px with extreme motions
when looking at posture, if there is an increased clavicular angle, this could indicate
tight upper trap
when looking at posture, if there is a depressed clavicular angle, suspect

when you observe gross shoulder flexion, look for
• Pain
• 2:1 ratio humeral/scapular rhythm
• Symmetry in glenohumeral creases
- Deeper – not get enough inferior glide humerus
• End with 60⁰ scapular upward rotation
• Winging (with flexion and/or return from flexion)
• Appropriate scapular elevation
• Humeral position at end: medial or lateral rotation
• Minimal movement of spine
when you observe gross lateral rotation of shoulder at 90/90 look for
- Scapula should not adduct during first 35 degrees motion
- Humerus should rotate along vertical axis
- Humeral head should be stable

capsular special tests (or instability tests)
All (apprehensive) Roads (relocation) Lead (load and shift) to Sulcus (sulcus)
explain the apprehension test
they are supine, really you just ER shoulder and watch for apprehension or px
what is relocation test
you do it after the apprehension test
supine, you push the capsule post first, if they report no px or say that feels better…then push the capsule ant and that should cause sx
explain load and shift test
pt is seated
you apply superior load and then push shoulder ant and post
sulcus sign grading scale
1+ = 0.5-1 cm 2+ = 1-2 cm 3+ = 2-3 cm or more 9
list the labrum/articulating surfaces tests
crank clunk quadrant obriens yergasons (crazy carl quietly overcame you)
explain the crank test
they are supine with arm at angle, elbow bent
apply load and fully ER and IR (no ant shift of humeral head)
explain clunk test
supine, elbow at 90 degrees, one hand on post aspect of their capsule, one hand at elbow. Do a slight ant glide (push forward) as you axial load to the body and push the elbow up to face and then full ER.
explain quadrant test
Supine again – 90 degrees, start in ER, do ant glide again,
elbow below head of humerus, axial load and just take forearm to head
explain pos findings for obriens
if pain is reported with resistance in the IR position, but lessens or disappears in the ER position. If superficial joint pain occurs, consider AC joint pathology
explain obriens test
seated slight adduction of shoulder full pronation first and resist then full supination and resist (if px is only felt pronation = pos)
explain yergasons test
yurgonna try to put them in pronation
they are seated, elbow at 90
you are trying to push them into pronation

scapular plane
thumb up and resist
explain lag sign
pt is seated

the superior GHL is under stress in what positions
Under tension with shoulder in adduction, inferior and posterior translation of humerus
the middle GHL is under stress in what positions (and resists what motion)
Under tension with shoulder in ER, resists anterior translation
which lig is the Primary restraint against anterior and posterior dislocations
Inf GHL
list all structures in the suprahumeral space
Long head of biceps tendon Superior joint capsule Supraspinatus Upper margins subscapularis and infraspinatus Subacromial bursa
open packed position GH joint (AKA RESTING)
55 degrees abduction
30 degrees horizontal adduction
Neutral rotation
closed packed GH
ER, ABD
what role does AC joint play in elevation
Must rotate approximately 40-50 degrees for full elevation to occur
If not, elevation limited to ~110 degrees
ac joint and sc joint open packed position
arm at side
the sc joint is really for
stabalization
during arm elevation, the scapula should do what motions
60 degrees upward rotation,
15-25 degrees ER,
15-30 degrees posterior tilt
SC only has a ____ position
open packed (arm at side) does not have closed pack or capsular pattern
biomechanics of 0-90 elevation
Supraspinatus contracts to initiate abduction (depresses and stabilizes head in glenoid fossa)
Remaining rotator cuff muscles contract to pull the humeral head into the glenoid fossa
Around 20-30 degrees, scapular upward rotation begins with concurrent clavicular elevation and axial rotation
At 90 degrees (approx) upper extreme of GH abduction is reached and clavicular elevation ceases due to tension of costoclavicular ligament
At this point scapula has rotated upwardly around 30 degrees
biomechanics of end range elevation (90 - 150)
Scapula upwardly rotates about 60 degrees, with scapular contribution peaking between 90-140 degrees
~ 120 degrees of humeral elevation
~ 75 degrees of GH external rotation needed
Upward rotation accommodated at SC and AC by 30-40 degrees of posterior clavicular axial rotation and clavicular elevation of 30-36 degrees
biomechanics of 150 -180 elevation
Abduction beyond 150 requires adequate motion of upper thorax and cervical spine, while bilateral abduction requires thoracic extension and increase in lumbar lordosis
why is scapular plane ex a good idea
Length-tension relationship of RC muscles is ideal
Movement of the humerus is less limiting because GH capsule is not twisted
Mechanical axis of GH joint is in line with mechanical axis of scapula
Usually see more _____ changes in the tissues surrounding the glenohumeral joint
degenerative
restriction in AROM and PROM is
adhesive capsulitis or frozen shoulder
associative factors of adhesive capsulitis
Female > 40 y/o Trauma Diabetes Prolonged immobilization Thyroid disease Stroke or MI Presence of autoimmune diseases
explain adhesive capsulitis
there is thickening of the tissue, adhesions are made which ends up limiting all motions
what can lead to adhesive capsulitis
arm injuries that end up restricting shoulder motion= adhesions
they end up with synovial inflammation
stages of adhesive capsulitis
Stage 1: Mild signs and symptoms
what motions are lost in stage one of adh cap
Capsular pattern of motion (loss ER and abduction) present, described as achy at rest and sharp at extremes of ROM, pain palpation anterior and posterior capsules, pain radiates to deltoid insertion
what motions are lost at stage 2 adh cap (and sx)
Pain palpation anterior and posterior capsules, pain radiates to deltoid insertion, loss of motion in all planes, pain in all parts of the range
stage 3 adh cap manifests how
Often report painful phase that has resolved but continue to have stiff shoulder, poor scapulohunmeral rhythm during arm elevation, dominance upper trapezius, decreased inferior glide of the GH joint
main feature of stage 4 ad cap
capsular end feel is reached before pt reports px
which phase of healing do you really want to get more aggressive with adh cap
subacute
most unstable direction is ___, this is where most dislocations happen
ant
avulsion of the anterior inferior labrum from the glenoid rim, can lead to instability (lower labrum)

how to differentiate btwn tendonitis and a tear
tendonitis usually improves after 3 weeks
also, tedonitis can achieve full ROM
a clearly pos drop arm test would indicate
possible full thickness tear
a clearly pos supraspinatus test would indicate
partial tear
why is it important to get RC surgery if torn
it can end up limiting the sup space in the capsule as the humerus glides sup
what is primary impingement
intrinsic degenerative process in the structures occupying the subacromial space,
anterior impingement
Intrinsic degenerative process in structures in subacromial space
Typically >40 y/o
Hypomobility may be associated
Occurs when superior aspect of RC is compressed and abraded by surrounding bony and soft tissues
what is secondary impingement
lesser tuberosity of the humerus encroaches on the coracoid process
cause: GH instability or poor control of humeral head in overhead activities, hypermobility may be associated
Have a history of traumatic instability, labrum damage and/or posterior defect humeral head
Alters PICR, humerus migrates too superior
impingment usually causes px with
overhead activity

AC joint sprain 4-6’s they will do
surgery (1 -3 don’t)
with tendonitis you HAVE FULL ROM but it’s just, with a tear you dont have ____
pxful
ROM
if supraspinatus is injured, how does this effect delt
If supraspinatus is injured, the deltoid kicks in – but the movement of humeral head isn’t as efficient…..so when deltoid is dominant the humerus will glide superiorly instead of the supraspinatus controlling the motion from the top, the deltoid tries to control the motion from the bottom.
How will you tell diff btwn primary and secondary impingement –
primary impingement is hypomobile –deg changes
secondary impingement is associated with hypermobility or instability.
