Flashcards in Kin 4 Arthrokinematics Deck (26):
1

End feel

Quality of the feel at the end of the joints passive ROM

2

Bony End Feel

hard abrupt limit

3

normal Soft Tissue Stretch/Firm End Feel

firm with slight give limit

4

Soft tissue approximation/Soft end feel

muscle bulk limits

5

abnormal Bony End Feel

hard stop well before normal end of ROM

6

Boggy End Feel

soft wet sponge feel (soft tissue edema is present)

7

Muscle Spasm

a protective reflexive muscle guarding during range

8

Empty end feel

pt will not let you move it due to pain

9

springy block

rebound movement at end of ROM (usually occurs with internal derangement of a joint i.e. torn cartilage)

10

Arthrokinematics

joint surface motion

11

Osteokinematics

Joint motion

12

Component movements

happen with active motion but involuntary

13

Joint play (accessory motion)

passive moving between joint surfaces started by an external forced being applied

14

joint mobilization (accessory motion)

constant stretch at slow speed, where pt could stop motion if they needed to

15

Joint manipulation (accessory motion)

quick passive motion applied externally, that can't be stopped

16

manipulation vs mobilzation

fast forceful vs slow able to be stopped

17

ovoid

convex into concave relationship

18

sellar/saddle shaped joint

both joint surfaces have concave one way and convex the other

19

Roll

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

20

Glide

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

21

spin

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

22

concave-convex rule

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

a joint is Congruent/Close-packed

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

24

a joint is in resting position/open-packed

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

25

Accessory motion forces

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

26

Shear force

results in a glide motion
