Sciatic nerve mobilization

Nerve Mobilization Increases Ankle Dorsiflexion

A study like this is important because it provides evidence-based proof that there is efficacy to the treatment technique known as nerve mobilization.

What are the signs and symptoms of sciatica?

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.

What is sciatica?

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.

Back Extension McKenzie Exercises Effect on Disc Fluid

The authors concluded that little evidence was found supporting the hypothesis that extension McKenzie exercises affect disc fluid content.

Straight Leg Raise Tests for a Space-Occupying Lesion

Both active straight leg raise and passive straight leg raise tests are designed to tension the sciatic nerve to assess a space-occupying lesion.

Valsalva Maneuver (Test)

Cough Test and Valsalva Maneuver Orthopedic Assessment Tests

Cough test and Valsalva maneuver are designed to increase intrathecal pressure, or pressure on the spinal nerves in the intervertebral foraminal spaces.

Piriformis Syndrome

Piriformis syndrome is a condition in which the piriformis muscle compresses the sciatic nerve, causing symptoms of sciatica into the lower extremity.

Pathologic Disc Conditions of the Lumbar Spine and Sciatica

A pathologic disc can compress the sciatic nerve resulting in sciatica. Although any pathologic disc is potentially serious.

Precautions for Manual Therapy of the Lumbar Spine and Pelvis

The low back and pelvis contain a number of sensitive structures whose locations are important to know because they contraindicate deep pressure.

Figure-4 stretch for piriformis syndrome

What are the self-care and medical approaches to piriformis syndrome?

Self-care for piriformis syndrome involves heat followed by stretching. The client can perform either the Figure-4 or the horizontal adduction stretch.

How do we treat piriformis syndrome with manual therapy?

Manual therapy treatment for a tight piriformis (that can cause piriformis syndrome) involves moist heat, soft tissue manipulation, and stretching.

The sciatic nerve exits between the piriformis and superior gemellus. Compression here is termed piriformis syndrome

Signs, symptoms, and assessment (diagnosis) of piriformis syndrome

Piriformis syndrome causes compression upon the sciatic nerve; therefore it causes symptoms of sciatica, similar to sciatic nerve entrapment at the spine.

piriformis syndrome occurs when the sciatic nerve is compressed between the piriformis and the superior gemellus (seen here)

What is piriformis syndrome and what are its causes?

Piriformis syndrome occurs when a tight piriformis muscle compresses against the sciatic nerve, causing symptoms of sciatica into the lower extremity.
