Merging
editIMO, Actigraph should be merged into Actigraphy, with Actigraph redirecting to Actigraphy. Then Actimetry should redirect to Actigraphy as well.
Actigraphy is the term used in the US, see: http://www.aasmnet.org/Resources/PracticeParameters/PP_Actigraphy_Circ.pdf , while it's possible that actimetry is used in Canada(?).
Actigraphy is the process, similar to Polysomnography; polysomnograph redirects to polysomnography. Explanations / descriptions of the process, its reasons and uses, and the device used all fit nicely within an article entitled Actigraphy. --Hordaland (talk) 23:05, 21 January 2008 (UTC)
