What is a Ring?

Mar 10, 2022

Do you ache somewhere in your ribcage or back?  Perhaps between your shoulder blades?  Do you feel restricted when you twist like when reversing the car, swinging your golf club or running? Do you feel limited when taking a big breath or perhaps it feels asymmetrical?  These are all things we hear you say all the time and are symptoms of non-optimal things going on in your ribcage or “thorax” as we call it.


Patients will commonly have already noticed asymmetries in their thorax before they come and see us, regardless of where their symptoms are.


If you aren’t sure, go find a mirror and have a look!  Some examples of things you may notice are;

  • one shoulder is lower or higher than the other
  • your chest faces more to the left of the right and doesn’t face forwards
  • there are more pronounced regions on the front of your chest that no one can explain to you
  • You can see more pronounced ribs on one side more than the other
  • You see your tummy and waist looks asymmetrical
  • Your nipples are not at the same level
  • Your tummy button isn’t sitting in a straight line down from your chin to your pubic bone. It may look more to the left of right.
  • A more rounded lower tummy and more active upper tummy just below your ribs.

Did you see anything?  Most of us have one or even all of these things, all of which are signs that your thorax is not optimal.

It has been a common belief that the ribcage is a rigid box that protects the vital organs that lie within it.  From a Physio perspective we have been used to treating the ribs and spine in this region separately with focus on the joints.  Are they stiff or how much do they move?

What we understand now thanks to the research of Dr LJ Lee ( is that this view of the ribcage is not the case and we as Physio’s need to radically change our thinking,  assessment and treatment of this region.  Your ribcage is actually made up of 10 rings stacked on top of one another making up a slinky.  Because the connections that join the vertebra and ribs and chest bone are so strong they form a circle,  a functional unit that we call a “ring”. Each ring has 13 joints in it and is made up of the rib on each side and the adjacent vertebra that they join to.  Movement of a rib therefore has an impact on the vertebra in that ring.

If you are trying to assess the whole ring in space and where it is relative to your feet and your centre of mass,  only feeling from the back and feeling the vertebra and back of the ribs  (as we have traditionally done) isn’t going to give us very accurate information on what is happening throughout the whole ring.  Rings should be stacked on top of one another like a lovely stack of plates.  But,  when this region is non-optimal we feel rings that are more translated and rotated to one side,  rings that are compressed and squished into the ones below or above, rings that are more forwards or rings that move more compared to other rings.

So,  when assessing this region we need to feel at the sides of each ring to get way more information about what is going on in the whole unit.  Your ribcage starts just below your collar bone so we will need to feel all the way up into your armpits!

By feeling the sides of each ring we can assess several things;

  • where each ring in your slinky is relative to your feet
  • where each ring is relative to the ring above and below it

THEN and most importantly,

  • What happens to each ring when you move compared to what should be happening.

What we also know from research and further work from Dr LJ Lee is that the thorax is actually a relatively flexible region of the body.  Remember there are 13 joints in each ring and joints move.  Movement needs to be controlled and this control comes from the nervous system and the muscles they innervate.  For more on this read our blog ‘Putting a Spring in Your Step’.

So, your “One Thing” to do this week is go and have a look at your body most specifically your trunk and ribcage. Check for the non-optimal signs above that your rings are stacked! See what you find.

Remember, as we have said before, your ribcage can be causing pain and problems anywhere in your body.  Treating your thorax has never made more sense than with the Thoracic Ring Approach™.  For more information please get in touch and also check out LJ’s website which is geared towards Physio’s but also has heaps of information that will make a whole lot of sense to you!
