Recension (övrigt vetenskapligt/konstnärligt)abstract
- Så har den äntligen kommit, den första boken om planeten Mars skriven av en svensk marsforskare och sann rymdentusiast. Ella Carlsson är doktorand vid institutet för Rymdfysik där hon analyserar data från instrumentet Analyzer of Space Plasma and Energetic Atoms (ASPERA) som finns ombord på europeiska sonden Mars Express. Ellas forskning går ut på att fastställa hur solvinden inverkar på Mars atmosfär och hur mycket av atmosfären som har eroderats bort under planetens utveckling. Hennes forskning är mycket viktig då den lägger nya pusselbitar till frågan om var vattnet på Mars tagit vägen. Ella har vid sidan om sitt stora rymdintresse en gedigen bakgrund inom farkostteknik. Innan civilingenjörsstudierna inom rymdteknik, som kom att leda fram till den nuvarande forskarutbildningen, var hon verksam som officer inom svenska flygvapnet med bl.a. FN uppdrag i Bosnien. Ella har dessutom fått möjlighet att delta vid två spännande simuleringar av mars-vistelser på Mars Desert Research Station (MDRS) Utah-öknen i USA respektive på Flashline Mars Archtic Research Station (FMARS) på Devon Island i arktiska Kanada. Forskningen kring Mars är nu inne i ett spännande skede efter att en rad uppdrag till planeten rönt enorma framgångar. För närvarande rullar två robotbilar på ytan och fyra sonder cirkulerar i omlopp kring planeten där Mars Reconnaissance Orbiter satelliten är det senaste tillskottet. Dessa har påbörjat, och kommer att fortsätta generera en mängd nya data som idag sysselsätter många forskargrupper runt om i världen. Vår kunskap om Mars ökar snabbare idag än den någonsin gjort tidigare. Därför är en svensk bok tillägnad den senaste utforskningen av Mars ytterst önskvärd och välkommen.

Ingår i: Linköping Universtity Electronic Press. - 1650-3740. ; 27:15
-
Konferensbidrag (refereegranskat)abstract
- The optimal manoeuvering of a vehicle during a collision avoidance manoeuvre is investigated. A basic model where the vehicle is modelled by a mass-particle and the mathematical formulation of the optimal manoeuvre are presented. The resulting two-point boundary problem is solved by an adaptive finite element method and the theory behind this method is described.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Intervjustudiens syfte var att undersöka arbetsförhållanden för psykologer och beteendevetare inom företagshälsovården i Västra Götalandsregionen. Metoden var strukturerad intervju och grundade sig på ARIA arbetsinnehållsanalys. Sammanlagt deltog sju psykologer och tre beteendevetare. Resultaten visade bland annat att pressen på att uppfylla kvoten för debiterbar tid hade stor påverkan på arbetssituationen. Så länge debiterbarheten uppfylldes var man dock mycket fri i utförande och metod. Friheten hade ett pris av att arbetet blev avvägt av att man själv satte gränser och normer för sitt arbete. Många upplevde även ökad konkurrens på marknaden och det fanns viss oro för hur det kommer att inverka på arbetsförhållanden i framtiden

- OBJECTIVE: The aim of this study was to evaluate possible differences between local social insurance offices with regard to their selection of clients for vocational rehabilitation. A further aim was to determine whether social insurance officers from different local insurance offices have uniform attitudes regarding professional practice in their application of the insurance system. METHODS: A register-based investigation of 815 vocational rehabilitees served by 6 local social insurance offices in a Swedish county. The study was supplemented with a questionnaire to 30 officers about attitudes to social insurance. RESULTS: The office with the lowest rate of sick-listing periods exceeding one year, and a high frequency of employment training, showed the highest degree of work resumption and the lowest pension rate after vocational rehabilitation. There were wide differences in attitude among the local social insurance officers regarding professional practice in their application of the system. CONCLUSION: Intra-county differences occur in handling people on sick-leave who undergo vocational rehabilitation. The local social insurance offices with the highest and lowest outcome rates of work resumption and disability pension, respectively, select clients for vocational rehabilitation from different categories of cases. Social insurance officers from different local offices differ in their attitudes towards the social insurance system and its clients.

- OBJECTIVE: The aim of this study was to describe general characteristics of patients with stroke who have a tendency to fall and to determine whether certain test instruments can identify fallers. METHODS: Patients treated in a stroke unit during a 12-month period were included. At inclusion assessments were made with Berg Balance Scale Berg Balance Scale, Stops Walking When Talking, Timed Up & Go (TUG) and diffTUG. At follow-up 6 or 12 months later, patients who had fallen were identified. RESULTS: During the time from discharge to follow-up on 159 patients, 68 patients fell and 91 did not. Fallers fell more often during their initial hospital stay, used sedatives more often and were more visually impaired, compared with non-fallers. The Berg Balance Scale, Stops Walking When Talking and TUG results differed between fallers and non-fallers. The combined results of Berg Balance Scale and Stops Walking When Talking increased the possibility of identifying fallers. CONCLUSION: Berg Balance Scale, Stops Walking When Talking and TUG can be used to evaluate which patients have a tendency to fall in order to carry out preventive measures. Berg Balance Scale can be used in all patients. Stops Walking When Talking can give additional information if the patient is able to walk. TUG is a possible choice, but fewer patients can perform it.

- OBJECTIVE: The aim of this study was to assess if, and how, upper body muscles are activated in a person with high thoracic spinal cord injury, clinically classified as complete, during maximal voluntary contractions and in response to balance perturbations. METHODS: Data from one person with spinal cord injury (T3 level) and one able-bodied person were recorded with electromyography from 4 abdominal muscles using indwelling fine-wire electrodes and from erector spinae and 3 upper trunk muscles with surface electrodes. Balance perturbations were carried out as forward or backward support surface translations. RESULTS: The person with spinal cord injury was able to activate all trunk muscles, even those below the injury level, both in voluntary efforts and in reaction to balance perturbations. Trunk movements were qualitatively similar in both participants, but the pattern and timing of muscle responses differed: upper trunk muscle involvement and occurrence of co-activation of ventral and dorsal muscles were more frequent in the person with spinal cord injury. CONCLUSION: These findings prompt further investigation into trunk muscle function in paraplegics, and highlight the importance of including motor tests for trunk muscles in persons with thoracic spinal cord injury, in relation to injury classification, prognosis and rehabilitation.

- Objective and designThe prevalence of low back pain was assessed in relation to physical activity, for both work and leisure activities, in a randomly selected population in the northern part of Sweden. Additionally, the associations between age, sex, level of education, lifestyle factors, demographic characteristics, and low back pain were evaluated. Subjects: A total of 5798 subjects aged 25–79 years were selected randomly from a geographically well-defined area in northern Sweden. Methods: Additional questions concerning people's experience of low back pain were added to the questionnaire of the World Health Organization MONICA (MONItoring of trends and determinants in CArdiovascular disease) health survey with the aim of investigating prevalence rates and factors associated with low back pain. Results: Forty-one percent of the participants reported having low back pain (of these 55% were women and 45% men). The prevalence rate was highest in the age group 55–64 years. Chronic low back pain was the most frequent occurring problem. Of those with low back pain, 43% of the women and 37% of the men reported having continuous low back pain for more than 6 months. Individuals with low back pain often experienced a more physically heavy workload at work and lower physical activity during leisure time, and they were also more likely to have been smokers, have had higher body mass index, lived in smaller communities, and were less educated than people without low back pain. Conclusion: Low back pain seems to be associated with physical activity at work and in leisure time, certain lifestyle factors and demographic characteristics.

Can rehabilitation in the home setting reduce the burden of care for the next-of-kin of stroke victims?
- 2007
-
Ingår i: J Rehabil Med. - : Medical Journals Sweden AB. ; 39:1, s. 27-32
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: More evidence of the efficacy of caregiver interventions is needed. The aim of this study was to evaluate whether counselling in the home setting reduces the caregiver burden. METHODS: Thirty-six patients after stroke, median age 53 years, with a close family member, were selected for an evaluation of the burden of care and 35 participated. They were part of a randomized controlled trial, comparing rehabilitation in the home setting with outpatient rehabilitation. In the home setting, counselling about the stroke and its consequences was included. Assessments with the Caregiver Burden scale were made at 3 weeks, 3 months and one year after discharge. RESULTS: The burden of the 2 groups did not differ. After the intervention, there was a tendency to a lower burden for the home setting. The burden for the home setting was then unchanged from 3 weeks to 1 year, while outpatient rehabilitation showed a reduced burden over time. For the home setting, significant correlations to activity level were seen after the intervention. CONCLUSION: A positive effect of counselling was seen, as the home setting burden tends to be lower after the intervention, while outpatient rehabilitation seems to adjust with time. The results suggest that counselling reduces burden and the remaining burden is associated with the patient's ability.
