Trendelenburg Test
(Redirected from Trendelenburg's Sign)
Other Names
- Trendelenburg's Sign
- Trendelenburg Gait
- Modified Trendelenburg Test
Purpose
- Evaluate the strength of the hip abductors, specifically Gluteus Medius and Gluteus Minimus
Description of Test
- The patient is standing on their affected leg for approximately 30 seconds without leaning
- They can stabilize themselves on the examination table or examiner if needed
- Examiner examines patient to observe for stability or level of pelvis during single leg stance
- Comparison should be made to the unaffected limb
- Positive test
- Unilateral weight bearing the pelvis drops toward the unsupported side
Trendelenburg Gait
- Essentially identical to Trendelenburg test, except you observe gait instead of single leg stance
- Positive test
- Inability to maintain balance or pelvic stability
- Lateral tilt of the trunk away from the affected hip
Pathology
- Weakness of gluteus medius
- Greater Trochanteric Pain Syndrome
- Hip instability and subluxation
- Hip osteoarthritis
- Initially post Total Hip Replacement
- Superior Gluteal Nerve Palsy
- Lower back pain
- Legg-Calvé-Perthes Disease
- Congenital hip dislocation
