Summary

Obesity increases forefoot pressure and foot support area, potentially leading to musculoskeletal issues. Interventions like exercise and surgery may help restore normal gait and reduce joint stress.

Area of Science:

  • Biomechanics
  • Orthopedics
  • Obesity research

Background:

  • Limited research on obesity's impact on foot structure and function.
  • Obesity may affect the musculoskeletal system through altered foot biomechanics.
  • Computerized baropodometric analysis (CPA) assesses foot pressure and gait parameters.

Purpose of the Study:

  • Investigate biomechanical foot dysfunctions in obese individuals using CPA.
  • Compare foot pressure patterns between bariatric, overweight, and normal-weight subjects.
  • Understand the relationship between obesity, foot pressure, and musculoskeletal health.

Main Methods:

  • Recruited 67 subjects (obese, overweight, normal-weight) with varying BMIs.
  • Utilized CPA to measure center of pressure, plantar area, and pressure distribution during quiet standing.

  • Analyzed pressure patterns in different foot regions.

    • Main Results:

    • Obese individuals showed significantly increased forefoot peak pressure.
    • Obese subjects exhibited a larger plantar ground contact area compared to controls.
    • These changes suggest an adaptive response to support increased body weight.

    Conclusions:

    • Obesity leads to excessive forefoot pressure and an enlarged foot support base.
    • While adaptive, these changes can result in maladaptive musculoskeletal consequences.
    • Recommendations include re-education exercises and bariatric surgery for the morbidly obese to improve gait and minimize joint stress.
