Motion Dynamics Flashcards
What does the coronal plane split the body into?
Bisects the body into front and back halves
What does the sagittal plane split the body into?
Bisects the body into right and left halves
What does the transverse plane split the body into?
Divides the body into Superior and Inferior halves
ROM in Sagittal?
Flexion and extension
ROM in Coronal?

Example of a Hinge Joint?
Elbow
Describe an Elastic End feel
like a rubber band
Describe an Abrupt End feel
osteoarthritis or hinge joint
Describe an Hard End feel
somatic dysfunction
Describe an Empty End feel
stops due to guarding (patient doesn’t allow the motion due to pain)
Describe an Crisp End feel
involuntary muscle guarding as in pinched nerve
What is static ROM?
maximal ROM a joint can achieve with an externally applied force
What is a dynamic ROM?
ROM an athlete can produce and speed at which he/she can produce it
Which spine section has the greatest motion?
Cervical
What is coupled motion?
consistent association of a motion along or about one axis, with another motion about or along a second axis.
