Abstract

Purpose: The purpose of this study was to compare the pathway of COP and plantar foot pressure and to determine the correlation between plantar regions during the ascending and descending of a ramp. Methods: Fifteen healthy adults who had no musculoskeletal problems participated in our study. They were asked to walk on a level surface and on an ascending and descending ramp in their bare feet. Pathway of COP and plantar foot pressures were recorded using the Matscan system (Tekscan, Boston, USA). For pressure measurements, the plantar foot surface was divided into seven regions: two toe regions, three forefoot regions, a midfoot region, and a heel region. To determine whether there was a statistically significant difference between pathway of COP and plantar foot pressures during walking, we used repeated measuremes ANOVA. Results: In comparison to results for a level walking, pathway of COP while ascending a ramp had a tendency to be shifted medially in the forefoot and became longer till the big toe. Pathway of COP while descending a ramp also was shifted medially, but ended in the forefoot. Plantar foot pressure of the second and third metatarsal head and the fourth and fifth metatarsal heads was significantly decreased while descending the ramp. Conclusion: These results indicated that plantar foot pressure is changed while ascending and descending a ramp and demonstrated that ramp walking can affect the structure and function of the foot. Therefore, gait environment is associated with significant changes in foot characteristics, which contribute to altered plantar loading patterns during gait.
