Hip internal rotation in prone applying stretch to the piriformis and deep hip external rotators and compressing the sciatic nerve in the deep gluteal space. You can also try a variation of this test where the patient resists further internal rotation, adding an isometric external rotation force. A positive test for deep gluteal syndrome is reproduction of the patient’s familiar buttock pain and or referred sciatic nerve symptoms.

A positive test for deep gluteal syndrome is reproduction of the patient’s familiar buttock pain and or referred sciatic nerve symptoms.

Hip flexion, adduction and internal rotation in sidelying, to apply stretch to the deep hip external rotators and compressing the sciatic nerve in the deep gluteal space. You can also try a variation of this test where the patient resists further internal rotation, adding an isometric external rotation force. A positive test for deep gluteal syndrome is reproduction of the patient’s familiar buttock pain and or referred sciatic nerve symptoms.
