How to add a character primitive colliders?

Hi, I am working on a project with Kinect. Basically I have a character which attached the script to achieve move, this works fine. The problem is I need to add basic to different body parts (hand, forearm, leg, etc) to do this, I add collider capsule to arm colliders, I adjust the parameters of height, center and radio, but to move the character at this point the mesh is not deformed well (I guess that is change the center property of the collider).

Anyone know how to solve this? Thank you!
