Intro Flashcards
Joint mobilization
Passive modality that takes a joint through its accessory movements to restore pain-free ROM and joint nutrition.
To assess, treat, and maintain.
Joint play
Movement available when a joint is in some degree of loose pack and can be assessed
Osteokinematic movement
Physiological movement, referring to the distal ends of the bones of a joint.
Arthrokinematic movement
Movement at the articular surfaces
Done passively
Accessory movements are arthrokinematic
Accessory movements (aka component movements)
Particular arthrokinematic movements in which one bone moves on another.
Ex- glide, roll, spin
Roll direction
Same as bone movement
Glide direction
Concave moving on convex: same direction as osteokinematic
Convex moving on concave: opposite direction of osteokinematic
Spin
Spin on mechanical axis while maintaining constant contact at a particular point on treatment plane.
Ex- pronation/supination of radius on ulna
Treatment plane
Plane superimposed on concave articulating surface of a joint
Mechanical axis
Perpendicular to treatment plane
Close-pack position
When articulating surfaces are most closely approximated, and involves a rotational component
Joint mobes CId
Loose-packed position
Any position outside of the close-pack position
Joint mobes performed here
Resting position
Maximum loose-pack position
Ideal for joint play assessment and early treatment
Capsular pattern of restriction
Specific restriction patterns characteristic of a joint when an entire joint is impaired. Different for each joint.
Concave/convex rule
When concave moves on convex: glide and roll same direction
When convex moves on concave: glide moves in opposite direction of roll
