Osteokinematic and arthrokinematics

Question 1

Name the convex and concave motion for the SC joint

Answer 1

in elevation/ depression:
the clavicle is convex
the sternum is concave.
The roll and glide occur in opposite direction

In protraction/ retraction:
the clavicle is concave
the sternum is convex. The roll and glide occur in same direction (concave on convex same flex)

Question 10

Name the convex and concave motion for the PIP and DIP joints

Answer 10

Convex: proximal phalange
Concave: distal phalange
Motion: same direction
the distal phalange is the moving segment. The distal segment is considered concave, therefore making a concave surface moving on a convex surface, resulting in roll and glide in the same direction.

in which direction does the joint role in respect to the osteokinematic motion?

Answer 24

roll occurs in the same direction as osteokinematic motion

Question 25

what does the convex-concave rule determine?

Answer 25

• Determines the direction of decreased gliding
• which way a joint should be mobilized; which way to force should be applied
• the glide (arthokinematic movement) is based off the rule, the roll is based off oseteopathic movement

Question 26

During shoulder flexion, which way does the humerus roll? which direction is the glide? Which direction should the F be directed for a mob?

Answer 26

Rolls anteriorly
Glides posteriorly
force should be applied in glide direction, posterior for mobilization

Question 27

During shoulder extension , which way does the humerus roll? which direction is the glide? Which direction should the force be directed for a mob?

Answer 27

Rolls posteriorly
Glides anteriorly
Anterior force should be applied for a glide mobilization

Question 28

During shoulder abduction , which way does the humerus head roll? which direction is the glide? Which direction should the force be directed for a mob?

Answer 28

Rolls superiorly
Glides interiorly
Inferior force should be applied for a glide mobilization

Question 29

During shoulder IR , which way does the humerus head roll? which direction is the glide? Which direction should the force be directed for a mob?

Answer 29

Rolls anteriorly

Answer 40

improve flexion: posterior
(tibia moves posteriorly on concave of convex)
-During flexion of the knee also medially/ internally rotates

Improve extension: anterior
During extension the tibia laterally rotates

(concave on convex )

Question 41

improve ER: anterior mob
(Convex and concave head of femer moves posteriorly)

Question 42

Which direction should the patella be mobilized in order to improve knee flexion

Answer 42

The patella glides inferiorly on the femoral tract as it is superiorly buy the quadriceps

• convex on concave therefore oppostie directions
• The patella should be mobilized in fairly to improve knee flexion
• Medial glides are also often used because he patella glides medially and laterally
