Piriformis syndrome: assessment of current practice and literature review.

Although piriformis syndrome was initially described in 1928, it has remained a nebulous and controversial diagnosis. A literature review reveals that there is no consensus on the diagnosis or treatment of piriformis syndrome. In addition, a survey of 75 physiatrists revealed that whether the diagnosis of piriformis syndrome even exists is controversial. This survey and literature review examines the diagnosis and treatment of piriformis syndrome. The fact that it remains controversial is likely due to a lack of objective clinical trials.
