Actigraphy in Hyperactivity

[Wayne M. Cohen]

Hello.  I am a member of a research group looking at the possibility
of using actigraphy to evaluate patients with hyperactivity and 
repetitive motion disorders.  I would like to ask whether anyone has 
experience with using actigrapy for this purpose.  We have experience 
with the technology in evaluating sleep patterns.  Just wanted to findout 
if we need to develop data analysis methodologies, of if they already 
exist.  Thanks for any input.
