Q

Scapular Motion Testing

Downward Rotation

Upward Rotation

Scapulo-Humeral Rhythm

A

Turning on A/P axis so scapula rotates in frontal plane to tilt glenoid fossa downward

Turning on A/P axis so scapula rotates in frontal plane to tilt glenoid fossa upward

1:2 Ratio of scapular motion to humeral motion (180 degrees abduction = 60 scapular + 120 humeral)

Q

Scapular Motion Testing:

Elevation

Depression

Abduction (Protraction)

Adduction (Retraction)

Backward Tilt

Forward Tilt

A

Superior glide in vertical direction along Coronal Plane

Inferior glide in vertical direction along Coronal Plane

Away from spine, combined with lateral tilt around thorax

Moving closer to the spine

Turning on horizontal axis so posterior surface faces downward and inferior angle is anterior

Turning on horizontal axis so posterior surface faces upward and inferior angle protrudes

SC Abduction

SC Adduction

SC Flexion

SC Extension

A

Scapular Elevation leads to Inferior movement of SC joint

Shoulder Depression leads to Superior motion of SC joint

Protraction of scapula leads to Posterior glide of clavicle at SC joint

Retraction of scapula leads to Anterior glide of clavicle at SC joint
