Hi,
I was using a body worn tri-axial accelerometer for measuring sway during standing balance, I fixed the accelerometer upside down i guess as i got all the values in negative (i figured it out with the vertical component data). does it affects my data, any suggestion to correct it?

Hi Thorsten,
Thanks for your reply. I also have few other questions if you can clarify. In the literature, I have read something about eliminating gravitational component followed by filtering the data in the accelerometer. As I am from medical background I don't have much knowledge on this. do you know something about this and filtering a accelerometer data measured at 100hz sampling rate.
