A comparison of planatar pressure variables during three differntrunning patterns in pronated feet individuals with and withoutlow back pain

Individuals with pronated feet suffer from many biomechanical dysfunctions during running. The purpose of this study was to compare the peak plantar pressure in ten areas of the foot, ground
reaction force, center of pressure and loading rate during three different running patterns between healthy subjects and pronated feet individuals with and without LBP.

This semi-experimental and laboratory study was performed as a comparative research between three groups including healthy subjects (n=10), pronated feet individuals with (n=10) and without (n=10) low back pain. Plantar pressure variables were evaluated in 10 areas of the foot. Statistical analysis was performed using MANOVA test at a significance level of 0.05.

The loading rate was significantly different between the three groups during running. There was a significant difference in loading rate in the mid-foot running pattern between the pronated feet individuals with and without low back pain. The loading rate in the pronated individuals with low back pain was higher in the mid-foot running pattern than in the rear-foot running pattern.

The forefoot running pattern compared with other running patterns is more suitable for pronated feet individuals with low back pain. However, further study is warranted.
