In the McKenzie Side Glide test, the examiner's action involves pulling what part of the patient's body?

The McKenzie Side Glide test is specifically designed to evaluate a patient's response to lateral movements of the spine, particularly in the context of assessing the impact of lumbar or thoracic disc modifications. During this test, the examiner applies a lateral force to the patient's pelvis while stabilizing the upper body.

By pulling on the pelvis, the examiner observes how the patient's spine responds to this lateral glide. This action is crucial for identifying any asymmetrical movement patterns or discomfort that might suggest the involvement of intervertebral discs, especially in conditions like herniated discs or sciatica. The test helps clinicians determine the direction in which the patient prefers to move, which can inform treatment strategies.

Understanding the mechanics of movement in the pelvis relative to the torso and legs is essential in clinical practice. The focus on the pelvis allows for assessment of the lumbar spine and its alignment, making it the key target in this particular test.
