Anthropometry and Plantar Pressure Distribution During Gait in Obese Subjects: A Novel Approach

Traditionally, research on plantar pressure in overweight/obese populations has focused on dividing the plantar surface into two or three regions, considering factors such as body mass index (BMI), age, and gender. This study took a different approach, incorporating various anthropometric measurements representing body shape, including arm, leg, and shoulder lengths, as well as thigh, chest, waist, hip, and ankle circumferences. Utilizing retrospective data from obese and healthy male subjects, the study yielded results revealing robust correlations with Euclidean measurements, circumferential measurements, and circumferential ratios. Interestingly, while no significant correlations were found between peak plantar pressure magnitude and location with BMI, significant correlations were seen with lower and upper arm length, shoulder length, waist circumference, and thigh circumference. Incorporating ratios that combined multiple measurements showed promise, with correlation coefficients exceeding 0.75. These findings suggest that a complete plantar pressure analysis should not solely rely on BMI but rather include a thorough examination of body shape presented by subject anthropometry. The results also highlighted the feasibility of developing an index for plantar pressure prediction based on anthropometric data. Further research and expanded datasets are crucial for refining and validating these findings.
