Comparison of Preform Orthoses
Study by La Trobe University (AUS)
Realignment of the foot is one of the aims of foot orthoses when treating signs and symptoms associated with biomechanical dysfunction of the foot and lower limb. We have previously tested a number of prefabricated foot orthoses in their ability to change the alignment of the foot by measuring changes in the frontal plane position of the calcaneus. We also tested the Interpod™ range using a similar methodology. The mean number of degrees that the calcaneus changed position for all subjects for each of the devices is listed below:
Rubber arch cookie
6 degree high density EVA wedge
Control Tech Soft (moderate)
Control Tech Soft (high arch)
Control Tech Flex (low arch)
Control Tech Flex (moderate)
Control Tech Flex (high arch)
Slim Tech soft (low arch)
MEAN (+SD) CHANGE IN FRONTAL PLANE POSTION OF THE CALCANEUS
It can be concluded from this that the Interpod™ range is at least as effective as re-aligning the foot as the Orthopro™ Prothotic™ and the 6 degree heel wedge.
Interpod™ is more effective in realigning the foot than Vasyli™ and Formthotic.
