Re: [申覆] 醫學六 66
※ 引述《ClydeDrexler (ClydeDrexler)》之銘言：
: 66. 裘馨氏肌失養症（Duchenne muscular dystrophy）的患童常以德氏步態（
: Trendelenberg gait）走路，是因為下列那一條肌肉無力所造成？
: (A)髂腰肌（iliopsoas） (C)臀中肌（gluteus medius）
: (B)臀大肌（gluteus maximus）(D)髖內收肌（hip adductors）
: 原答案：B
: 建議答案：送分
: 申覆理由：
: 德氏步態應該是 Trendelenburg gait
: 這樣申覆有用嘛 =.=
鴕鳥沒對答案，剛剛才發現此篇
gluteus medius gait pattern: (see gluteus medius);
- characterized by a Trendelenberg gait pattern;
- abductor insufficiency and is most commonly seen in patients
with polio
- weakened medius; allows opposite side of pelvis to tilt downward
during stance on weakened side;
- contralateral hemipelvis drops during the single-limb
stance phase on the affected side
- in effort to compensate, the trunk lurches toward weakened side
(abductor lurch) during stance;
- this action moves the center of gravity nearer fulcrum on weak
side, shortening the moment arm from the center of gravity to hip
joint & reducing effort required of the abductors of hip;
- references:
- The significance of the Trendelenburg test
- Can Trendelenburg's sign be positive if the hip is normal?

如果答案真的是b就虧了
