Your core muscles help to provide stability to your spine and are made up by anterior and posterior regions as well as a top and a bottom. The top is comprised of your diaphragm and the bottom is your pelvic floor. The anterior portion, also known as the abdominals, include your transverse abdominis, rectus abdominis, and internal and external obliques. The posterior portion, or the muscles along the spine, are made up of the erector spinae and a deeper layer of muscles called the multifidi. These muscle groups all work together to stabilize your spine. Strengthening both your superficial and deep spine stabilizers through structured physical therapy and therapeutic exercise training is imperative to prevent and treat chronic low back pain.
