Intrinsic Stabilization Subsystem (ISS) Course

Intrinsic Stabilization Subsystem (ISS) Course is organized by Brookbush Institute.

Course Description:
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.

Behavioral Objectives
• Students will be prepared to pass a final exam by choosing from a list of potential answers to behavior-objective matched multiple-choice questions.
• Identify ISS under-activity using the Overhead Squat Assessment and Abdominal Drawing Maneuver
• Describe the concentric, isometric and eccentric functions of the ISS
• Design a corrective routine including a core exercise with the intent of targeting the ISS
• List the structures that comprise the Intrinsic Stabilization Subsystem
• Explain the findings of at least 4 research studies that have led to the description of an ISS and how it may influence intervention
• Deduce/synthesize a hypothesis regarding the effect this technique will have on outcome measures and the appropriate test for re-assessment.
• Design an intervention plan including these techniques with the intent of affecting an objectively measured functional outcome.
• Describe the functional benefits (including impact on performance, occupation or daily tasks) that may be expected from implementing the intervention plan.
