Semispinalis capitis, pectineus, & vastus lateralis are unusual suspect muscles, often overlooked by manual therapists, that can cause pain and dysfunction.
Transversospinalis in the Laminar Groove
The transversospinalis musculature is extremely important functionally, and important with pain and dysfunction. It includes the multifidus, the thickest muscle of the low back; and the semispinalis capitis, the thickest muscle in the back of the neck. When working this musculature, it is extremely important to work very far medially, over the laminar groove of the spine.
Semispinalis Capitis: The Unusual Suspect Behind Your Neck Pain
The semispinalis capitis is the largest muscle in the back of the neck — and the most overlooked cause of posterior neck pain. Learn how to assess, palpate, stretch, and massage it.
Muscles of the Lumbar Spine of the Trunk
Structural groups of muscles largely determine functional groups—that is, the structural location of a muscle largely determines its mover function.
Five Muscles of Sacroiliac Stabilization – Part 3 – Hamstrings
