Review of physical activity measurement using accelerometers in older adults: Considerations for research design and conduct

My research topic is to examine the effects of different exercise types on sleep in people with insomnia.
The purpose the review article was written was to provide researchers with a guide to the most commonly used devices used to measure physical activity. The article talked about the different types of accelerometers available today as well as parameters with which to use these various monitors. These parameters varied depending on the device but included the number of days the device should be worn and where the monitors should be placed. The article included very informative charts that compared these various devices. The article also provided some information to the reader on choosing the right measurement device for their particular study.
This article was very helpful in giving me information about the Actical, the device I plan on using in my study to help measure physical activity.
I was also given the IRB packet for a CBTi study at Fort Hood funded by a DOD (Department of Defense) grant by Dr.Taylor. Of particular interest to me is the methods section of the packet because it is similar in design to the one I plan on doing.
