Ch 4 Arthrokinematics

Question 0

End feel

Answer 0

Subjective assessment of quality of the feel when slight pressure is applied at the end of a joints passive range of motion

Question 1

Osteokinematic motion

Answer 1

Flx, ext, and,add, rotation

Joint movement on another

Question 2

3 types of normal end feel

Answer 2

Bony, soft tissue stretch, soft tissue approximation

Question 3

Normal bony end feel

Answer 3

Hard and abrupt limit to passive joint motion

Ex: extension of elbow

Question 4

Soft tissue stretch

Answer 4

Firm sensation that has slight give when the joint is taken to end rom
MOST COMMON end feel

Question 5

Soft tissue approximation

Answer 5

When muscle bulk is compressed stopping joint motion

Question 6

Abnormal bony end feel

Answer 6

Sudden hard stop usually felt well before the normal end of rom

Question 7

Boggy end feel

Answer 7

When soft tissue edema is present (ankle sprained)

Question 8

Muscle spasm

Answer 8

Reflexive muscle guarding during motion

Question 9

Empty end feel

Answer 9

No mechanical limitation of rom in joint. Pain is thinly thing that stops it.

Question 10

Springy block

Answer 10

A rebound movement is felt at rom

Usually torn cartilage

Question 11

Arthrokinematic motion

Answer 11

Adjoining joint surfaces move on each other during osteokinematic joint movement
Joint surface motion

Question 12

Joint play

Answer 12

Passive movements between joint surfaces done by passively applying external force

Question 13

Convex concave rule

Answer 13

Concave on convex moves joint in same direction

Convex on concave moves joint in opposite directions

Question 14

Congruent

Answer 14

Joint surfaces have maximum contact with each other , tightly compressed
Closes packed

Question 15

C/o.

Facets of spine

Answer 15

C= extension
O= neutral

Question 16

C/o glenohumeral

Answer 16

C= abduction and lateral rotation
O= 55 abd, 30 horizontal add

Question 17

C/o acromioclavicular

Answer 17

C= arm abd 30
O= resting by side

Question 18

C/o ulnohumeral (elbow)

Answer 18

C= extension
O= 70 flx, 10 supination

Question 19

C/o radiohumeral

Answer 19

C= Elbow flx 90, forearm supinated 5
O= full ext, supination

Question 20

C/o proximal radioulnar

Answer 20

C= 5 supination
O= 70 flx, 35 supination

Question 21

C/o radiocarpal ( wrist)

Answer 21

C= ext with ulnar deviation
O= neutral with slight ulnar deviation

Question 22

C/o carpometacarpal

Answer 22

C= none
O= neutral

Question 23

C/o Metacarpophalangeal (fingers)

Answer 23

C= full ext
O= slight flx

Question 24

C/o interphalangeal

Answer 24

C= full ext
O= slight flx

Question 25

C/o hip

Answer 25

C= full ext, med rot
O= 30 flx, 30 abd, slight lat rot

Question 26

C/o knee

Answer 26

C= full ext, lat rot of tibia
O= 25 flx

Question 27

C/o talk rural (ankle)

Answer 27

C= max DF
O= 10 PF

Question 28

Joint play can only happen in

Answer 28

Open packed position

Question 29

Traction / distraction / tension

Answer 29

External force is exerted on joint, causing joint surface to pull apart

Question 30

Compression/ approximation

Answer 30

External force is exerted on joint, causing joint to be pushed together

Question 31

Shear force

Answer 31

Forces occur parallel to the surface

Glide motion

Question 32

Rotary/ torsional force

Answer 32

Twisting motion

Question 33

Is shoulder flx and ext arthrokinematic or osteokinematic motion?

Answer 33

Osteokinematic
