Abstract
Having isolated a test with prima facie relevance to entrapment of the sciatic nerve by the piriformis muscle, we review the success of treatment focused on that pathogenetic mechanism. The FAIR test’s sensitivity and specificity are calibrated. We then investigate whether the functional test is a better predictor of successful treatment than positive signs and symptoms. Some further support for the functional test’s utility may be seen in the correlation between the amount of delay seen in the FAIR test and patients’ clinical improvement on the VAS.

In patients with previous lumbar laminectomy, a lumbosacral corset during PT may reduce the tendency toward hyperlordosis in these patients. It is a safety measure after fusion, scoliosis surgery, and disc replacement as well.
