Abstract
The results of this study suggest that the thickness of a metatarsal support is a determinant factor in regulating plantar loading. Surprisingly, the longitudinal axis location of a metatarsal support does not appear to be as important as clinically presumed since the data showed that the force decrease was similar for all positions from 5 to 25 mm. Thus, the orthotic induced effect of a metatarsal support seems to have a sizable interaction range that has not previously been reported. We speculate that the metatarsal support's fulcrum and lift effect can be sustained at a more proximal position due to the foot's rigidity as a lever and the manner in which a metatarsal support interacts with the plantar aponeurosis.
