PIRIFORMIS SYNDROME • Sciatica like pain caused by compression of the sciatic nerve by the piriformis muscle, which extends from the pelvic surface of the sacrum to the upper border of the greater trochanter of the femur and, during running or sitting, can squeeze the sciatic nerve at the site where the nerve emerges from under the piriformis to over the gemellus and obturator internus muscles.

9. Chief Complaint • Patient states that moist heat over low back and hip area decreases the pain. • Cold (including weather) increases his pain. • Standing and sitting for prolonged periods increase the pain.

10. Physical Exam • Abnormal Thoracolumbar ROM • Flexion 75 degrees with pain in right low back (norm 90 deg.). • Extension 45 degrees with pain (norm 35 deg.). • Right lateral flexion 35 degrees (norm 40 deg.). • Right rotation 28 degrees (norm 35 deg.).

11. Physical Exam • Positive/Clinically Relevant Orthopedic Tests • Supported Adam’s Test (dec pain with support) • SLR on Right at 8 degrees (pain decreases with external rotation of the hip) • Braggard’s • Patrick Fabere (dec sciatic symptoms) • SOTO decrease pain

12. Physical Exam • Postural Analysis • Left head tilt • Left high shoulder • Left high hip • External rotation of right foot

13. Physical Exam • Palpation • Restriction throughout spine • Hypertonicity in lumbar musculature • Trigger points in belly of Piriformis Muscle

14. X-ray Findings • Mild left curvature involving the T9-L5 levels • Lateral lumbar reveals a uniform reduction of the posterior body height of L5 (probable congenital variation in anatomical presentation of L5 body).

15. DDX: • Sciatica • Piriformis Syndrome • Disc Herniation

16. Diagnosis: • Condition: Piriformis Syndrome (pseudosciatica) • Secondary to: Sacroiliac segmental dysfunction • With associated: myospasm

17. Treatment • CMT 3 x / week for 2 weeks • CMT 2 x / week for 3 weeks • Then Re-evaluate • Adjunctive procedures were performed as listed PRN • Myofascial release of piriformis, TFL, and QL muscles • PIR stretch of piriformis and psoas muscles

18. Treatment • Adjunctive procedures (cont.) • Percussor (lower extremities) • Aqua massage • Treatment Goals: • Decrease trigger points, spasm and pain • Increase ROM

19. Treatment • Nutrition • Calcium / Magnesium complex • Increase Water intake Home stretches were given for piriformis and psoas muscles to be performed bid
