- Background: The main aim was to examine whether patients with persistent upper quadrant pain have higher end-point variability in goal directed pointing movements than pain-free controls when the pointing task is performed in total darkness and under full vision. An additional aim was to study associations between the magnitude of end-point variability and a clinical movement control test battery and self-rated functioning among patients.Methods: Seventeen patients and 17 age- and gender-matched pain-free controls performed a pointing task that evaluated end-point variability of repetitive shoulder movements in horizontal adduction and abduction with full vision, and abduction with no visual information, completed a movement control test battery of neck and shoulder control tests and answered questionnaires.Results: Patients had higher end point variability for horizontal abduction when performed with no visual information. For horizontal adduction the variability was higher, but only when it was controlled for movement time. No significant correlations were found between end-point variability and self-rated functioning, nor between end-point variability and neuromuscular control of the glenohumeral joint.Conclusions: This study provides preliminary evidence that patients with persistent neck/shoulder pain can partly compensate proprioceptive deficits in goal-directed arm movement when visual feedback is present.

- This cross-sectional study on a random sample of 1,500 ambulance personnel investigated the relationships between self-reported work-related physical and psychosocial factors, worry about work conditions, and musculoskeletal disorders among female and male ambulance personnel. Three different outcomes, complaints, activity limitation, and sick leave, for the neck-shoulder and low-back region, respectively, were chosen. Among the female personnel, physical demands was significantly associated with activity limitation in the neck-shoulder (OR 4.13) and low-back region (OR 2.17), and psychological demands with neck-shoulder (OR 2.37) and low-back (OR 2.28) complaints. Among the male personnel, physical demands was significantly associated with low-back complaints (OR 1.41) and activity limitation (OR 1.62). Psychological demands and lack of social support were significantly associated with neck-shoulder complaints (OR 1.86 and OR 1.58, respectively) and activity limitation (OR 3.46 and OR 1.71) as well as activity limitation due to low-back complaints (OR 2.22 and OR 1.63). Worry about work conditions was independently associated with activity limitation due to low-back complaints among the female (OR 5.28), and to both neck-shoulder and low-back complaints (OR 1.79 and OR 2.04, respectively) and activity limitation (OR 2.32 and OR 1.95) among the male personnel. In conclusion, the association patterns between physical and psychological demands and MSDs suggest opportunities for intervention.

- Objectives: The aim of the present study was to assess physiological and subjective stress markers during a 24-h ambulance work shift and during the next two work-free days, and relate these parameters to self-reported health complaints. Methods: Twenty-six ambulance personnel were followed during a 24-h work shift and during the next two work-free days with electrocardiogram, cortisol assessments and diary notes. The ambulance personnel also performed tests of autonomic reactivity before and at the end of the work shift. The subjects were categorized into two groups according to their number of health complaints. Results: In general, stress markers did not show differences between the work shift and leisure time. However, a modest deviation in heart rate variability pattern and higher morning cortisol values during work in comparison with work-free days were observed in personnel with many health complaints. Conclusions: Subjective and physiological characteristics of ambulance personnel did not indicate distinctive stress during the 24-h work shift. Relationships between frequent health complaints and specific work-related factors require further prospective studies.

- The aim of the study was to evaluate the effects of individually prescribed physical exercise programmes on development of fatigue during the carrying of a loaded stretcher up and down the stairs. Nineteen ambulance personnel performed the training for 1 year. Testing occurred before and after 1 year of the training. Both the training group (n = 19) and the control group (n = 15) were assessed for physical capacity and lactate concentration in blood and ratings of perceived exertion during carrying a stretcher on the stairs. When comparisons were made between those who had been training three times/week for 1 year and the control group, lactate concentration was significantly decreased. In conclusion, markers of fatigue during stretcher carrying can be reduced by the use of individually prescribed physical exercise programmes.

- Prolonged computer use, especially if fatigue ensues, is associated with visual and musculoskeletal symptoms. The aim was to determine the time-course of perceived fatigue in the wrist, forearm, shoulder and eyes during a 60-min mouse task (painting rectangles), and whether object size and/or mouse use demands were of infl uence. Also, we investigated performance (number of rectangles painted), and whether perceived fatigue was paralleled by local muscle fatigue or tissue oxygenation.Ten women performed the task for three conditions (crossover design). At condition 1, rectangles were 45 25 mm, square paint cursor size 1.3 1.3 mm, and mouse – pointer movement ratio 1:26. At condition 2, the same cursor size and mouse – pointer movement ratio was used, but rectangles were smaller. At condition 3, the smaller rectangles were used, but the cursor size was also smaller and mouse – pointer movement ratio was 1:8. The results showed increased self-reported fatigue over time, with the observed increase greater for the eyes, but no change in physiological responses. Condition 2 resulted in higher performance and increased eye fatigue. Perceived fatigue in the muscles or physiological responses did not differ between conditions. In conclusion, computer work tasks imposing high visual and motor demands, and with high performance, seemed to have an infl uence on eye fatigue.

Challenges in Elderly Night-Time Care : Dignity 24 Hours a Day in Swedish Elderly Home Care Services?
- 2017

Ingår i: Innovation in Aging. - : Oxford University Press. - 2399-5300. ; 1:Suppl 1, s. 302-302

Tidskriftsartikel (refereegranskat)abstract
- The research study explores a large knowledge gap within Swedish elderly care – namely the challenges of within home care services at night. Despite that home care services is the most common support given to the elderly in Sweden. The few National and International studies that exist on night-time care, have focused on residential care facilities for the elderly. Therefore, focus here is on night-time care in their own homes, given by the night patrol – which we know very little about.In the last decades, organizational transformation has taken place within elderly care towards increased rationalization and marketization. Along with demographical changes, this raises questions of dignified care, equal social rights and access to care. As the elderly are living longer and living in their own homes with severe disability and vulnerability, the pressure on home care services will increase – including at night. Dignity in care has been legislated in the Swedish Social Services Act, but is vaguely implemented, specifically at night.Discussed are results of an interview survey with managers responsible for night-time home care services in 50 Swedish municipalities. How night-time care is organized varies depending on local governance, location and size of municipalities. This indicates challenges for equal access to care, depending on where you live. Care workers experience time pressure at night with many fragile elderly in need of care. How efforts to secure dignity and safety for older people varies over night is therefore important to reveal, not the least from a social equality perspective.

Swedish eldercare within home care services at night-time : perceptions and expressions of 'good care' from the perspective of care workers and care unit managers
- 2022

- This article aims to explore and analyse how good and dignified care is perceived and expressed at night-time within elder home care services, in which night-time care represents a knowledge gap. Dignity has become a legislated value in Swedish eldercare, aiming to increase the quality of care and to clarify the ethical values of everyday care practice. The data presented here come from a qualitative case study with in-depth interviews with six care unit managers and 14 care workers in four municipalities. The analysis of the interviewees’ perceptions and expressions of good care were informed by Nodding’s concepts: responsiveness, receptivity, and relatedness. The results showed that there was a relative unawareness of the new goals of the dignity policy and there was no specific guidance regarding dignity during night-time care. The care unit managers’ perspective was mainly administrative and related to the policy level and the staff’s ability to care. The care workers’ view of good and dignified care included aspects of ideal characteristics and user-centredness with a focus on older people’s individual needs. However, good care was conditioned by time. The dignity policy, as described in national documents, was perceived by the interviewees as vague and with unreachable goals constructed on the structural level. In social care practice, however, expressions of good and dignified care were already found in care ethics, regardless of the dignity policy. By bringing relationality to the dignity discourse on the structural policy level, recognition of care may be emphasized.

- Purpose: Multiple chemical sensitivity (MCS) is a prevalent medically unexplained symptom characterized by symptom reactions to everyday chemical exposure below hygienic thresholds. The aim of this study was to investigate the expressions of hyper-reactivity in MCS during whole-body exposure to low concentrations of the odorant n-butanol.Methods: We exposed 18 participants with MCS and 18 non-ill controls to a low concentration of the odorantn-butanol using an exposure chamber. The first 10 min constituted blank exposure, after which then-butanol concentration increased and reached a plateau at 11.5 mg/m3.Results: MCS participants, compared with controls, reported greater perceived odor intensities, more unpleasantness to the exposure and increasing symptoms over time. MCS participants also expressed higher pulse rate and lower pulse rate variability than controls did. No group differences were found for breathing rate or tonic electrodermal activity responses.Conclusions: We conclude that MCS sufferers differ from healthy controls in terms of autonomic responses, symptoms and chemosensory perception during chemical exposure.

Effects of Task Demands on Olfactory, Auditory, and Visual Event-Related Potentials Suggest Similar Top-Down Modulation Across Senses
- 2018

- A widely held view is that top-down modulation of sensory information relies on an amodal control network that acts through the thalamus to regulate incoming signals. Olfaction lacks a direct thalamic projection, which suggests that it may differ from other modalities in this regard. We investigated the late positive complex (LPC) amplitudes of event-related potentials (ERP) from 28 participants, elicited by intensity-matched olfactory, auditory and visual stimuli, during a condition of focused attention, a neutral condition, and a condition in which stimuli were to be actively ignored. Amplitudes were largest during the attend condition, lowest during the ignore condition, with the neutral condition in between. A Bayesian analysis resulted in strong evidence for similar effects of task across sensory modalities. We conclude that olfaction, despite its unique neural projections, does not differ from audition and vision in terms of task-dependent neural modulation of the LPC.
