I hacked a Mickey Mouse toy in order to measure sagittal flexion and extension in the hip joint. I did this by finding the leads to the motor that controls the hips, and powering it externally with a battery. Oh yeah, I had to skin him first too. By doing this I was able to isolate only the motions Mickey made when walking.
I then used an angle guide for a saw to measure flexion and extension
Both flexion and extension terminated at 18 degrees, making the full range of motion 36 degrees. I believe this is comparable to a human gait, which, if I'm reading this chart correctly, is 40 degrees (30 to -10).
