Task 6

Question 1

The student is able to name the diagnostic tests that are appropriate for impingement of the shoulder.

Answer 1

Het cluster of Michener: 
• Hawkins- Kennedy test
• Neer test
• Painfull arc test
• Empty can test (Jobe test)
• External rotation resistance test

Question 2

The student explains the risk factors for developing tendinopathy

Answer 2

• Increase in age
• Sex
• Individual genetic makeup
• Abnormal Kinematics
• Decreased muscle stretch
• Overweight
• Decreased eccentric muscle strength
• Sports, training and surface

Question 3

The student is able to identify the arthrokinematics characteristics of the elbow joint

Answer 3

→ art. humero ulnaris (hinge joint 1 axis)
Ulna = concave. Humerus = convex. Ulna moves (conave) so swing glide
• Flexion: swing slide, ulna translates to ventral
• Extension: swing thou, ulna translates to dorsal
In 70 graden flexie is de tractie richting distaal en dorsaal.

→ art. humero radialis (ball joint with only 2 axes)
Radius = concave. Humerus = convex. Radius (concave) moves so swing glide
• Flexion: swing slide, caput radii is the bowl and translates ventrally
• Extension: swing slide, caput radii is the bowl and translates to dorsal
De tractie is gewoon in het verlengde van de radius.

→ art. radio ulnar proximalis (roll joint 1 axis)
Radius = convex, ulna = concave. Radius moves (convex), so: roll slide
• Supination: roll slide, radius rolls laterally and translates medially
• Pronation: roll slide, radius roll medial and translate lateral

Question 4

The student is able to identify the arthrokinematics characteristics of the wrist joint

Answer 4

→ art. radio ulnar proximalis (roll joint 1 axis)
Radius = convex, ulna = concave.
Radius moves (convex), so: roll slide
• Supination: roll slide, radius rolls laterally and translates medially
• Pronation: roll slide, radius roll medial and translate lateral

→ art. radio ulnar distalis
Radius = concave and ulna is convex. Radius moves (concave) so swing glide
• Supination: swing glide, radius translates to ventrolateral
• Pronation: swing glide, radius translates to ventromedial

→ art. radio carpea (ellipsoid joint / egg joint 2 axes)
Hand = convex. Ulna and radius are concave. Hand moves (convex) so: roll slide
• Palmar flexion: roll slide, head rolls down and translates up
• Dorsal flexion: roll slide, head rolls up and translates down
• Radial abduction: roll slide, head rolls to radial and translates to ulnar
• Ulnar abduction: scroll slide, head rolls ulnar and translates to radial
