Research suggests that many back problems result from a combination of poor posture and body mechanics which create abnormal stress on the spine. This stress can eventually develop into structural changes in the spine which manifest as disc and joint degeneration, shortening or lengthening of support ligaments and muscles together with wear and tear on cartilage. All of these changes can lead to pain.

The key elements to keeping your spine healthy are learning and practicing good posture, using good body mechanics during everyday activities together with regular exercise.

The basis of effective back care begins with good posture. Poor posture can cause spinal pain as well as exacerbate existing pain, it can also delay rehabilitation. Poor posture has been associated with chronic headaches, Temporomandibular Joint Disorder (TMJ) and shoulder pain.

People spend hours during their daily activities lifting, bending forward and sitting. Consider your lifestyle, how many times during the day do you compromise your spine when lifting, bending, or sitting at your computer.
If you can master maintaining a neutral spine, retaining the three natural curves of the spine as you move from one position to the next you will be closer to protecting your spine from unnecessary stress and strain. It is clear that once the spine is placed in a neutral position it needs to be kept there and it is the postural muscles that achieve this.

The muscles that hold the spine in correct alignment are found deep in the body close to the spine they are referred to as stabilisers naturally, because this is their function, to help stabilise the spine in readiness for activity.

These deep abdominals respond most effectively to a gentle contraction and together with a neutral pelvic alignment and a lateral thoracic (wide and full) breath create the correct intra-abdominal pressure to assist with spinal stability. (Richardson et al 1996, Queensland University). Another good reason to locate and activate them.

The deep abdominals or postural muscles are also commonly called the core. The core, simply, is the muscles that connect your lower body to your upper body, it is made up of four major muscles:

The Transversus Abdominis (TA) The Pelvic Floor The Diaphragm The Multifidus

The transversus abdominis (TA) is the body's natural corset. It's the muscle you use to pull in your tummy when you walk along the beach! The T.A. connects at the left of the spine, wraps around the abdomen attaching to the ribs and hips, until it reaches the right side, encasing the internal organs. The more superficial abdominal muscles that give you a six pack are layered on top of these support muscles. However if you want those washboard abs., to stay flat you will need to work your core as well as trim the fat and work the more aesthetic muscles. Of course another important function of the TA is to assist with spinal stability which is essential for good posture.

The pelvic floor (PF) are those muscles you use when you need a toilet and can't find one. You will also be aware of them when you cough or sneeze as they tend to tense spontaneously under this pressure.

Unfortunately people generally do not pay enough attention to these important muscles. The PF is the structure, not unlike a basket that holds in and supports the abdominal organs, stablise the hips in association with the core and helps with balance as well as reducing the risk of stress incontinence.

(The diaphragm is a sheet of muscle that works with the muscles of the ribs to expand and contract the ribcage during respiration (breathing). We do not often take control of the diaphragm. The way we control our diaphragm is usually through breathing; rate, rhythm and depth, you don't focus on the muscle but the inhale and exhale. The stronger we make the diaphragm, however, the deeper, slower and more paced our breathing will be.

The multifidus runs the length of the spine, it has a unique design which provides support as well as keeping us upright by providing scaffolding for the vertebral column. Researchers for the National Institute of Health found short stiff muscles packed in a finger-like covering; it is this particular design that is responsible for the extra strength and support the multifidus gives the spine.

Unlike most muscles when the multifidus is on stretch, (when we bend forward) it gets stronger. Generally if a muscles is lengthened it has a tendency to lose strength. Obviously the multifidus is operating under different rules.

("Our research shows that it's the strongest muscle in the back because of its unique design" states Richard L. Lieber, PhD. Lieber is the director of the National Center for Skeletal Muscle Rehabilitation Research, a professor and Vice Chair at UCSD's Department of Orthopedic Surgery, and a senior research scientist at the VA in San Diego.

It is clear from the information above that learning to utilise the core to initiate movement whilst in a neutral pelvic alignment will not only reduce your risk of injury and low back pain but go a long way towards improving your general posture.

You now have all this information and are aware of the value of neutral spine, using your core and breathing properly, so how can you use it?

When you are participating in your sport of choice, or exercise class, initiate all movement by using this simple system: Set the bones - Neutral Pelvis. Engage the muscles, the core and use a wide and full breath. Once you have initiated this set up you are ready to add the more superficial muscles that will move your body into action.

The muscles of the core only need a mild contraction to become activated and function effectively (Richardson et el 1996) much like a light switch, they are either on or off. Once they are on you can confidently use the large muscles for the action phase of a movement now that you have stabilised the spine and reduced the effects of stress on the spine from the activity. Try this test exercise:

Lay on your back on a mat or towel with your knees bent and feet hip width apart.

Allow your complete spine to "let go" of tension

Roll your pelvis backward and forward to find the range of movement

Place your pelvis half way between the two extremes (neutral alignment)

Exhale and gently draw your naval inward

"gently" if level 1 is no contraction and 10 is the maximum draw into level 3

Try to maintain this alignment with a gentle contraction whilst you slide your right foot along the ground, keep this a closed chain activity, with your foot always in contact with the floor

Only slide your foot as far forward as you can maintain the neutral spine, level 3 contraction of the core whilst you breathe naturally.

Repeat the movement up to 5 times on the right foot, then change to the left. This simple test of challenging your ability to move your limbs whilst maintaining the set up will demonstrate to you the subtlety of the action.

I recommend that until you are satisfied that you have your neutral set up and can maintain minimal involvement of the superficial abdominal muscles when working with low load (sliding the foot) you do not complicate matters by practicing more challenging abdominal exercises.

The purpose of first working in such a non challenging manner is to fully understand the "feeling" of the core connection. Once you are confident of course you will utilise this stabilising activation as the foundation to all abdominal exercises. Use the neutral set up as the start and finish of a movement; throughout the activity you will ensure the deep abdominals remain engaged so that all abdominal exercises are effective.

Of course you do not spend all your time exercising, throughout your day you will need to think about the value of stabilising your spine. Picking up your child for example, or taking luggage from the boot of the car require your deep abdominals to be stable before you complete the lift. The most stress is placed on the spine when it is flexed (bent forward) and loaded (lifting). Reduce your risk of injury and take a second to activate your core when necessary.

Briefly, good posture is awareness and persistence. Poor posture takes a lifetime to manifest and will take time and effort to rectify. However, perfect practice makes perfect , soon you will find your neutral alignment to be "natural".

The benefits are not only reduced risk of injury and reduction of low back pain, but a lengthened body appears slimmer and good posture can take 10 years off your age. So what are you waiting for? Start today.
