Looking at the psoas major from a biomechanical perspective might be the key to understanding this elusive and controversial muscle.
Psoas Major Function: Hip Joint Actions – Sagittal Plane
Note: This is the third blog post article in a series of 11 articles on Psoas Major Function. See below for the other articles in this series on psoas major function. The hip joint is a triaxial joint that allows …
Psoas Major Function: Hip Joint Actions – Frontal Plane
If the psoas major frontal plane open-chain action is abduction of the thigh at the hip joint, the closed-chain action is depression of the pelvis.
Psoas Major Function: Biomechanics of the Psoas Major
The psoas major is first and foremost, a muscle of the hip joint; however it is more complicated because it also crosses the spinal joints.
Psoas Major Function: Introduction & Muscle Biomechanics
The Psoas Major may hold the distinction of being the most important as well as the most misunderstood muscle in the human body.
Obliquus Capitis Inferior – A Misnamed Muscle
The emphasis of this article is on the importance of the naming of muscles, highlighted by the fact that the obliquus capitis inferior (OCI) is misnamed. However, the OCI is an important muscle in its own right. Given the prevalence of locked-short musculature in the posterior neck, especially in the supoccipital (upper neck) region, the OCI is extremely important clinically.
Motions of the Cervical Spine
Table 1 shows average healthy ranges of axial motion of the cervical spine (head and neck), from the atlanto-occipital joint through the C7-T1 joint.
Cervical Spinal Joints
The disc joint is a cartilaginous joint that is composed of outer fibers called the annulus fibrosus that encircle the inner nucleus pulposus.
Brachialis – The First Muscle You Should Learn
Learn everything about the brachialis muscle — its attachments, open- and closed-chain functions, how to palpate, stretch, and massage it. The perfect muscle for teaching kinesiology biomechanics.
Piriformis – An Essential Muscle for Manual Therapists
Learn everything about the piriformis muscle — attachments, open- and closed-chain functions, piriformis syndrome, palpation, stretching, and massage techniques for manual therapists.
Brachioradialis – A Fascinating Study in Muscle Mechanics
Learn the brachioradialis muscle’s attachments, open- and closed-chain functions, palpation technique, and why it’s the ultimate example of a muscle that changes its joint action with joint position.
Introduction to the Cervical Spine
It is extremely important to be able to locate and palpate the laminar groove of the cervical spine because the thickest musculature is located there.
Coracobrachialis: Attachments, Functions, Palpation & Treatment
The coracobrachialis is a muscle in the anterior compartment of the upper arm. It originates on the coracoid process of the scapula and inserts on the medial shaft of the humerus. It performs flexion and adduction at the glenohumeral joint and serves as a key teaching muscle for core kinesiology concepts including open-chain vs. closed-chain movement, cardinal-plane vs. oblique-plane motion, and anatomic vs. non-anatomic actions.
What is Manual Therapy?
The following techniques are considered to be Manual Therapy techniques: Massage (Soft Tissue Manipulation), Stretching, Joint Mobilization, Hydrotherapy.
