OK, something different this Friday.
We admit computer models can only approximate human gait, and here is a perfect example. Watch the video a time or 2 and come back and read on….
Really….Did you watch it? Maybe you really should…
What do we see?
- A prime example of heel rocker but what is missing? How about midfoot pronation, a requisite for normal gait and one of the 4 shock absorbing mechanisms (pronation, ankle dorsiflexion, knee flexion and hip flexion)
- dip of the opposite hip with initial contact and loading response. looks like the computer model had built in gluteus medius weakness!
- what about that lack of anterior and posterior rock of the ilia?
- they do show g max activation (posterior view) during propulsion…nice!
- where are the abs initiating hip flexion?
- how about that forward head posture?
- we think there should be exaggerated torso rotation (contralateral to the side of strike) with no arms
So what does this prove?
This is a great attempt at simulating human gait, but gait being so complex and ….well….human, it is difficult to approximate with a computer modeling program.
We are the geeks of gait…The Gait Guys…Ivo and Shawn
