Arthrokinematics

Question 1

Movement of one bone on another. Flexion, extension, abduction etc. Under voluntary control

Answer 1

Osteokinematic motion

Question 2

Occurs when muscles contract to move the joint

Answer 2

Active range of motion

Question 3

Occurs when someone or something else moves a joint through range of motion

Answer 3

Passive range of motion

Question 4

The type of resistance that a clinician feels when bringing a patient’s joint to the end of it passive range of motion, then applying slight overpressure

Answer 4

End feel

Question 5

Full passive range of motion at a joint and motion limited by an expected anatomical structure

Answer 5

Normal end feel

Question 6

May be present with pain, guarding, swelling, abnormal anatomy. What to see if you can find the ”tissue at fault”

Answer 6

Abnormal end feel

Question 7

Muscle bulk being compressed

Answer 7

Soft normal end feel

Question 8

Tension from surrounding ligaments, capsule or muscles. Firm stop with slight. Most common type of end feel

Answer 8

Firm normal end feel

Question 9

Bone contacts bone at end of passive range of motion. Hard and abrupt limit to passive range of motion

Answer 9

Hard normal end feel

Question 10

Elbow flexion create a _____ normal end feel.

Answer 10

Soft

Question 11

Elbow extension creates a ______ normal end feel.

Answer 11

Hard

Question 12

Knee flexion creates a ______ normal end feel.

Answer 12

Soft

Question 13

Forearm supination creates a ______ normal end feel.

Answer 13

Firm

Question 14

Ankle dorsiflexion and plantarflexion creates a ______ normal end feel.

Answer 14

Firm

Question 15

Shoulder medial and lateral rotation creates a _______ normal end feel.

Answer 15

Firm

Question 16

Types of abnormal end feels

Answer 16

Boggy end feel
Muscle spasm
Empty end feel
Springy block

Question 17

Soft tissue edema present. Wet sponge feel

Answer 17

Boggy end feel

Question 18

Protective reaction to injury

Answer 18

Muscle spasm

Question 19

So much pain is present, clinician can’t get to end of ROM

Answer 19

Empty end feel

Question 20

Rebound movement at end of ROM. Internal damage to joint

Answer 20

Springy block

Question 21

The manner in which adjoining joint surface move on each other during osteokinematic joint movement

Answer 21

Arthrokinematic Motion

Question 22

Small arthrokinematic motions that accompany active osteokinematic motions. Do not happen independent of osteokinematic motion. Not under voluntary control

Answer 22

Component movements

Question 23

Arthrokinematic motion that happens between joint surfaces when an external force creates passive motion at a joint. Ex.) roll, glide, spin

Answer 23

Joint play

Question 24

Technique that applies external force to generate a passive oscillatory motion or sustained stretch between joint surfaces. CAN BE USED TO RESTORE ROM OR DECREASED PAIN. Manipulation

Answer 24

Joint mobilization

Question 25

Cause joint distraction. Joint surfaces pull away from each other
Ex.) carrying a heavy suitcase will cause distraction

Answer 25

Traction forces

Question 26

Cause joint approximation. Joint surfaces are pushed together
Ex.) doing a push up will cause approximation in the UEs

Answer 26

Compression forces

Question 27

Cause a gliding motion. Joint surfaces move parallel to each other. Assist in restoring joint mobility

Answer 27

Shearing forces

Question 28

Other than vertical force is applied and results in compresssion on the concave side and distraction on convex side

Answer 28

Bending

Question 29

One force turning one end around longitudinal axis and another force is fixed or turning opposite direction

Answer 29

Rotary

Question 30

Type of motion occurring at a joint depends on the shape of the joint surfaces. Most joints have one convex and one concave

Answer 30

Joint surface shape

Question 31

two bones forming a convex-concave relationship. Most synovial joints. One home end typically larger than the other

Answer 31

Ovoid joint

Question 32

Each joint surface is convex one direction and concave the other. Carpometacarpal (CMC joint of thumb)

Answer 32

Sellar/saddle shaped joint

Question 33

Three potential motions at the joint surface

Answer 33

Roll
Spin
Glide

Question 34

Rolling of one joint surface on another. New points on each surface come into contact through the motion

Answer 34

Roll

Question 35

Linear movement of a joint surface parallel to the plane of the adjoining joint. One point contacts new points as it moves

Answer 35

Glide(slide)

Question 36

Rotation of the moveable joint surface on the fixed adjacent surface

Answer 36

Spin
