Manual Therapy/Joint Play

Question 1

Proximal radioulnar joint - arthrokinematics

Answer 1

Convex radial head on the concave radial notch of the ulna

Vex on Cave = opposite

Question 2

How to do an AP to the proximal radioulnar joint

Answer 2

Pt sitting with elbow to 75 flex and 35 supination
PT place hand on radial head and other on ulna
Stabilize ulna and move radius from ant to post

Question 3

How to do a PA to the proximal radioulnar joint

Answer 3

Pt sitting with elbow in 75 flex and 35 supination
PT place hand on radial head and other on ulna
Stabilize ulna and move radius from post to ant

Question 4

Doing an AP to the proximal radioulnar joint will help facilitate what motion

Answer 4

Pronation

It is a posterior glide of the radius

Question 5

Doing a PA to the proximal radioulnar joint will help facilitate what motion

Answer 5

Supination

It is an anterior glide of the radius

Question 6

Arthrokinematics of the distal radioulnar joint

Answer 6

Concave ulnar notch of the radius on the convex ulnar head

Cave on Vex = same

Question 7

How to do an AP to the distal radioulnar joint

Answer 7

Pt elbow flexed to 70-75 and supinated 10
Grasp using thenar on ant bone and fingers on post bone
Stabilize the ulna and move the radius ant to post

Question 8

How to do a PA to the distal radioulnar joint

Answer 8

Pt elbow flexed to 70-75 and supinated 10
Grasp using thenar on ant bone and fingers on post bone
Stabilize ulna and move radius post to ant

Question 9

Doing an AP to the distal radioulnar joint facilitates what motion?

Answer 9

Supination

It is a post glide of the radius

Question 10

Doing a PA to the distal radioulnar joint facilitates what motion

Answer 10

Pronation

It is an ant glide of the radius

Question 11

Humeroradial arthrokinematics

Answer 11

Concave radius on convex capitulum of humerus

Cave on vex = same

Question 12

How to do mobilization to humeroradial joint

Answer 12

Stabilize humerus with table and place hand under humerus to further stabilize
Other hand hold radial shaft/head and push either post or pull ant

Question 13

If you want to gain flexion of the elbow - what mobilization to the humeroradial joint could you do

Answer 13

Ant glide of the radius

PA to the humeroradial joint

Question 14

Humeroulnar joint arthrokinematics

Answer 14

Concave ulna on convex trochlea

Cave on vex = same but there is also rotary component

Question 15

How to do an AP to the humeroulnar joint

Answer 15

Pt supine with elbow flex 75 and 10 supination
PT grasp prox 1/4 ulna
PT apply force on ulna from ant to post and sup

Question 16

How to do a PA to the humeroulnar joint

Answer 16

Pt supine with elbow flex 75 and 10 supination
PT grasp prox 1/4 ulna
PT apply force on ulna from post to ant and inf

Question 17

To facilitate flexion, what type of mobilization would you do to the humeroulnar joint

Answer 17

You want an ant glide
So PA
So ant and inf glide to ulna

Question 18

To facilitate extension, what type of joint mobilization would you do to the humeroulnar joint

Answer 18

You want post glide
So AP
So post and sup glide to ulna
