dear doctor,

a 2-year old girl has difficulty to walk and her right leg become smaller day by day since 3 months ago.
around 6 months ago, she suffered from a very high fever, but her parent just gave her traditional herbal medicine n the fever disappeared after a few. unfortunately, 2 weeks later, this girl looked lazy to stand up n preferred sitting. this girl never had immunization and was delivered normal, at home, by traditional birth attendant.

so, my questions are.
1) did this girl developed the muscle atrophy due to the polio virus?
2) what is the rehabilitation procedure can be applied to this girl? i mean the exercise to increase the muscle strength, the types of drug that can improve the augmentation of the ACh and what is the growth factor for the nerve development?
thank you doctor~ i really appreciate if you can answer my questions.
