Key result
Weight loss of approximately 11.6% significantly decreased static and dynamic plantar pressures across multiple foot areas and resulted in a posterior displacement of the center of pressure.
Why the study?
Obesity is a major public health problem, and this study aimed to evaluate the redistribution of static and dynamic plantar pressures and antero-posterior center of pressure following body weight reduction.
Does body weight loss improve baropodometric parameters (plantar pressures and center of pressure) in overweight subjects?

p-value: p=<0.05
Weight loss in overweight subjects positively affects static and dynamic plantar pressures and induces a posterior displacement of the center of pressure, indicating improved postural balance.
Abstract Background One of the major public health problems of the 21 st century is obesity. Baropodometry is commonly used to determine specific loads on the plantar surface of the foot and the comportment of the body center of pressure (CoP). To evaluate the redistribution of the baropodometric parameters: static and dynamic plantar pressures and antero – posterior CoP, by decreasing body weight. Methods A sample of 43 subjects (24 male, 19 female) participated in the study. A hypocaloric diet was designed with the aim to reduce their body weight. The baropodometric exam was performed in two occasions: weight 1 – Session 1 and weight 2 – Session 2, when they had lost between 12 and 18 kg. The foot was divided in 9 areas: heel, midfoot, 5 metatarsal heads (MTHs), Hallux, 2-5 toes. The Footwork® pressure platform was used to carry out the evaluation. Results Subjects reduce an 11.59% their mean weight. Foot pressure decrease was statistically significant between the first and second measurements (p < 0.05). For the static on the Hallux, 2 nd MTH, 3 rd MTH, 5 th MTH and heel, while for the dynamic the pressure decreases on the whole study areas except on the 2 nd and 5 th toes. For the CoP, a notable posterior displacement was observed. There were no gender differences.Conclusion We can conclude that weight loss affected positively to both plantar pressures and CoP, since statistically significant changes were observed in the baropodometric parameters between the two times studied.

Lanuza-Cerzócimo et al. (2020) conducted a cohort in Overweight and Obesity (n=43). Weight loss intervention (hypocaloric diet and exercise) vs. Baseline (before weight loss) was evaluated on Static and dynamic plantar pressures and antero-posterior Center of Pressure (CoP) (p=<0.05). Weight loss of approximately 11.6% significantly decreased static and dynamic plantar pressures across multiple foot areas and resulted in a posterior displacement of the center of pressure.
