to perform the Seated Piriformis Stretch Test for Deep Gluteal syndrome Get our very own Assessment Ebook and Mobile App! Links are in the video description. Hi and welcome back to Physiotutors Deep Gluteal Syndrome, abbreviated as DGS, is defined as pain in the buttock area caused from a non-discogenic entrapment of
the sciatic nerve in the subgluteal space. The 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 lesion. For this reason the term “Deep Gluteal Syndrome” instead of “Piriformis Syndrome” is now preferred. Commonly 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 excacerbated 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. According to a study done by Martin et al. in the year 2013 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 Before you conduct the test make sure you have examined and excluded more prevalent pathologies in
the lumbar spine and SI joint that could explain the patient’s symptoms. To
perform the test have the patient in sitting position over the edge of the
examination table with the hip flexed to approximately 90
degrees and the knee extended. While palpating the sciatic notch, the examiner adducts and internally rotates the limb. The 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. The test
is positive, if the patient’s familiar complaints of gluteal pain and/or
paresthesia radiating into the posterior aspect of the lower extremity are
reproduced. Alright, this was our video on the Seated Piriformis Stretch test. If

  1. is there any benefit over a SLR-like piriformis testing, which from the joint angles is exactly the same?

  2. I have pain in outer side of the thigh while doing such as clam shell exercise.
    Without stretching, the pain sometimes can be also in the gluteal area.
    What is possible name of the situation?
    Thanks @Physiotutors
