The Load and Shift Test assesses anterior and posterior translation of the glenohumeral joint. This article explains the protocol, interpretation, limitations and how it fits into shoulder instability assessment.
Shoulder instability presentations may include:
anterior apprehension or instability sensations
posterior shoulder discomfort or slipping sensations
history of subluxation or dislocation
pain during loading or overhead movement
The Load and Shift Test is a clinical assessment used to evaluate passive anterior and posterior translation of the humeral head relative to the glenoid.
It is commonly used alongside:
Apprehension Test
Relocation Test
Shoulder ROM assessment
Rotator cuff strength testing
Patient history of instability
A positive finding may indicate increased joint laxity or instability tendencies, but it does not independently diagnose structural instability.
Primary purpose: Assess anterior and posterior glenohumeral translation
Body region: Shoulder
Commonly associated with: Shoulder instability or laxity
Positive finding: Excessive translation or asymmetry compared to contralateral side
Negative finding: Symmetrical, controlled translation
Clinical role: Supports shoulder instability assessment reasoning
Best interpreted with: Apprehension and relocation testing
The Load and Shift Test is a passive assessment where the examiner applies an anterior or posterior force to the humeral head while stabilising the scapula to assess glenohumeral translation.
The test is intended to:
assess capsular laxity
evaluate joint translation
identify asymmetry between sides
support shoulder instability assessment clusters
The Load and Shift Test may help:
assess anterior shoulder instability tendencies
evaluate posterior shoulder laxity
compare side-to-side translation
support instability classification
guide return-to-load decisions
It may be particularly relevant in:
contact athletes
overhead athletes
individuals with instability history
post-dislocation rehabilitation contexts
hypermobility presentations
The test evaluates:
anterior glenohumeral translation
posterior glenohumeral translation
capsular laxity
joint stability under passive load
A positive finding may suggest increased laxity or instability tendency, but does not confirm structural labral injury.
The Load and Shift Test may be useful for:
exercise professionals
sports performance settings
allied health assessment environments
shoulder instability screening
rehabilitation professionals
movement assessment education
Consider using the Load and Shift Test when a client reports:
shoulder instability sensations
history of subluxation or dislocation
apprehension during overhead activity
shoulder “slipping” or “shifting”
recurrent shoulder discomfort in loaded positions
The test becomes more meaningful when combined with:
Apprehension Test
Relocation Test
patient instability history
rotator cuff strength assessment
Use caution when:
acute dislocation is suspected
severe pain or guarding is present
recent surgery has occurred
fracture is suspected
neurological symptoms are present
Stop testing if:
pain increases significantly
apprehension becomes severe
guarding prevents safe assessment
Examination plinth or stable surface
Open space for safe shoulder handling
Client sits or lies supine depending on examiner preference.
Shoulder relaxed at side
Arm slightly abducted (~20–30°) for anterior/posterior assessment
One hand stabilises scapula
Other hand grasps humeral head
Stabilising hand on scapula (posterior aspect)
Testing hand on proximal humerus
Apply gentle axial load into the glenoid (“seating” the humeral head).
Translate humeral head anteriorly and posteriorly.
Assess amount of movement and end-feel.
Compare side-to-side differences.
Ask the client to:
report discomfort or apprehension
describe instability sensations
remain relaxed during passive movement
A positive Load and Shift Test may involve:
excessive anterior or posterior translation
asymmetry compared to opposite side
reproduction of instability symptoms
soft or poorly defined end-feel
A negative finding involves:
symmetrical translation
firm end-feel
no instability symptoms
Stop if:
pain increases significantly
apprehension becomes severe
client requests cessation
Use gentle graded force
Avoid aggressive anterior translation in suspected instability
Always compare with contralateral side
A positive test may increase suspicion of:
shoulder instability tendencies
capsular laxity
anterior or posterior joint hypermobility
It becomes more meaningful when combined with:
positive apprehension test
history of subluxation or dislocation
functional instability during sport
However, it does not:
confirm labral tear
diagnose instability severity independently
determine surgical necessity
Translation may also be influenced by:
general joint laxity
training history
muscle control deficits
A negative test may suggest:
controlled glenohumeral translation
reduced likelihood of gross instability
However:
micro-instability may still exist
symptoms may occur only in sport-specific positions
further testing may still be required
High-quality diagnostic accuracy data for the Load and Shift Test is limited and variable.
Available evidence suggests:
shoulder instability tests often show variable sensitivity and specificity depending on population and criteria
no single test reliably identifies instability on its own
clusters of instability tests improve diagnostic reasoning
At the time of writing:
consistent, high-quality pooled sensitivity, specificity and likelihood ratio values for the Load and Shift Test alone are not well established
This means:
the test should be used as part of a broader instability assessment
it should not be used in isolation for decision-making
interpretation must include history, symptoms and functional findings
Inter-rater reliability improves with standardised positioning
Examiner experience significantly influences translation grading
Patient relaxation affects results
Validity considerations:
glenohumeral translation does not always correlate directly with symptoms
structural laxity and symptomatic instability are not always aligned
functional instability requires broader assessment than passive translation alone
Common errors:
excessive force application
poor scapular stabilisation
inconsistent grading of translation
not comparing sides
Limitations:
subjective grading system
variability between examiners
limited standalone diagnostic value
The Load and Shift Test may help:
assess shoulder laxity tendencies
support instability classification
guide rehabilitation progression
monitor changes in joint control
assist return-to-sport planning
Best used alongside:
Apprehension Test
Relocation Test
rotator cuff strength testing
functional stability testing

It assesses anterior and posterior translation of the shoulder joint.
No. It may indicate laxity but does not confirm instability as a diagnosis.
Excessive or asymmetrical humeral head translation compared to the opposite side.
No. It is most useful in combination with other instability tests.
No. Translation and symptom response are both considered.
Load and Shift assesses glenohumeral translation
Positive findings suggest laxity or instability tendency
It does not confirm labral or structural pathology
Best used in a cluster of shoulder instability tests
