Muscles

Quadratus lumborum

One of the most common muscular sources of low back pain — deep, hard-to-localize pain that worsens with standing.

Referred pain map

Quadratus lumborum
Quadratus lumborum — superficial trigger points along the 12th rib and iliac crest, and deep trigger points nearer the lumbar transverse processes.
Quadratus lumborum
Superficial QL trigger points refer to the iliac crest, greater trochanter and lateral hip — a classic 'hip pain' that is actually low-back in origin.
Quadratus lumborum
Deep QL trigger points refer pain to the sacroiliac joint and buttock, a common source of persistent, hard-to-localize low back pain.

Overview

Runs from the 12th rib and lumbar transverse processes to the iliac crest. Side-bends the lumbar spine, hikes the hip, stabilizes the pelvis during breathing. Frequent silent contributor to chronic low back pain.

Trigger point locations

Superficial points along the iliac crest and 12th rib attachment, plus deeper points medially along the lumbar transverse processes.

Referred pain pattern

Iliac crest, sacroiliac joint area, greater trochanter, sometimes lower abdominal pain. Often described as a deep, dull lumbar ache.

Palpation & testing

Side-lying with the upper arm overhead to open the flank. Palpate between the 12th rib and the iliac crest, lateral to the paraspinals.

Common causes

Leg length discrepancy, asymmetric loading, sustained sitting in a twisted position, lifting with rotation.

Self-care & clinical treatment

Side-bend stretches over a foam roller, address pelvic asymmetry, diaphragmatic breathing. Clinically: needling, lateral decubitus manual release.
