Selecting Change in Data from a Multiple Columns

Hi,

I have a project where I am populating data across multiple columns with a time vector (Motion Capture Data), what I would like to do is create a small for loop which finds the initial starting point of muscle movement, that is it would automatically find the time data in the time column, for which the average of the other columns changes by over 10% (aka the data changed more than 10% due to someone moving their location)

Does anyone have any ideas how I would go about doing this? (As well as possibly figure out how to do the same thing for the end of the data set)

Thanks
