- OBJECTIVE: To assess the reliability of 6 gait performance tests in individuals with chronic mild to moderate post-stroke hemiparesis.DESIGN: An intra-rater (between occasions) test-retest reliability study. Subjects: Fifty men and women (mean age 58+/-6.4 years) 6-46 months post-stroke.METHODS: The Timed "Up & Go" test, the Comfortable and the Fast Gait Speed tests, the Stair Climbing ascend and descend tests and the 6-Minute Walk test were assessed 7 days apart. Reliability was evaluated with the intraclass correlation coefficient (ICC(2,1)), the Bland & Altman analysis, the standard error of measurement (SEM and SEM%) and the smallest real difference (SRD and SRD%).RESULTS: Test-retest agreements were high (ICC(2,1) 0.94-0.99) with no discernible systematic differences between the tests. The standard error of measurement (SEM%), representing the smallest change that indicates a real (clinical) improvement for a group of individuals, was small (< 9%). The smallest real difference (SRD%), representing the smallest change that indicates a real (clinical) improvement for a single individual, was also small (13-23%).CONCLUSION: These commonly used gait performance tests are highly reliable and can be recommended to evaluate improvements in various aspects of gait performance in individuals with chronic mild to moderate hemiparesis after stroke.

- Objective: To assess the intra-rater (between occasions) test-retest reliability of isokinetic knee muscle strength measurements in subjects with chronic poststroke hemiparesis and to define limits for the smallest change that indicates real (clinical) improvements for stroke patients. Subjects: Fifty men and women (mean age 589±6.4 years) 6=±46 months post stroke, able to walk at least 300 m with or without a unilateral assistive device. Methods: Maximal concentric knee extension and flexion contractions at 608/s and 1208/s, and maximal eccentric knee extension contractions at 608/s, with the paretic and nonparetic limbs, were performed seven days apart using a Biodex dynamometer. Measures: Reliability of the maximum peak torque measurements was evaluated with the intraclass correlation coefficient (ICC2,1), the Bland and Altman analyses, the standard error of measurement (SEM and SEM%) and the smallest real difference (SRD and SRD%). Results: Test retest agreements were high (ICC2,1 0.89-0.96) with no discernible systematic differences between limbs, angular velocities and modes. The SEM%, representing the smallest change that indicates a real (clinical) improvement for a group of subjects, was relatively small (8-20%). The SRD%, representing the smallest change that indicates a real improvement for a single subject ranged from 26% to 33% for concentric knee extension, from 39% to 55% for concentric knee flexion, and from 22% to 25% for eccentric knee extension. Conclusion: Isokinetic knee muscle strength can be reliably measured and used to detect real improvements following an intervention for single subjects as well as for groups of subjects with chronic mild to moderate hemiparesis after stroke.

- There are several therapies designed to increase body awareness. They are commonly known as body awareness therapies ( BAT) and include Basic BAT, Mensendieck and Feldenkrais therapy. A focus on emotions is important in all these therapies. In this article the aim and development of Basic BAT is described together with evaluations of treatments including Basic BAT. Multidisciplinary studies have shown that Basic BAT can increase health-related quality of life and cost-effectiveness. However Basic BAT needs to be further studied in relation to patients with. fibromyalgia ( FM) and chronic pain. Studies so far indicate that Basic BAT has positive effects.

- Purpose. The purpose of this study was to describe the development of the Motivation for Change Questionnaire (MCQ) and to test its intra-patient reliability on musculoskeletal pain patients in interdisciplinary rehabilitation as a basis for use in rehabilitation planning. Method. The MCQ questionnaire was developed from a literature search in the Medline, Cinahl and Psychlit databases concerning motivating factors for change in the life and work situation. Questions covering these factors were developed (item generation). Factor analysis of the questions implied a reduction of the number of questions (item reduction). Inter-item correlation was assessed on the baseline administration of the questionnaire by calculating Cronbach's agr. When testing the structure of the scales, it was shown that the MCQ questionnaire could be described in two scales, one scale relating to motivation for change in the life situation and the other focusing on motivation for change in the work situation and in total 49 questions. Results. The test - retest reliability was calculated using the intra-class correlation coefficient (ICC) and 95% confidence intervals were calculated. One question was excluded due to the threshold limit of > 0.5. Seven scales relating to the life situation were accepted by the analysis: social support, mastery in life, challenges in life, control in life, values, self-efficacy and self-confidence. Six scales relating to the work situation were also accepted: co-worker support, supervisory support, challenges in work, job control, interaction and job-satisfaction. Conclusions. The MCQ questionnaire with 48 questions is reliable for use on musculoskeletal pain patients in interdisciplinary rehabilitation. It can be used to identify each individual's motivating factors for change in life and work situation as a basis for motivational work within rehabilitation and/or to measure within-subject changes in motivation over time. The validity and the responsiveness of the MCQ, need to be studied.

- There is a need for a deeper understanding of and discussion about different cultures' influences on life-views and ethical reasoning among professionals within healthcare. A culture can be seen as a set of guidelines, both explicit and implicit, which individuals inherit as members of a particular society, and which tells them how to view the world and how to behave in it in relation to other people. Do the cultural differences between Sweden, a culture predominantly influenced by Christian religion, and Turkey, a culture predominantly influenced by Muslim religion, influence physiotherapy students' life-views and ethical reasoning? The aim of this study was to compare life-views and questions of ethics between Swedish and Turkish physiotherapy students at the beginning of their studies. A reliable and valid questionnaire about life-views, together with questions covering ethical aspects was used. Three hundred and thirty-two physiotherapy students (186 Swedish, 146 Turkish) answered the same life-view questionnaire. Non-parametric statistics were used. Significant differences between the Swedish and Turkish students' opinions were analyzed with non-parametric statistics (Mann-Whitney U-test, two independent samples). Students' priorities in ethical questions were also compared between the groups. The Turkish students had significantly higher mean values in questions that belonged to a scientific life-view; the Swedish students had significantly higher mean values in questions belonging to an evolutionary life-view. There were significant differences between the groups in 14/20 individual life-view questions. The Swedish students were more patient-centered in their attitudes, had more positive attitudes to unconventional lifestyles and accepted to a higher extent than Turkish students suicide and euthanasia in special situations. Concerning priorities in ethical questions, there were significant differences between the groups concerning justice in healthcare and happiness for all, with higher priorities for happiness and justice in healthcare from the Turkish students.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: To describe how women with a spinal cord injury (SCI) perceived changes in the social network, and how these changes affected their ability to participate in occupation. METHOD: Thirteen women, aged 25 to 61 years, with a SCI were interviewed twice. The interviews focused on their ability to participate in occupation, their relations with individuals within the social network, and changes in the social network following the SCI. The analysis was carried out using qualitative content analysis. RESULTS: The women described an emotional need for social support after the SCI to participate in occupation. This was a new experience that required time to adapt to. The women also described a need for practical social support from the social network members to manage meaningful occupation. After the SCI, the women had developed new habits through close cooperation with members in the social network. The women felt that they had become more responsible for the development of their relations. Many relations had improved after the SCI, while some had decreased. The women had also developed new relations with other persons with disabilities. CONCLUSIONS: The women perceived substantial changes in the social network following the SCI, which in several ways affected their ability to participate in occupation. To adapt to their new life situation, the women gradually developed different strategies. The results point out the need to identify persons in the social network that women with SCI develop relations with, and integrate them in the rehabilitation process.

- A traumatic brain injury (TBI) extensively affects the injured person's daily life. Research based on the perspectives of people with TBI can increase understanding of the challenges they face and the possibility of supporting them in managing their lives. The aim of this study was to elucidate the meaning of living with TBI as narrated by the people with moderate or severe TBI. The data were collected by means of qualitative research interviews with 12 participants who had lived with TBI for 4-13 years. A phenomenological hermeneutic method was used to interpret the transcribed interviews. The study showed that people with TBI had lost their way and struggled to achieve a new normalcy. Losing one's way included experiences of waking up to unknown, missing relationships and experiencing the body as an enemy. Participants' struggles to attain a new normalcy included searching for an explanation, recovering the self, wishing to be met with respect, and finding a new way of living. Living with TBI seems to mean living with a perpetually altered body that changed the whole life and caused deep suffering, where feelings of shame and dignity competed with each other. Participants seem to be quite alone in their suffering and need more support from healthcare professionals.

The behaviour of satellite cells in response to exercise : what have we learned from human studies?

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Understanding the complex role played by satellite cells in the adaptive response to exercise in human skeletal muscle has just begun. The development of reliable markers for the identification of satellite cell status (quiescence/activation/proliferation) is an important step towards the understanding of satellite cell behaviour in exercised human muscles. It is hypothesised currently that exercise in humans can induce (1) the activation of satellite cells without proliferation, (2) proliferation and withdrawal from differentiation, (3) proliferation and differentiation to provide myonuclei and (4) proliferation and differentiation to generate new muscle fibres or to repair segmental fibre injuries. In humans, the satellite cell pool can increase as early as 4 days following a single bout of exercise and is maintained at higher level following several weeks of training. Cessation of training is associated with a gradual reduction of the previously enhanced satellite cell pool. In the elderly, training counteracts the normal decline in satellite cell number seen with ageing. When the transcriptional activity of existing myonuclei reaches its maximum, daughter cells generated by satellite cell proliferation are involved in protein synthesis by enhancing the number of nuclear domains. Clearly, delineating the events and the mechanisms behind the activation of satellite cells both under physiological and pathological conditions in human skeletal muscles remains an important challenge.

Tidskriftsartikel (refereegranskat)abstract
- The electronic properties and structure of a complex incorporating a self-interstitial (i) and two oxygen atoms are presented by a combination of deep level transient spectroscopy (DLTS), infrared absorption spectroscopy and ab-initio modeling studies. It is argued that the IO2 complex in Si can exist in four charge states (IO2-, IO20, IO2+, and IO2++). The first and the second donor levels of the IO2 complex show an inverted location order in the gap, leading to a E(0/+ +) occupancy level at E-V + 0.255 eV. Activation energies for hole emission, transformation barriers between different structures, and positions of LVM lines for different configurations and charge states have been determined. These observables were calculated by density-functional calculations, which show that they are accounted for if we consider at least two charge-dependent defect structures.
