3- Osteokinematics/ Arthrokinematics

Front 1

Define Osteokinematics

Back 1

observable movemetns of bones in space with the DISTAL end as the reference.

Front 2

define SPIN

Back 2

movement around a defined mechanical axis (head of femur, etc)

Front 3

define SWING

Back 3

movement in a diagonal or oblique patterns

Front 4

two types of SWING. what are they?

Back 4

Pure Swing- straight line. not really functional

Impure Swing- has more of an arc. (legs and arms swinging). Is more functional.

Front 5

Define Arthrokinematics

Back 5

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

Front 6

when can Roll occur?

Back 6

when the two articulating surfaces are incongruent

Front 7

when can Glide occur?

Back 7

when the two articulating surfaces are congruent and flat or congruent and curved.

Front 8

Glide only occurs ________ and can be referred to as ________ or ________ glide

Back 8

involuntarily
translation
translatory

Front 9

Rolling and gliding usually surface simultaneously but no necessarily in proportion to one another. The more congruent the articulation- the more the _______; the more the Incongruent the articulation- the more the ______

Back 9

gliding
rolling

Front 10

3 rules to know:

Roll Role
Concave rule
Convex rule

Back 10

roll rule- roll always occurs in the direction of bone movement ( ant./post. or sup/inf)

Concave rule- in relationship to the CONCAVE surface, roll and glide occur in the SAME direction (will be mostly glide)

Convex rule- in relationship to the CONVEX surface, roll and glide occur in the OPPOSITE directino.

Front 11

how does each end of each phalynx look like?

Back 11

top is convex, bottom is concave

Front 12

Joint- distal Interphalangeal

Back 12

concave- distal phalnyx
convex- middle phalynx

flexion- anterior roll and anterior glide of the distal on the middle phalynx.

Extension- Posterior roll and posterior glide of the distal phangeal on the middle.

Front 13

Joint- Metacarpophalngeal

Back 13

Concave- proximal phalynx
Convex- Metacarpal

flexion- Anterior roll and anterior glide of the proximal phanageal on the metacarpals

Extension- Posterior roll and posterior glide of the proximal phangeal on the metacarpal

Front 14

Joint- Radiocarpal

Back 14

Concave- radius
Convex- carpals

Flexion- Anterior roll and Posterior Glide of the carpals on the radius

Extension- posterior roll and Anterior glide of the carpals on the radius

Front 15

Joint- Radioulnar (proximal)

Back 15

Concave- ulna
Convex- radius

Pronation (anterior movement)- anterior roll and posterior glide of the radius on the ulna.

Supination (posterior movement)- posterior roll and anterior glide of the radius on the ulna.

Front 16

Joint- Radioulnar (distal)

Back 16

Concave- radius
Convex- ulna

Pronation- anterior roll and anterior glide of the radius on the ulna

Supination- Posterior roll and posterior glide of the radius on the ulna.

Front 17

Joint- Iliofemoral (this has more spins. Doesn't have a normal roll and glide rule)

Back 17

Concave- acetabalum
Convex- Head of femur

Abduction- Superior roll and inferior glide of the femur on the acetabulum.

Front 18

Joint- Glenohumeral

Back 18

Concave- glenoid
Convex- head of humerus

Flexion- Posterior roll and anterior glide of the humerus on the glenoid.

Extension- Anterior rolland posterior glide of the humerus on the glenoid.

Abduction- Superior roll and inferior glide of the humerus on the glenoid.

Front 19

Joint- Tibiofemoral

Back 19

Concave- Tibia
Convex- Femur

Flexion- posterior roll and posterior glide of the tibia on the femur.

Extension- anterior roll and anterior glide of the tibia on the femur.

Front 20

Joint- Talotibial

Back 20

Concave- tibia
Convex- talus

Plantarflexion- posterior roll and anterior glide of the talus and the tibia.

Dorsiflexion- Anterior roll and posterior glide of the talus on the tibia.

Anterior roll and Anterior glide of the tibia on the talus.

Front 22

During a pull-up on the way up, what's occurring at the elbow joint (humeroulnar)?

Back 22

(refer everything back to anatomical!!)

Concave- Ulna
Convex- Humerus

Anterior roll and posterior glide of the humerus on the ulna
