Comparisons of Plantar Pressure Distributions between the Dominant and Non-dominant Sides of Older Women during Walking

[Purpose] The purpose of this study was to investigate the differences in plantar pressure distributions between the dominant and non dominant sides during walking by older women with a history of falling. [Subjects] Fourteen older women without foot problems participated in this study. [Methods] Plantar pressure distributions between the dominant and non-dominant sides were recorded using the F-scan system (Tekscan Inc, Boston, USA). Measured parameters included peak plantar pressure and surface area contact during the stance phase from heelstrike to toe-off. [Results] Although there were no differences in peak pressure, contact surface area was significantly greater in the first metatarsal (M1) and heel (H) regions of the dominant side compared to the non-dominant side. [Conclusion] Unequal weight distribution indicated by a greater contact surface area may be an indicator of fall risk during walking by older adults with a history of falls.
