The document discusses common referred pain patterns associated with lumbar somatic dysfunctions, highlighting that pain can radiate from specific lumbar levels to various regions, such as the groin and lower extremities. It emphasizes that approximately 40% of low back pain originates from facet joints and details the involvement of paravertebral muscles and visceral organs in referred pain. Additionally, it provides a bibliography of relevant studies and references on the topic.

Lumbar somathic dysfunctions can cause referred pain elsewhere:
• Pain radiating to the buttock or trochanteric region occurred mostly from the L4
and L5 levels, while groin pain is produced from L2 to L5.
• The nerves supplying the facet joints give rise to distal referred pain
significantly more commonly than the joints themselves. Let’s not forget that
some 40% of the causes for low back pain come from the facet joints.

The paravertebral muscles can also refer pain. In the case of paravertebral muscle
involvement the pain refers lateral of the involved muscles and downwards, even
going into the leg, posterior or lateral side. Anterior referent patterns on the anterior
crista and inguinal ligament are reported as well as lots over overlap patterns.

3. Periostal pain in the pelvic region and lower extremity can also come from
lumbar spine dysfunctions:
• The upper part of the ilium: from T12 – L4.
• The middle part of the ilium: from L2-4.
• The lower part of the ilium: from L2-5.
• The sacrum and coccyx area: from S1-5.
• Femur: from L3-5.
• Below the knee: from L4-5.
• Foot: from S1-2.
Pain arising from the lower intervertebral discs (L4-5 and L5-S1) can give referred
pain in the lower extremity, even below the knee.
Visceral referred pain also occurs in the lumbar area:
• Dysfunctions from kidney, ureter, pelvic organs, intestines can cause referred
pain in the lumbar area through segmental irritation T12, L1, L2.
• Kidney problems can mechanically irritate parts of the lumbar plexus and
cause pain along the iliohypogastric, ilioinguinal, lateral cutaneous and
genitofemoral nerves.
