title: Spontaneous movements with various seated-workplace adjustments.
abstract: Movement patterns in 10 healthy subjects sitting on an office chair with either a tiltable seat, a 5° forwards, or 5° backwards inclining seat were investigated; also the effect of a slanted tabletop desk were studied. The subjects were performing reading and writing tasks. They were investigated twice for one hour on each of two days. Movement pattern was evaluated using counting of movements from videotape recordings of the subjects. Also the subjects' impressions of comfort in the various settings were investigated using a five-point rating scale. The main conclusion is that there exist no significant differences in either the number of movements or in comfort evaluation between the four settings investigated.
