The Hawkins-Kennedy test is a common and valuable tool used by healthcare professionals to assess for shoulder impingement. This article will provide a detailed overview of the test, including its purpose, procedure, interpretation, limitations, and relevant considerations for both healthcare professionals and patients.

Understanding Shoulder Impingement

Shoulder impingement, also known as subacromial impingement, occurs when the tendons and bursa surrounding the shoulder joint are compressed. This compression typically happens under the acromion bone, a bony structure forming part of the shoulder blade. The most commonly affected tendons are those of the rotator cuff muscles.

Common causes of shoulder impingement include:

Repetitive overhead movements: Activities like painting, throwing, or weightlifting can lead to overuse and inflammation.
Poor posture: Slouching can narrow the space where the tendons pass, increasing the risk of impingement.
Bone spurs: These bony growths on the acromion can further reduce space, compressing tendons.
Rotator cuff tears: Tears in the rotator cuff muscles can exacerbate impingement symptoms.

The Hawkins-Kennedy Test: Procedure and Interpretation

The Hawkins-Kennedy test is a simple yet effective way to evaluate potential shoulder impingement. Here’s how it's performed:

Procedure:

The patient should be seated or standing.
The examiner passively flexes the patient's shoulder to 90 degrees.
The examiner then internally rotates the patient's shoulder (turns the arm inward) by forcing the patient's arm into their body.
Finally, the examiner extends the patient's elbow.

Interpretation:

A positive Hawkins-Kennedy test is indicated by pain during the maneuver. The pain is typically felt in the anterior (front) shoulder, often radiating to the side of the arm. This pain suggests possible shoulder impingement due to compression of the structures under the acromion. However, it's crucial to remember that a negative test doesn't definitively rule out impingement.

What Causes Pain During the Test?

Pain during the Hawkins-Kennedy test likely stems from compression of the:

Supraspinatus tendon: This is the most commonly affected rotator cuff muscle in impingement.
Subacromial bursa: This fluid-filled sac cushions the rotator cuff tendons.
Long head of the biceps tendon: This tendon runs through the shoulder joint and can also be involved.

Limitations of the Hawkins-Kennedy Test

While the Hawkins-Kennedy test is useful, it's not a definitive diagnostic tool. It has certain limitations:

Subjectivity: The test relies on the patient's report of pain, which can be subjective.
Lack of Specificity: Pain can be caused by other shoulder conditions, making it challenging to pinpoint impingement as the sole cause.
False Positives/Negatives: The test might yield false positives (pain despite no impingement) or false negatives (no pain despite impingement).

Other Tests for Shoulder Impingement

The Hawkins-Kennedy test is often used in conjunction with other clinical tests to arrive at a more comprehensive diagnosis. These may include:

Neer impingement test: This involves passively flexing the shoulder and internally rotating it, similar to the Hawkins-Kennedy test, but without elbow extension.
Empty Can test: This assesses the strength and function of the supraspinatus muscle.
Drop Arm test: This helps identify rotator cuff tears.
Imaging studies: X-rays, MRIs, and ultrasounds can provide a clearer picture of the shoulder joint structures.

Managing Shoulder Impingement

Treatment for shoulder impingement varies depending on the severity of the condition. Options may include:

Rest and ice: Reducing activity and applying ice can help manage inflammation.
Physical therapy: Exercises focusing on strengthening the rotator cuff muscles and improving shoulder range of motion are crucial.
Medication: Over-the-counter pain relievers (NSAIDs) or prescription medications may be necessary.
Corticosteroid injections: These can provide temporary pain relief.
Surgery: In severe cases where conservative treatments fail, surgery may be considered.

Conclusion: The Hawkins-Kennedy Test and Shoulder Pain

The Hawkins-Kennedy test is a valuable tool in evaluating potential shoulder impingement. However, it should be interpreted cautiously alongside a comprehensive clinical examination and, in many cases, imaging studies. If you are experiencing shoulder pain, seeking professional medical attention is critical for accurate diagnosis and effective treatment.
