Piriformis syndrome is a condition which is believed to result from nerve compression at the sciatic nerve by the piriformis muscle. [2] [5] It is a specific case of deep gluteal syndrome. [6] The largest and most bulky nerve in the human body is the sciatic nerve. Starting at its origin it is 2 cm wide and 0.5 cm thick.
A transcutaneous electrical nerve stimulation (TENS or TNS) is a device that produces mild electric current to stimulate the nerves for therapeutic purposes.TENS, by definition, covers the complete range of transcutaneously applied currents used for nerve excitation, but the term is often used with a more restrictive intent, namely, to describe the kind of pulses produced by portable ...
The piriformis nerve, also known as the nerve to piriformis, is the peripheral nerve that provides motor innervation to the piriformis muscle. Structure Origin ...
Piriformis syndrome is a condition that, depending on the analysis, varies from a "very rare" cause to contributing up to 8% of low back or buttock pain. [16] In 17% of people, the sciatic nerve runs through the piriformis muscle rather than beneath it. [15]
The main epidemiological data available is on piriformis syndrome. Due to challenges in defining and diagnosing piriformis syndrome, attempts at quantifying its prevalence have led to conflicting estimates. Recent estimates for the prevalence of piriformis syndrome are 6% and 17% of all patients with low back pain / sciatica. [8]

[1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
