In this case, plantar flexion (equinus) both increases the wheel's radius (good) and CENTERS the wheel axis to be below the center of mass from

forward travel as from A toward B. A little knee flexion helps sometimes.

[Knee flexion can be looked at as an angle H-K-A. Or, as a line H-A which having magnitude AND direction is both a body and an environment relative VECTOR. [later, but the engineers are now tisking. Tisk tisk.]. Hip – Ankle Relative Position [ HARP] is a room relative vector. Much better than the knee angle although they measure the same think. Knee ankles are for the bozos who want to sound knowledgeable. Vectors are for the knowledgeable who want to make a difference.] Wait. No.. no nooooooooo. Wait wait. Plantar flexion? Really? Equinus, is a good thing? No. It is ' a ' thing. If looking for a work-around, it is there, as an option . But people – patients – don't do THAT! Do they? (Later. The answer = yes). Inman was not aware of this, though. So, at this point, no, not while discussing his determinants. That list should be amended. But, we have more of his original 6 determinants to discuss.
