Neer's Test: how to assess subacromial shoulder impingement

Neer's test is probably the quickest shoulder impingement test you can do: in a matter of seconds it gives you a first clue as to whether the subacromial space is "unhappy" when the arm goes up. It's a classic in any painful shoulder assessment, especially for people who do a lot of overhead pressing.

What does this test measure?

Neer's test aims to reproduce mechanical impingement of the structures that pass beneath the acromion (supraspinatus tendon, subacromial bursa, long head of the biceps) by raising the arm into flexion with the humerus internally rotated, compressing them against the anteroinferior edge of the acromion.

Equipment needed

• None

Step-by-step protocol

1. The person stands or sits
2. Position yourself beside or behind them, stabilizing the scapula with one hand to prevent compensation through scapular movement
3. With your other hand, passively raise the person's arm into flexion (in the sagittal plane), with the elbow extended and the humerus internally rotated (palm facing back/down)
4. Bring the arm through the full range of flexion, noting at what point pain appears
5. Repeat on the other side for comparison

Common mistakes

• Failing to stabilize the scapula, allowing the movement to be compensated by scapular tilting and "masking" the impingement
• Moving too fast, not giving the person time to report pain
• Confusing impingement pain with pain from joint stiffness (capsulitis), which usually limits range from the very start of the movement

How to interpret the result

Result	Interpretation
No pain throughout the range	Negative
Pain in the end range of elevation	Positive — suggests subacromial impingement (involving the supraspinatus, subacromial bursa, or long head of biceps)

Neer's test has high sensitivity (roughly above 70-80%) for detecting subacromial impingement, but more limited specificity, since it can also be positive in other shoulder conditions (capsulitis, AC joint pathology). That's why it's worth combining it with other tests to refine your diagnostic suspicion.

It's a screening test, not a diagnosis on its own.

Related tests

Neer's test is often combined with:

• Jobe's test — to specifically assess the strength and integrity of the supraspinatus
• Painful arc — if pain appears in a specific range of abduction, it reinforces the suspicion of subacromial impingement

Why tracking it matters

Pain from subacromial impingement usually responds well to programming adjustments (reducing overhead pressing volume, working on scapular control, improving thoracic mobility), but you need an objective baseline to know whether those adjustments are working. With Movalytics you can log Neer's test result (positive/negative, and at what range of motion the pain appears) at every assessment and compare how it evolves session to session.

Frequently asked questions

Is Neer's test painful for the client? It can cause mild-to-moderate discomfort or pain if there's impingement, but it shouldn't cause intense or lasting pain after the test. Does a positive Neer's test mean there's a rotator cuff tear? Not necessarily. It can simply indicate bursa irritation or tendinopathy without a tear. Imaging is needed to confirm the state of the tissue. Can I apply this test if the client has very limited mobility due to stiffness? Yes, but keep in mind that stiffness (e.g., adhesive capsulitis) can limit movement before reaching the impingement zone, which can produce an unclear result.
