Kinect model controller for unity

I have a basketball player model with joints similar to kinect joints and i want to attach kinect data with my model, i mean i will use kinect data as inputs for my model. I tried a lots of things but i couldn't figure out how i can limit rotations of my model ,when kinect sends inconsisted data , my model's hand for example rotates 360 degrees which it shouldn't be. I used Mathf.clamp but it did not work.(I use Microsoft Kinect SDK). please help me..
