Question

weakness of bilateral gluteal muscles will result in what type of gait presentation?
a) parkinson gait
b) waddling gait
c) trendelenburg gait
d) antalgic gait

Explanation:

• Parkinson Gait is due to Parkinson's disease (rigidity, bradykinesia).
• Waddling Gait is from proximal muscle weakness (e.g., Duchenne muscular dystrophy).
• Trendelenburg Gait occurs with gluteal muscle weakness (bilateral weakness causes a waddling - like shift but specifically from gluteus medius/minimus weakness affecting pelvic stability).
• Antalgic Gait is pain - related (shortening stance on painful leg).

Bilateral gluteal muscle weakness leads to Trendelenburg Gait as these muscles stabilize the pelvis during gait.

Answer:

c) Trendelenburg Gait
