- Trail 4. Two Hills and a Valley
- Clavicular part:Anteversion, internal rotation, adduction
- Spinal part: retroversion
- Clavicular part:Lateral third of the clavicle
- Spinal part: scapular spine
- Deltoid tuberosity on the humerus
- Locate thespine of the scapula , theacromion and the lat.one-third of the clavicle(Note theV shapethese landmarks form)
- Locate thedeltoid tuberosity
- Palpate between these landmarks to isolate the superficial, convergent fibers of the deltoid.
If pt. alternately abduct and releases, do you feel the fibers contract and relax? 17. Deltoid
- Be sure to explore the deltoids most anterior and posterior aspects.
18. Test for deltoid 19. Test for deltoid
- Fixation:If the scapular fixation muscles are weak, the the examiner must stabilize the scapula
- Test:Shoulder abduction without rotation. When placing the shoulder in test position, the elbow should be flexed to indicate the neutral position of rotation
- Pressure:Against the dorsal surface of the distal end of the humerus.
20. Test for anterior deltoid
- Fixation: If scapular fixation muscles are weak, the scapula must be stabilized by the examiner
- Test: Shoulder abduction in slight flexion, with the humerus in slight lateral rotation.
- Pressure: Against the anteromedial surface of the arm, in the direction of adduction and slight extension
21. Test for posterior deltoid
- Fixation:If scapular fixation muscles are weak, the scapula must be stabilized by the examiner
- Test:Shoulder abduction in slight extension, with the humerus in slight medial rotaion.
- Pressure:Against the posterolateral surface of the arm, above the elbow, in the direction of addduction and slight flexion
