CRAIG'S

TEST

​• Test positioning

The client is lying prone with the affected leg's knee flexed to 90-degrees.

The therapist stands on the involved side and palpates the greater trochanter.

​• Action

The therapist then passively internally and externally rotates the femur until the greater trochanter is parallel with the examining table.

At this point, the client is asked to hold the hip in this position while the therapist measures the angle between the long axis of the lower leg and the perpendicular axis to the table with a goniometer.

​• Positive finding

If the measured angle is greater than 15-degrees, femoral anteversion is indicated.

If the measured angle is less than 8-degrees, femoral retroversion is indicated.

Increased femoral anteversion leads to toeing-in and squinting patellar.

Femoral retroversion leads to a toeing out position.

Both of these may lead to lower extremity malalignment and subsequent pathologies.

​• Special considerations & comments

A second therapist may be useful to hold the client's hip and leg in the designated position while the first therapist measures the angle.

This test is also known as the Ryder method for measuring femoral anteversion and retroversion.
