Chapter 1 Neumann Flashcards
Getting started
Kinematics
Describes MOTION of a body without regard to the forces or torques that may PRODUCE THE MOTION.
Osteokinematics
Describes the MOTION OF BONES relative to the three cardinal planes of the body: Sagittal, frontal, and horizontal.
Degrees of freedom
The number of independent movements allowed at a joint. A joint can have up to 3 degrees of angular freedom.
Accessory motions
The slight passive translations that occur in most joints. They are defined in 3 linear directions.
Arthrokinematics
Describes the MOTION that occurs between the ARTICULAR SURFACES of joints.
Sagittal plane Osteokinematic Terms
Flexion and extension
Dorsiflexion and plantar flexion
Forward and backward bending
Frontal plane Osteokinematic Terms
Abduction and Adduction
Lateral flexion
Ulnar and radial deviation
Eversion and inversion
Horizontal plane Osteokinematic Terms
Internal (medial) and external (lateral) rotation
Axial rotation
Arthrokinematics Definition of Roll
MULTIPLE POINTS along one rotating articular surface contact MULTIPLE POINTS on another articular surface. EX: A tire rotating across pavement
Arthrokinematics Definition of Slide
A SINGLE point one 1 articular surface contacts multiple points on another articular surface. EX: A cartoon character digging their heels into the ground to stop and sliding a distance.
Arthrokinematics Definition of Spin
A single point on 1 articular surface rotates on a single point of another. EX: A toy top.
Convex-on-concave surface movement
The convex member rolls and slides in opposite directions
For a concave-on-convex surface movement:
The concave member rolls and slides in similar directions
Roll always follows the direction of what?
The movement
Kinetics definition:
Describes the effect of forces on the body. From a kinesiologic perspective, a force can be considered as a “push” or a “pull” that can produce, arrest, or modify movement.
