The demonstrated abnormality is seen in paralysis of?
Correct Answer: Both 2 & 3
Description: In this video, the patient is waking lurching gait or a.k.a duck waddling gait. In paralysis of the hip muscles gluteus medius and minimus , the gait is described as "duck-like waddle(Waddling gait) or Sailors gait or Trendelenburg gait and consists of an inclination to the side on which the weight is born i.e. the normal side(lurching gait on both sides in case of bilateral involvement) B/L dislocation of hip from bih can also produce this type of gait. Gluteus maximux paralysis is seen in polio CROUCHING GAIT is seen. Trendelenburg test:It is impoant to understand the mechanism of this test to understand Trendelenburg gait. Normal two legged stance: Center of the gravity is midway between the two feet. Normal single legged stance: Center of gravity shifts towards the affected side. To allow this to occur efficiently, the pelvis iseffectively pulled up (by the motor) on the unsuppoed side and the centre of gravity is shifted directly over the standing foot. In clinical examination this is revealed by localizing and placing a finger on each anterior superior iliac spine (ASIS). As the patient stands on one leg the finger on the ASIS of the unsuppoed leg will rise. This is a normal response and would be recorded as Trendelenburg negative Pathology of the hip joint or paralysis of the gluteus medius and minimus If the pelvis drops on the unsuppoed side, to avoid falling, the person has to throw his body towards the loaded side so that the centre of gravity is again over that foot. In this instance the finger on the ASIS of the unsuppoed leg will fall. Sound side sags: Mnemonic
