IASI Webinar: Leg Torsion Assessment as a Guide to Realistic Goals for Each Structural Integration Client

Presenter: Jeffrey Burch

Webinar Description:

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. 

Learning Objectives:

  • A straightforward method to make an accurate assessment of the developmental torsion in each long bone of the legs. 
  • Use this information about the unique torsion of each femur and tibia to guide the work with that client.
  • Provide movement education to each client, based on their unique structure, about how to stand and move with ease and comfort.

Featured Speaker:

Jeffrey Burch received a BA in biology from the University of Oregon in 1975, after which he trained at The Dr. Ida Rolf Institute® in Boulder, Colorado, receiving his Certification as a Rolfer in 1977. He has been in continuous practice since then.

Jeffrey Burch received his Rolfing Advanced Certification in 1990, after which he again began studying at the University of Oregon where he received a second BA in Psychology in 1993 and a Master of Science in Counseling in 1995. His Masters thesis “Alexithymia and Dissociation” explores topics related to psychosomatic conditions.

In 1998, Jeffrey began intensively studying CranioSacral Therapy through the Upledger Institute, Cranial Manipulation with French Osteopath Alain Gehin, and Visceral Manipulation with Jean-Pierre Barral and his associates. Jeffrey completed the apprenticeship to teach visceral manipulation. He independently offers specialized courses in visceral manipulation with the permission of Jean Pierre Barral.  He also offers foundational courses in assessment methods and treatment methods.

Starting in 2010, he began to develop groundbreaking new methods to assess and release adhesions and contractures in joint capsules, bursas, and tendon sheaths. In 2015 he began to teach these methods to other therapists.
