Seated Piriformis Stretch Test | Piriformis Syndrome | Deep Gluteal Syndrome Hip<\/h2>\nDeep gluteal syndrome, abbreviated as DGS is defined as pain in the buttock area caused by a non-discogenic entrapment of the sciatic nerve in the subgluteal space.<\/span>\n\nThe structures that can be involved in sciatic nerve entrapment are not only the piriformis but also fibrous bands containing blood vessels, gluteal muscles, hamstring muscles, the gemelli-obturator internus complex, vascular abnormalities and space-occupying lesions. <\/span>For this reason, the term \u201cdeep gluteal syndrome\u201d instead of \u201cpirformis syndrome\u201d is now preferred.<\/span>\n\nCommonly reported symptoms include hip or buttock pain and tenderness in the gluteal and retro-trochanteric region. The pain is often described to be sciatica-like, often unilateral and exacerbated with rotation of the hip in flexion and knee extension. Other symptoms include intolerance of sitting for more than 20 to 30 minutes, limping, disturbed or loss of sensation in the affected extremity and pain at night getting better during the day.<\/span>\n\nAccording to a study done by Martin et al. (2013)<\/a>, the seated piriformis stretch test had a sensitivity of 52% and a specificity of 90% in the diagnosis of endoscopically confirmed sciatic nerve entrapment. This is the only study evaluating this test yet, which is why we give this test a moderate clinical value to confirm the condition in practice.<\/span>\n

While palpating the sciatic notch, the examiner adducts and internally rotates the limb.<\/span>\n\nThe seated piriformis stretch test is thought to lengthen the deep rotators of the hip joint and create dural tension of the sciatic nerve in an effort to elicit familiar pain.<\/span>The test is positive if the patient\u2019s familiar complaints of gluteal\u00a0<\/span>pain and\/or paraesthesia radiating into the posterior aspect\u00a0<\/span>of the lower extremity are reproduced.<\/span>\n\nOther common tests to assess for deep gluteal syndrome are:\n
