Ground reaction forces and plantar pressure distribution during occasional loaded gait
چکیده انگلیسی

This study compared the ground reaction forces (GRF) and plantar pressures between unloaded and occasional loaded gait. The GRF and plantar pressures of 60 participants were recorded during unloaded gait and occasional loaded gait (wearing a backpack that raised their body mass index to 30); this load criterion was adopted because is considered potentially harmful in permanent loaded gait (obese people). The results indicate an overall increase (absolute values) of GRF and plantar pressures during occasional loaded gait (p < 0.05); also, higher normalized (by total weight) values in the medial midfoot and toes, and lower values in the lateral rearfoot region were observed. During loaded gait the magnitude of the vertical GRF (impact and thrust maximum) decreased and the shear forces increased more than did the proportion of the load (normalized values). These data suggest a different pattern of GRF and plantar pressure distribution during occasional loaded compared to unloaded gait.


► There is an overall increase on plantar pressure and GRF during loaded gait.
► Plantar pressure distribution pattern is different between unloaded and loaded gait.
► In backpackers the midfoot and toes pressure increased more than the load proportion.
► There seems to be a protective behavior during backpacker's gait.
