    Förändras neuromuskulärkontroll vid funktionella aktiviteter hos personer med icke-specifik ländryggssmärta?: En pilotstudie2020Independent thesis Basic level (professional degree), 180 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Ländryggssmärta är en av de diagnoser folk söker mest vård för i västvärlden och cirka 80% av alla vuxna kommer någon gång i livet drabbas av det. Primära orsaken är icke-specifik, det vill säga, att man inte vet vad som ligger bakom. Tidigare elektromyografi studier har visat att personer med icke-specifik ländryggssmärta kan utveckla förändrade muskelaktiveringsmönster för bålmuskulaturen. Till skillnad mot tidigare studier riktar denna sig till vardagliga aktiviteter där forskning i nuvarande läge lider brist Syfte: Syftet med studien var att undersöka aktiveringsmönster av bålmuskulaturen med hjälp av yt-EMG bland studenter vid utförande av funktionella aktiviteter. Metod: Två deltagare delades in i två grupper, en med icke specifik ländryggssmärta och en utan symtom. Tre funktionella tester utfördes med yt-EMG mätning av muskelaktivitet i bålen vid ett tillfälle. EMG amplituden beräknades med root mean square (RMS). Deltagarna fick skatta sin smärta på visual analogue scale (VAS) samt värdera sin upplevda funktion med Oswestry disability index (ODI). Resultat: Större muskelaktivering i erector spinae (ES) hos deltagaren med besvär jämfört med deltagaren utan besvär. Aktiveringsgraden hos lumbala multifidus (LMF) hade deltagaren utan besvär en större aktivering jämfört med deltagaren med besvär. Deltagaren med besvär hade 2-5 gånger större aktivering i främre bålmuskulatur i alla tester. Konklusion: Då studien är en pilot-studie med begränsat antal deltagare ses resultaten som preliminära indikationer. Framtida större studier kan ge svar på om och på vilket sätt neuromuskulära kontrollen påverkas vid vardagliga aktiviteter, dock är resultaten i studien i stora drag överensstämmande med tidigare studier.

    Climate change and human behaviour: Understanding modal choice in a rapidly urbanising Arctic2019Conference paper (Other academic)
    Abstract [en]

    This poster explores the human dimension of non-motorised transport, i.e. soft-mobility in Arctic communities. Empirical results are used to show how people’s modal choice in the European Arctic is being influenced by climate evolution and human-made climate change. From these results, it is possible to conceive new visions of the how to design the outside environments of Arctic settlements that can better enable people to move around in Arctic communities with reduced reliance on vehicles. At the societal level, this research will help reduce energy consumption and pollution from transport.

    The Effect of Kinesiotape on Flexion-Extension of the Thoracolumbar Back in Horses at Trot2020In: Animals, ISSN 2076-2615, E-ISSN 2076-2615, Vol. 10, no 2, article id 301Article in journal (Refereed)
    Abstract [en]

    Kinesiotape theoretically stimulates mechanoreceptive and proprioceptive sensory pathways that in turn may modulate the neuromuscular activity and locomotor function, so alteration of activation, locomotion and/or range of motion (ROM) can be achieved. The aim of this study was to determine whether kinesiotape applied to the abdominal muscles would affect the ROM in flexion-extension (sagittal plane) in the thoracolumbar back of horses at trot. The study design was a paired experimental study, with convenient sample. Each horse was randomly placed in the control or the intervention group and then the order reversed. Eight horses trotted at their own preferred speed in hand on a straight line, 2 × 30 m. Optical motion capture was used to collect kinematic data. Paired t-tests, normality tests and 1-Sample Wilcoxon test were used to assess the effects of the kinesiotape. No statistical significance (p < 0.05) for changes in flexion-extension of the thoracolumbar back in trot was shown in this group of horses. Some changes were shown indicating individual movement strategies in response to stimuli from the kinesiotape. More research in this popular and clinically used method is needed to fully understand the reacting mechanisms in horses.

    Organizing for sustainable inter-organizational collaboration in health care processes2020In: Journal of Interprofessional Care, ISSN 1356-1820, E-ISSN 1469-9567, Vol. 34, no 2, p. 241-250Article in journal (Refereed)
    Abstract [en]

    Integrating health care services has proven to be important from both the patient and organizational perspectives. This study explores what defines a perceived well-functioning collaboration in the inter-organizational process of providing assistive devices in Sweden. Two focus groups comprising participants with profound knowledge of collaboration were performed, and data were analyzed in five steps, resulting in a data structure. Results yield the identification of three interacting processes: coordinating efforts to patient needs, ensuring evidence-based practice, and planning for efficient use of resources. These processes affected one another, and, therefore, would likely not have been effectively managed separately. The study contributes to theories of process management and organization by specifically focusing on how to analyze and improve sustainable collaboration in health care processes at both the management and professional levels. Theoretical frameworks that show different ways of organizing collaboration, as well as the concepts of action nets and boundary objects, can support both analysis and planning of collaboration. The intention would be to develop integration in inter-organizational health care processes, resulting in more person-centered care.

    Perceived impact of meteorological conditions on the use of public space in winter settlements2020In: International journal of biometeorology, ISSN 0020-7128, E-ISSN 1432-1254, Vol. 64, no 4, p. 631-642Article in journal (Refereed)
    Abstract [en]

    This study aimed to assess the impact of meteorological conditions on the use of public space in Scandinavia and Canada. Between September 21 and December 18, 2017, a cross-sectional online survey ‘EAMQ-Climate: space’ was distributed via web-based platforms. Survey responses were received from 361 residents (258 people from Scandinavia and 103 from Canada). The relative impact of the meteorological determinants on the use of public space was calculated, and a factor analysis was performed. Disparities between Canada and Scandinavia as well as between the climate zones represented were analysed using ANOVA. Overall results showed that the most significant meteorological enablers for the use of outdoor public spaces in winter were solar gain, snowfall and snow-covered surfaces. The main barriers were slush-covered and icy surfaces, rainfall and darkness. Wind and cold were conditions with less influence. The impact of rain and ice, however, differed between climatic zones. It was also established that, when addressing the meteorological impact on avoiding the use of public spaces in winter, it is vital to discriminate between conditions related to a) the ground surface and b) ambient conditions, as well as the particular significance of c) snow and sun, and d) darkness. For the design of public space in winter cities, we conclude that designers need to focus on a wider range of weather conditions than sun, wind and cold, and include snow, rainfall, slushy and icy ground and poor visibility. The study suggests that winter public space has a higher climatic design requirement to be successful than streets and pathways that are mainly used for soft mobility.

    Young Migrants’ Experiences and Conditions for Health: A Photovoice Study2020In: SAGE Open, ISSN 2158-2440, E-ISSN 2158-2440, Vol. 10, no 2Article in journal (Refereed)
    Abstract [en]

    Visualization and expression of health-related experiences and conditions by young migrants from five different countries residing in Sweden were examined in this study. Using photovoice, the participants were invited to describe and discuss their experiences in three stages: (a) document and portray their everyday lives by taking pictures, (b) discuss their findings, and (c) present their views on health to the adults who are present in their everyday life and that are important for improving young migrants’ health conditions. The overall findings indicate that temporal, spatial, and social conditions are important for the well-being of these young migrants. Thus, in order for the young migrants to feel well in a new cultural context, a search for meaning and meaningfulness in relation to time, place, and other people was important. These findings are discussed in light of social, mental, and existential health dimensions and in relation to the selected study methods.

    Everyday activities outside the home are a struggle: Narratives from two persons with acquired brain injury2020In: Scandinavian Journal of Occupational Therapy, ISSN 1103-8128, E-ISSN 1651-2014, Vol. 27, no 3, p. 194-203Article in journal (Refereed)
    Abstract [en]

    Background: Participation restriction is a common consequence after acquired brain injury (ABI).

    Aim: To explore and identify problematic situations in everyday activities outside the home for persons with acquired brain injury.

    Material and Method: Two persons of working age with ABI were included. Data were generated through repeated semi-structured interviews and participant observations. Narrative analysis was used to capture ongoing processes related to problematic situations during engagement in everyday activities outside the home.

    Results: The narratives reflect how places, everyday activities and social relations were closely connected and influenced engagement in everyday activities outside the home. The participants visited fewer places and performed more of their everyday activities alone in their homes after the injury compared to before. They were struggling to create meaning in their lives and trying to reformulate their identity. Problematic situations often occurred outside the home as a result of unexpected events. The narratives indicate a struggle to find new routines to handle challenging situations.

    Conclusions: The results provide an understanding of how problematic situations occurred and were managed in different ways. By observing everyday situations professionals can gain access to how persons with ABI act in and reflect upon problematic situations which can eventually improve the design of individually tailored interventions.

    Sitting postures’ effects on movement behavior and musical performance among high string musicians – a pilot study2018In: Musicians' Health and Performance 3rd Conference 2018 (MHPC2018), Helsinki, 2018Conference paper (Other academic)
    Abstract [en]

    The posture has a major influence on the body; e.g., a slumped posture can lead to increased tissue loading but also altered movement behavior. Musicians, including violinists/violists, have a high prevalence of upper body musculoskeletal disorders. Biomechanical risk factors include repetitive movements, altered muscle activation and awkward postures. Changes in posture may have implications for both injury risk and the musical performance. Ideally, a healthy posture leads to the desired qualities of the performance, but this is still to be investigated. This multidisciplinary study takes an initial step to unravel the impact on both movement behavior and musical quality related to playing posture among high string musicians.

    To be seen as a unique person after suffering a second myocardial infarction: Expressed needs of patients and descriptions of personnel2020In: Intensive & Critical Care Nursing, ISSN 0964-3397, E-ISSN 1532-4036, Vol. 57, article id 102797Article in journal (Refereed)
    Abstract [en]

    Objectives

    The aim of this study was to describe patients’ expressed needs during cardiac rehabilitation after suffering a second myocardial infarction in comparison to personnel’s descriptions of how they work with these patients.

    Research methodology

    A descriptive qualitative design. Interviews were conducted with patients affected by two myocardial infarctions and registered nurses, physiotherapists and cardiologists working with cardiac rehabilitation. Data were analysed with qualitative content analysis.

    Findings

    An interpretation of the underlying meaning in the categories was formulated into one theme: ‘To be seen as a unique person’. Patients expressed a need for individualised care; they wanted the cardiac rehabilitation to be customised to their condition and prognosis; however, they did not perceive their care was individualised. Personnel described the importance of the care being individualised, although they had guidelines to follow. It was crucial for them to see the individual and discover what was important for each patient.

    Conclusions

    There was a shared opinion from patients and personnel that individual care is essential. Using the concept and working in accordance with person-centred care could meet the patients’ need for individualised care.

    MTHFR, TYMS and SLCO1B1 polymorphisms and adverse liver effects of methotrexate in rheumatoid arthritis2020In: Pharmacogenomics (London), ISSN 1462-2416, E-ISSN 1744-8042, Vol. 21, no 5, p. 337-346Article in journal (Refereed)
    Abstract [en]

    Aims: To investigate whether variants of MTHFR, TYMS and SLCO1B1 are associated with alanine aminotransferase (ALT) elevation in rheumatoid arthritis patients starting methotrexate (MTX).

    Patients & Methods: Clinical and laboratory data were collected from the start of MTX treatment. Genotyping of MTHFR, TYMS and SLCO1B1 was performed. Univariate and multiple logistic regression were used for statistical analysis.

    Results: 34 out of 369 patients experienced ALT >1.5xULN less than 6 months from start. MTHFR A1298C (rs1801131) was nominally associated with an ALT > 1.5 xULN within 6 months after the start of MTX (OR = 1.7 [95% CI: 1.04–2.9]; p = 0.03), but did not pass correction for multiple testing. A multiple model containing MTHFR 1298C and clinical factors predicted the outcome (C-statistic 0.735). TYMS and SLCO1B1 were not associated with the outcome.

    Conclusions: A model containing MTHFR 1298C and clinical factors might predict risk of early ALT elevation.

    Arbetsterapeuters erfarenheter av digitalisering: möjligheter och utmaningar2020Independent thesis Basic level (professional degree), 180 HE creditsStudent thesis
    Abstract [en]

    Aim: The aim of this study was to describe occupational therapists' experiences of the importance of digitalization for the profession with its opportunities and challenges in different areas of activity. Method: 9 semistructured interviews were conducted with occupational therapists and collected data were analyzed with a qualitative content analysis.Results: The impact of digitalization on occupational therapists’ day-to-day work presents many opportunities but also challenges. Everyday technology influences and changes the administrative work, client meetings and also the organizational work. A consequence is also an affected work environment. Sometimes risks are also seen in relation to digitalization. The conditions for using everyday technology in the profession vary among the occupational therapists. It comes to access to or lack of resources such as equipment, time and skills. There is usually access to technical support but the occupational therapists see an upcoming need for competence development, also in order to be updated along with the client. Conclusion: The study shows occupational therapists' experiences of the importance of digitalization for the profession with its opportunities and challenges in different areas of activity. The study shows that digital competence is and will be a prerequisite for the day-to-day work of the occupational therapist. Furthermore, the study shows that a good working digitalization requires resources and also critical thinking. There is a need for further research in the field as there are currently few studies that illustrate the importance of digitalization for occupational therapists.

    Potential effects of long term abuse of anabolic androgen steroids on human skeletal muscle2020In: Journal of Sports Medicine and Physical Fitness, ISSN 0022-4707, E-ISSN 1827-1928Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: We have previously evaluated muscle functions and morphology in power athletes of long term (5 to15 years) abuse of anabolic androgen steroids (AAS; Doped) and in clean power athletes (Clean), and observed significant improvements in both muscle morphology and muscle functions in Doped. To our knowledge, the effects of long term AAS abuse on human muscle protein profile have never been studied.

    METHODS: The study examined further the muscle biopsies using a two-dimensional difference gel electrophoresis (2D DIGE) for proteomic screening and protein expression. Cellular localization/distribution of specific proteins identified by proteomic analysis was examined using immunohistochemistry (IHC).

    RESULTS: Different protein profiles were observed between Doped and Clean, and a valid orthogonal projection of latent structure discriminant analysis model was built (N = 16, X = 5, R2 = 0.88/Q2 = 0.84, p = 0.0005), which separated Doped from Clean. Liquid chromatography followed by tandem spectrometry identified 14 protein spots (representing nine different proteins) of significant difference in relative quantity (p < 0.05), of which nine spots were down-regulated in Doped compared with Clean. IHC revealed no significant alteration in cellular localization in phosphoglucomutase-1 and heat shock protein beta-1, but indeed in two reference proteins desmin and F-actin in Doped.

    CONCLUSIONS: Long term abuse of AAS in combination with training is potentially associated with alterations in skeletal muscle protein profile and protein expression, and structural proteins rather than non-structural proteins are preferentially affected in cellular localization/distribution.
