Muscles Involved:[edit | edit source]
Pectoralis Major
Patient Positioning[edit | edit source]
- Supine with elbow flexed to 90 degrees & shoulder abducted to either 90, 60 or 120 degrees depending on desired fibres to be tested.
Joint start Position[edit | edit source]
GENERAL SCREENING TEST
- shoulder abduction to 90 degrees
CLAVICULAR HEAD - C5 + C6 nerve root innervation, superior 1/3 of muscle fibres
- shoulder abduction to 60°
STERNAL HEAD - C7, C8 + T1 nerve root innervation, inferior 2/3 of muscle fibres
- shoulder abduction to 120°
Therapist Position[edit | edit source]
- Therapist is standing at test side
To Test[edit | edit source]
- Patient actively horizontally adducts the shoulder through full available range.
- The difference between this test as a general screen or specifically for clavicular or sternal head will be direction of movement against resistance
GENERAL SCREENING - starting at 90 degrees abduction, arm horizontally across chest CLAVICULAR HEAD - starting from 60 degrees abduction, arm will move up and across chest STERNAL HEAD - starting from 120 degrees abduction, arm will move down and across chest
- For grades 4 to 5 apply resistance to forearm, just proximal to wrist in a direction opposite to horizontal adduction
