75. Glenohumeral Joint: Biomechanics
Static shoulder stabilisation
- requires very little muscle support
- provided by trapezius and supraspinatus
- vertical stability:glenoid facing up by trapezius
- inferior stability: intra articular pressure and
adhesion/cohesion of articular surfaces
- anatomic curvature of humerus
- glenoid labrum
- negative intraarticular pressure
76. Glenohumeral Joint: Biomechanics
Dynamic shoulder stabilisation
- requires complex factors
Major dynamic stabilisers
- long head of triceps and biceps
- humeral head max stabilisation: subscapularis
Posterior restraints
- <90° abduction : post capsule
- 90° abduction : IGHLC
77. Scapulohumeral Rhythm
Describes the movement relationship between the
scapula and humerus to maintain angle b/w scapula
and humerus <30°
First 30° of shoulder joint motion pure GH motion
After that, for every 2° of shoulder flexion or abduction,
the scapula rotates 1°
2:1 ratio → scapulohumeral rhythm
Full abduction: glenoid completely support humerus

95. Pain
Typically pain of gleno-humeral origin is
felt in the upper arm, often at the insertion
of the deltoid.
Severe shoulder problems can cause pain
to radiate as far as the radial side of the
wrist.
Impingement/rotator cuff
pathology:anterior/lateral shoulder pain
aggrevated with overhead activities
96.
97. Pain
The shoulder is derived from the fifth
cervical segment and therefore refers pain
into the C5 dermatome.
The acromio-clavicular joint is a C4
structure and refers pain into the C4
dermatome.
98. Pain
The shoulder is deep and proximal in the
C5 dermatome, hence it can potentially
refer pain a great distance.
Conversely the acromio-clavicular joint is a
superficial structure at the distal end of the
dermatome causing it to give rise to
accurate, local pain

117. IMPINGEMENT:
Primary impingment Secondary impingment
Occur because of degenerative
changes to the rotator cuff,the
acromian process,the coracoid
process and anterior tissues from
stress overload.
Occurs due to problem with
muscle dynamics with an upset
in the normal force couple action
leading to muscle imbalance and
abnormal movement patterns at
both the glenohumeral joint and
the scapulothoracic articulation.
Impingement is primary cause of
pain.
It is secondary to altered muscle
dynamics.
Occurs mostly in 40+ age group
people.
Occurs in young patients.(15-
35years old)
It is said to be intrinsic when
rotator cuff degeneration occurs
and extrinsic when the shape of
the acromian and degeneration of
the coracoacromial ligament
occurs.
Commonly seen with joint
instability.
118. NEER IMPINGMENT TEST:
PATIENT’S AFFECTED ARM IS PASSIVELY AND
FORCIBLY FULLY ELEVATED IN THE SCAPULAR
PLANE WITH THE ARM MEDIALLY ROTATED BY THE
EXAMINER.
•This passive stress
causes “jamming of
the greater tuberosity
against the
anteroinferior border
of the acromian.
•The patient’s face
shows pain reflecting
a +ve test.
119. HAWKIN’S KENNEDY IMPINGMENT
TEST:
PATIENT STANDS / SITS WHILE THE EXAMINER FORWARD
FLEXS THE ARM TO 90º AND FORCIBLY MEDIALLY ROTATES
THE SHOULDER.
•This movement
pushes the
supraspinatus
tendon against the
anterior surface of
the coracoacromial
ligament and
coracoid process.
•Pain indicates +ve
test.
120. THIS TEST MAY BE PERFORMED WITH THE PATIENT
STANDING OR SEATED.WITH THE ELBOW EXTENDED,
THE PATIENT’S ARM IS HELD AT 90° OF
ABDUCTION,30° OF HORIZONTAL FLEXION, AND IN
INTERNAL ROTATION (WITH THUMB FACING DOWN).
THE EXAMINER EXERTS PRESSURE ON THE UPPER
ARM DURING THE ABDUCTION AND HORIZONTAL
FLEXION MOTION.
•When this test elicits severe
pain and the patient is
unable to hold his or her arm
abducted 90° against gravity,
this is called a positive empty
can test/supraspinatus
tendinitis.
•The superior portions of the
rotator cuff (supraspinatus) are
particularly assessed in
internal rotation (with the
thumb down), and the
•anterior portions in external
rotation.
121. DROP ARM(CODMAN’S)TEST:
THE PATIENT IS SEATED, AND THE EXAMINER
PASSIVELY ABDUCTS THE PATIENT’S EXTENDED ARM
APPROXIMATELY 120°. THE PATIENT IS ASKED TO
HOLD THE ARM IN THIS POSITION WITHOUT SUPPORT
AND THEN SLOWLY ALLOW IT TO DROP.
Weakness in maintaining the
position of the arm, with or
without pain, or sudden dropping of
the arm suggests a rotator cuff
lesion. Most often this is due to a
defect in the supraspinatus.
122. APLEY’S SCRTCH TEST:
THE SEATED PATIENT IS ASKED TO TOUCH THE
CONTRALATERAL SUPERIOR MEDIAL CORNER OF THE
SCAPULA WITH THE INDEX FINGER.
Pain elicited in the rotator cuff and failure
to reach the scapula because of restricted
mobility in external rotation and abduction
indicate rotator cuff pathology (most
probably involving the supraspinatus).
123. YOCUM TEST
LIFT PATIENT’S ELBOW TO SHOULDER
HEIGHT WITH ARM RESTING ON THE
NORMAL SHOULDER
124. HORNBLOWER’S SIGN (PATTE TEST)
determines the strength of
the teres minor.
The examiner elevates the
patient’s arm to 90 degrees
in the scapular plane. The
therapist then flexes the
elbow to 90 degrees, and the
patient is asked to laterally
rotate the shoulder. A
positive test occurs with
weakness and/or pain.
125. SUBSCAPULARIS TEST/LIFT OFF
TEST:
PATIENT IN STANDING POSITION PLACES THE
DORSUM OF THE HAND ON THE BACK. THE PATIENT
THEN LIFTS THE HAND AWAY FROM THE BACK. IF
PATIENT IS ABLE TO DO THEN LOAD PUSHING ON
HAND IS DONE BY THE EXAMINER TO CHECK THE
STRENGH.
•A patient with a subscapularis
tear will be unable to do
this.
•Abnormal motion in the scapula
during the test may indicate
scapular instability.
126. COMPARATIVE TESTING OF BOTH SIDES IS BEST.
THE PATIENT’S ARMS SHOULD HANG RELAXED WITH
THE ELBOWS FLEXED 90° BUT NOT QUITE TOUCHING
THE TRUNK. THE EXAMINER PLACES HIS OR HER
PALMS ON THE DORSUM OF EACH OF THE PATIENT’S
HANDS AND THEN ASKS THE PATIENT TO
EXTERNALLY ROTATE BOTH FOREARMS AGAINST
THE RESISTANCE OF THE EXAMINER’S HANDS.
Pain or weakness in external rotation
indicates a disorder of the
infraspinatus (external rotator).
.
127. SPRING BACK TEST:Infraspinatus
Patient either in sitting or standing hold the
elbow in flexion at 90º by the side. Examiner
passively bring the shoulder to 90º abduction and
laterally rotate to the end range and ask the
patient to hold the arm to this position. For +ve
test of infraspinatus weakness/lesion patient
cannot hold the position and hand spring back
anteriorly.
128. TERES MAJOR TEST:
THE PATIENT IS STANDING AND RELAXED. THE
EXAMINER ASSESSES THE POSITION OF THE
PATIENT’S HANDS FROM BEHIND. THE TERES MAJOR
IS AN INTERNAL ROTATOR. WHERE A CONTRACTURE
IS PRESENT, THE PALM OF THE AFFECTED HAND
WILL FACE BACKWARD COMPARED WITH THE
CONTRALATERAL HAND.
129. LABRAL TEARS
Clunk test
Crank Test
O Brien’s Test
Compression-rotation test akin to Apley’s
grinding
Biceps load test
130. CLUNK TEST
Patient supine, examiner
puts hand on the posterior
aspect of the shoulder,
other hand hold the
humerus above the elbow
and abducts the arm over
the head. Then pushing
anteriorly with the hand
under the shoulder and
rotating the humerus
laterally with the other
hand, feel for a grind or
clunk which may indicate
a tear of the labrum.
131. O’BRIEN’S TEST
Labral, AC, or biceps

Arm flexed to 90°
Arm cross-arm
adducted 10-15°
Elbow extended
Max pronation

132. LABRAL TEAR: CRANK TEST
Abduct arm to 90-120°
Stabilize shoulder
Elbow secured with
one hand
Axially load with ER /
IR at shoulder
Positive test: audible
or painful click / catch /
grind
134. PAINFUL ARC:
THE PATIENT’S ARM IS PASSIVELY AND ACTIVELY
ABDUCTED FROM THE REST POSITION ALONGSIDE
THE TRUNK. PAIN IN THE ACROMIOCLAVICULAR
JOINT OCCURS BETWEEN 140°AND 180° OF
ABDUCTION. IN AN IMPINGEMENT SYNDROME OR A
ROTATOR CUFF TEAR, BY COMPARISON, PAIN
SYMPTOMS WILL OCCUR BETWEEN 70°AND 120°.
In the evaluation of the active
and passive ranges of motion,
the patient can often avoid the
painful arc by externally
rotating the arm while
abducting it. This increases
the clearance between the
acromion and the diseased
tendinous portion of the
rotator cuff, avoiding
impingement in the range
between 70° and 120°.
135. THE NORMAL SIDE.
FORCED ADDUCTION TEST ON
HANGING ARM:
THE EXAMINER GRASPS THE UPPER ARM OF THE AFFECTED
SIDE
WITH ONE HAND WHILE THE OTHER HAND RESTS ON THE
CONTRALATERAL SHOULDER AND IMMOBILIZES THE
SHOULDER GIRDLE. THEN THE EXAMINER FORCIBLY
ADDUCTS THE HANGING AFFECTED ARM BEHIND THE
PATIENT’S BACK AGAINST THE PATIENT’S RESISTANCE.
Pain across the
anterior aspect of the
shoulder suggests
acromioclavicular joint
disease or subacromial
impingement.
136. DUGA’S TEST:
THE PATIENT IS SEATED OR STANDING AND
TOUCHES THE CONTRALATERAL SHOULDER
WITH THE HAND OF THE 90°-FLEXED ARM OF
THE AFFECTED SIDE THEN ATTEMPT TO LOWER
THE ELBOW TO THE CHEST IS MADE.
Acromioclavicular joint pain
suggests joint disease
(osteoarthritis,
instability, disk injury, or
infection).
A differential diagnosis
must exclude anterior
subacromial impingement
137. BICEP TENDON TEST
THE CLOSE ANATOMIC PROXIMITY OF
THE INTRAARTICULAR PORTION OF THE
TENDON TO THE CORACOACROMIAL
ARCH PREDISPOSES IT TO INVOLVEMENT
IN DEGENERATIVE PROCESSES IN THE
SUBACROMIAL SPACE. A ROTATOR CUFF
TEAR IS OFTEN ACCOMPANIED BY A
RUPTURE OR INJURIES OF THE BICEPS
TENDON.
138. SPEED TEST:
IN SITTING THE EXAMINER RESISTS SHOULDER
FORWARD FLEXION BY THE PATIENT WHILE THE
PATIENT’S FOREARM IS IN SUPINATION. PAIN IN
THE REGION OF THE BICIPITAL GROOVE
SUGGESTS A DISORDER OF THE LONG HEAD OF
THE BICEPS TENDON.
139. YERGASON TEST:
WITH THE PATIENT’S ELBOW FLEXED TO 90º AND
STABILIZED AGAINST THORAX AND WITH FOREARM
PRONATED, THE EXAMINER RESISTS SUPINATION
WHILE THE PATIENT ALSO LATERALLY ROTATES THE
ARM AGAINST RESISTANCE. DURING THIS
MOVEMENT WHEN THE TENDON IS FELT IN GROOVE
AS “POP OUT” .
•Pain in the bicipital groove is a sign
of a lesion of the biceps tendon, its
tendon sheath, or its ligamentous
connection via the
•transverse ligament.
•The typical provoked pain can be
increased by pressing on the tendon in
the bicipital groove.
140. BICEP TENDINITIS WITH
TRANSVERSE HUMERAL LIGAMENT
TEST:
THE PATIENT IS SEATED WITH THE ARM ABDUCTED
90°, INTERNALLY ROTATED, AND EXTENDED AT THE
ELBOW. FROM THIS POSITION, THE EXAMINER
EXTERNALLY ROTATES THE ARM WHILE PALPATING
THE BICIPITAL GROOVE TO VERIFY WHETHER THE
TENDON SNAPS.
•In the presence of
ligamentous insufficiency,
this motion will cause the
biceps tendon to
spontaneously displace out of
the bicipital groove.
•Pain reported without
displacement suggests biceps
•tendinitis.
141. INSTABILITY TESTS
SHOULDER PAIN MAY BE ATTRIBUTABLE
TO AN UNSTABLE SHOULDER. USUALLY
HISTORY OF A PERIOD OF INTENSIVE
SHOULDER USE (SUCH AS COMPETITIVE
SPORTS), AN EPISODE OF REPEATED
MINOR TRAUMA (OVERHEAD USE), OR
GENERALIZED LIGAMENT LAXITY. BOTH
YOUNG ATHLETES AND INACTIVE
PERSONS ARE AFFECTED, MEN AND
WOMEN ALIKE.
142. ANTERIOR APPREHENSION TEST:
PATIENT LIE SUPINE OR IN SITTING . ARM IS
ABDUCTED TO 90º WITH OTHER HAND ON THE
HUMERAL HEAD AND LATERALLY ROTATED
SLOWLY BY THE EXAMINER. WHILE
PERFORMING PATIENT’S EXPRESSIONS ARE
NOTED FOR APPREHENSION/FURTHER
RESISTENCE TO ROTATION. . WITH THE GUIDING
HAND, THE EXAMINER PRESSES THE HUMERAL
HEAD IN AN ANTERIOR AND INFERIOR
DIRECTION
Shoulder pain with reflexive
muscle tensing is a sign of an
anterior instability syndrome.
This muscle tension is an
attempt by the patient to prevent
imminent subluxation or
dislocation of the humeral
head.
143. SURPRISE TEST
Similar to apprehension test
But at max ext rotation the posterior force on the
humerus is removed and we look for
apprehension
Most accurate single test for anterior instability
144. ROCKWOOD TEST
It is important to know that at 45° of abduction,
the test primarily evaluates the medial
glenohumeral ligament and the subscapularis
tendon. At or above 90° of abduction, the
stabilizing effect of the subscapularis is
neutralized and the test primarily evaluates the
inferior glenohumeral ligament.
145. POSTERIOR APPREHENSION TEST:
PATIENT LIES SUPINE OR IN SITTING POSITION AND
EXAMINER ABDUCTS ARM IN SCAPULAR PLNE TO 90º
WHILE STABILIZING THE SCAPULA WITH OTHER
HAND. EXAMINER THEN APPLIES A POSTERIOR
FORCE ON THE ELBOW AND MOVES THE ARM IN
ADDUCTION AND MEDIALLY ROTATION.
146. ANTERIOR AND POSTERIOR DRAWER
TEST:
THE PATIENT IS SEATED. THE EXAMINER STANDS
BEHIND THE PATIENT. TO EVALUATE THE RIGHT
SHOULDER, THE EXAMINER GRASPS THE PATIENT’S
SHOULDER WITH THE LEFT HAND TO STABILIZE THE
CLAVICLE AND SUPERIOR MARGIN OF THE SCAPULA
WHILE USING THE RIGHT HAND TO MOVE THE
HUMERAL HEAD ANTERIORLY AND POSTERIORLY.
147. INFERIOR APPREHENSION
TEST/FEAGIN TEST:
PATIENT STANDS WITH THE ARM ABDUCTED TO 90º
AND ELBOW EXTENDED AND RESTING ON TOP OF
THE EXAMINER’S SHOULDER. EXAMINER CLASP
HIS/HER HANDS AROUND THE PATIENT’S HUMERUS
AND PUSHES THE HUMERUS DOWN AND FORWARD.
IN THIS SULCUS MAY ALSO BE SEEN ABOVE THE
CORACOID PROCESS.
148. SULCUS TEST:
PATIENT STANDS WITH ARM BY THE SIDE AND
SHOULDER MUSCLE RELAXED. THE EXAMINER
GRASPS THE PATIENT’S FOREARM BELOW THE
ELBOW AND PULLS THE ARM DISTALLY. THE
PRESENCE OF SULCUS/INDENTATION INFERIOR
TO ACROMIAN IS THE INDICATIVE.
