    Solar energy studies and extramural learning2003In: ISES Solar World Congress, 2003Conference paper (Refereed)
    Abstract [en]

    Extramural learning refers to the educational process that takes place outside the walls of the school (or the university). Extramural learning that takes place in a science center is characterized by hands-on and interactivity. Interactive solar energy exhibits are particularly well suited for out-door science centers. The paper presents some solar energy hands-on exhibits and extramural activities that the author has initiated and participated in.

    Abstract [en]

    Two different concentrating mirrors have been constructed that resemble parabolic dish reflectors. Both mirrors are made of slightly curved strips of flat, bendable material. The strips of the most simplified mirror have only large-radius circles and straight lines as boundaries. The necessary equations for making the mirrors are given. Also a simple way to make a stiff, lightweight frame and support for the mirror strips has been developed. Models of the mirrors have been built and successfully used for cooking and baking.

    Solar collector geometries at high latitudes1991In: ISES Solar World Congress, Denver, CO, USA, 1991Conference paper (Refereed)
    Abstract [en]

    Insolation onto and energy output from solar collectors have been estimated for some typical high latitude locations using the F-Chart computer program and weather data from the Swedish Meteorological and Hydrological Institute. Optimum tilt for south-facing collectors at Swedish latitudes is approximately latitude minus 20 degrees for maximum yearly performance, and about latitude minus 30 degrees for maximum summer performance. If tracking is considered, vertical axis tracking seems favorable with energy gain larger than normal 1-axis tracking with latitude tilted axis.

    Square cones for TPV: experiments and computer simulations1998In: Fourth NREL Conference on Thermophotovoltaic Generation of Electricity, Denver, CO, USA, 1998Conference paper (Other academic)
    Abstract [en]

    The efficiency of a TPV generator is very dependent on selective optical properties of the chain emitter-filter-TPV cell-reflective backing. If a selective reflective edge filter using multiple reflections in dielectric layers is employed, the slope of the edge depends on the incidence angle interval. A special geometry, consisting of a double square cone between the (square) emitter and the (square) cell array, which narrows this angle interval significantly, has been constructed and investigated experimentally as well as with ray tracing analysis.

    Enhancing the optical efficiency of a thermophotovoltaic generator using square cones in combination with interference filters1998In: Second World Conference on Photovoltaic Solar Energy Conversion, Wien, Österrike, 1998Conference paper (Refereed)
    Abstract [en]

    The optical efficiency is a week link in all TPV systems. Many different approaches have been studied earlier, but not much on the possibility to use interference filters. Such filters can be designed to get alsmost any desired optical performance, as long as it is allowed to use a large number of layers in the multilayer stack. In practical applications this is very often not acceptable. Nevertheless such filters can still be quite good, at least for a very narrow range of incident angles. Therefore a double-cone geometry is proposed to be used in combination with such filters. This geometry will limit the range of incident angles onto the filter, which will then act more efficiently. The influence of the geometry is evaluated by means of model experiments, and a computer program has been constructed to be able to simulate this type of geometry using ray-tracing technique.

    Abstract [en]

    An apparatus for measuring TPV cell efficiencies at different radiation intensities and for different graybody emitter temperatures has been constructed. The apparatus has been used for measuring V-I characteristics, efficiencies and fill factors for several InGaAs TPV cells. Measured results are used to determine how cells may function together with edge filters, and those results are compared with theory.

    Optical properties of the Czechoslovakian Fresnel lens measured using a laser beam1989In: ISES Solar World Congress, Kobe, Japan, 1989Conference paper (Refereed)
    Abstract [en]

    Linear glass Fresnel lenses have been experimentally investigated by means of a narrow He-Ne laser beam, both at normal incidence and at various combinations of meridional and sagittal angles of incidence. Both rays incident on the flat and on the grooved side were studied. Results were compared with previous ray tracing results by Franc et al. The experiments suggest, contrary to ray tracing, that the grooves should face the sun in other than sun-tracking applications.

    Co-generation of electricity and heat from combustion of wood powder utilizing thermophotovoltaic conversion1994In: First NREL Conference on Thermophotovoltaic Generation of Electricity, Copper Mountain, CO, USA, 1994Conference paper (Other academic)
    Abstract [en]

    The development of a thermophotovoltaic converter that uses combustion of wood powder as energy source has started with development of the combustion source. During the last few months, we have constructed and tested a feeding mechanism and a combustion chamber that seem very promising. We manage to keep a 10 kW flame steadily burning for several minutes at the time, generating a temperature exceeding 1400 K. The plans for continued development of this and other components of the converter are discussed in the paper.

    Development of a TPV converter for co-generation of electricity and heat from combustion of wood powder1994In: First World Conference on Photovoltaic Energy Conversion, Hawaii, USA, 1994Conference paper (Refereed)
    Abstract [en]

    Wood fuel has a high energy density, 18.3 MJ/kg dry matter, and it is combustible also in existing oil furnaces (in the range 1-15 MW) with little alteration. In principle, wood powder would be a possible fuel for small scale combustion, and we are in the process of developing such a furnace. During the last few months, we have constructed and tested a feeding mechanism and a combustion chamber that seem very promising. As of November 1994, we have reached 1481 K and been able to keep the temperature around 1400 K for any length of time at the time in one of our two prototype burners. A joint TPV R&D program, in which we cooperate with researchers at National Renewable Energy Laboratory, Golden, CO, USA, is in the planning, aiming at co-generation of electricity and heat from refined wood fuel.

    Use of nonimaging concentrators for moderate concentration of sunlight onto PV cells1989In: 9thy European Photovoltaics Solar Energy Conference, Freiburg, Tyskland, 1989Conference paper (Refereed)
    Abstract [en]

    The square cornet type nonimaging concentrator has been shown useful for moderate concentration of sunlight onto photovoltaic solar cells, since it creates no hot spots at the exit aperture. In this paper are presented the mathematical formulas on which the cornet designs are based, results from computer simulations on overall cornet performance compared with measurements as well as exit aperture intensity variations, measured optical concentration ratios under controlled circumstances, and cell temperature measurements under realistic circumstances. In an Appendix are given performance curves for a large number of cornets as determined from computer simulations, covering the useful range of concentration factors and acceptance angles.

    Effekter och förändringar av ledarutveckling2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    En kommun ställs ofta inför en mängd olika utmaningar, som ställer krav påorganisationen, ledarna och medarbetarna. Hur ska kommunen bäst ta sig an dessautmaningar som samhället och omvärlden ställer för att kunna vara i framkant i sinorganisation och ständigt utveckla den? Att utveckla sina ledare som har en central roll iorganisationen kan vara ett taktiskt val av strategi för att nå målen som sätts upp iorganisationen. Alla frågor som rör kompetens, erfarenhet, utbildning och personlighetär centrala begrepp för att utveckla ledare (Day, Fleenor, Atwater, Sturm & McKee,2014). Syftet med föreliggande undersökning är att studera om ledarutvecklingen harbidragit med några förändringar eller effekter i kommunen. Genom att ha läst in sig påolika teorier, bland annat om ledarskap, kompetensutveckling och effekter av utvecklinghar en djupare förståelse ägt rum. Metoden i undersökningen är kvalitativ, därsemistrukturerade djupintervjuer har genomförts med åtta chefer som har genomgåttledarutvecklingen. Resultatet visar att efter genomförd ledarutveckling reflekterarcheferna mer över sitt ledarskap, de identifierar styrkor och utvecklingsområden vilketbidrar till kompetensutveckling för individen och för organisationen. De synligaeffekterna av kompetensutvecklingen beskrev cheferna att de fått genom en helhetssynoch en större förståelse för andra. Det skapades även en trygghet i sin ledarroll där deinsåg vikten av samverkan. Undersökningen kan bidra med att ge en bild av hur effektiven ledarutveckling kan vara. Genom att exempelvis skapa en öppenhet i organisationenoch ha tid för reflektion. Avslutningsvis framläggs några förslag på vad kommunen kanarbeta vidare med som exempelvis att fokusera mer på samverkan och skapatvärsektionella grupper. Även kommer några förslag på vidare forskning inom området.

    Spider-Man, den moderna superhjälten: En komparativ analys av de två filmserier som gjorts om superhjälten Spider-Man under 2000-talet2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna uppsats har som syfte att analysera de två filmserierna om superhjälten Spider-Man

    som hittills gjorts i Hollywood och i superhjältegenren. De jämförs och olika element som

    berättelser, karaktärer, ton och stil ställs mot varandra, diskuteras och analyseras samt vad

    de har för slags betydelse i filmerna och hur det också påverkar karaktären och historien.

    Serietidningarna som filmerna är baserade på tas också med i analysen då de också

    påverkar historien, karaktärerna och filmernas ton och stil, bland annat tas element från

    serietidningen upp som filmskaparna tagit med i filmerna och hur det kommer sig

    diskuteras. Litteratur och fan-analyser lyfts fram för att stärka analysen samt kommentarer

    och intervjuer från filmskaparna som visar de val dem gjort för att gestalta karaktären

    Spider-Man och den värld som han befinner sig i.

    Mitt resultat är att båda filmskaparna försöker gestalta karaktären på ett rättvist sätt genom

    att gestalta karaktärens personlighet rätt men också den värld som kretsar omkring honom

    men det görs på två väldigt olika tillvägagångssätt. Både när det gäller det narrativa

    berättandet och tonen och stilen på filmerna. Men det finns också en del likheter i filmerna,

    bland annat att de båda tar med element från serietidningarna för att tillfredsställa fansen

    till Spider-Man. Samtidigt har de båda filmerna olika toner och stilar i sitt berättande som

    förändrats genom åren.

    Från vita duken till svarta tavlan.: Filmproduktion som uttrycksform i högstadiet.2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Utgångspunkten i den här uppsatsen har varit att lyfta fram ungdomars reflektioner kring hur

    de uttrycker sig via film, i en diskussion där ett vuxenperspektiv generellt är framträdande i

    många andra studier om ungdomars mediepraktiker. Uppsatsen undersöker hur dagens

    högstadieelever använder film som en kommunikationsform, samt deras idéer kring hur detta

    skulle kunna användas som ett hjälpmedel inom skolan. Studien som ligger till grund för de

    teman som diskuteras utgörs av sex reflexiva intervjuer med högstadieelever från en skola i

    södra Sverige. Materialet från dessa samtal har genomgått en kvalitativ analys där

    gemensamma ämnen redovisas och analyseras.

    Att ungdomar idag har ett väldigt avslappnat och naturligt förhållningssätt till att

    uttrycka sig via film leder till intressanta och nytänkande användningsområden att redogöra

    för. Utöver mediets roll i elevernas vardag presenteras deras förslag på flertalet kreativa

    funktioner för det inom högstadiet. Resultatet av att välja ungdomarnas perspektiv på hur de

    använder film blir en utgångspunkt där mediet beskrivs som en tillgång och ett hjälpmedel.

    Ett uppfriskande och positivt synsätt som har fått inspirera uppsatsen angreppssätt av ämnet.

    Doulors erfarenheter av sitt arbete med somaliska invandrarkvinnor: En intervjustudie2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Doulor/kulturtolkar är kvinnor som ska ge sina kvinnliga landsmän stöd och hjälp i

    kontakten med den svenska hälso- och sjukvården. I Örebro läns landsting

    startades ett projekt med doulor/kulturtolkar under 2013. Syftet med denna studie

    är att utforska dessa doulors erfarenheter av sitt arbete och vilken information de

    anser är relevant för invandrarkvinnor som ska besöka en barnmorska i

    primärvården. Metoden har varit kvalitativ med individuella intervjuer med fem

    doulor i Örebro. Resultatet visade att invandrarkvinnor önskar stöd och

    information dels i form av hjälp att förstå språket och information i samband med

    besök i vården t.ex. på vårdcentral, dels i form av en djupare förklaring av

    innebörden i informationen. Doulornas uppgift har varit att förklara på ett sätt så

    att invandrakvinnorna förstår. Invandrarkvinnorna har också sökt stöd hos

    doulorna när de har haft oro angående kvinnlig könsstympning, och för att få veta

    vad cellprovtagning är. Slutsatsen är att denna studie visar överensstämmelse i

    hög grad med tidigare forskning inom området.

    Diabetes during childhood and adolescence: studies of insulin treatment, patient-reported outcomes, and evaluation of an empowerment-based education2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    There is a lack of studies demonstrating positive effects on glycaemic control and HRQoL in children and adolescents starting CSII treatment. Guidelines recommend measuring perceived HRQoL routinely. It is important to have questionnaires, not overly comprehensive or timeconsuming, to measure HRQoL in children and adolescents as well as their parents. Structured and person-centred education has been emphasized as a key to successful selfmanagement. Guided Self-Determination-Young (GSD-Y) is a person-centred communication and reflection method. The overall aim of this thesis was to increase the knowledge regarding glycaemic control, type of treatment, HRQoL, and a theory-based education among youth with type 1 diabetes.

    Study I was a retrospective case-control study comparing children and adolescents starting CSII (n=216), with a control group treated with MDI (n=215). Children and adolescents who had started CSII showed improvement in glycaemic control, measured as HbA1c, during the first six months. For boys, this improvement could be identified throughout the first year.

    In Study II, 197 parents and their children with type 1 diabetes completed the proxy and child versions of the questionnaires Check your Health and DISABKIDS to test the psychometric properties of Check your Health by proxy. The test of the reliability and validity of this questionnaire showed acceptable psychometric properties.

    Study III, an RCT evaluating a GSD-Y education, included 71 adolescents starting CSII and their parents. The intervention group (n=37) attended seven group education sessions, lasting for about two hours each, using the GSD-Y method. The participants were followed for six months. The GSD-Y method showed a positive effect on glycaemic control, especially for participants with an HbA1c above 63 mmol/mol (n=48) at inclusion (p= 0.037); furthermore, readiness to change increased (p=0.037). A correlation was identified between HbA1c and goal achievement (rs=-0.475, p=0.001), and readiness to change (rs=-0.487, p=0.001).

    In Study IV, 13 adolescents were interviewed after the intervention with GSD-Y. From the qualitative analysis, two categories emerged: the importance of context, and growing in power through the group process. An overarching theme that emerged from the interviews was the importance of expert and referent power in growing awareness of the importance of self-management, as well as mitigating the loneliness of diabetes. Further, the findings showed that it is valuable for adolescents to meet other young people in the same situation, and to share their experiences from living with diabetes.

    In conclusion the four studies showed, treatment with CSII may initially result in improved HbA1c. Group education with the GSD-Y method, for adolescents and their parents, has the potential to further improve HbA1c, mitigate the loneliness of diabetes, and contribute to conscious reflection about self-management. The Check your Health questionnaire by proxy has shown acceptable psychometric characteristics, and may be useful in both studies and clinical settings.

    A person-centered education for adolescents with type 1 diabetes - a randomized controlled trial2019In: Pediatric Diabetes, ISSN 1399-543X, E-ISSN 1399-5448, Vol. 20, no 7, p. 986-996Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Young people with type 1 diabetes and their parents need to receive person-centred education to be able to manage their diabetes. Guided Self-Determination-Young (GSD-Y) is a person-centred communication and reflection education model that can be used in educational programmes for young people with type 1 diabetes.

    OBJECTIVE: To evaluate whether GSD-Y leads to improved glycaemic control, increased self-perceived health and health-related quality of life, fewer diabetes-related family conflicts, and improved self-efficacy in a group-based intervention for adolescents starting continuous subcutaneous insulin infusion (CSII) and their parents.

    METHODS: This randomized controlled trial included 71 adolescents starting CSII. Participants were followed for twelve months. The intervention group (n=37) attended seven group training sessions over a period of five months, using the GSD-Y model, the control group received standard care. Variables evaluated were HbA1c, self-perceived health, health-related quality of life, family conflicts, self-efficacy, and usage of continuous glucose monitoring.

    RESULTS: When adjusted for sex and family conflicts, there was a difference in glycaemic control between the groups at twelve months, favouring the intervention group (62 vs. 70 mmol/mol, p=0.009). When analyses were performed on boys and girls separately and adjusted for family conflicts, the only difference detected was for boys after twelve months (p=0.019). The intervention showed no effect on self-perceived health, health-related related quality of life, family conflicts, or self-efficacy.

    CONCLUSIONS: An intervention with GSD-Y may have an effect on glycaemic control. The content of the GSD-Y groups may serve as a model for person-centred care in adolescents with type 1 diabetes. This article is protected by copyright. All rights reserved.

    A multicentre randomized controlled trial of an empowerment-inspired intervention for adolescents starting continuous subcutaneous insulin infusion: a study protocol2013In: BMC Pediatrics, ISSN 1471-2431, E-ISSN 1471-2431, Vol. 13, article id 212Article in journal (Refereed)
    Abstract [en]

    Background. Continuous subcutaneous insulin infusion (CSII) treatment among children with type 1 diabetes is increasing in Sweden. However, studies evaluating glycaemic control in children using CSII show inconsistent results. Omitting bolus insulin doses using CSII may cause reduced glycaemic control among adolescents. The distribution of responsibility for diabetes self-management between children and parents is often unclear and needs clarification. There is much published support for continued parental involvement and shared diabetes management during adolescence. Guided Self-Determination (GSD) is an empowerment-based, person-centred, reflection and problem solving method intended to guide the patient to become self-sufficient and develop life skills for managing difficulties in diabetes self-management. This method has been adapted for adolescents and parents as Guided Self-Determination-Young (GSD-Y). This study aims to evaluate the effect of an intervention with GSD-Y in groups of adolescents starting on insulin pumps and their parents on diabetes-related family conflicts, perceived health and quality of life (QoL), and metabolic control. Here, we describe the protocol and plans for study enrolment.

    Methods. This study is designed as a randomized, controlled, prospective, multicentre study. Eighty patients between 12-18 years of age who are planning to start CSII will be included. All adolescents and their parents will receive standard insulin pump training. The education intervention will be conducted when CSII is to be started and at four appointments in the first 4 months after starting CSII. The primary outcome is haemoglobin A1c levels. Secondary outcomes are perceived health and QoL, frequency of blood glucose self-monitoring and bolus doses, and usage of carbohydrate counting. The following instruments will be used to evaluate perceived health and QoL: Disabkids, 'Check your health', the Diabetes Family Conflict Scale and the Swedish Diabetes Empowerment Scale. Outcomes will be evaluated within and between groups by comparing data at baseline, and at 6 and 12 months after starting treatment.

    Results and discussion. In this study, we will assess the effect of starting an insulin pump together with the model of Guided Self-Determination to determine whether this approach leads to retention of improved glycaemic control, QoL, responsibility distribution and reduced diabetes-related conflicts in the family.

    Adolescents’ perceptions of participation in group education using the Guided Self-Determination-Young method: a qualitative study2017In: BMJ Open Diabetes Research & Care, ISSN 2052-4897, Vol. 5, no 1, article id e000432Article in journal (Refereed)
    Abstract [en]

    Objective Guided Self-Determination (GSD) is a person-centered communication and reflection method. Education in groups may have a greater impact than the content of the education, and constructive communication between parents and adolescents has been shown to be of importance. The purpose of this study was to describe adolescents’ perceptions of participation in group education with the Guided Self-Determination-Young (GSD-Y) method, together with parents, in connection with the introduction of continuous subcutaneous insulin infusion.

    Research design and methods In the present qualitative interview study, 13 adolescents with type 1 diabetes were included after completing a GSD-Y group education program in connection with the introduction of continuous subcutaneous insulin infusion at three hospitals located in central Sweden. The adolescents were interviewed individually, and qualitative content analysis was applied to the interview transcripts.

    Results Two categories that emerged from the analysis were the importance of context and growing in power through the group process. An overarching theme that emerged from the interviews was the importance of expert and referent power in growing awareness of the importance of self-management as well as mitigating the loneliness of diabetes.

    Conclusions GSD-Y has, in various ways, mitigated experiences of loneliness and contributed to conscious reflection about self-management in the group (referent power) together with the group leader (expert power). Overall, this highlights the benefits of group education, and the GSD method emphasizes the person-centered approach.

    Parent's perception of their children's health, quality of life and burden of diabetes: testing reliability and validity of 'Check your Health' by proxy.2017In: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 31, no 3, p. 497-504Article in journal (Refereed)
    Abstract [en]

    AIM: To test the validity and reliability of the 'Check your Health by proxy' instrument in parents to children with diabetes aged 8-17 years.

    METHODS: One hundred and ninety-one caregivers and their children, aged 8-17 years, were included. All completed the 'Check your Health' questionnaire measuring quality of life and burden of diabetes, DISABKIDS self- or proxy version, and 45 completed the same questionnaires 2 weeks later.

    RESULTS: Test-retest reliability on the 'Check your Health' questionnaire by proxy was moderate to strong (r = 0.48-0.74), p < 0.002). Convergent validity was weak to moderate (r = 0.15-0.49, p < 0.05). The instrument showed acceptable discriminant validity. Parents reported lower scores than the children on emotional health and social relations and higher scores on physical and emotional burden and higher burden on quality of life. Poorer social relationships and quality of life were associated with higher reported disease severity. The diabetes burden domain of the questionnaire correlated to perceived severity of diabetes and to perceived health. Discriminant validity showed that poorer social relationships and quality of life were associated with higher severity of the disease. The diabetes burden domain of 'Check your Health' by proxy showed discriminant validity on perceived severity of diabetes.

    CONCLUSIONS: The instrument 'Check your Health' by proxy showed acceptable psychometric characteristics in parents to young people (8-17 years of age) with diabetes. We also concluded that parents reported that their children had lower health and higher burden of diabetes than the children did, and it correlated to reported disease severity.

    Does treatment with an insulin pump improve glycaemic control in children and adolescents with type 1 diabetes? A retrospective case-control study.2015In: Pediatric Diabetes, ISSN 1399-543X, E-ISSN 1399-5448, Vol. 16, no 7, p. 546-53Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To investigate long-term effects on glycaemic control, ketoacidosis, serious hypoglycaemic events, insulin requirements, and body mass index standard deviation scores (BMI-SDS) in children and adolescents with type 1 diabetes starting on continuous subcutaneous insulin infusion (CSII) compared with children and adolescents treated with multiple daily injections (MDI).

    METHODS: This retrospective case-control study compares 216 patients starting CSII with a control group on MDI (n = 215), matched for glycated hemoglobin (HbA1c), sex, and age during a 2-yr period. Variables collected were gender, age, HbA1c, insulin requirement, BMI, BMI-SDS, ketoacidosis, and serious hypoglycaemic events.

    RESULTS: In the CSII group there was an improvement in HbA1c after 6 and 12 months compared with the MDI group. For boys and girls separately the same effect was detected after 6 months, but only for boys after 12 months. The incidence of ketoacidosis was higher in the CSII group compared with the MDI group (2.8 vs. 0.5/100 person-yr). The incidences of severe hypoglycaemic episodes per 100 person-yr were three in the CSII group and six in the MDI group (p < 0.05). After 6, 12, and 24 months, the insulin requirement was higher in the MDI group.

    CONCLUSIONS: This study shows that treatment with CSII resulted in an improvement in HbA1c levels up to 1 yr and decreased the number of severe hypoglycaemic events, but the frequency of ketoacidosis increased. The major challenge is to identify methods to maintain the HbA1c improvement, especially among older children and teenagers, and reduce the frequency of ketoacidosis.

    Increasing Activation of the Gluteus Medius using a New Training Device2012In: Journal of Sport and Health Research, ISSN 1989-6239, Vol. 4, no 3, p. 311-320Article in journal (Refereed)
    Abstract [en]

    Objective: The gluteus medius (GM) is a strong abductor and medial rotator of the thigh, and plays an important role in stabilizing the pelvis and controlling the knees during athletic activities.Weakness in the GM can have adverse effects onperformance and increase the risk of lower extremityinjuries. The aim of this study was to validate a newtraining device by comparing the activation of theGM when performing a squat with and without thedevice. Methods: Thirty-two female athletes (mean age 20 ± 3) performed body weight squats on and offthe device, while surface electromyography wasrecorded bilaterally on the GM. Results: All testsubjects were able to perform the squat and toactivate the GM. The activation of the GM was significantly higher when using the new device than when performing squats on the floor (Z=-4.9,P<0.001). Correlation tests between a complete sequence of three squats and one selected repetition revealed that activation was consistent throughout theexercise (right GM: rs=0.93, P<0.001, left GM:rp=0.92, P<0.001). No differences in activation were found between the right and left GM when squatting on the device. Conclusion: The newly developed training device increases muscle activity in the GM during squats. Moreover, the results showed thatsquatting on the device activates the left and rightside of the body equally, and that the GM was activated during the whole hip flexion exercise. This information and the new training device can be usedin training programs to improve stabilization of the pelvis and lower extremities during dynamic exercises.

    A new electronic grip force measurement device for hand evaluation2013In: Abstracts of the Annual European Congress of Rheumatology EULAR. June 12-15, 2013. Madrid, Spain, 2013Conference paper (Refereed)
    Abstract [en]

    Background: Hand grip force is a good indicator of general muscle strength and can also be used to predict multiple outcomes such as changes in activities of daily living (ADL), disability, mortality and general upper extremity strength. Hand grip force is often measured as the amount of static grip force a subject can produce when measured with a hydraulic dynamometer such as the Jamar or with an electronic device such as the Grippit. The Grippit device measures an average grip force, a peak grip force and force over a set time period. Grippit has shown good reliability for healthy subjects. Grippit, which was developed over 20 years ago in Gothenburg, Sweden is no longer manufactured. Therefore, the need for anewly developed and modernized measurement instrument for use in evaluating hand rehabilitation has arisen.

    Objectives: The aim of this study was to evaluate the test-retest reliability of the newly developed instrument GRIP-it and to describe and validate the relationship between grip force measurements from GRIP-it and the original Grippit device.

    Methods: Healthy controls (n=43) were included in the study. Two devices were used to evaluate grip force (Newton, N), (i) GRIP-it a newly developed device and (ii) Grippit. Both instruments were used to measure mean and maximal force over 10 seconds.

    Results: GRIP-it displayed a mean measurement error of -1.7 ± 0.5% and the corresponding error for Grippit was -1.6 ± 1.9%. All subjects completed the grip force tests and the results for three attempts for each hand. The test-retest reliability was excellent for both pieces of equipment, with ICCs ranging from 0.963 to 0.947 (CI 95% between 0.103 and 0.041) for GRIP-it and from 0.979 to 0.968 (CI 95% between 0.087 and 0.042) for Grippit.

    Relationships between Grippit and GRIP-it

    There was a significant difference between the measured values derived from Grippit and GRIP-it for both the dominant hand (P < 0.001) and the non-dominant hand (P < 0.01). Grippit gives in general a higher grip force measurement than GRIP-it which is also indicated by the slope (β1) of the regression lines that deviates from 1. However, there were no substantial differences in the grip force when comparing the measurements for the dominant hand with the non-dominant hand for either Grippit (P = 0.071) or GRIP-it (P = 0.404). Based on these non-significant differences between hands and the fact that the model estimates for the intercept (β0) and the slope (β1) are contained within the confidence intervals of the model estimates for the opposite hand, a combined model was derived. The linear regression analysis, with grip force measurements for both hands included, gives: GRIP-it = 49.0 + 0.779 · Grippit. This explains 89.6% of the variance in grip force analyzed by GRIP-it (P < 0.001) see Figure 2. To enable an estimation of grip force measured by Grippit based on GRIP-it values a regression analysis with Grippit as dependent variable gives: Grippit = -18.1 + 1.15 · GRIP-it, which explains 89.6% of the variance in grip force analyzed by Grippit (P < 0.001).

    Conclusions: This study showed that GRIP-it has excellent test-retest reliability. Measurements of grip force with GRIP-it are strongly related to those from the original Grippit. The newly developed GRIP-it shows great potential for use in the assessment of hand function and the evaluation of hand rehabilitation.

    A six-week hand exercise programme improves strength and hand function in patients with rheumatoid arthritis2009In: Journal of rehabilitation medicine, ISSN 1651-2081, Vol. 41, no 5, p. 338-42Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To evaluate the effects of hand exercise in patients with rheumatoid arthritis, and to compare the results with healthy controls.

    METHODS: Forty women (20 patients with rheumatoid arthritis and 20 healthy controls) performed a hand exercise programme. The results were evaluated after 6 and 12 weeks with hand force measurements (with a finger extension force measurement device (EX-it) and finger flexion force measurement with Grippit). Hand function was evaluated with the Grip Ability Test (GAT) and with patient relevant questionnaires (Disability of the Arm, Shoulder, and Hand (DASH) and Short Form-36). Ultrasound measurements were performed on m. extensor digitorum communis for analysis of the muscle response to the exercise programme.

    RESULTS: The extension and flexion force improved in both groups after 6 weeks (p < 0.01). Hand function (GAT) also improved in both groups (p < 0.01). The rheumatoid arthritis group showed improvement in the results of the DASH questionnaire (p < 0.05). The cross-sectional area of the extensor digitorum communis increased significantly in both groups measured with ultrasound.

    CONCLUSION: A significant improvement in hand force and hand function in patients with rheumatoid arthritis was seen after 6 weeks of hand training; the improvement was even more pronounced after 12 weeks. Hand exercise is thus an effective intervention for rheumatoid arthritis patients, leading to better strength and function.

    The relationship between finger flexion and extension force in healthy women and women with rheumatoid arthritis2012In: Journal of Rehabilitation Medicine, ISSN 1650-1977, E-ISSN 1651-2081, ISSN 1650-1977, Vol. 44, no 7, p. 605-608Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE:

    Balance between flexor and extensor muscle activity is essential for optimal function. The purpose of this pilot study was to compare the relationship between maximum finger flexion force and maximum finger extension force in women with rheumatoid arthritis and healthy women.

    METHODS:

    Twenty healthy women (median age 61 years) and 20 women with rheumatoid arthritis (median age 59.5 years, median disease duration 16.5 years) were included in the study. Finger extension force was measured with an electronic device, EX-it, and finger flexion force using Grippit. The Grip Ability Test and the score from the patient-reported outcome Disability Arm Shoulder and Hand were used to evaluate activity limitations.

    RESULTS:

    Patients with rheumatoid arthritis showed significantly decreased hand function compared with healthy controls. A correlation was found between extension force and flexion force in the healthy group (r = 0.65, p = 0.002),but not in the rheumatoid arthritis group (r = 0.25, p = 0.289).

    CONCLUSION:

    Impaired hand function appears to influence the relationship between maximum finger flexion and extension force. This study showed a difference in the relationship between maximum finger flexion and extension force in healthy controls and those with rheumatoid arthritis.
