Chapter 1 kinesiology of the shoulder Flashcards
Osteokinematic Movements
Voluntary movement of our bony levers through their ranges of motion, Take place in one plane
Arthrokinematic Movements
Small, involuntary movements between the articulating joint surfaces, When a joint moves, typically one of the joint surfaces remains stationary as the other moves upon it
3 motions Arthrokinematic Movements
roll slide glide
what movements occur at knee
roll slide glide
If convex surface moves over stationary concave surface, slide occurs in ____direction as movement of bony lever
opposite
If concave surface moves over stationary convex surface, slide occurs in ____ direction as movement of bony lever
same
Closed Packed Joint Position Joint surfaces are _______ _____
maximally congruent
Closed Packed Joint Position Surrounding ligaments and joint capsule are ____ in this position
taut
Closed Packed Joint Position This is the position for greatest _______ ____ ___
stability of the joint
Open Packed Joint Position Joint surfaces are relatively ______ ___ ____ in relation to one another
free to move
Open Packed Joint Position Joint surfaces are __________ in relation to one another
relatively free to move
Open Packed Joint Position ___ and ____as well as joint play occur here
AROM and PROM
GH open kinetic chain convex moves on concave in opposite direction closed kinetic chain _____ moves on fixed ______ moves in the ____ direction
concavity, convexity, same
open kinetic chain and closed kinetic chain are _______ rules
opposite
Capsular Pattern- Typical pattern of limitation in a joint’s movement if the capsule is the structure ______ ___ _____
