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.

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.

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.

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.

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.
