Intrinsic Stabilization Subsystem (ISS) Integration

This course describes the intrinsic stabilization subsystem (ISS). This subsystem may also be referred to as intrinsic core muscles, deep core muscles, intrinsic stabilizers, stabilizing system, local stabilizers, lumbar stabilizers, and is related to the terms muscle sling, myofascial sling, myofascial synergy, oblique sling, core subsystem, myofascial lines, myofascial trains, anatomy trains, myofascial meridians, and deep front line. This course covers a detailed analysis of the intrinsic stabilization subsystem (deep core muscles) including anatomy, research, integration techniques and a sample routine.

The Intrinsic Stabilization Subsystem is comprised of:

• Transverse Abdominis (TVA)
• Internal Obliques
• Pelvic Floor (Levator ani, coccygeus, and associated fascia)
• Diaphragm
• Multifidus
• Rotatores, Interspinales & Intertransversarii
• Abdominal Fascia (posterior layer)
• Continuous with investing fascia of Diaphragm and Pelvic Floor
• Thoracolumbar Fascia (TLF) (anterior and middle layer)
  • Potentially
    • Quadratus Lumborum
    • Psoas

The concepts and techniques described in this course may be particularly beneficial for neuromuscular re-education, coordination, motor pattern integration, whole-body strength, functional strength, and sports performance. Sports medicine professionals (personal trainers, fitness instructors, physical therapists, massage therapists, chiropractors, occupational therapists, athletic trainers, etc.) should consider adding these exercises to their repertoire to improve the outcomes of their integrated exercise programs, sports performance programs, and therapeutic (rehabilitation) interventions.
