Shoulder Tests: The Complete Guide to Assessing Pain, Instability and the Rotator Cuff

The shoulder is the most mobile joint in the body, and that comes at a price: it's also one of the most commonly injured, especially in people who train overhead presses, throwing sports, or who simply spend many hours with their shoulders rounded forward in front of a screen.

The good news is that there's a well-established battery of orthopedic tests that lets you, in just a few minutes, get a pretty solid idea of which structure might be involved: the rotator cuff, the capsule and ligaments (instability), the labrum, the long head of the biceps, or the subacromial space.

In this guide we've put together the 14 most searched-for and most useful shoulder tests for your initial assessment, organized around what really matters: which structure or pathology each one points to.

Why do a specific shoulder assessment?

A well-applied battery of shoulder tests gives you:

1. A working hypothesis about which structure might be involved in the pain or limitation
2. Objective criteria for referring to a specialist when imaging or medical treatment is needed
3. A measurable starting point for designing the program (what to temporarily avoid, what to strengthen, what to mobilize) and for tracking progress

No single test is diagnostic on its own. The value lies in combining several tests and looking at the overall pattern, not a single isolated result.

The 14 shoulder tests, organized by what they assess

Rotator cuff (tendon strength and integrity)

Test	When to use it
Jobe Test (empty can)	Suspected supraspinatus involvement — pain or weakness when raising the arm in the plane of the scapula with internal rotation
Drop Arm Test	Suspected rotator cuff tear (supraspinatus/infraspinatus) — inability to hold the arm raised, with a sudden, uncontrolled drop
Lift-Off Test (Gerber)	Suspected subscapularis involvement — weakness or pain with internal rotation, hand behind the back
IRRST (Internal Rotation Resistance Strength Test)	Differentiating internal (posterosuperior) impingement from external impingement, especially in throwing sports

Subacromial impingement

Test	When to use it
Neer Test	First quick screen for subacromial impingement — pain when raising the arm in flexion with internal rotation
Hawkins-Kennedy Test	Complements Neer from a different angle (90° flexion + internal rotation) — if both are positive, it reinforces suspicion of impingement
Painful Arc Test	Identify at which range of abduction the pain appears, helping locate the affected structure (subacromial vs. acromioclavicular)

Biceps and labrum

Test	When to use it
Yergason Test	Suspected long head of biceps tendinopathy or tendon instability in the bicipital groove
Speed's Test	Another test for the long head of the biceps, useful as a complement or alternative to Yergason
O'Brien Test (SLAP)	Suspected labral injury (SLAP) — deep joint pain with the arm in adduction, flexion and internal rotation

Glenohumeral instability

Test	When to use it
Apprehension Test	Suspected anterior shoulder instability — the person resists or shows apprehension during abduction + external rotation
Relocation Test	Confirms or rules out the apprehension test finding by applying posterior counter-pressure
Sulcus Sign	Suspected inferior/multidirectional instability — a visible "sulcus" appears under the acromion when pulling the arm downward

Motor control and scapula

Test	When to use it
Shoulder Motor Control Test (scapular dyskinesis)	Assess the quality of scapular movement during arm elevation, regardless of whether there's pain

How to choose the right test for your context

• No pain, want a preventive/general assessment → start with the shoulder motor control test and, if everything looks clean, you don't need to dig further for now.
• Pain when raising the arm or doing overhead presses → combine Neer + Hawkins-Kennedy + painful arc to narrow down subacromial impingement.
• Suspected rotator cuff weakness or tear (night pain, functional weakness) → Jobe (supraspinatus), drop arm (tear) and Lift-Off (subscapularis).
• Overhead/throwing athlete with "odd" pain and no clear impingement → add the IRRST to rule out internal impingement.
• Pain at the front of the shoulder, around the biceps → Yergason and/or Speed's.
• "Deep" joint pain, clicking, history of trauma → O'Brien for the labrum.
• Sensation of the shoulder "slipping out," instability, history of dislocation → apprehension + relocation + sulcus.

In practice, you'll almost never use just one test: the typical approach is to start with general screening (impingement + motor control) and, based on what you find, add more specific tests to confirm or rule out hypotheses.

From assessment to tracking

Running the battery of tests is only the first step. What really makes a difference is being able to compare how a client's shoulder evolves over the weeks: is the impingement that was positive two months ago now negative? Has subscapularis strength improved?

With Movalytics you can log each of these tests at every assessment, save the results (positive/negative, ranges, strength), and see the evolution automatically in charts, without having to dig through old spreadsheets.

Frequently Asked Questions

How many shoulder tests should I run in a first assessment? You don't need all 14. Start with 2-3 general screening tests (impingement + scapular motor control) and, based on the findings and the symptoms the client reports, add more specific tests. Do these tests diagnose shoulder injuries? No. They're orthopedic screening tests: they guide clinical suspicion and help decide whether to refer for medical imaging (ultrasound, MRI), but they don't replace a diagnosis. What if several tests come back positive at the same time? That's quite common, because many shoulder structures are interrelated (sustained subacromial impingement can lead to secondary rotator cuff weakness, for example). In that case, the overall pattern is more informative than any single test, and reinforces the case for referral if there's doubt. Can I use these tests on anyone, even without pain? Yes. In asymptomatic people they're useful as a preventive assessment, especially in throwing sports or training with a high volume of overhead pressing, to catch motor control issues before they cause pain. How often should I repeat this battery of tests? If there's an active process (pain, rehab), every 2-4 weeks to track the trend. For a preventive assessment with no findings, every 2-3 months is usually enough.
