Core muscle groups

The core is a collection of muscles which stabilize and move the spine.

The inner core is comprised of the diaphragm, pelvic floor, multifidi, deep cervical flexors, and transverse abdominus. These muscles engage first during movement or breathing to protect the spine.

The outer core muscles are also responsible for stabilizing and protecting the spine, but they also have more defined movement functions. The abdominals are the most well-known members of the outer-core

Examples of major core muscle groups that respond well to motor nerve stimulation are:

  • Abdominal - a group of 6 muscles extending from the ribs to the pelvis; including the transversus abdominis and the rectus abdominis

  • Diaphragm - is a sheet of internal skeletal muscle that extends across the bottom of the thoracic cavity

  • Erector spinae - a paired muscle that runs more or less vertically throughout the lumbar, thoracic and cervical regions, and lies in the groove to the side of the vertebral column

  • Gluteal  - 3 muscles that make up the buttocks

  • Obliques - external and internal muscles located at the side and front of the abdomen; small in size and often obscured by deposits of fat

  • Pelvic Floor - muscles and tissue spanning the area underneath the pelvis

If muscles are wasted or weakened, start slowly and build gradually. As a general guide follow one of the tables below, depending upon which unit you have purchased. As the muscle group becomes stronger you build gradually by:

  • Increasing the intensity to give stronger contractions (from Medium to Medium-High and then High)

  • Using longer contract and release times (but release always twice as long as contract)

  • Applying for longer duration time each session

  • Repeating the program more often

  • Always allow a rest day between strenuous exercise sessions
