A heavily scrutinized anatomic variation involves sciatic nerve branching around the piriformis using the 6 category classification first described by Beaton and Anson. In this classification, the normal anatomy (type A) seen in about 80% of people is where the sciatic nerve passes under the piriformis muscle at the greater sciatic notch.
[20] [21] There are now many known causes of sciatic nerve entrapment, such as fibrous bands restricting nerve mobility, that are unrelated to the piriformis in the deep gluteal space. Deep gluteal syndrome was created as an improved classification for the many distinct causes of sciatic nerve entrapment in this anatomic region. [ 21 ]
The symptoms of low back pain usually improve within a few weeks from the time they start, with 40–90% of people recovered by six weeks. [2] In most episodes of low back pain a specific underlying cause is not identified or even looked for, with the pain believed to be due to mechanical problems such as muscle or joint strain.
Diminished or absent sciatic nerve mobility is believed to be the precipitating cause of sciatic neuropathy in deep gluteal syndrome. [6] This impaired mobility induces strain and compression on the sciatic nerve during various hip movements. [7] Even a 6% stretch on a nerve can result in impaired conduction. [15]
Symptoms may include sensory changes such as numbness, tingling, paresthesia, and motor changes such as muscular weakness, paralysis, and affection of reflexes. If the herniated disc is in the lumbar region, the patient may also experience sciatica due to irritation of one of the nerve roots of the sciatic nerve.
Acupuncture successfully reduced pain and disability for people with chronic sciatica in a randomized clinical trial in China. Their improvement, compared to those receiving sham acupuncture ...
