Postural Deviation Gestures Distinguish Perceived Pain and Fatigue Particularly in Frontal Plane

Abstract

Office workers frequently report discomfort in the neck, back and shoulders. Extreme and prolonged static postures are known risk factors. Sit-stand workstations encourage regular postural changes and tend to reduce discomfort. Head and upper back deviations were recorded for ten adults entering data using a seated desk and two sit-stand desks following three twenty-minute cycles with 6 or 9 min standing. Participants reported their perceived back pain, neck pain and fatigue following each recording.
