18
Q

two degrees of freedom

A

joint moves around two axes, and in two planes

19
Q

examples of two degrees of freedom

A

biaxial, condyloid (MCP), ellipsoidal (radiocarpal joint), saddle (CMC) joint of thumb

20
Q

example three degrees of freedom

A

triaxial, ball and socket, circumduction

21
Q

3 types of joints

A

synarthrosis, amphiarthrosis, and diathrosis

22
Q

synarthrosis

A

fibrous (radius and ulna), stability and shock absorption, very slight movement (skull)

23
Q

amphiarthrosis

A

cartilaginous, stability w specific and limited mobility, limited (knees, spine)

24
Q

diarthrosis

A

synoval joint w ligaments, mobilty based of DOF

(OTs work to increase stretch here)

synovial joints are elbow/knee/shoudler/hip!

25
Q

what motions are of diarthrosis?

A

nonaxial/uniaxial/biaxial/triaxial

26
Q

end feel

A

resistance felt (palpation) by therapist when joint has been moved as far as it can go

27
Q

hard/bony end feel

A

motion is stopped by bone

28
Q

firm/capsular end feel

A

springy feel at end range secondary to joint capsule

29
Q

soft/end feel

A

when one muscle belly runs into another (hamstrings)

30
Q

pathological end feel

A

different end feel not associated w that joint, or area that is not typical

31
Q

empty end feel

A

pathological end feel that has pain at end feel but not resistance

32
Q

closed kinetic end chain

A

prox to distal

33
Q

open kinetic end chain

A

distal to prox

34
Q

arthrokinematics

A

relationship between 2 articulating joint surfaces when movement occurs

35
Q

osteokinematics

A

voluntary movements of shafts of the bone

36
Q

diathrodial(synovial) joints anatomy

A

cartilage/ligaments/articular discs/joint capsule/synovial fluid/bursa

37
Q

thicker, dense irregular fibrous tissue, protection/stabilizes joint, afferant proprioceptors that relay changes in the joint to CNS

A

diathrodial(synovial) joints anatomy: outer layer

38
Q

thinner, vascular, and produces and secretes synovial fluid into the joint space

A

diathrodial(synovial) joints anatomy: inner layer

39
Q

all joint surfaces are what two shapes??

A

ovoid (egg) or sellar (saddle) shaped

40
Q

ovid is what shape in females

A

concave

41
Q

example of sellar (saddle) shaped joint

A

CMC of thumb, sternoclavicular, talocrucal joints

42
Q

basic arthrokinematic joint motions

A

rolling/rocking, sliding/gliding, spinning

43
Q

what is the convex-concave principle?

A

if a bone w a convex joint surface moves on bone w concave surface, the convex joint surface slides in the direction opposite to the bones segment’s rolling motion

44
Q

joint considerations

A

hypermobile, hypomobile

open-packed joint position (open to move)

closed-packed joint position (perfect match)

instanenous axes of rotation- delta w glide and roll
