Core Stability Muscles
The deep core stability muscles of the lower spine include:
- Transversus Abdominis (TA)
- Multifidus (MF)
- Pelvic Floor (PF)
The Transversus Abdominis (TA) is the deepest abdominal muscle. It is the “corset muscle” of the spine and pelvis. In the typical situation, TA contracts in anticipation of body motion to guard the spinal joints, ligaments, discs and nerves.
Multifidus (MF) muscles are very short muscles running from the transverse processes (on the sides) of one vertebra up to the spinous process (the middle of the back) of the next vertebra upwards. Their primary function is back stability. They do not produce an extensive range of movement, but work to provide small, “fine-tuning” postural changes, all day long.
Pelvic Floor & Diaphragm
The TA and the MF work in conjunction with your pelvic floor and diaphragm to make a flexible but stable region around your lumbar spine. This ability to stabilise your lumbar spine in its many positions enables you to overcome back problems and reduce your chances of a reoccurrence.
