What is a locked-in spine?
Your back is designed to be the strongest when it is in its natural S position. This
means a slight curve in the neck, a slight curve out at the midback, and a slight
curve in at the low back. Combine this S position with a tightened abdominal core
and you have the locked-in spine.
We believe your back is most vulnerable to injury when it is in the C position.
Whenever you put your back into the C position, you are placing increased stress
on many of the structures of your back. This stress can cause the discs to deform
(as we previously demonstrated with the ball and vertebra example). However, it
can also cause the ligaments to stretch out and lose their stability. Ligaments are
tough bands that connect bone to bone.
When you are in the C position you are placing a continuous stress on your
ligaments. The following is a simple demonstration used by physical therapists to
illustrate how that stress feels. Grab your ring finger and stretch it back. You are
stretching ligaments (among other things). This discomfort increases if you bring
your finger back further and further, as well as if you keep the pressure
continuous.
Eventually overtime the ligaments holding the bones in your finger together may
stretch out and lose the ability to hold your hand bones in a stable manner. This
occurs in massage therapists who overwork their fingers and hands. The result is
more instability and pain.
Is the locked-in spine good for you?
When your back is in the S position, the back muscles are in an optimal position to
contract and protect your back. Watch a weightlifter as they perform squats with
hundreds of pounds of weight on their backs. Note how straight their backs are
as they maintain an S curve. Weightlifters with good form will keep their backs
straight, while most of their movement comes from their hips. This is often referred to as hip hinging. The S curve combined with abdominal tightening can protect your spine.
How to obtain a locked in spine?
First, place your spine in the S position. Use a broomstick or BOOYAH Stik to help obtain proper alignment. The stick should have 3 points of contact if done correctly, which include back of head, mid back, and pelvis. The C position only has one point of contact, which is the midback.
You should think of your back as though it is in a cast “locked in” to the S curve. All movement should come from your hips.
Once in the S position and before you perform a task such as lifting, tighten your abdomen. How do you tell if you are tightening your abdomen? Take a single finger from each hand and poke yourself on each side of your abdomen (belly). Tighten up your abdomen. If you are doing it correctly you should be able to feel your abdomen tighten with your fingers.
If you have increased pain in your back with the locked in position, try adjusting the arch in your low back (with more or less of an arch). Re-tighten your abdomen and try bending forward again. If it still increases your back pain, try to not bend forward as far.
The locked-in spine position should be performed throughout a typical day in your life to help protect your spine.
