Articular Movement # 3

Front 1

Osteokinematics

Back 1

Observable movements of bones in space with the distal end as the reference

Front 2

Anatomical bone movement (spin)

Back 2

pure bony rotational movement occurring around a defined mechanical axis (ex. head of femur, humerus and radius)

Front 3

Physiological bone movement (swing)

Back 3

any multiplanar bony movement in a diagonal or oblique pattern

Front 4

Pure swing

Back 4

cardinal plane movement (movement not simultaneous with a spin), not really functional

Front 5

Impure swing

Back 5

arcuate movement (rotation or spin is simultaneous with movement) i.e. diagonal or PNF movement ex. hand making arc while walking

Front 6

Arthrokinematics

Back 6

unobservable artciular movements between adjacent joint surfaces (roll, glide and spin)

Front 7

Roll

Back 7

new points on one surface come into contact with new points on the opposing surface (like a tire rolling on the ground

Front 8

Glide

Back 8

translatory motion in which one constant point on one surface is contacting new points on the other surface
* pure gliding can occur when two surfaces are congruent and flat or congruent and curved
* glide only occurs involuntarily and can be referred to as translation or translatory glide

Front 9

3 major arthrokinematic rules

Back 9

1. roll rule- roll always occurs in the direction of bone movement (ant/post or sup/inf)
2. concave rule- roll and glide occur in the same direction
3. Convex rule: roll and glide occur in opposite direction

Front 10

Steps to establish arthrokinematics

Back 10

1. what bone doing most of the movement?
2. What direction is movement? roll full
3. Is bone doing movement convex or concave? concave/convex rule

Front 11

Interphalangeal joint- arthrokinematics: proximal/ distal flexion extension

Back 11

Proximal- convex Distal - concave
flexion- anterior roll anterior glide of distal phalanx on middle phalanx
extension- posterior roll, posterior glide of distal phalanx on middle phalanx

Front 12

Metacarpophalangeal joint- arthrokinematics

Back 12

Proximal- convex Distal- concave
flexion- anterior roll, anterior glide of proximal phalanx on metacarpal
extension- posterior roll, posterior glide of proximal phalanx on metacarpal

Front 13

Radiocarpal joint- arthrokinematics

Back 13

Concave- radius convex- carpals
flexion- anterior roll, posterior glide of carpals on radius
extension- posterior roll, anterior glide of carpls on radius

Front 14

ulnar deviation- arthrokinematics

Back 14

medial roll, lateral glide of radius on ulna

Front 15

radial deviation- arthrokinematics

Back 15

lateral roll, medial glide of radius on ulna

Front 16

Radioulnar (proximal) arhtrokinematics

Back 16

concave- ulna convex radius
pronation- anterior roll posterior glide of radius on ulna
supination- posterior roll anterior glide of radius on ulna

Front 17

radioulnar (distal)- arthrokinematics

Back 17

concave- radius convex- ulna
pronation- anterior roll, anterior glide of radius on ulna
supination- posterior roll posterior glide of radius on ulna

Front 18

tibiofemoral- arthrokinematics

Back 18

concave- tibia convex- femur
flexion- posterior roll posterior glide of tibia on femur
extension- anterior roll anterior glide of tibia on femur

Front 19

talotibial- arthrokinematics

Back 19

concave- tibia convex- talus
plantarflexion- posterior roll anterior glide of talus on tibia
dorsiflexion- anterior roll, posterior glide of talus on tibia

Front 20

what happens the more congruent a joint is?

Back 20

the more spin occurs

Front 21

elbow arthrokinematics during pull up on way up

Back 21

concave- ulna convex- humerus (flexion)
anterior roll posterior glide of humerus on ulna

Front 22

Push up- arthrokinematics- movement on way up at wrist

Back 22

concave- radius convex- carpals
extension- posterior roll posterior glide of radius on carpals
