A study like this is important because it provides evidence-based proof that there is efficacy to the treatment technique known as nerve mobilization.
The exact location of the symptoms of sciatica would be determined by which neurons are compressed; in other words, which nerve root level is affected (from L4 to S3), and whether they are sensory or motor neurons.
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 authors concluded that little evidence was found supporting the hypothesis that extension McKenzie exercises affect disc fluid content.
Both active straight leg raise and passive straight leg raise tests are designed to tension the sciatic nerve to assess a space-occupying lesion.
Cough test and Valsalva maneuver are designed to increase intrathecal pressure, or pressure on the spinal nerves in the intervertebral foraminal spaces.
Piriformis syndrome is a condition in which the piriformis muscle compresses the sciatic nerve, causing symptoms of sciatica into the lower extremity.
A pathologic disc can compress the sciatic nerve resulting in sciatica. Although any pathologic disc is potentially serious.
The low back and pelvis contain a number of sensitive structures whose locations are important to know because they contraindicate deep pressure.
Self-care for piriformis syndrome involves heat followed by stretching. The client can perform either the Figure-4 or the horizontal adduction stretch.
