dear mark,
A really up-to-date boek which includes all aspects of cerebral palsy treatment has just been published and it includes a CD-ROM with lots of images. Its called Physical Therapy of Cerebral Palsy, by Freeman Miller isbn-13 978-0-387-38303-3 and can be ordered on line at www.springer.com
p.s. I would suggest you buy this and i am not involved in any way. just a paediatric physio with lots of books and this one is not bad at all.
