14 Quadratus Lumborum

 

This module teaches the release of the Quadratus Lumborum, a stabilizing muscle along the side of the lumbar spine. Spasm in this muscle can produce sharp lower back pain and restriction between the rib cage and pelvis.

The quadratus lumborum (QL) is one of the primary stabilizers of the lower back.

It connects:

• the pelvis (ilium)

• the lumbar spine• the lower ribsIts role is to:• stabilize the spine during movement• assist in lateral bending

• control rib position during breathingWhen functioning properly:

• the spine remains balanced• movement is smooth and coordinated• the rib cage and pelvis move in harmony

 

When the QL enters spasm:

👉 it locks the lower back

👉 restricts lateral movement

👉 creates asymmetry in posture

 

This is often experienced as a deep, one-sided restriction.

Problem

Step 2
The Clinical Problem

Clients commonly present with:
• stiffness when standing upright
• discomfort when bending or twisting
• a feeling of imbalance

• lateral lumbar pain - pain on the side of the low back. Not on the front; not on the back; right on the side.

They may also notice:

• one hip appearing higher than the other
• difficulty standing evenly
• tightness along the side of the waist

A key observation:

👉 the body feels pulled to one side and cannot fully relax into neutral

Spasm of the quadratus lumborum causes side-pain in the lumbar region

Why

Step 3

Why This Happens

luggage.png

The quadratus lumborum is highly responsive to:

• postural imbalance
• compensation from other muscles
• uneven loading of the body

When the system becomes unbalanced:

• the QL engages to stabilize
• it works harder to maintain alignment

With repeated demand:

👉 it becomes overactive
👉 enters sustained contraction

Breathing Influence

Because the QL attaches to the lower ribs:

• it directly influences breathing mechanics

 

When in spasm:

• the lower rib cage becomes restricted
• breathing becomes asymmetrical

Releasology Perspective

This represents a disruption in lateral and posterior conduction.

Instead of allowing movement:

• the system becomes fixed on one side
• force is not distributed evenly

Anatomy

Step 4 
Anatomy

Quadratus Lumborum - Posterior View.png

The quadratus lumborum spans vertically along the lower back.

Attachments

Origin: ilium (hip bone)

Insertions:

Transverse process of L1 through L4 and inferior surface of 12th rib

Location

It sits:

• deep along the side of the lumbar spine
• between the rib cage and pelvis

It can be palpated as a thick, vertical band of tissue.

Palpation

Step 5
Palpation and Tissue Assessment

yeli quadi.png

Client Position

• prone or side-lying

Side-lying often allows easier access and better tissue response.

Contact

Place hands along the lateral lumbar region:

• between the rib cage and pelvis

Cross-Fiber Assessment

Move back and forth across the fibers:

• perpendicular to the vertical direction

Feel for:

• resistance
• density
• lack of glide

Tissue Quality

Restricted QL feels:

• dense
• thick
• resistant to pressure

Healthy tissue feels:

• responsive
• softer
• able to shift

Functional Observation

Observe:

space between the 12th rib and the iliac crest. When the quadratus lumborum is in spasm, the space between these two bones is minimized. Sometimes, so much that the 12th rib feels like it is touching the iliac crest and you can barely get your hand between these two bones. The space between these two bones is neither on the anterior or posterior of the body. Feel that the spinal muscles are much further in the back of the body. Also, through palpation, notice that the abdominal muscles are much more anterior than the muscle one you should be able to feel between the 12th rib and the iliac crest. This is always clearly the quadratus lumborum. Do you feel it? 

   

Observe:

• symmetry of the lower back
• rib movement during breathing

Restriction often presents as:

👉 one side moving less than the other

Neurological

Step 6
Neurological Consequences

When the QL is in spasm:

• the nervous system maintains protective tension
• movement becomes guarded
• asymmetry increases

Functional Effects

• reduced mobility
• uneven loading of the spine
• persistent low back discomfort

Systemic Influence

Because the QL stabilizes the spine:

• dysfunction here affects overall posture
• other muscles compensate
• patterns can spread throughout the body

Releasology Perspective

This is a disruption in lateral stability, respiration and conduction.

When in spasm, the quadratus lumborum also restricts breathing by locking down the bottom of the ribcage on the side. The quadratus lumborum is part of the gall bladder channel in Chinese Medicine and the air element segment of the Pinagala Nadi in Ayurveda.

Instead of balance:   

👉 the system becomes biased to one side

When released:

• symmetry returns
• movement improves
• the body re-centers

Technique

Step 7
Technique Demonstration

First Viewing — Flow

• where contact is made along the lateral lumbar region
• how the practitioner positions their body
• pacing of the technique

Second Viewing — Mechanics

• cross-fiber direction of pressure
• how depth is achieved without force
• body alignment and grounding

Observe the Release

• softening of the tissue
• improved movement
• visible relaxation

What to Look For

• areas of greatest resistance
• how contact is refined
• when the tissue begins to yield

Using a red drawing tool on your phone or tablet:

  1. Draw the attachments of the psoas major

  2. Fill in the lines to show the basic shape you think it looks like

  3. Use red lines and remember to draw them also to show the direction you believe the fibers of this muscle pass in.

  4. Review the surrounding neurological structures.

Treatment

Step 10 

Treatment Recording​

In this step you will record yourself performing the quadratus lumborum release technique, so your

form and body mechanics can be evaluated.

Yelimar QL.png

You will need:

• a massage table or treatment surface
• a practice subject
• a tripod or stable support for your phone or camera
• good lighting so your hand placement is clearly visible

Position the camera so that the following are clearly visible in the video:

• your hand placement on the client
• your body mechanics and posture
• the direction of pressure you apply
• the client’s neck and shoulder region during the release

The video should show the entire treatment sequence, from initial contact to release.

Record yourself performing the quadratus lumborum release technique so your form and body mechanics can be evaluated.

☑ correct finger placement

☑ practitioner body mechanics

☑ the Yang engagement phase

☑ the Yin release phase

 

The video should show the full treatment sequence from initial contact to muscle release.

 

Upload your video for instructor review.

Your instructor will confirm that the technique is performed safely, accurately, and according to the Releasology method.

This step allows your instructor to confirm that the technique is being performed safely, accurately, and according to the Releasology method.
