Iliocostalis Lumborum Trigger Points
Symptom Area: Lower Torso
Iliocostalis Lumborum Trigger Points are explored here through their location and referred pain pattern. Muscle knots is an everyday term used for tender muscular spots; myofascial pain describes pain involving muscle and its surrounding connective tissue. Erector spinae extending the lumbar spine; assists side bending.
Where you feel it
When the Iliocostalis Lumborum holds active trigger points, you usually notice it as appendicitis-like pains, bloating/nausea/abdominal cramps, buttock pain, low back pain and si joint pain (base of the spine). Where the pain spreads: Lower back pain along the iliac crest, sometimes wrapping to the lower abdomen. What often sets it off: Prolonged sitting, repetitive bending, asymmetric loading.
Overview
Erector spinae extending the lumbar spine; assists side bending. Trigger points here are common in everyday and athletic populations and frequently contribute to the referred pain patterns described below.
Trigger point locations
Lateral lumbar paraspinal column.
Referred pain pattern
Lower back pain along the iliac crest, sometimes wrapping to the lower abdomen.
Palpation & testing
Palpate the muscle belly along its accessible course. Reproduction of the patient's familiar pain on palpation supports involvement.
Common causes
Prolonged sitting, repetitive bending, asymmetric loading.
Self-care & clinical treatment
Trunk mobility, hip hinge retraining. Clinically: needling, manual release.
Treatment protocol
For Iliocostalis Lumborum, the general protocol applies: sustained pressure release on the taut band, then stretch and active movement in the newly gained range.
Position and palpation: Palpate the muscle belly along its accessible course.
Regional precaution for clinicians: In the flank and abdominal wall the kidney (behind the twelfth rib and the quadratus lumborum), the abdominal viscera and the lower lung fields are the structures at risk.
