- Sleep duration and sleeping difficulties among adolescents: exploring associations with school stress, self-perception and technology use Sleeping problems are increasing among adolescents worldwide. This study aimed to describe the prevalence of self-reported sleep duration and sleeping difficulties, as well as to explore their associations with school stress, self-perception, that is how adolescents perceive their appearance and happiness, and technology use among adolescents. Data were collected in 2015 using a questionnaire. A total of 937 ninth grade adolescents, 15–16 years, from a city in western Sweden participated, resulting in a response rate of 83%. The result showed that 55% of the adolescents slept less than the recommended 8 hours per night and 11% had sleeping difficulties. School stress and technology use were associated with short sleep duration. School stress and self-perception were associated with sleeping difficulties. The girls had worse outcomes for sleeping difficulties, school stress, self-perception and technology use than the boys. Based on the results, there is a need for school nurses to implement preventive measures to improve adolescents’ sleep.

Tidskriftsartikel (refereegranskat)abstract
- Background: To develop a novel wearable garment with integrated sensors for continuous monitoring of physiological and movement related variables to evaluate progression, tailor treatments and improve diagnosis in epilepsy, Parkinson’s disease and stroke. Methods: An iterative development process and evaluation of an upper body garment with integrated sensors included: identification of user needs, specification of technical and garment requirements, garment development and production as well as evaluation of garment design, functionality and usability. The project is a multidisciplinary collaboration with experts from medical, engineering, textile, and material science within the wearITmed consortium. The work was organized in regular meetings, task groups and hands-on workshops. User needs were identified using results from a mixed-methods systematic review, a focus group study and expert groups. Usability was evaluated in 19 individuals (13 controls, 6 patients with Parkinson’s disease) using semi-structured interviews and qualitative content analysis. Results: A prototype designed to monitor movements and heart rate was developed. The garment was well accepted by the users regarding design and comfort, although the users were cautious about the technology and suggested improvements. All electronic components passed a washability test. The most robust data was obtained from accelerometer and gyroscope sensors while the electrodes for heart rate registration were sensitive to motion. artefacts. The algorithm development within the wearITmed consortium has shown promising results. Conclusions: The prototype was accepted by the users. Technical improvements are needed, but preliminary data indicate that the garment has potential to be used as a tool for diagnosis and treatment selection and could provide added value for monitoring seizures in epilepsy, fluctuations in PD and activity levels in stroke. Future work aims to improve the prototype further, develop algorithms, and evaluate the functionality and usability in targeted patient groups. The potential of incorporating blood pressure and heart-rate variability monitoring will also be explored.

Konferensbidrag (refereegranskat)abstract
- This case study reports the use of a new textile-electrode system for self-administered Phantom Motor Execution (PME) treatment at home in one patient with Phantom Limb Pain (PLP). In follow-up interviews, the patient reported reduced pain, increased mobility, and improved mental health, and aspects such as motivation, usability, support, and treatment outcome, could be recognized from an earlier study as crucial for successful implementation and adoption of the home-based long-term treatment. The findings are of interest to developers, providers, users, and researchers planning home-based clinical studies and/or scenarios based on technology-assisted treatment.

Using Smartphones to Monitor Cycling and Automatically Detect Accidents - Towards eCall Functionality for Cyclists
- 2014
-
Ingår i: Proceedings, International Cycling Safety Conference 2014. ; , s. 1-9
-
Konferensbidrag (refereegranskat)abstract
- Automatic crash notification to the nearest emergency center in case of a traffic accident will through the EU initiative eCall improve the safety for cars on European roads. eCall function- ality could also increase the safety for vulnerable road users such as cyclists, but there is no technical implementation agreed upon for this purpose. We propose to use smartphones due to their widespread availability and no need for extra hardware. Today’s high-end smartphones are equipped with both GPS functionality and movement sensors. The aims of this study were to explore if smartphones can be used to collect cycling data of sufficient quality and to design and evaluate a crash detection algorithm (CDA) for cycling accidents. A Google Nexus 4 smartphone was chosen for the study. This device is equipped with a combined accelerometer and gyroscope chip. Over five hours of “normal” cycling data, i.e. without accidents/incidents, was collected. Six crash tests were performed using a simplified crash test dummy. In order to achieve a realistic user scenario the smartphone was allowed to be easily carried as in everyday use, i.e. the users were not required to fix it to the body. We used the total acceleration based on the sum of square of each direction to obtain a measure independent on smartphone orientation. For normal cycling this measure was found to momentarily be as high as 50 ms−2. High levels were often due to handling of the smartphone. This prompted that an acceleration threshold alone is not sufficient for an accurate CDA. A marked rotation during a short time interval was found to be an important predictor for crashes. An accurate CDA was designed based on a combination of sensor data such as acceleration and rotation. The CDA detected all crashes and was subsequently evaluated in several hours of normal cycling without any false positive alarms.

Tidskriftsartikel (refereegranskat)abstract
- Abstract The theoretical framework is that muscle tension in the neck is related to insufficient muscular rest and is a risk factor for chronic pain and reduced work ability. Promoting muscle strength and muscle rest may increase work ability and reduce neck pain. Objectives To test whether myofeedback training or intensive strength training leads to decreased pain and increased work ability in women on long-term sick leave. Methods This is a randomized controlled trial of two 1-month interventions with myofeedback or muscular strength training in the home environment. Female human service organization workers (n = 60) on long-term (>60 days) sick leave and with chronic neck pain were followed with self-reported and laboratory-observed data of health, pain, muscular activation, and work ability, at baseline, immediately after the intervention and 3 months after baseline. Results For both intervention groups, pain was lowered over time compared with the control group. Decreased pain and muscular activity was associated with increased self-rated work ability and with laboratory-observed work ability at 3-month follow-up. Decreased pain was also associated with increased self-rated work ability at 1-month follow-up. Muscular strength training was associated with increased self-rated work ability and mental health. Myofeedback was associated with increased observed work ability and self- rated vitality. Conclusions The two interventions showed positive results, suggesting that they could be developed for use in health care practice to address pain and work ability. The intensive muscular strength training program, which is both easy to conduct at home and easy to coach, was associated with increased work ability.

‘Co-Creation’ is On Everyone’s Lips – Designers’ Perception of Opportunities For and Barriers To Co-Creation in Product Development Organizations
- 2022
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Co-creation, aimed at encouraging users to become active partners throughout the development process, has been widely discussed in academia for the last 10-15 years as a strategy for sustainable design of products that fulfil users’ needs and enhance users’ experience of future products. However, despite the fact that universities have undertaken to educate future designers on methods and tools for co-creation with users, we emphasize that there is still a noticeable gap between theory and practice, as designers’ opportunities for incorporating co-creation activities in product development organizations remain limited. The aim of this study, consisting of twelve semi-structured, in-depth interviews with design practitioners from Swedish industry, was to create a deeper understanding of the extent to which designers can and do actively involve users in the design process in industrial organizations. While we found that designers were interested and willing to work in a more user-centered way, there was no evidence of co-creation with users. The companies’ marketing departments were mainly responsible for customer/user contact, identifying and communicating user/customer requirements by means of traditional marketing methods. Hence direct communication between designers and users was rarely supported. Moreover, the informants often experienced a strong reluctance from the marketing department to provide them with necessary contacts, as this might interfere with their relationship with the customer. The barriers to accessing users were even more pronounced for designers in consultancy firms, where the customer functioned as the link to the market and frequently declined to allocate resources to user studies, arguing that they already possessed the necessary knowledge or that such studies were too costly. Consequently, irrespective of intra- or inter-organizational settings, designers’ ability to access users often depended on individual motivation and initiatives rather than organizational factors.

Tidskriftsartikel (refereegranskat)abstract
- This study analysed a series of workshops and explored prerequisites for interdisciplinary co-design among industrial designers, design engineers and users in the development of a novel medical device. Presented as a case study, this paper focus on what affects participants’ transformative processes towards genuine participation in co-design processes. Based on activity theory, we suggest that co-design activities have to support not only users, but all participants, shifting their perspectives beyond their own domain’s rules, motives, objects and division of labour, i.e., beyond their own activity system, to support users’ participation as equal members in design teams. We propose that genuine co-design requires a holistic approach where a neutral arena, an impartial facilitator, clear rules of play, along with representational artefacts as mediating tools in the formation of a new collective activity system to foster equality, mutual value and long-term knowledge generation. Such approach requires a process over time.

Product Representations as Mediating Tools in the Development of New Medical Technology
- 2018
-
Ingår i: Design4Health - Fifth International Conference on Design4Health.. - 9781843874218
-
Konferensbidrag (refereegranskat)abstract
- Involving users in the design process of new products and services is generally disputed as a prerequisite for fulfilling users' needs and requirements. The importance of user involvement has been argued also regarding the development of new medical technology. Collaboration between users and developers/designers is however not without problems due to differences in, e.g. background, training, perspective, and vocabulary. In order to address these differences, the need for different 'mediating tools' has been emphasized. One type of mediating tools is product representations (PRs). Earlier studies have most often focused on the type of PR that should be used in different phases of the development process in order to get input on different designs. This paper describes instead how and in what situations different PRs mediated communication and collaboration between professional users (medical experts) and designers in an innovation project targeting a solution for long-term monitoring of brain activity based on electroencephalographic (EEG) signals.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The number of 3D textile applications in medicine is rapidly increasing as new technology and procedures are introduced in health care. A first estimate of current medical applications of both general and 3D textiles is presented based on the medical devices classification system established by the US Food and Drug Administration. The textile specifics for these applications are covered from a textile technique perspective where the different 3D weaving as well as knitting, braiding and non-woven techniques are described and how their properties they can contribute in medical applications. In addition, emerging opportunities based on smart textiles as part of textile systems are described on a general level. The strong application areas of 3D medical textiles, i.e. wound management, vascular grafting and scaffolding for tissue engineering are covered in detail both from the medical and textiles perspective. Finally, some future lines of development are suggested and a short discussion on how new 3D textiles applications can be developed in close cooperation between the textile industry and the health care sector is presented.

Evaluation of a self-administered transcutaneous electrical stimulation concept for the treatment of spasticity: a randomised placebo-controlled trial.
- 2018

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Spasticity is a common consequence of injury to the central nervous system negatively affecting patient’s everyday activities. Treatment mainly consists of training and different drugs, often with side effects. There is a need for treatment options that can be performed by the patient in their home environment.AIM: The objective of this study was to assess the effectiveness of an assistive technology (AT), Mollii®, a garment with integrated electrodes for multifocal transcutaneous electrical stimulation intended for self-treatment of spasticity, in study participants with spasticity due to stroke or CP.DESIGN: The study was a randomized, controlled, double-blind study with a cross-over design.SETTING: Participants were recruited from two rehabilitation clinics. Treatments were performed in participants’ homes and all follow-ups were performed in the two rehabilitation clinics.POPULATION: Thirty-one participants were included in the study and 27 completed the study. Four participants discontinued the study. Two declined participation before baseline and two withdrew due to problems handling the garment.METHODS: Participants used the AT with and without electrical stimulation (active/non-active period) for six weeks each, followed by six weeks without treatment. Goal Attainment Scaling (GAS), change in mobility, arm-hand ability, spasticity and pain were measured at baseline and after 6, 12 and 18 weeks.RESULTS: Fifteen of the 27 participants fulfilled the treatment protocol in terms of recommended use. Deviations were frequent. No statistically significant differences in outcome were found between the active and the non-active treatment periods. During the active period, an improvement was seen in the 10-meter comfortable gait test, time and steps. An improvement was seen in both the active and non-active periods for the GAS.CONCLUSIONS: Compliance was low, partly due to deviations related to the garment, complicating the interpretation of the results. Further research should focus on identifying the target population and concomitant rehabilitation strategies.CLINICAL REHABILITATION IMPACT: The evaluated concept of multifocal transcutaneous electrical stimulation (TES) represents an interesting addition to the existing repertoire of treatments to alleviate muscle spasticity. The evaluated concept allows TES to be self-administered by the patient in the home environment. A more elaborate design of training activities directly related to patient’s own rehabilitation goals is recommended and may increase the value of the evaluated concept.

Systematic review of textile-based electrodes for long-term and continuous surface electromyography recording
- 2020

Forskningsöversikt (refereegranskat)abstract
- This systematic review concerns the use of smart textiles enabled applications based on myoelectric activity. Electromyography (EMG) is the technique for recording and evaluating electric signals related to muscle activity (myoelectric). EMG is a well-established technique that provides a wealth of information for clinical diagnosis, monitoring, and treatment. Introducing sensor systems that allow for ubiquitous monitoring of health conditions using textile integrated solutions not only opens possibilities for ambulatory, long-term, and continuous health monitoring outside the hospital, but also for autonomous self-administration. Textile-based electrodes have demonstrated potential as a fully operational alternative to 'standard' Ag/AgCl electrodes for recording surface electromyography (sEMG) signals. As a substitute for Ag/AgCl electrodes fastened to the skin by taping or pre-gluing adhesive, textile-based electrodes have the advantages of being soft, flexible, and air permeable; thus, they have advantages in medicine and health monitoring, especially when self-administration, real-time, and long-term monitoring is required. Such advances have been achieved through various smart textile techniques; for instance, adding functions in textiles, including fibers, yarns, and fabrics, and various methods for incorporating functionality into textiles, such as knitting, weaving, embroidery, and coating. In this work, we reviewed articles from a textile perspective to provide an overview of sEMG applications enabled by smart textile strategies. The overview is based on a literature evaluation of 41 articles published in both peer-reviewed journals and conference proceedings focusing on electrode materials, fabrication methods, construction, and sEMG applications. We introduce four textile integration levels to further describe the various textile electrode sEMG applications reported in the reviewed literature. We conclude with suggestions for future work along with recommendations for the reporting of essential benchmarking information in current and future textile electrode applications.

- Background: Welfare Technology (WT) can promote participation in activity. Thus, initiatives to support the implementation of WT products and services in municipality care settings needs to be developed and evaluated to benefit end-users. Objective: To evaluate an interactive showroom of WT. Material and method: Municipal employees (n = 217) filled in a questionnaire before and after they visited an interactive showroom of WT. Findings: The number of participants confirming WT’s potential to contribute to municipal operation areas increased in seven out of eight areas after their visits (p < 0.05). A statistically significant increase was also found regarding general knowledge of and confidence in WT and its potential value. Conclusion: A visit to the interactive showroom increased the perceived general knowledge and appreciated value of WT. The perception of the possibility of implementing WT in various municipal operation areas also increased, which may contribute to the implementation of WT in municipal care settings.

Tidskriftsartikel (refereegranskat)abstract
- Lack of user acceptance of telemedicine services is an important barrier to deployment and stresses the need for involving users, i.e. medical professionals. However, the involvement of users in the service development process of telemedicine services is difficult because of (a) the knowledge gap between the expertise of medical and technical experts; (b) the language gap, i.e. the use of different terminologies between the medical and the technical professions; and (c) the methodological gap in applying requirement methods to multidisciplinary scientific matters. We have developed a guideline in which the medical and technical domains meet. The guideline can be used to develop a scenario from which requirements can be elicited. In a retrospective analysis of a myofeedback-based teletreatment service, the technically-oriented People-Activities-Context-Technology (PACT) framework and medically-oriented principles of evidence-based medicine were incorporated into a guideline. The guideline was developed to construct the content of a scenario which describes the new teletreatment service. This allows the different stakeholders to come together and develop the service. Our approach provides an arena for different stakeholders to take part in the early stages of the design process. This should increase the chance of user acceptance and thus adoption of the service being developed.

- Objective: To explore patients’ experiences of a self-administered electrotherapy treatment for muscle spasticity in cerebral palsy and stroke; the Exopulse Mollii Suit®. Design: Qualitative design with an inductive approach Subjects: Fifteen patients with spasticity due to stroke or cerebral palsy, participating in a previous randomized controlled trial evaluating the treatment concept.Methods: Information letters were sent to all potential participants (n = 27) in the previous study. Semi-structured interviews (21–57 min) were carried out with all subjects who volunteered (n = 15), administered by an experienced interviewer who was not involved in the previous study. Transcribed interviews were subject to content analysis. Results: The 5 categories that emerged from the content analysis were “New method gives hope”, experiences related to “Using the assistive technology”, “Outcome from training with the assistive technology”, “The assistive technology” and “Taking part in the study”. Respondents felt hopeful when included in the previous study, motivated when experiencing a treatment effect, and disappointed when not. Conclusion: The qualitative approach used in this study elicited complementary information that was not evident from the previous randomized controlled trial. This included statements regarding increased mobility, reduced spasticity, reduced use of medication, and problems related to using the treatment concept.

Tidskriftsartikel (refereegranskat)abstract
- The present study investigates the dental work in terms of time distribution and mechanical exposure in value-adding work (VAW) and non-VAW. Further rationalisation of dental work would typically involve an increase in the proportion of VAW. Information on mechanical exposure within the classes of VAW and non-VAW may be used to predict possible implications of rationalisation. Sixteen dentists were investigated. Using a data logger, postures and movements were continuously recorded for each subject during the 4 h of work, which included the 45 min of video recording. Time distribution and mechanical exposure for the six different work activities identified were evaluated from the video recordings, using a loss analysis technique. VAW, which comprised 54% of the total working time, generally implied significantly more constrained mechanical exposures as compared with non-VAW. The results suggest that future rationalisation of dental work, involving a reduction of non-VAW, may increase the risk of developing musculoskeletal disorders.Statement of Relevance: The present study illustrates the potential effects of rationalisation on biomechanical exposures for dentists. The results highlight the significance of integrating ergonomic issues into the rationalisation process in dentistry in addition to ordinary workstation and tool design improvements performed by ergonomists.

- The aim of the present study was to test a structural model of the relationship between the perceived quantitative (time pressure and unevenly distributed workload) and emotional work demands and self-reported musculoskeletal symptoms from the neck and shoulder region with felt stress (rested, relaxed, calm, tense, stressed, and pressured at the end of a normal workday) as a mediating variable. As part of the NEW (Neuromuscular assessment in the Elderly Worker) study, a European case-control study, the present cross-sectional study was based on a questionnaire survey among Danish, Dutch, Swedish and Swiss female computer users aged 45 or older (n = 148). The hypothesized structural model was tested using structural equation modelling. The results indicate that perceived work demands influence neck/shoulder musculoskeletal symptoms through their effect on felt stress. The results further indicate complete mediation, which means that all of the effect of the perceived work demands on symptoms could be attributed to the stress mechanism. As regards the percentage of explained variance in the endogenous variables, 36% of the variation in felt stress was explained by the perceived work demands, and about 20% of the variation in musculoskeletal neck/shoulder symptoms was explained by the combination of the perceived work demands and the felt stress

Tidskriftsartikel (refereegranskat)abstract
- Introduction: It has been suggested that treatments may be more effective when they are matched to patient characteristics. This study aimed at investigating potential prognostic factors for clinically relevant improvement in symptom intensity and symptom-related disability among employees with symptoms in the neck/shoulder area, receiving either ergonomics counseling or such counseling in combination with myofeedback training. Methods: A randomized controlled study was performed among female computer users aged 45 or older (n = 36). A clinical examination and a questionnaire survey were performed before inclusion in the study. Symptom intensity and disability was assessed using questionnaires before the start of the interventions (baseline) and at follow-ups directly after the end of the interventions (T0) and after 3 (T3) and 6 (T6) months. Logistis regression analyses were performed in order to assess prognostic factors for clinically relevant improvement in symptom intensity and disability. Results: Improvement in symptom intensity was consistently predicted by symptom intensity at baseline. Diagnosis and stress-induced lack of muscular rest were prognostic factors for improvement in symptom intensity at short-term follow-up. Baseline disability and passive coping consistently served as prognostic factors for outcome in disability. Few substantial differences were found between the interventions in terms of prognostic factors. Conclusions: Myofeedback training in combination with ergonomics counseling seem to be an especially beneficial tool for secondary prevention among employees with moderate levels of symptom intensity and symptom-related disability, who respond to work-related stress by increased/sustained muscle activation, and who tend to employ passive coping to deal with their neck/shoulder symptoms.

- We investigated the potential prognostic factors for clinically relevant improvements in pain intensity and pain-related disability after myofeedback-based teletreatment. Sixty-five female computer users, 56 female patients with whiplash-associated disorders and 18 female patients with non-specific neck and shoulder pain participated in the study. They received myofeedback-based teletreatment or usual treatment. Questionnaires concerning prognostic factors, pain and disability were completed before the start of the intervention (baseline) and at follow-ups at the end of the intervention, and after 3 and 6 months. Logistic regression analyses were performed in order to investigate prognostic factors for clinically relevant improvement. In the intervention group, improvement in pain intensity was predicted by baseline pain intensity. Baseline pain intensity and disability, and fear-avoidance and endurance related pain coping responses were prognostic factors for outcome in pain-related disability in this group. Therewere few differences between the intervention groups; fear avoidance coping responses influenced the outcome after teletreatment only.Myofeedback-based teletreatment appears to be an useful telemedicine intervention, especially for participants with moderate to high levels of pain and disability, high perceived help/ hopelessness, and those who tend to deal with their pain by avoiding social and physical activities.

- Purpose Unfavorable psychosocial working conditions are hypothesized to lead to perceived stress, which, in turn, can be related to an increased risk of development of neck/shoulder symptoms through increased and sustained muscle activation. The aim of the present study was to test this hypothesized process model among medical secretaries, a female-dominated profession characterized by a high amount of visual display unit use and a high prevalence of neck/shoulder symptoms. Methods In this cross-sectional study, a questionnaire survey was conducted among medical secretaries (n = 200). The proposed process model was tested using a path model framework. Results The results indicate that high work demands were related to high perceived stress, which in turn was related to a high perceived muscle tension and neck/shoulder symptoms. Low influence at work was not related to perceived stress, but was directly related to a high perceived muscle tension. Conclusions In general, these cross-sectional results lend tentative support for the hypothesis that adverse psychosocial work conditions (high work demands) may contribute to the development of neck/shoulder symptoms through the mechanism of stress-induced sustained muscular activation. This process model needs to be further tested in longitudinal studies.

- The current study investigated the associations between work-related perceived stress and surface electromyographic (sEMG) parameters (muscle activity and muscle rest) during standardized simulated computer work (typing, editing, precision, and Stroop tasks). It was part of the European case-control study, NEW (Neuromuscular assessment in the Elderly Worker). The present cross-sectional study was based on a questionnaire survey and sEMG measurements among Danish and Swedish female computer users aged 45 or older (n=49). The results show associations between work-related perceived stress and trapezius muscle activity and rest during standardized simulated computer work, and provide partial empirical support for the hypothesized pathway of stress induced muscle activity in the association between an adverse psychosocial work environment and musculoskeletal symptoms in the neck and shoulder.

- Phantom Motor Execution (PME) is a mechanism-based approach for the treatment of Phantom Limb Pain (PLP), which could potentially be self-administered in the home environment. However, the placement of electrodes aimed to acquire myoelectric signals from the residual stump muscles can be regarded as a difficult and time-consuming process by the patient. Thus, to increase patient compliance, the process must be made easier, faster, and cost effective. In this study, we developed and investigated a seamless integrated textrode-band for myoelectric recordings. The textrode-band can be easily donned/doffed, is reusable and washable. We demonstrated the viability of such concept by analyzing the signal-to-noise ratio (SNR), as well as offline and real time motion decoding performance, that in our experience are compatible with the PME treatment.

- Adverse work-related physical exposures such as repetitive movements and awkward postures have negative health effects and lead to large financial costs. To address these problems, a multi-disciplinary consortium was formed with the aim of developing an ambulatory system for recording and analyzing risks for musculoskeletal disorders utilizing textile integrated sensors as part of the regular workwear. This paper presents the consortium, the Smart Workwear System, and a case study illustrating its potential to decrease adverse biomechanical exposure by promoting improved work technique.

- Lack of a shared language is a common communication situation in the globalizing world. Sometimes this can be mitigated by the use of machine translation technology, such as Google translate, but there are mission-critical tasks, like in health care, where one has to be sure about the correctness of the translation. In such situations, human interpreters are the best choice, but interpreters are scarce and in urgent situations they are not always available. This calls for improved and more reliable machine translation initiatives.The project to be presented is developing a mobile translator for ambulance personnel use. The translator uses a verifiable and controllable machine translation technology, which is based on semantics, grammars, and professional terminology. The technology has been developed in the international open source project Grammatical Framework (GF) and tested in numerous research projects as well as commercial applications. This project is the first one to apply GF in a healthcare setting. The aim is to develop a platform for a range of health care applications, provided this pilot project for ambulance/emergency care is successful.The translator works as a mobile app, in which the user can speak and write questions and other phrases, and get them translated to speech and text in other languages. The phrases cover the concepts used in the SBAR protocol (Situation-Bakgrund-Aktuellt tillstånd-Rekommendation) for ambulance use, as gathered from available documents and a questionnaire sent out to professionals at SU Ambulans. The SBAR protocol is also made available as a dynamic phrasebook, where the user can select appropriate phrases from menus. To help translate spontaneous speech and writing, the translator will also have a facility of suggesting nearest-matching phrases and ranking them by proximity to the verified standard phrases.The current prototype covers around 400 concepts, from which millions of phrases can be built. It will work for 7 languages and enable translation between any two of them, although the primary use case is translation from Swedish to another language and translating simple answers from the other language to Swedish. GF has potential for extending the application to over 30 languages.
