L-spine coupling
flexion - ilial post rot
extension - ilial ant rot
Pelvis coupling
uni ilial post rot = ilium outflare = ER of acetabulum/hip
Femur coupling
ER femur = ER tibia
Tibia coupling
ER = up glide of talus and foot sup
Fibula coupling
foot sup = cranial anterior glide of fibular head
R LLD (l-spine, pelvis, femur, tibia, fibula, ankle/foot)
R SB, L rot R post torsion R femur add, ER R tibia ER R fibular head cranial and ant R foot sup, talus ER and upward
