Video Link

Background/Purpose

Procedure

The subject is supine with both hips and knees extended. The examiner slowly raises the test leg until pain or tightness is noted. Pain in the leg produced from 0 to 30 degrees indicates nerve root compression. Sciatica produced between 30 and 60 degrees indicates sacroiliac disease. Sciatic pain produced with leg motion beyond 60 degrees points to lumbosacral conditions.
Performed: Unilaterally

Dialog

With patient supine, passively raise straight leg into hip flexion.

Criteria

• Radicular leg pain should occur (radiating below the knee).
• Pain occurs when the leg is between 30 and 60 or 70 degrees from horizontal.
