sorry phunphysio if I gave you the wrong impression
As paediatric physiotherapists, the only way to assess a newborn is to observe spontaneous movement, the way the child reacts after to a sudden change in posture and of course the quality of the GM´s and that is not easy at all. A good developmental neurologist may be able to say more about sensation and be able to test it.
The TES I was talking about has been used on an much older child effectively apparately... go to TASC Network for more information.
I have personally never used electrotherapy with very young children/babies at all. As far as I know, the Dutch specialialized Brachial Plexus University Teams have never advocated its use.
For more information on the GM´s go to Ontwikkelingsneurologie|Developmental Neurology
kind regards
