Abstract/OtherAbstract:
CONTEXT. Altered foot dynamics due to the malalignment of the foot may change plantar pressure properties which result in various kinds of overuse injuries. OBJECTIVE. The purpose of this study was to assess the effect of foot characteristics on plantar pressure related measures such as maximum pressure, maximum pressure time, and pressure time integral underneath the medial aspect of the foot during running. DESIGN. Cross-sectional design. SETTING. Laboratory. PATIENTS OR OTHER PARTICIPANTS. Eight males and 17 females were recruited for this study. MAIN OUTCOME MEASURES. Static non-weight bearing rearfoot and forefoot alignment, and navicular drop were measured. Plantar pressure data were collected while subjects jogged at 2.6m/s on a treadmill. Maximum pressure, time to maximum pressure, and pressure time integral of the medial side of the foot were extracted for data analysis. Multiple regression analysis was used to examine the effect of arch height and rearfoot and forefoot alignment on maximum pressure and pressure time integral in the medial side of the foot. RESULTS. In the medial rearfoot and midfoot regions, only rearfoot alignment had a significant effect on the variance of maximum pressure and pressure time integral. There were no significant difference effects in the medial forefoot region. CONCLUSION. Rearfoot alignment was found to be a significant predictor of the maximum plantar pressure and pressure time integral in the medial rearfoot and midfoot regions. This indicates that the control of rearfoot alignment may aid in the decrease of plantar pressure on the medial region of the foot which may potentially prevent injuries associated with excessive rearfoot eversion.
