- The aim of this study was to determine whether there are differences in exposure, comfort, exertion and productivity between a neutral and a pronated hand position when using a computer mouse. Nineteen experienced VDU workers performed a standardised text editing task with each mouse hand position. The wrist positions and movements in the working arm were registered by an electrogoniometer and the muscle activity in the shoulder, two extensors in the forearm and the first dorsal interossei (FDI) was registered by electromyography. The subjects rated perceived exertion and comfort in work with each mouse hand position. Work with the neutral hand position, compared to the pronated, gave a decreased muscle activity in the extensors of the forearm and in the FDI and a trend indicating a decrease in the frequency of deviation movements in the wrist. At the same time, the subjects showed a decreased productivity and they rated less comfort in work with the neutral hand position.

The use of information technology among young adults--experience, attitudes and health beliefs

Journal article (peer-reviewed)abstract
- The aim of this study was to explore attitudes, coherence and health beliefs among young adults, related to their use and experience of information technology (IT). A qualitative approach was used and the data were collected through individual thematised interviews with 25 young IT users, aged 18-24. The interviews were analysed in line with the grounded theory method with a constructivist approach. The main findings were the young adults' experience of the two sides of being social, efficient and independent here and now. They described almost unlimited opportunities in connection with IT, but they also had misgivings, and perceived risks regarding IT use. Feelings of freedom and being efficient were countered by feelings of restrictions on living space and of intangibility. Knowledge concerning these attitudes, coherence and health beliefs can be considered when designing epidemiological and ergonomic studies aimed at risk identification.
