Brian, a 4-year-old boy, is demonstrating the Gower's sign, and his mother is wondering why her child is making this movement. The child is doing this because:
 
  1. The weakness of his arms requires his legs to do more work.
   2. The weakness in his hips and thighs requires help from his arms to stand.
   3. Weakening trunk and back muscles require the legs and arms to help keep an upright position.
   4. Weakening of the trunk requires this movement to help breath.

Question 2

1. The weakness is in the hips and thighs, not the arms.
2. The weakness in the hips and thighs makes it difficult to stand, thus requiring the arms to help provide stability.
3. The trunk and back muscles are weak, but are not the reason for the Gower's sign.
4. The Gower's sign is seen when attempting to stand.
