Questions and Answers
  • 1. 
    A 28 year old woman, who is a regular client of yours, fell on the ice over a month ago as she ran to catch her bus to work. She landed heavily on her left elbow and sustained a complete ulnar nerve lesion. The elbow swelling and bruising are now well on the way to subsiding, although her ulna is still very tender to pressure. She was on an analgesic and an anti-inflammatory for 10 days following the injury, but is not taking anything now. Her neurologist has said that while there should be good recovery, a full return to function is not guaranteed. He has given her a neutral wrist brace to wear at night. Please assume that the injury eliminated ALL ulnar nerve functions and at this time, no signs of recovery have begun. Her forearm pronation is:
    • A. 

      Paralyzed.

    • B. 

      Paretic.

    • C. 

      Neurologically normal.

    • D. 

      Unopposed.
