Propulsion: the sequence reverses toward ER and supination. Orientation = pelvis turning as a unit. Relative motion = individual segments rotating within the chain. ER / IR = external / internal rotation. *Hip joint rotation is the pelvis-on-femur description in the course chart; it may read opposite the femur's rotation in space. Course-model study aid.
