Question 5

Elbow Flexion

Answer 5

o 0 to 145 degrees
o supine, upper limb parallel to lateral midline of trunk and forearm in
anatomical position
o Axis: over lateral epicondyle of humerus
o Stationary Arm: lateral midline of the humerus in line with the acromion
process
o Moving Arm: lateral midline of the radius in line with the styloid process
o Stabilization: the distal end of the humerus is stabilized.

Question 6

Elbow Extension

Answer 6

o From 145 to 0 degrees (not any hyperextension)

supinated
o Goniometric alignment and stabilization same as elbow flexion.
o Place towel under distal humerus to keep glenoid fossa and elbow in line

o Stabilization: stabilize the opposite shoulder

Question 9

Subscap MMT

Answer 9

o AG: prone, shoulder abducted and flexed over edge of table
o GM: prone, shoulder flexed over edge of table

o Resistance: applied proximal to wrist on anterior surface of forearm
o Stabilization: stabilize humerus and thorax with your hand and forearm

Question 10

Pec Major (both heads) MMT

Answer 10

AG: supine with shoulder abducted and elbow flexed 90 degrees
o GM: sitting, abducted 90 degrees, elbow flexed 90 degrees, upper limb is
supported
o Sternal head: horizontal adduction and extension from 90 degrees of
abduction, moving towards opposite shoulder in diagonal direction, punch
down
o Clavicular head: horizontal adduction with flexion from 90 degrees of
abduction, punch up
o Resistance: applied to anteromedial arm above elbow
o Stabilization: contralateral shoulder or ipsilateral trunk.

Question 11

Lat Dorsi MMT

Answer 11

o AG: prone, shoulder flexed and medially rotated over edge of table
o GM: sidelying, upper limb supported, in 90 degrees of shoulder flexion and
medial rotation and with elbow flexed
o Patient extends the shoulder, allowing elbow to flex
o Resistance: applied to posterior arm just proximal to elbow
o Stabilization: thorax

Question 12

Infra/ Teres Minor

Answer 12

AG: prone with elbow flexed over edge of table (slightly abducted and rested
on towel – elbow breaks at corner of table)
o GM: prone with shoulder flexed over edge of table
o Patient laterally rotates arm 90 degrees
o Resistance: applied proximal to wrist on extensor surface of forearm
o Stabilization: humerus and thorax
