Bragard’s Test

Bragard’s Test is an orthopedic maneuver designed to confirm nerve root irritation, particularly of the sciatic nerve due to lumbar disc herniation or radiculopathy. It is considered a refinement or adjunct to the classic Straight Leg Raise (SLR) Test.

Bragard’s Test

How the Test is Performed

  • Client position: Supine (lying on the back), both legs straight.

  • The therapist performs a Straight Leg Raise on the affected side, noting the angle where radiating pain or symptoms occur (typically between 30°–70° of hip flexion).

  • The leg is then lowered slightly (about 5–10 degrees) from the symptomatic angle, until discomfort resolves.

  • The therapist then passively dorsiflexes the foot (bringing toes toward the head) while holding the hip and knee in position.

  • A positive Bragard’s Test: Reproduction of radiating pain, burning, tingling, or numbness in the same distribution as the original SLR.

  • If only calf tension (not radiating pain) is produced, it is considered negative for nerve involvement and more suggestive of hamstring or muscular tightness.

Clinical Significance

  • A positive test points to nerve root compression (L4–S1), sciatic nerve irritation, or lumbar disc herniation.

  • Helps differentiate neural tension from muscle or joint causes of posterior leg pain, such as tight hamstrings or hip pathology.

  • Sensitivity and specificity are moderate (sensitivity ~22–92%, specificity ~43–100% depending on studies and populations).

  • Also used as a tool to assess non-organic pain or to distinguish malingering (symptoms usually absent in non-organic causes).

Assessment

  • Use Bragard’s Test when a client presents with low back pain, radiating buttock/leg symptoms, suspected sciatica, or following a positive SLR.

  • Document the precise angle, symptom description, and whether the test reproduces classic neural pain or only stretches the calf.

Treatment

  • If positive (radiating neural pain):

    • Avoid vigorous or deep techniques to the lumbar spine, piriformis, or sciatic pathway that could exacerbate irritation.

    • Focus on gentle modalities, pain-modifying techniques, and education regarding posture and activity modification.

    • Collaborate with physiotherapists and refer for further assessment/imaging if symptoms are marked or progressive.

  • If negative: May indicate muscular tightness or non-nerve cause. The therapist should perform gentle stretching and myofascial release as tolerated.

Safety and Referral

  • Refer promptly if there is significant, progressive, or functionally limiting neural pain, persistent weakness, or “red flag” symptoms (saddle anesthesia, bowel/bladder incontinence, severe motor loss).

  • Provide clear documentation for interdisciplinary care and outcome monitoring.
