GAENSLEN'S

TEST

​• Test positioning

The client lies on the side of the uninvolved leg (lower leg). With the involved leg (upper leg) in slight hyperextension, the client then flexes the knee of the uninvolved side toward the chest.

​• Action

The therapist stabilizes the client's pelvis and further extends the client's involved leg.

​• Positive finding

Pain in the sacroiliac region is considered a positive finding and may be associated with sacroiliac joint dysfunction.

​• Special considerations & comments

The client may report pain in the hip or anterior thigh region.

This may be related to hip joint pathology, anterior thigh musculature tension, or L4 nerve root tension.

This test can be performed with the client in a supine position, however, the therapist should be cautious of a false negative test due to the inability of obtaining enough involved leg hip extension.

Gaenslen's Test, named after Dr. Frederick Gaenslen, was developed through his work in diagnosing sacroiliac joint pathology.

Contributions from Dr. James Cyriax have further refined its application in the assessment of lumbar and sacral spine involvement.
