completed the study. Participants were divided into two groups: one group participated in an exercise program after the bariatric surgery (n = 10; age 48.9 ± 7.5 years; Body mass index 42 ± 5.6 kg.m-2) while the second group did not exercise at all after bariatric surgery (n = 12; age 44.7 ± 13.6 years, Body mass index 42.6 ± 6.0 kg.m-2). Static postural stability was measured using a Tekscan MobileMat pressure plate before and 4 months after the bariatric surgery. The exercise program included exercising three times a week including: one hour of strengthening, one hour of aerobic group exercise and at least one session of individual exercise at home. There were no significant differences in Center of force sway, Center of force ranges and average speed before and 4 months after bariatric surgery. Also, no effect of exercise was found. Post-pre differences of some parameters were negatively related to age (r from—0.46 to—0.72). Further studies are needed to explore this topic in depth.
Highlights
Obesity has become a major global health concern that is gaining prominence in health care, and in the economy, where one of the frequent topics are the economic consequences of obesity [1]
There were no significant differences noted in the postural stability (PS) parameters, as many evidenced a tendency to worsen
This is the first study attempting to investigate the effectiveness of a cardio/strength exercise program on static postural stability in bariatric surgery (BS) patients using static platform posturography
Summary
Obesity has become a major global health concern that is gaining prominence in health care, and in the economy, where one of the frequent topics are the economic consequences of obesity (e.g. lower wages, a lower probability of employment, and higher medical care costs) [1]. Growing evidence indicates that being overweight negatively affects functional aspects such as standing up [2], walking [2], balance and stability [3]. Postural stability is often described as the ability to respond to changes in internal and external forces and the ability to ensure an upright posture to prevent falls [4, 5]. Many studies report worse static and dynamic postural stability in individuals with obesity compared to individuals with normal body mass index (BMI) values [6,7,8,9,10,11]. There are studies that oppose the above outcome [12, 13].
