Likely movement frequency content for head, trunk, upper arm movement (computers)
I am analysing 2D inclinometer data captured through sensors recording at 15 Hz on each of the head, thoracic trunk, and left and right upper arms considering sagittal, frontal déviations. These recorded during computer data entry tasks using different styles of Workstation and postural support (sit-stand, stand, sit, rear leaning).
I would like to reduce the data to be analyses to analyse patterns without ignoring important data. During upper-limb focussed ADLs (activities of daily living), I determined that 6 Hz was a conservative cut-off for the low-pass forward-backward Butterworth filter. Does anyone know of litterature that addresses the likely highest frequency components for the body sements I am following, particularly during a largely sedentary task like computer data entry?
Thank you in advance
