- Background: Multimodal rehabilitation and tailored behavioral medicine treatments should be provided to patients suffering from persistent and activity limiting pain according to current state-of-science. There is also evidence that a minimal intervention including 'stay-active advice' can produce effects comparable to effects of comprehensive treatment packages. Nevertheless, there is a gap of knowledge regarding which individuals who benefit the most from which modalities of pain treatment, at what time point, and with the highest cost-effectiveness. Accordingly, we have set up an innovative stepped-care protocol for the management of musculoskeletal pain in primary care, which is evaluated in a randomized controlled trial.Objectives: The aim is to compare effects and cost-effectiveness of a stepped care model including advice and tailored behavioral medicine pain treatment (experimental condition) with a stepped care model including advice and physical exercises (comparison condition) for patients with low back and neck pain and/or widespread pain including fibromyalgia in primary care. A further aim is to characterize patients who benefit/do not benefit from the respective steps i.e. treatments varying in dose and content.Methods: A stratified randomized stepped care design is applied. Stratification is based on primary care center and psychological risk profile. A consecutive selection is performed at primary care centers in southern, central and northern Sweden. After having received a minimal intervention (step 1) comprising 'stay-active advice', participants scoring high on the Örebro Musculoskeletal Pain Questionnaire (ÖMPQ) according to preset criteria are randomly allocated to an eight-week treatment in step 2. The experimental condition includes supervised physical exercises integrated with either (a) graded activity, or (b) hierarchical graded exposure depending on psychological risk profile. The comparison condition includes supervised physical exercises irrespective of risk profile. Primary outcome is pain-related disability complemented with a comprehensive set of secondary outcomes adhering to the IMMPACT recommendations.Results: The stepped-care design will be presented including illustrations of conclusions possible to draw with this kind of innovative design.Conclusions: There is a call for stepped-care interventions within pain intervention research, particularly in the primary care setting. However, published studies are still lacking. This study will contribute to an important progression of behavioral medicine pain treatments by the way treatments are tailored in accordance with psychological risk profile. This will be discussed to stimulate research activities and collaboration within this area of research and clinical implementation.

- Context-aware applications and services require ubiquitous access to context information about the users or sensors such as preferences, spatial & environmental data, available connectivity, and device capabilities. Systems for the brokering or the provisioning of context data via wireless networks do so with centralized servers or by employing protocols that do not scale well with real-time distribution capabilities. In other cases, such as the extending of presence systems, the data models are limited in expressive capabilities and consequently incur unnecessary signaling overhead. This paper presents a distributed protocol, the Distributed Context eXchange Protocol (DCXP), and an architecture for the real-time distribution of context information to ubiquitous mobile services: We present the architecture and its principle operation in a sample ubiquitous mobile awareness service. Preliminary results indicate that our approach scales well for the ubiquitous provision of context data in real-time to clients on the Internet via 3G wireless systems. Performed measurements show that DCXP can reduce the time to process context data with a factor of 20 compared to similar approaches.

- Mobile telecommunication is evolving rapidly. People no longer only communicate with each other regardless of time and place, but also share other information that is important for tasks with which they are involved. In response to this growing trend the MediaSense framework addresses the intelligent delivery of any information to any host, anywhere, based on context-aware information regarding personal preferences, presence information, and sensor values. This includes another challenge to achieve seamless delivery, especially of multimedia content, and multimodal services via heterogeneous connections.

- Users require applications and services to be available everywhere,enabling them to focus on what is important to them. Therefore, contextinformation (e.g., spatial data, user preferences, available connectivity anddevices, etc.) has to be accessible to applications that run in end systems closeto users. In response to this, we present a novel architecture for ubiquitoussensing and sharing of context in mobile services and applications. Thearchitecture offers distributed storage of context derived from sensor networkswirelessly attached to mobile phones and other devices. The architecture alsohandles frequent updates of sensor information and is interoperable withpresence in 3G mobile systems, thus enabling ubiquitous sensing applications.We demonstrate these concepts and the principle operation in a sampleubiquitous Mobile Awareness service.

The support handles frequent updates of sensor information and is interoperable with presence services in 3G mobile systems, thus enabling ubiquitous sensing applications. We demonstrate these concepts and the principle operation in a sample ubiquitous mobile awareness service. The importance of this contribution, in comparison to earlier work, lies in the availability of real-time ubiquitous sensing to both applications on the Internet as well as applications in mobile systems.

Tidskriftsartikel (refereegranskat)abstract
- Background: Monitoring elite athletes’ body composition (BC) is vital for health and optimizing performance in sports emphasizing leanness, such as athletics. This study aims to investigate and compare sex- and event-specific off-to in-season BC changes in endurance and power event athletics competitors.Methods: Elite male and female endurance athletes (> 800 m runners; n = 21) and power event athletes (sprinters, jumpers; n = 32) underwent dual-energy X-ray absorptiometry (DXA) scans for whole and regional lean mass (LM), fat mass (FM), bone mineral content (BMC), and density (BMD) during off-season (September-October) and in-season (April-May). Linear mixed models tested between-group off-season differences in BC, within-group off-season to in-season changes, and between-group differences in change. To assess meaningful or least significant changes (LSC) in BC, DXA precision errors were determined from two consecutive total body scans in a subsample of athletes (n = 30).Results: Male athletes (n = 26) gained significantly (p < 0.05) more body mass (BM; mean difference 1.5 [95% confidence interval (CI):0.5–2.4] kg), LM (843 [95% CI:-253:1459] g), and trunk LM (756 [-502:1156] g) than female athletes (n = 27). The proportion of changes in athlete’s BC exceeding the LSC threshold for LM and trunk LM were 70% and 65% in males, and 48% and 26% in females. Significant (p < 0.05) within-group off-season to in-season increases in LM were found for male endurance and power athletes, and female power athletes. All groups significantly increased BMD (p < 0.05). Only male and female power athletes had significant in- to-off-season increases in BMC. 80% of all athletes who had a meaningful increase in BMC belonged to the power event group. No significant within- or between group change in FM was observed.Conclusions: The present study found that male athletes gained more BM, LM and trunk LM than females. Within-group increases in regional and whole-body LM and BMC were predominantly found among power event competitors. Incorporating individual meaningful changes alongside traditional statistics provided additional insights into sex and event-group differences. Future research on elite athletic event groups should include DXA measurements closer to major outdoor-season competitions, coupled with site-specific measures (ultrasound, MRI) for better detection of subtle changes in LM and FM.
