Successful assessment/diagnosis of sciatica depends upon successfully assessing the underlying cause of the sciatic nerve compression.
Sciatica is a condition in which the sciatic nerve is compressed, causing referral symptoms (often pain or numbness) into the lower extremity. The referral symptoms can be sensory and/or motor depending on whether sensory or motor neurons are compressed.
The following is a brief overview that links the low back condition with its corresponding assessment procedure and its corresponding treatment.
The piriformis stretch test is used to assess piriformis syndrome, that is, compression of the sciatic nerve by the piriformis.
A pathologic disc can compress the sciatic nerve resulting in sciatica. Although any pathologic disc is potentially serious.
Self-care for piriformis syndrome involves heat followed by stretching. The client can perform either the Figure-4 or the horizontal adduction stretch.
