The Change of Plantar Pressure According to the Height of Heel Lifts in Obese and Non-Obese and Non-Obese Adults

The purpose of this study was to assess the peak plantar pressure distribution under foot areas according to the height of heel lifts in obese adults and non-obese adults during walking. Thirty-one participants volunteered for this experiment. The average body mass index (BMI) value of the fourteen subjects in the obese group was (from 25.1 to 29.3 ), and of seventeen subjects in the non-obese group was (from 18.7 to 22.7 ). The subject ambulated while walking in the sneakers, walking with 2 cm heel lifts, and walking with 4 cm heel lifts in the shoes. We measured the peak plantar pressure under the hallux, 1st, 2nd, 3~4th, and 5th metatarsal head (MTH), mi foot, and heel using F-scan system. The obese group had significantly higher peak plantar pressure under all foot areas than the non-obese group regardless of the height of heel lifts (p
