The knee and ankle are both hinge joints, however, during growth and development, the axes of rotation of the two joints are only transiently parallel to each other. At birth, the axis of the ankle joint is internally rotated about 15 degrees with respect to the knee joint. During the growth and development, the tibia gradually twists along its length so that usually at about age 5-6 the two axes are parallel. In adulthood, any amount between 5 and 18 degrees of external rotation of the axis of the lake joint with respect to the axis of the knee joint is considered normal. Beyond this "normal" amount of tibial torsion, common range variants are from no change where the infantile 15 degrees of internal rotation is retained in adulthood, to 25 degrees of external rotation. The two legs in one person never have the same amount of tibial torsion. The femur undergoes a similar torsion along its length during growth and development with that substantial differences between people. Again, the two femurs in one person are rarely the same. Since the hip is not a hinge joint, femoral torsion is calibrated a different way. This webinar teaches a practical method to assess the torsion of each femur and each tibia to develop a realistic picture of these aspects of the native architecture of each person's legs. Knowing this feature of the uniqueness of each client's bony architecture provides a guide to assisting each client to find ease in their body.
