Purpose
[edit | edit source]

The purpose of the Trendelenburg Test is to identify weakness of the gluteus medius muscle.

Technique
[edit | edit source]

The patient is asked to stand on one leg for 30 seconds without leaning to one side.  The therapist obsereves the patient to see if the pelvis stays level during the one-leg stance.  A positive Trendelenburg Test is indicated if during unilateral weight bearing the pelvis drops toward the unsupported side[1].

Several dysfunctions can produce a positive Trendelenburg Test, including[2]:

  • Superior Gluteal Nerve Palsy
  • Lumbar disk herniation
  • Weakness of gluteus medius
  • Advanced degeneration of the hip
