Cluster of Laslett

The Cluster of Laslett assesses sacroiliac joint (SIJ) dysfunction by using four provocation tests to reproduce pain and determine if the SIJ is the source. These tests apply controlled stress to the joint to evaluate pain response. A positive result in at least two tests suggests SIJ involvement.

At least two positive test results indicate SIJ involvement. If the first two tests are negative, additional tests should be performed to confirm the diagnosis. A combination of clinical evaluation and further diagnostic testing may also be necessary.

Pelvic tilts are one of the best exercises for sacroiliac pain as they help stabilize the SIJ, improve mobility, and reduce discomfort. Strengthening exercises for the core and glute muscles, such as bridges and bird dogs, can also support SIJ function. Gentle stretching of the hip flexors and lower back may also further relieve tension.
