Abstract [en]

Many schoolchildren frequently use computers. Lack of postural variation is proposed as a risk factor for musculoskeletal disorders (MSDs) in adult computer users, but the effect of computer use on children's postural t variation is unknown. This study exarnined if there was a reduction in postural variability among schoolchildren when ! using computers compared to other tasks. Nine schoolchildren were observed in their natural environment while upper body postures were measured using inclinometers. Tasks performed and type of technology used was documented by an observer and matched to postural data with a rninute-to-rninute resolution. A comparison was made of postures during New Information and Communication Technology (ICT) tasks ( electronic-based), Old ICT (paperbased), and Non ICT tasks. Mean postures were deterrnined and postural variation was characterised using an index based on the Exposure Variation Analysis (EV A) matrix, and the range between the 10th and 90th percentiles of the Amplitude Probability Distribution Function (APDF). New ICT produced more neutral postures but significantly lower postural variation. Old ICT had less neutral postures but greater postural variation. The relationship between lack of variation and MSDs among children requires further investigation.
