Which test involves both compression and distraction techniques?

Gaeslen's test is designed to evaluate the sacroiliac joint's function and can involve both compression and distraction techniques. By applying pressure on one side while stabilizing the other, this test seeks to provoke pain and assess the integrity of the joint.

Compression is achieved by pushing the patient’s knee towards the opposite shoulder, which puts stress on the sacroiliac joint. This maneuver can help identify if the joint is causing discomfort or dysfunction. Conversely, a distraction technique comes into play when the provider assesses the patient's response to movement or easing pressure, which can reveal different characteristics of the pain or dysfunction experienced.

This dual approach of applying force in different directions helps clinicians determine the underlying issues with sacroiliac mechanics, making Gaeslen's test particularly valuable in diagnosing conditions related to that area.
