What signifies a positive result in the McKenzie Side Glide test?

In the McKenzie Side Glide test, a positive result is indicated by the reproduction of symptoms on the affected side. This test is primarily utilized to evaluate lateral mechanical issues in the spine and how those issues influence pain activation and movement. When the symptoms return or are provoked during the glide towards the affected side, it suggests that there is likely a mechanical influence on the patient's symptoms related to the lumbar spine.

Reproducing symptoms during the test assists clinicians in understanding the directionality of the patient's condition and whether movement toward that side exacerbates or relieves the pain. This information is critical in developing an effective treatment plan, focusing on addressing the patient's specific mechanical issue.

Other outcomes like improved mobility, decreased pain, or increased flexibility do not directly define a positive McKenzie Side Glide test result, as they do not specifically indicate the relationship between movement and symptom reproduction, which is central to this assessment’s objective.
