Shoulder Special Tests for Impingement: Guide & Comparison

Shoulder special tests for impingement are used to investigate shoulder pain during reaching, lifting, and overhead movement. Clinicians commonly use the Neer test, Hawkins–Kennedy test, and painful arc test, together with rotator cuff strength assessment and a thorough history. These findings help assess subacromial pain syndrome or rotator cuff-related shoulder pain, but a positive test does not prove that one structure is mechanically “pinched.”

This guide compares the most useful procedures, explains how to interpret a positive result, and links to detailed descriptions of individual tests already available on Special Tests & Examination.

Quick comparison: shoulder impingement special tests

Clinical note: These tests probe related but different features of shoulder function. None is a standalone test that conclusively diagnoses or excludes shoulder impingement, a specific tendon tear, or bursitis.

What does “shoulder impingement” mean?

The phrase shoulder impingement syndrome has historically described pain thought to arise when subacromial tissues are compressed during arm elevation. In modern practice, subacromial pain syndrome and rotator cuff-related shoulder pain are often preferred because symptoms can reflect a combination of tendon loading, pain sensitivity, strength, movement patterns, and other factors—not necessarily one fixed anatomical obstruction.

Common symptoms include pain over the lateral shoulder or upper arm, discomfort while reaching overhead or behind the back, and pain when sleeping on the affected side. The symptom pattern overlaps with other conditions, including rotator cuff tears, glenohumeral osteoarthritis, adhesive capsulitis, acromioclavicular joint pain, and referred pain from the cervical spine.

Before special testing: a complete shoulder examination

1. History: ask about trauma, gradual onset, occupation, overhead sport, night pain, symptoms below the elbow, weakness, and loss of function.
2. Observation: note posture, visible deformity, muscle wasting, guarding, and quality of scapular movement.
3. Active range of motion: check elevation, abduction, external rotation, and functional internal rotation, documenting pain location and restrictions.
4. Passive range of motion: assess whether restriction is similar to active movement. Marked loss of passive external rotation suggests that a capsular or joint disorder may need consideration.
5. Strength and symptom response: compare external rotation, abduction, and other relevant movements with the opposite side.
6. Targeted special tests: choose a small number based on the working differential diagnosis rather than performing every test routinely.

See our complete shoulder examination guide and shoulder range of motion overview for complementary assessment.

1. Neer impingement test

The Neer test is a passive pain-provocation maneuver used to investigate subacromial-related shoulder pain.

1. Ask the patient to sit or stand comfortably and relax the shoulder.
2. Stabilize the scapula to reduce compensatory movement.
3. With the arm internally rotated as tolerated, gently elevate the arm forward toward the available end range.
4. Ask whether the maneuver reproduces the patient’s familiar shoulder pain, and document its location.

Positive result: reproduction of characteristic anterior or lateral shoulder pain during elevation may support the clinical suspicion of subacromial pain, but it is not specific to a particular tissue. Avoid forceful end-range elevation or interpreting vague discomfort as proof of pathology. For detailed technique, see the Neer test article.

2. Hawkins–Kennedy test

The Hawkins–Kennedy test is widely used alongside the Neer and painful arc tests.

1. Position the shoulder in approximately 90° of forward flexion and the elbow in 90° of flexion.
2. Support the arm and gently move the shoulder into internal rotation without forcing the range.
3. Ask whether the movement reproduces familiar anterolateral shoulder pain.

Positive result: familiar shoulder pain during internal rotation can contribute to a rotator cuff-related pain assessment. Pain may also arise from other shoulder structures, and restricted motion can affect the response. Read the Hawkins–Kennedy test guide.

3. Painful arc test

Unlike the two passive provocative tests, the painful arc test observes symptoms during an everyday active movement.

1. Ask the patient to slowly lift the arm sideways from the resting position toward overhead.
2. Have the patient lower the arm in a controlled manner.
3. Record the angle or portion of the movement that produces the usual shoulder pain, as well as whether symptoms lessen above that zone.

Positive result: pain most pronounced during approximately 60°–120° of abduction is classically called a painful arc. The pattern supports a subacromial or rotator cuff-related presentation but is not diagnostic by itself.

The 2025 rotator cuff tendinopathy clinical practice guideline identifies the painful arc and Hawkins–Kennedy tests as potentially useful components of assessment, while emphasizing that even these tests provide only modest diagnostic information.

4. Empty can (Jobe) and full can tests

These maneuvers assess symptoms and strength during supraspinatus-related loading, not “impingement” in isolation.

Empty can test

Raise the arms to approximately 90° in the scapular plane, with thumbs directed downward. Apply gentle downward resistance while the patient maintains position. Compare pain and strength on both sides. View the Jobe / empty can test.

Full can test

Repeat resistance testing with the thumbs directed upward in the scapular plane. Document whether familiar pain is reproduced and whether there is true weakness rather than movement limited by pain or poor effort.

Interpretation: pain may indicate sensitivity to rotator cuff loading, while pronounced weakness—particularly after trauma—raises a different concern and may justify further evaluation for a significant tear.

5. Resisted external rotation and additional cuff tests

With the elbow near the trunk at about 90° flexion, ask the patient to rotate the forearm outward against controlled resistance. Document pain, weakness, and side-to-side differences. When a substantial tear is suspected, further testing such as the external rotation lag sign or drop arm test may be appropriate. A painful positive impingement maneuver does not establish a full-thickness tendon tear.

6. Scapular assistance test

During arm elevation, a clinician can gently assist scapular upward rotation and posterior tilt. If familiar symptoms decrease or available elevation improves, scapular movement may be a modifiable contributor to symptoms. The test is best used to guide further examination or rehabilitation hypotheses, not to independently establish a diagnosis. See our scapular assistance test guide.

Which shoulder impingement test is most accurate?

There is no single “best” test that reliably confirms shoulder impingement in every patient. The 2025 clinical practice guideline for rotator cuff tendinopathy notes modest diagnostic value overall: the painful arc test may add some support when positive, while a negative Hawkins–Kennedy test can reduce suspicion, but likelihood ratios are small. A 2024 systematic review also found variable sensitivity and specificity across Neer, Hawkins–Kennedy, painful arc, and other tests. Different patient populations, definitions of the target disorder, and reference standards limit direct comparison.

For clinical reasoning, combine the mechanism and symptom history with active and passive motion, strength, familiar-pain reproduction, and relevant tests for alternative diagnoses. Do not simply count positive findings and treat them as a definitive anatomical diagnosis.

Important differential diagnoses and red flags

• Possible major rotator cuff tear: sudden traumatic pain with new, pronounced loss of active elevation or marked weakness warrants prompt assessment; the drop arm and lag tests may add useful information.
• Adhesive capsulitis: substantial restriction of passive shoulder motion, especially external rotation, suggests a different clinical presentation.
• Acromioclavicular joint pain: localized pain near the AC joint and symptoms with cross-body adduction suggest targeted AC joint evaluation.
• Cervical referral or neurological conditions: neck-related symptoms, paresthesia, or objective neurological deficits require a broader examination.
• Urgent concerns: major trauma, deformity, suspected dislocation, fever with a hot joint, new significant neurological deficits, or chest pain with referred shoulder pain require urgent assessment as appropriate.

Practical shoulder examination checklist

1. Establish whether symptoms were traumatic or non-traumatic and identify the patient’s main functional limitations.
2. Measure active and passive range of motion; compare with the other shoulder.
3. Check resisted abduction and external rotation; note pain versus objective weakness.
4. Choose painful arc, Hawkins–Kennedy, or Neer testing to assess the familiar pain response.
5. Use additional cuff, AC joint, instability, or cervical tests only when clinically indicated.
6. Document the working diagnosis, uncertainty, need for imaging or referral, and functional baseline for reassessment.

Frequently asked questions

What are the three main special tests for shoulder impingement?

Neer, Hawkins–Kennedy, and painful arc are commonly used to assess subacromial or rotator cuff-related pain. They should be interpreted alongside history, mobility, and strength testing.

What is the difference between Neer and Hawkins–Kennedy tests?

The Neer test provokes symptoms through passive arm elevation, while Hawkins–Kennedy uses passive internal rotation with the arm held at about 90° of flexion.

Does a positive Hawkins–Kennedy test prove impingement?

No. It reproduces pain under a particular load or movement and cannot identify a single damaged tendon, bursa, or structural mechanism by itself.

Is shoulder impingement the same as a rotator cuff tear?

No. Rotator cuff-related pain may occur with or without a tear; a major tendon tear involves a different question about tissue integrity and strength. The clinical findings and need for imaging differ.

When is imaging considered?

Imaging decisions depend on trauma, significant weakness, suspected serious pathology, persistent symptoms despite appropriate care, and whether imaging is likely to change management. Routine imaging is not required for every painful shoulder.

Key takeaways

Neer, Hawkins–Kennedy, and the painful arc are useful components of a shoulder impingement assessment—not definitive diagnoses. Add strength testing, passive mobility, functional limitations, and a differential diagnosis before drawing conclusions.
