Objective:

The increase in the incidence and prevalence of orthopedic foot may be related to changes in the plantar pressure distribution disorders in overweight and obese individuals. Therefore, the purpose of the present study was to investigate the plantar pressure distribution in overweight and obese individuals.

Methods:

The study included a total of 94 individuals between the ages of 19 and 62 years. Individuals were divided to two groups according to body mass index (BMI) as normal weight (BMI<25 kg/m2) and overweight or obese (BMI≥25 kg/m2). Static plantar pressure distribution and force measurement during static standing in individuals were assessed using MatScan System (Tekscan, Inc., South Boston, Massachusetts, USA).

Results:

Overweight and obese individuals had more contact area (p<0.001), force-time integral (p=0.002) and midfoot maximum force (p<0.001) than normal weight individulas. Weight of individuals had a fair correlation with peak pressure (r=0.23, p=0.026), mean pressure (r=0.24, p=0.018), midfoot maximum force (r=0.35, p=0.001), metatars maximum force (r=0.36, p<0.001) and pressure-time integral (r=0.30, p=0.003) and a moderate correlation with heel maximum force (r=0.47, p<0.001), and a strong correlation with contact area (r=0.79, p<0.001) and force-time integral (r=0.66, p<0.001).

Conclusion

Obtained results show that increased loading in foot because of increase in body mass cause a increase in contact area. Increase in midfoot maximum force in obese and overweight individuals suggest that increase in contact area is related to the increase in midfoot contact area because of the decrease in medial longitudinal arch.
