Principles of Thoracolumbar Spinal Motion Flashcards
When describing vertebral motion, what is the point of reference?
Superior anterior surface of the vertebral body (relative to structures below)
Vertebral extension is described as movement about a ________ axis.
Transverse
The spine ________ the spinal cord and serves as a structure of ________.
Protects, support
Vertebral flexion is described as movement about a ________ axis.
Transverse
Vertebral sidebending is described as movement about an ________ axis
Anterior-posterior
The first principle of thoracolumbar motion typically applies to ________ and usually involves imbalances in ________ or ________ muscles.
Multiple segments, large, postural
Vertebral rotation is described as movement about the ________ axis.
Vertical
The _______ segment of the spinal column guides and limits the direction of intervertebral motion.
Posterior
The ________ principle of spinal mechanics states that initiating motion of a vertebral segment in any plane of motion will modify the other planes of motion as well.
Third
Two adjacent vertebrae with all associated structures is known as a ________.
Vertebral unit
Fryette received his medical training at _______.
Chicago College of Osteopathic Medicine
A type II dysfunction usually only affects a _________.
Single vertebral unit
Following type I mechanics, rotation will be greatest at the ________ of a curve.
Apex
When diagnosed, somatic dysfunctions are named based on the direction of ________.
