Over the past 10 years there has been a great deal about “Core Stabilization.” However, it seems that it has lost its meaning and turned into more of a catch-all phrase. At ARIS Physical Therapy we believe that the Core does have a specific meaning and that stabilization of the Core is important to achieving higher levels of function. To accomplish “Core Stabilization” one must understand what the Core consists of and why its stability is imperative. We teach concepts like; progression from proximal (near) to distal, stable to unstable, and mobility on stability, etc. Although, Core Stabilization is important it is of no use if the individual is not able to perform correct biomechanics (body mechanics). Each trainee must gain a fundamental understanding of practical biomechanics so as to apply them in their activities of daily living, work and sport.
