Someone shared this article with me, and I wanted to pass it along. Itís on the topic of, like the subject says, piriformis syndrome. Itís a dense read to anyone without some exposure to anatomy and medical language, and there are terms that went over my head. But, I found it interesting.
The piriformis is a deep muscle of the gluteal region. The origin of its name, according to my texts, is Ďpear-shaped.í Iíve had a running hypothesis that many people who self-diagnose themselves with sciatica may actually be having some issues with their piriformis, or maybe even this actual condition. Much like the pectoralis minor with the nerves of the brachial plexus (topic for another time), the piriformis can affect the sciatic nerve.
Itís been my experience that tension and knots in the piriformis can have a strong effect on walking, and pain in the low back. One of its actions is lateral rotation of the hip jointĖthat is, turning the hip and leg out. Ballet dancers standing in first position are engaging both piriformises to stand heels together and toes turned out.
From an Eastern perspective, I can imagine that change in posture impinging the urinary bladder and gallbladder meridians down the back and sides of the lower body, respectively, and perhaps overstretching the stomach, spleen, kidney, and liver meridians where they run up and down the legs. If memory serves, the UB meridian has at least one point that coincides with the piriformisís muscle belly.
