View Full Version : Workload assessment from the EMG data collected from relativelylong period

01-28-2009, 04:55 AM
Dear fellow subscribers,

I collect EMG data in addition to motion analysis & force plate data for
assessing the physical workload associated with performing laparoscopic
surgery. While it still depends on the surgical tasks, I usually use 12 to
16 channels at 1 KHz for 10 to 15 minutes. I would like to get some advise
on how I can calculate overall workload of the entire period of time. One
way I could think of was to take integration of normalized EMG profile
(continuous data shown as %MVC) over time. I would like to know what
drawback this method does have and what better ways you would recommend.
Your comments will be very appreciated. Thank you.
