The therapist’s session consisted of moist heat, soft tissue manipulation, and stretching to the low back with double knee to chest stretch performed with agonist contract technique and stretching the left side of the low back with Armin side-lying on his right side.
It is necessary to determine what condition is causing the sciatic nerve compression and address that. If the cause is a pathologic disc, then addressing factors that affect disc compression is appropriate.
Successful assessment/diagnosis of sciatica depends upon successfully assessing the underlying cause of the sciatic nerve compression.
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.
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.
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.
Self-care for piriformis syndrome involves heat followed by stretching. The client can perform either the Figure-4 or the horizontal adduction stretch.
Piriformis syndrome occurs when a tight piriformis muscle compresses against the sciatic nerve, causing symptoms of sciatica into the lower extremity.
A herniated disc in the neck refers symptoms into the upper extremity. A herniated disc in the low back refers symptoms into the lower extremity (sciatica).
