A 16-year-old girl with progressive weakness of the left leg.

摘要

The patient first noted problems in 1996, almost 3 years prior to evaluation. She had fallen and injured her right knee on a brick. The onset of her left lower extremity problems was uncertain, but she noticed gradual weakness of her left foot subsequent to the injury. In January 1999, the weakness of the left foot was noted to be definite. Her left foot would slap with walking, and her mother would encourage her to "pick up her foot" when she walked. Her grandmother noted that she would often scuff her left foot. The patient experienced no pain with the weakness, and she herself was only aware of it while trying to run. The patient felt she had been unable to run properly for the last 2 to 3 years.
