    Using Smartphones to Monitor Cycling and Automatically Detect Accidents: Towards eCall Functionality for Cyclists2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    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 functionality 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 ms2. 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.

    Myofeedback training and intensive muscular strength training to decrease pain and improve work ability among female workers on long-term sick leave with neck pain: a randomized controlled trial2011Inngår i: International Archives of Occupational and Environmental Health, ISSN 0340-0131, E-ISSN 1432-1246, Vol. 84, nr 3, s. 335-346Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    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.

    Three-dimensional multilayer fabric structures for interactive textiles2011Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Abstract. The integration of performances in interactive textile fabric system has so far been rather complicated since they are based on multilayer or three-dimensional principles. These structures are today mainly put together by means of several processes, which is laborious and time consuming. In this interdisciplinary study we have combined the principle of a three-dimensional multilayer weaving process and interactive textiles structures in order to enable the manufacturing of interactive textile structure in one process. The process is investigated using a manual reconstructed loom and the approach has been to use the 3D structures in order to integrate and organize conductive and compressive spacer layers as a textile capacitive structure. Measurements on such a structure was done by construction a first order passive high pass filter and using the fabric sample as the capacitor and a 1MΩ resistor. The behavior of the measurement of the capacitive sensor is quite close to the theoretical calculation and already at this stage the structure might be used to indicate the presence of a pressure. In this project we have shown that a three-dimensional structure enables the development of interactive textiles in one process. Further the concept of using a rebuilt manual loom has shown great potential in early research stages. It is considerable saving time and resources since, in this case, it is easy to reconstruct the loom design compared to performing similar reconstruction on a machine. Future research will focus on developing other types of interactive structures. Another issue will be to scale down the size of the structures in order to get thinner and more flexible qualities.

    Tredimensionell vävteknik med möjliga tillämpningar inom medicinsk teknik2011Konferansepaper (Annet vitenskapelig)
    Abstract [sv]

    Integreringen av interaktiva egenskaper i teknisk textil har rönt stort intresse inom textil-forskningen de senaste åren. Med interaktiva textila strukturer avses textila system som interagerar med sin omgivning i någon mening. Ett sätt att åtadkomma dessa interaktiva strukturer är att foga samman lager av olika struktur eller material där varje lager tillför textilen/det textila systemet olika egenskaper. Det typiska tillvägagångssättet för att sammanfoga olika lager av textila material är att använda någon form av lamineringsteknik. Föreliggande projekt rör en ny vävteknik som möjliggör att flera textila lager med olika egenskaper vävs samman i en och samma process utan de tillsatser eller extra hantering som krävs vid laminering. Utöver de uppenbara produktionstekniska fördelarna möjliggör kombinationen av olika egenskaper i en lagerstruktur också att speciella krav på slutprodukten lättare kan tillgodoses. Det medicintekniska området förväntas ha stor nytta av textila strukturer som kan utformas i tre dimensioner eller kombinera olika egenskaper i en och samma struktur. Syftet är att demonstrera hur en nyutvecklad vävteknik för tredimensionella strukturer kan tillämpas för att tillverka interaktiva textila strukturer i en och samma tillverkningsprocess. I detta delprojekt har den tredimensionella tekniken använts för att utveckla en kapacitiv struktur utformad helt i textil. Genom mindre modifieringar av och tillägg till en 16-skaftad datorstyrd manuell prototypvävstol har två ledande och ett isolerande skikt kombinerats för att realisera en textilbaserad kondensator. I ett första test realiserades ett enkelt högpassfilter med den kapacitiva textila strukturen som kondensator. Filtrets egenskaper visade sig väl följa den förväntade filterkarakteristiken. Den nyutvecklade tredimensionella vävtekniken förväntas ha stora tillämpningsmöjligheter inom det medicintekniska området.

    Ambulance Personnel Participating in Co-Design of a New Concept for Detection of Traumatic Injuries in Emergency Care2016Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    BACKGROUNDStudies in product development argue the importance of user involvement when designing products. Benefits include targeting relevant problems, finding usable and innovative solutions, and elicit user needs and expectations that may prove critical when introducing the new product.

    However, some difficulties have been identified. These are mainly related to differences between the users and developers in terms of skills, experiences, terminology, goals and perspectives and that the users tend to neglect the value of their input. Typically users are also included too late in the process to have any real opportunities to alter the final product.

    The aim of this study was to explore how early inclusion of user competence might influence the development of a novel concept for detection of traumatic injuries in emergency care.

    METHODSAmbulance nurses representing car and helicopter ambulance were invited to three consecutive workshops to co-design key products of the new concept together with development personnel from the company behind the new concept and design researchers/engineers. The workshops were held in the ideation, concept generation, and development stages of the project. Each workshop was prepared by the researchers to enable and stimulate interaction within the group by applying design practices and provide mock-ups/illustrations. 

    RESULTS Preliminary results from interviews tell that the company representatives report more detailed knowledge about the ambulance personnel’s needs earlier in the process compared to previous projects, and that this knowledge contributed to products with higher usability.

    The ambulance personnel were positive and pleased to contribute their knowledge. One response was “it is very interesting to contribute to the development of a future product”.

    CONCLUSIONSThe tested co-design process facilitated the ambulance nurses to contribute their knowledge so that needs and requirements was understood and integrated by the engineers in the design of the new concept for emergency care.

    Three-dimensional Fabrics as Medical Textiles2015Inngår i: Advances in 3D Textiles: A volume in Woodhead Publishing Series in Textiles / [ed] X. Chen, Woodhead Publishing Limited, 2015, s. 305-340Kapittel i bok, del av antologi (Annet vitenskapelig)
    Abstract [en]

    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.

    Facilitating User Involvement in Development of 3D Smart Textiles For Healthcare Applications2015Inngår i: Proceedings of the 6th World Conference on 3D Fabrics and their Applications, Manchester,UK/Raleigh,USA, 2015Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Smart textiles are textiles based on different types of smart materials that can sense or react on environmental stimuli. This new technology is a growing area which exhibits characteristics particularly suitable for capturing (electro) physiological signals, e.g. to monitor ECG, EEG or respiration. These textiles most often form a three dimensional structure where different materials with different characteristics are bound together in different layers. However, in order to take full advantage of these new opportunities the textile industry needs to find new methods to develop innovative smart textile products. One strong and valuable contribution is to involve users early in the development process.

    The aim of this paper is to highlight how product representations, e.g. prototypes or material samples, can be used to facilitate the communication between users and developers in the development of new healthcare solutions based on textiles. The study presented in this paper was performed through participatory observation. The case is based on the development of a textile structure with three dimensional properties for long-term monitoring of EEG signals.   

    The main findings are that product representations support the exchange of knowledge and experiences between users and developers by five different facilitating roles:

    Product representations serve to demonstrate (technical) solutions; to verbalise, i.e. serve to fill in were words are missing or when terms are not understood; to visualise, i.e. facilitating members of the development team to envision or adapt mental images of the intended future product; to stimulate, i.e. to inspire the development team to suggest new ideas or design; and, finally, to integrate, i.e. to unite different perspectives within the development team.

    Conclusion: By using product representations during the development process to facilitate the dialogue between users and developers, the textile industry may take full advantage of the opportunities made available by new development of materials and new technology in order to fulfil users’ needs.

    Product Representations as Mediating Tools in the Development of New Medical Technology2018Inngår i: Design4Health - Fifth International Conference on Design4Health.: Proceedings of the 5th International Conference on Design4Health, Sheffield, UK, 4–6 September 2018. / [ed] Kirsty Christer, Claire Craig & Dan Wolstenholme, 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    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.

    Evaluation of a self-administered transcutaneous electrical stimulation concept for the treatment of spasticity: a randomised placebo-controlled trial.2018Inngår i: European Journal of Physical and Rehabilitation Medicine, ISSN 1973-9087, E-ISSN 1973-9095, Vol. 54, nr 4, s. 507-17Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    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.

    3D Composite Textile Characteristics Relevant in Pressure Ulcer Management2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    INTRODUCTION

    Effective ulcer management requires the wound to be in a moist but still breathable environment, to facilitate healing, absorb exudates and prevent maceration. One of the applicable methods to achieve this is the use of composite dressings. Most composite dressings are made of three layers to provide absorption and a bacterial barrier in a non- or semi-adherent cover. Various common textile materials such as cotton, polyester, polypropylene and cellulose can be used as different layers in those wound dressings. In addition to these established dressings, electrical stimulation therapy may be used in treating ulcers. It has been reported that electrical stimulation can reduce the area and depth of the wound in a shortened time compared to conventional treatment. In summary, encouraging wound healing results have been obtained both from using composite wound dressing and from applying of electrical stimulation. The aim of this study is to present a conceptual design based on a woven 3D structure that combines the composite wound dressing properties with electrical stimulation for pressure ulcers healing/management.

    METHOD

    In the suggested structure, different layers in X, Y and Z led were designed with different materials for different purposes.  The top layer consisting of a low-density web to provide a non-adherent layer combined with two textile electrodes made of conductive threads, the middle layer contributes pressure release and absorption of exudates, and the bottom layer next to the wound for moisture keeping while still allowing adequate ventilation.

    Two key properties were addressed in the study: pressure release and the possibility to provide electrical stimulation of the wound. Simulation with COMSOL Multiphysics was used to study pressure distribution according to Hertz contact theory. The surface resistance of the electrodes were also studied using in-house designed four-point measurement probes.

    RESULTS

    The simulation results show the composite structure to exhibit good pressure release properties. Surface resistance testing proved that the textile electrodes have resistance in the magnitude of 102 indicating that textile electrodes can be used for electrical stimulation in ulcers healing.

    The first results from this study demonstrate the feasibility to design a textile system combining established composite dressings solutions with means for electrical stimulation based on 3D weaving technique to be applied in pressure ulcer healing.

    Surface Resistivity of Textile-Based Electrodes2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Textile-based electrodes show great potential as substitution of conventional electrodes when long-time monitoring is required. The flexibility and high skin-electrode contacting area make it possible to avoid the use of contact gel, which may cause irritation to the patients' skin. In this study, textile-based electrodes were made by combining conductive materials with high absorption nature fibres with the intention to create and maintain a microenvironment that improve the contact between the skin and electrode by local sweating at the electrode site. Alternatively artificial sweat (i.e. saline) may be added for a similar effect. However, by adding nature fibres into the electrodes, the electrical properties of the electrodes are modified due to the ration of conductive yarns is decreased. In this paper, the surface resistivity in the warp and weft directions and its distribution were measured in a four-wire resistance mode. The resistivity of the conductive yarns, the type of nature fibres, the textile construction and the fabric pick density were selected as the independent variables and the surface resistivity in warp and weft measurement directions was the dependent variable to be analysed. Preliminary results show that the conductivity of the conductive yarns are more important than the fabric pick density; surface resistance were not measurable in warp direction of most plain weave fabrics since the conductive yarns were only involved in the weft direction, however, the resistance were measureable in the case of satin fabrics; and that the surface resistivity is more evenly distributed in weft direction than the warp direction

    Disappearing sensor: Textile based sensor for monitoring breathing2011Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The monitoring and interpretation of respiration pattern plays an important role for the early detection and the prevention of serious illness, such as asthma, sleeping apnea, bronchitis, and lung cancer. In this interdisciplinary project a system based on a smart shirt with integrated textile sensor for personal respiratory monitoring was developed. Due to the fact that textile products are flexible, washable and bring no discomfort to wearers, the smart shirtis an excellent interface for performing long term respiratory monitoring in real life situations outside the clinic. Two stripe liked sensors located on the chest and abdomen position respectively were integrated in a smart shirt. The sensors were made by coating with conductive silicone on the fabric surface of the smart shirt. Conductive silicone reflects compression or extension by resistance change and in this application resistance change can be utilized to indicate the respiratory pattern of the wearer. A prototype system was made to record the resistance change in real time and transmission to a PC or PDA for further processing. Snap button and conductive threads were used as the interface and transmission wires between the smart shirt and the recording system. To verify the performance, test were made with 10 subjects, whose spontaneous respiratory patterns were recorded during sitting still, walking and jogging. In addition, a number of abnormal respiratory conditions, such as deep breathing, hyperventilation and sleeping apnea were simulated. The results show the smart shirt performed in a very good manner, the system can sense and record the person's breathing during normal daily activities. The sleeping apnea simulation indicates potential application in diagnosis and clinical treatment. The smart shirt is soft and comfortable to use and enables long-term monitoring to be performed outside the laboratory.

    A scenario guideline for designing new teletreatments: a multidisciplinary approach2010Inngår i: Journal of Telemedicine and Telecare, ISSN 1357-633X, E-ISSN 1758-1109, Vol. 16, nr 6, s. 302-307Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    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.

    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.

    Mechanical exposure among general practice dentists in Sweden and possible implications of rationalisation2011Inngår i: Ergonomics, ISSN 0014-0139, E-ISSN 1366-5847, Vol. 54, nr 10, s. 953-960Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    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.

    Rationalisation in public dental care: Impact on clinical work tasks and mechanical exposure for dentists - a prospective study2013Inngår i: Ergonomics, ISSN 0014-0139, E-ISSN 1366-5847, Vol. 56, nr 2, s. 303-313Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Swedish dentistry has been exposed to frequent rationalisation initiatives during the last half century. Previous research has shown that rationalisation often results in increased risk of developing work-related musculoskeletal disorders, thus reducing sustainability in the production system. In this prospective study, we assessed mechanical exposures among Swedish dentists in relation to specific rationalisations of clinical dental work during a six-year period. Body postures and movements of 12 dentists were assessed by inclinometry synchronised to video recordings of their work. No rationalisation effects could be shown in terms of a reduction in non-value-adding work ('waste'), and at job level, no major differences in mechanical exposure could be shown between baseline and follow-up. CONCLUSION: The present rationalisation measures in dentistry do not seem to result in rationalisation at job level, but may potentially be more successful at the overall dental system level. PRACTITIONER SUMMARY: In contrast to many previous investigations of the mechanical exposure implications of rationalisation, the present rationalisation measures did not increase the level of risk for dentists. It is highlighted that all occupations involved in the production system should be investigated to assess production system sustainability.

    Prognostic factors for the effect of a myofeedback-based teletreatment service2010Inngår i: Journal of Telemedicine and Telecare, ISSN 1357-633X, E-ISSN 1758-1109, Vol. 16, nr 6, s. 336-343Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    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. There were 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.

    Psychosocial work conditions, pereived stress, perceived muscular tension, and neck/shoulder symptoms among medical secretaries2013Inngår i: International Archives of Occupational and Environmental Health, ISSN 0340-0131, E-ISSN 1432-1246, Vol. 86, nr 1, s. 57-63Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    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.

    Abstract [en]

    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.

    A Mobile Language Interpreter App for Prehospital/Emergency Care2017Inngår i: Medicinteknikdagarna 2017, 2017Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    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.

    Working conditions, health and productivity among dentists in Swedish public dental care: a prospective study during a 5-year period of rationalisation2013Inngår i: Ergonomics, ISSN 0014-0139, E-ISSN 1366-5847, Vol. 56, nr 9, s. 1376-1386Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In recent decades, comprehensive rationalisations have been implemented in public dentistry in Sweden. How rationalisations affect working conditions, health and production from a long-term perspective has been poorly investigated. This study aims to analyse changes and associations in dentists' working conditions, health and productivity during a 5-year period. In 2003 and 2008, 65 dentists responded to questionnaires measuring work conditions and health. Treatment times for patients and productivity were tracked in electronic registers. Paired t-tests showed that the number of treated adult patients per dentist increased, and perceived physical working conditions improved while perceived work control and leadership deteriorated. Structural equation modelling showed that physical factors were important for health and productivity. When assessing risks in the work environment, there is a need to understand the interaction of effects on working conditions and health due to rationalisations so as to increase the sustainability of production systems. PRACTITIONER SUMMARY: Dentistry in Sweden has undergone considerable change. Questionnaire surveys with dentists, undertaken in 2003 and 2008, found that the present rationalisations resulted in improved perceived physical working conditions. Aspects of the psychosocial working environment had deteriorated, however. This is a concern as health and workability are important for workplace efficiency.

    Vulnerable Road Users: An eCall service for two-wheel vehicle users2015Rapport (Fagfellevurdert)
    Abstract [en]

    Vulnerable road users (VRUs) make up an increasing proportion of killed and severely injured in road traffic accidents. A way of reducing the consequences of road traffic accidents is to make efforts to reduce the time to find the crash site and perform appropriate rescue actions. Automatic Crash Notification (ACN) systems have been developed during the last two decades and are now featured in many modern cars. The European eCall initiative makes an automatic emergency call–function mandatory in all new cars introduced to the European market from 2017.

    The aim of this pre-study was to investigate the possibilities and the potential value of implementing an eCall functionality for VRUs with special focus on two-wheelers and bicyclists.

    This pre-study found a few existing products and services related to the ACN/eCall concept aimed at VRUs, but that there is still a vast potential for further initiatives and development. A pilot study performed as part of this pre-study demonstrated that smartphone technology can be used to detect an accident/fall and in addition also may provide information on the impact experienced by the VRU. Further, that this information can contribute significantly to the postcrash rescue activities and this way reduce the accident-related consequences to the individual.

    Clinical evaluation of a myofeedback-based teletreatment service applied in the workplace: a randomized controlled trial2010Inngår i: Journal of Telemedicine and Telecare, ISSN 1357-633X, E-ISSN 1758-1109, Vol. 16, nr 6, s. 329-335Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We evaluated the clinical effects of a myofeedback-based teletreatment service in terms of pain, pain-related disability and work ability. We also investigated the time investment/savings of this treatment with respect to conventional care. Sixty-five women with neck and shoulder pain at work participated in the study. Thirty-three took part in the teletreatment and 32 participated in a control group which continued with conventional care. Questionnaires were completed before the start of the intervention (baseline) and at initial follow-up (T0) and 3 months (T3) after the intervention ended. A general linear model analysis for repeated measurements showed an improvement in terms of pain and work ability for both groups taken together, with no differences between them. Non-parametric tests showed an intervention effect in pain-related disability for both groups together and no differences between them when tested at baseline, T0 and T3. The time saved in relation to conventional care was mainly from reduced travel time, which was 41 min per teleconsultation. The teletreatment service allowed employees to take part in muscle relaxation training while performing their regular work. The clinical evaluation showed that the treatment was on par with conventional care, but without the effort and time loss associated with regular visits to the clinic. We conclude that the myofeedback-based teletreatment service has potential for addressing neck and shoulder symptoms at the workplace.

    A Concept for Naturalistic Data Collection for Vulnerable Road Users Using a SmartPhone-based Platform2015Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    This paper presents a smartphone-based platform for large-scale, low-cost, long-term naturalistic data collection aimed at vulnerable road users (VRUs). The approach taken is to collect naturalistic movement data from VRUs based on information from the embedded sensors in high-end smartphones. The Smartphone application, LogYard, developed in the current study, allows the recording of high quality data (tri-axial acceleration and rotation at 100 Hz plus GPS position and velocity each second). This way, large data quantities from ATV drivers’ movements during daily use in different use cases, can be transferred from a large number of users and accumulated in a cloud-based server for off-line analysis.

    Apart from the description on how data is recorded and managed in the smartphone-based platform, also a procedure on how to include participants to studies and how private integrity issues and informed consent can be handled from a distance is presented.

    By means of the presented smartphone based platform, large number of participants taking part in several parallel on-going studies can be easily administered. This makes the platform a powerful tool to use in large-scale, low-cost, long-term studies providing data from large groups of study participants.

    The information made available this way can be used to develop automatic crash notification (ACN) systems directed to VRUs based on identifying movements outside what is “normal” for bicyclists, mopedists, motorcyclists and ATV users.
