Bariatric surgery and exercise: A pilot study on postural stability in obese individuals

Area of Science:

• Kinesiology
• Obesity Research
• Bariatric Surgery

Background:

• Obesity significantly impacts overall health, including balance and postural stability.
• Bariatric surgery is a common intervention for severe obesity, but its effects on postural control require further investigation.
• Postural stability is crucial for preventing falls and maintaining functional independence.

Purpose of the Study:

• To analyze changes in static postural stability after bariatric surgery.
• To evaluate the effect of a structured exercise program on postural stability in individuals who have undergone bariatric surgery.

Main Methods:

• Twenty-two individuals with obesity (BMI 35-55 kg/m²) were assessed.
• Participants were divided into an exercise group (n=10) and a control group (n=12).
• Static postural stability was measured using a pressure plate before and 4 months post-surgery.

Main Results:

• No significant changes in Center of Force (CoF) sway, CoF ranges, or average speed were observed before and after surgery.
• The exercise program did not yield significant improvements in static postural stability.
• Age was negatively correlated with post-surgery improvements in some postural stability parameters.

Conclusions:

• Bariatric surgery alone does not appear to significantly improve static postural stability in individuals with obesity.
• A 3-month exercise intervention did not demonstrate a significant effect on enhancing postural stability post-bariatric surgery.
• Further research is warranted to explore the complex relationship between bariatric surgery, exercise, age, and postural control.
