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:

To determine the gait associated with bilateral gluteal muscle weakness, we analyze each option:

• Parkinson Gait (a) is due to Parkinson’s disease, involving shuffling.
• Waddling Gait (b) occurs with hip abductor weakness (e.g., muscular dystrophy) but differs from bilateral gluteal weakness.
• Trendelenburg Gait (c) results from gluteus medius/minimus weakness (part of gluteal muscles), causing a pelvis drop on the opposite side during stance. Bilateral gluteal weakness leads to a characteristic waddling or lurching with pelvic instability, matching Trendelenburg (bilateral presentation).
• Antalgic Gait (d) is pain - induced, not muscle weakness - related.

Thus, bilateral gluteal muscle weakness causes Trendelenburg Gait.

Answer:

c) Trendelenburg Gait
