Hi! I think I've replied quite late. I have been treating infants with erb's palsy for 5 years at most. In my experience, i realized that the best way to treat erb's palsy initially is PROPER POSITIONING and gentle ROMEx. Teach parents to position the infant in adduction,internal rotation and supination so as to protect the limb.You can tell them to pin the sleeve to the baby's shirt or diaper.As the baby grows use active exercises appropriate for his age,i.e.,reaching,grasping and releasing.When doing ROMEx, be sure to allow scapular movement,and avoid overstretching flaccid muscles.Until now, neuromuscular stimulation is controversial,but if you want to try,use the probe to stimulate specific muscles.Good luck!
