What is a Sharp Purser Test?

The atlanto-axial joint is a crucial joint in the neck that connects the skull to the first two vertebrae of the spine. It comprises two articulations: one between the atlas and axis (C1 and C2) vertebrae and another between the dens of the axis and anterior arch of the atlas.

The atlanto-axial joint allows movement in the neck, from side to side and up and down. Without it, the neck would be very stiff and uncomfortable. It also plays a vital role in stabilizing the head on the spine during activities such as running, jumping, or other vigorous movements. However, its location at the top of the spine makes it vulnerable to injury. Damage to this joint could lead to significant pain and reduced mobility in the neck.

A healthcare professional may use a to evaluate for any possible damage to the atlanto-axial joint. This test involves palpating the posterior aspect of the axis or the second cervical vertebra below the skull's base.

The patient may feel a slight snapping sensation or "clunking" in the joint if there is any damage. Further tests, such as X-rays or MRI scans, may be necessary to diagnose abnormalities accurately.

Sharp Purser Test Interpretation

The Sharp Purser Test is a valuable tool to assess the atlanto-axial joint's range of motion and stability. The test can help screen various neck injuries and provide valuable information for diagnosis.

A positive result on the Sharp Purser Test can suggest the joint is unstable, hypermobile, or a ligamentous injury could present. Further imaging or tests should be ordered if these results are indicated.

While the Sharp Purser Test can help diagnose neck injuries, it should not be used in isolation. The results of this test must be interpreted in the context of other physical tests, the patient's history, and any imaging studies.

When to use this Sharp Purser Assessment?

The Sharp Purser Test is a useful screening tool for neck pain and can help diagnose injuries in the upper cervical spine. It assesses range of motion at the lower cervical spine and the strength of muscles across the front and back of the neck. You may conduct this test to:

Identify any areas of tightness or weakness in the neck muscles

The Sharp Purser Test can help determine whether a patient has neck pain due to musculoskeletal issues or another underlying medical condition. It can also be used as an indicator of the effectiveness of treatment.

Test the patient’s range of motion

This assessment allows you to measure a patient’s range of motion in their neck, which can provide insight into any underlying medical issues.

Check for reflexes

You can use the Sharp Purser Test to check for any reflexes in the patient’s neck that may indicate a medical condition. This is important as nerve-related issues must be treated differently than musculoskeletal issues.

Evaluate neck symmetry

You can use the Sharp Purser Test to compare the patient's range of motion between both sides of the neck. This will allow you to see if any asymmetry indicates an underlying medical issue.
