What is the role of the pelvis in the McKenzie Side Glide test?

In the McKenzie Side Glide test, the pelvis is pulled by the examiner to assess the patient's responsiveness to directional movement, specifically in the context of lateral shift or scoliosis. This maneuver finds its clinical application in evaluating patients with back pain and potential disc herniations or radiculopathy. By pulling the pelvis, the examiner aims to create a controlled movement that can help to reveal asymmetries or shifts in the lumbar spine and pelvis, thereby providing insight into the patient's condition.

This technique is crucial for determining how a patient's symptoms may change in response to specific movements and can help guide treatment strategies. The pulling of the pelvis serves to isolate the lumbar spine and assess the role of pelvic position in the patient's overall spinal mechanics, focusing on how the lumbar spine reacts during lateral glide movement. This information is vital for developing effective physical therapy interventions aimed at restoring proper biomechanics and reducing pain.
