Question 1

Why dose scapula rhythm occur

Answer 1

To increase ROM

Congruency

Length-tension relationship

Question 2

Joints involved in the shoulder

Answer 2

Acj
Scj
Ghj
Stj

Question 3

Muscle the control scapula movement

Answer 3

Trapezius, serratus anterior (force couple)

Rhomboids, levator scapula, pecs minor, lat dorsi

Question 4

Joint interaction ratio

Answer 4

2:1

Question 5

JI early phase

Answer 5

Abduct to 90 
GHJ 60
STJ 30 
SCJ 25 
ACJ 5

Question 6

Late phase

Answer 6

GHJ 60
STJ 30
SCJ elevates 5
ACJ upward rotates 25

Question 7

First 30 of abduction

Answer 7

The supraspinatus initiates the movement and movement only come from the ghj

Question 8

At aprox 30 abduction

Answer 8

The upper and lower traps and the upper fibres of the serratus anterior act as a force couple to create upwards rotation of the scapula

Question 9

Because the should girdle is a CK

Answer 9

The upwards rotation continues at the next joint the SCJ this causes the clavicle to elevate to the point of when the costoclevicular ligament gets tight the arm is at 90 now

Question 10

At 90 abduction

Answer 10

The coniod trapezius and costoclavicular ligaments restrain movement. The upper and lower traps and SA continue to rotate the scapula which causes the coracoid process to pull downward

Question 11

Due to the attachment of the conoid and tapazius ligaments onto the clavicle

Answer 11

Rotation of the clavicle occurs an additional 30 of upwards rotation of the scapula is produced by this rotation

Question 12

During this stage

Answer 12

20 of tipping and 40 of winging occurs at the ACJ due the the scapula finding its place on the ribcage

Question 13

The second 90 of abduction

Answer 13

Has come from 60 of ghj movement and 30 of scapula roation at 2:1 overall 180 of abduction is produced fro 120 movement of GHJ and 60 of scapula motion

Question 14

Elbow joint

Answer 14

Humeroulnar joint

Humeroradial joint

Question 15

Forearm joint

Answer 15

Proximal radio ulnar joint

Distal radial ulnar joint

Question 16

Wrist joint

Answer 16

Radio carpal joint

Question 17

Non weight bearing PRUJ

Answer 17

PRUJ - radial head spins within a ring formed by the annular ligament and radial notch of ulnar

Question 18

Weight baring PRUJ

Answer 18

PRUJ Annular ligament and radial notch of ulnar spins around a fixed radial head
