Effect of peak plantar presure on plantar corn size

Abstract

Background: Corn and callus are one of the most common problems faced by dermatologists in dermatology clinic. Repeated local irritation to plantar skin results in the thickening of traumatized skin. Corn and callus are often overlooked, and this becomes longstanding problem causing pain when walking and standing up. There is no study explore the correlation between plantar pressure and size of corn.

Objectives: To explore the correlation between peak plantar pressure and size of corn

Materials and methods: 30 participants with plantar corn were recruited in this study. Their plantar corns were measured in millimetre using a dermoscope. Each participant was asked to walk at their normal speed along RSscan platform in order to measure their plantar pressure. After that Teckscan insole plantar pressure system was installed into each shoe. The participants were asked to walk again at their normal pace. Female participants will be asked to bring their high heels with them on the appointment date. Spearman rank correlation was used to analyze whether there was a correlation between magnitude of peak plantar pressure and size of corn.

Results: There was no correlation between magnitude of peak plantar pressure and size of corn (P-value = 0.56). There was a statistically significant correlation between duration and size of corn (P value = 0.006).

Conclusions: These findings demonstrated that the longer the onset of corn, the larger the corn can become. Plantar corn should be treated as soon as possible in order to prevent long term problems.
