<s>[INST] My uncles daghter is 3 months old and isnt able to move her neck or one arm. Her mom fell down the stairs when she was a few weeks old she didnt think she hurt the baby. Now shes being tested for all these diseases (mainly cerebal palsy) could she have an injury from the fall? Pinched nerve or something like that [/INST] If at this month of age he or she not able to move head and arm thinks in the line of cerebral palsy or floppy infant. If significant birth history is there then strong possibility of cerebral palsy. Go for mri. That may give some clue. </s>
