Table 1.

The desired position was obtained with a free floating foot plate attached to a subject's foot. Actual positions accounted for a limitation in the ALD which prevented the full plantar flexion that most subjects could obtain during passive movement. When this limit was determined with the foot positioning device of the ALD reattached the other two angles were backed off by the same percentage of their maximum and this new position 1 was used to determine positions 2–4. Note that left and right feet had different signs for γ and β.
