Define Osteokinematics
|
observable movemetns of bones in space with the DISTAL end as the reference.
|
|
define SPIN
|
movement around a defined mechanical axis (head of femur, etc)
|
|
define SWING
|
movement in a diagonal or oblique patterns
|
|
two types of SWING. what are they?
|
Pure Swing- straight line. not really functional
Impure Swing- has more of an arc. (legs and arms swinging). Is more functional. |
|
Define Arthrokinematics
|
Unobservable movements between adjacent joint surfaces (roll, glide, and spin)
|
|
when can Roll occur?
|
when the two articulating surfaces are incongruent
|
|
when can Glide occur?
|
when the two articulating surfaces are congruent and flat or congruent and curved.
|
|
Glide only occurs ________ and can be referred to as ________ or ________ glide
|
involuntarily
translation translatory |
|
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 ______
|
gliding
rolling |
|
3 rules to know:
Roll Role Concave rule Convex rule |
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. |
|
how does each end of each phalynx look like?
|
top is convex, bottom is concave
|
|
Joint- distal Interphalangeal
|
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. http://www.pt.ntu.edu.tw/hmchai/SurfaceAnatomy/SUAupper/WristHand.files/HandBones.jpg |
|
Joint- Metacarpophalngeal
|
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 |
|
Joint- Radiocarpal
|
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 |
|
Joint- Radioulnar (proximal)
|
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. |
|
Joint- Radioulnar (distal)
|
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. |
|
Joint- Iliofemoral (this has more spins. Doesn't have a normal roll and glide rule)
|
Concave- acetabalum
Convex- Head of femur Abduction- Superior roll and inferior glide of the femur on the acetabulum. |
|
Joint- Glenohumeral
|
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. |
|
Joint- Tibiofemoral
|
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. http://www.pt.ntu.edu.tw/hmchai/Kinesiology/KINlower/Knee.files/KneeJointMedView.png |
