Overview 2 parallel vertical axises (red circles/lines in images below) 1 through the foramen magnum (occipital bone, purple bone below) 1 through the body of the sphenoid (white bone below) Sphenoid and occiput rotate in the same direction about their vertical axises (clockwise, counterclockwise) Naming The naming of a vertical strain […]

Overview 2 parallel transverse axes (red lines in images below) 1 axes through the sphenoid bone (purple bone below) 1 axes through the occipital bone (white bone below) Naming The naming of a vertical strain is based on the position of sphenoid base in relation to occiput (superior or inferior). […]
Overview Results from compression of the sphenoid and occiput at the SBS junction Etiologies Trauma (back/front of head) Circumferential compression (childbirth) SBS Compression Hand Motion Skull Motion
Who came up with Osteopathy in the Cranial Field? William Garner Sutherland What are the five body components of PRM (primary respiratory mechanism)? The inherent motility of the brain and spinal cord (CNS) Fluctuation of the cerebrospinal fluid (CSF) Mobility of the intracranial and intraspinal membranes (RTM) Articular mobility of […]
Overview All cranial movements are named for the movement of the sphenobasilar synchondrosis (SBS), the articulation of the sphenoid bone and occiput This movement is the palpable Cranial Rhythmic Impulse This is the basis of the physiologic strain patterns and pathologic strain patterns Skull White Bone = Sphenoid Purple Bone […]
Overview Pathologic strain patterns are abnormal strain patterns and require treatment The 3 types of pathologic strain patterns are: Vertical Strains Lateral Strains Sphenobasilar Compression In a lab setting, you will be asked to demonstrate these motions using your hands On a written or oral exam, you may be asked […]
Overview Number of Axises = 3 Type of Axis Sidebending – 2 parallel vertical axises 1 through foramen magnum (occipital bone) 1 through body of sphenoid Sphenoid and occiput rotate in opposite directions about vertical axes (clockwise, counterclockwise) Rotation – 1 Anteroposterior (AP) axis AP axis through the sphenoid and […]
Overview Number of Axes = 1 Type of Axes = 1 Anteroposterior (AP) axis through the sphenoid and occiput The sphenoid and occiput rotate in opposite direction about this single AP axis Naming The naming of cranial torsions is based on the side with the higher wing of the sphenoid […]
Overview 2 parallel transverse axes (red lines in images below) 1 axes through the sphenoid bone (purple bone below) 1 axes through the occipital bone (white bone below) Naming The naming of cranial flexion/extension motion is based on flexion or extension of the midline bones of the skull (sphenoid, occipital, […]
Overview Physiological strain patterns are “normal” types of cranial motion The 3 types of physiologic motions are: Flexion/Extension Torsions Sidebending/Rotation In a lab setting, you will be asked to demonstrate these motions using your hands On a written or oral exam, you may be asked to indicate the number of […]
The Position The student doctor is seated at the side of the head of the table with the patient placed in a supine position. With his/her forearm resting on the table, the student doctor advances his/her caudad hand under the patient’s occiput. This establishes a fulcrum. With his/her elbow resting […]
Flexion / External Rotation Coronal Diameter – increases (widens) Anteroposterior Diameter – decreases Height – decreases Extension / Internal Rotation Coronal Diameter – decreases Anteroposterior Diameter – increases (widens) Height – increases Normal CRI CRI = Cranial Rhythmic Impulse Normal Amplitude of CRI is 8-14 cycles per minute For a […]
The Position The student doctor is seated at the head of the table with the patient placed in a supine position. Position the patient far enough down on the table so the student doctor can rest his/her forearms on the table. The student doctors places their hands on the patient’s […]
