Everything OLD… Is NEW! WHY?

Then how come everything NEW is OLD? “The utility of the prone leg extension as a clinical and functional test is questionable due to the normal variability and our current inability to determine what is normal and what is dysfunctional. ” Proper Firing Patterns?

Biotensegrity • Muscles, Tendon, Fascia provide a continuous pull. • Bones provide a discontinuous push. • Bones “float”, & never physically touch each other with the exception of disease processes. • All of the spines 186 joints are involved with every movement of the body. • Support of the spine (& body) originates from above as well as below. • Muscles which are silent or low EMG activity are an important part of the whole control pattern

The Fascia System Connects the Dots! § "Ligaments do not exist, because they are so emeshed with connective tissue that the pictures we see in anatomy texts are science fiction“- Van Der Wal ‘ 09. §Fascia is able to contract in a smooth muscle like manner and thereby influence musculoskeletal mechanics- Liepsch et al 2006 § 30% of muscle force is transmitted through the connective structures in parallel (Lieber '97, Huijing '99). § "The virtually instantaneous reconfiguration (of fascia) suggests the effect of manual therapy can be immediate & significant. It is a serious challenge to the classical representation and modeling of biomechanical systems. “- Gracovetsky ’ 09 §

“There is no one universal exercise for trunk control that would account for the specific needs of all activities. Is it possible to train the trunk control to specific activity? Yes, and it is simple – just train in that activity and don’t worry about the trunk. The beauty of it all is that no matter what activity is carried out the trunk muscles are always specifically exercised. ” –E. Lederman “The myth of core stability” (publish pending, Journal of Bodywork & Movment Therapies 2009)
