Purpose – The aim is to explore users' reactions to health information web sites from the perspective of trust, retrieval of relevant information and ease-of-use, and to establish the link between perceived quality, trust, and usability. Design/methodology/approach – An analysis of three Australian health web sites was undertaken. A usability test was conducted on those three web sites resulting in 207 completed user evaluations. The evaluations included both quantitative and qualitative data. Findings – The three investigated health information web sites do not meet the needs of health consumers. More details such as how information is selected to engender greater trust need to be provided. The retrieval of relevant information could be improved through the implementation of functionality such as spell checking and information differentiation. Finally, ensuring web sites are easy to use contributes to the level of trust users have in a web site. Research limitations/implications – This was a relatively small study investigating only three generic Australian health web sites, the results however suggest that a larger study looking at other health web sites is needed. Practical implications – For government agencies developing health information web sites more attention needs to be paid to the design of these web sites if users are to be encouraged to use the web site and return. The research suggests that effective health information web sites must be perceived to be of reliable quality, be trustworthy, have some level of intelligence to assist in the retrieval of relevant information, and be easy to use. Originality/value – Although there is much research relating to the relationship between web site design and trust for e-commerce transactional web sites this work has not been undertaken for web sites designed for information retrieval, in particular little work has been done of health information web sites. This paper fills in some of the gaps.

Background: A nanomaterial-based electronic-skin (E-Skin) wearable sensor has been successfully used for detecting and measuring body movements such as finger movement and foot pressure. The ultrathin and highly sensitive characteristics of E-Skin sensor make it a suitable alternative for continuously out-of-hospital lumbar–pelvic movement (LPM) monitoring. Monitoring these movements can help medical experts better understand individuals’ low back pain experience. However, there is a lack of prior studies in this research area. Therefore, this paper explores the potential of E-Skin sensors to detect and measure the anatomical angles of lumbar–pelvic movements by building a linear relationship model to compare its performance to clinically validated inertial measurement unit (IMU)-based sensing system (ViMove). Methods: The paper first presents a review and classification of existing wireless sensing technologies for monitoring of body movements, and then it describes a series of experiments performed with E-Skin sensors for detecting five standard LPMs including flexion, extension, pelvic tilt, lateral flexion, and rotation, and measure their anatomical angles. The outputs of both E-Skin and ViMove sensors were recorded during each experiment and further analysed to build the comparative models to evaluate the performance of detecting and measuring LPMs. Results: E-Skin sensor outputs showed a persistently repeating pattern for each movement. Due to the ability to sense minor skin deformation by E-skin sensor, its reaction time in detecting lumbar–pelvic movement is quicker than ViMove by ~1 s. Conclusions: E-Skin sensors offer new capabilities for detecting and measuring lumbar–pelvic movements. They have lower cost compared to commercially available IMU-based systems and their non-invasive highly stretchable characteristic makes them more comfortable for long-term use. These features make them a suitable sensing technology for developing continuous, out-of-hospital real-time monitoring and management systems for individuals with low back pain.
