Abstract Summary
The purpose of this study was to further understand the role of plantar-surface sensation in modulating muscle activity. The additional of texture to orthotics served as a mechanism to manipulate mechanoreceptors in the sole of foot. The study divided the plantar foot surface into 5 distinct areas. 55 healthy adults performed level walking trials while muscle activity was recorded in eight lower leg muscles. Results indicated that the addition of texture to different areas under the foot sole successfully modulated lower limb muscular output. This research has large scale implications to foot orthoses professionals, and furthers our understanding of the neuromotor paradigm supporting foot orthoses use.
