16
Q

manipulation vs mobilzation

A

fast forceful vs slow able to be stopped

17
Q

ovoid

A

convex into concave relationship

18
Q

sellar/saddle shaped joint

A

both joint surfaces have concave one way and convex the other

19
Q

Roll

A

type of arthrokinematic motion, rolling of one joint surface on another

20
Q

Glide

A

1 point on a joint surface going over new points on the adjacent surface

21
Q

spin

A

spinning of the movable joint surface on the fixed adjacent surface.

22
Q

concave-convex rule

A

convex surface moves in the opposite direction of the body segment’s motion
are abducted ^ convex surface v
Concave surface moves in same direction
Finger extended ^ concave surface ^

23
Q

a joint is Congruent/Close-packed

A

joint surfaces have max contact with each other, conpressed, and are difficult to separate

24
Q

a joint is in resting position/open-packed

A

parts of capsule/supporting ligaments lax, minmal congruency between articular surfaces. Joint play/accessory motions can occur in this position

25
Q

Accessory motion forces

A

traction/distraction/tension, approximation/compression, shear, bending

26
Q

Shear force

A

results in a glide motion
