- To improve the understanding of experiences of people with mild Alzheimer's disease (AD) and their significant others, related to the physical activity of the afflicted persons and its perceived importance. A qualitative case study design was used. The study comprised two men with mild AD and their wives. Data were collected by qualitative interviews and participant observations. Data analysis followed a thematic guideline as described by Braun and Clarke ( 2006 ). Three central themes of experiences related to physical activity in AD were identified: 1) physical activity as health reinforcement; 2) barriers to physical activity; and 3) adaptation strategies. Important motivations for outdoor walks were enjoyable experiences of nature, body movement, and positive attitudes toward physical activity. Several factors were experienced as barriers to physical activity (e.g., tiredness, difficulties in finding one's way, and "peculiar behavior"). Significant others made considerable adjustments in everyday life to enable their partners to retain a physically active lifestyle. The findings indicate that in persons with AD, physical activities such as outdoor walking can play an important part in everyday life by creating meaningful routines and improving experienced well-being and health.

- New methods to screen for and identify early-stage dementia disorders are highly sought after. The purpose of this pilot study is to develop a study protocol for a dual-task test aimed at aiding the early detection of dementia disorders. We used the Timed Up-and-Go (TUG) test, which is a mobility task involving starting in a sitting position, standing up, walking three meters to cross a line on the floor, turning around, walking back and sitting down again. We combined TUG with the verbal task of naming different animals. Pilot study participants were 43 individuals with and without established dementia diagnoses who attended a clinic for memory assessment. Video-recorded test performances were systematically analysed. Deviant test performances concerning the interplay between test administration and participants' responses to the assessment instructions were revealed and led to refinements being made to the final study protocol. Exploration of the dual-task test outcome measures in a sub-sample of 22 persons, ten with and twelve without dementia, indicated that step-length and number of named animals after the turning point of the dual-task test might constitute appropriate measures for examining this kind of sample. We concluded that the refined study protocol is feasible for testing individuals undergoing initial memory assessments and healthy controls. Follow-up studies with larger samples are being carried out and will bring new knowledge to this area of research. It may also provide an opportunity for further studies exploring possibilities for broad clinical implementation.

- Objectives: To explore events and describe phases for temporal coordination of the sit-to-walk (STW) task, within a semistandardized set up, in subjects with stroke and matched controls. In addition, to assess variability of STW phase duration and to compare the relative duration of STW phases between the 2 groups.Design: Cross-sectional.Setting: Research laboratory.Participants: A convenience sample of persons with hemiparesis (n=10; age 50–67y), more than 6 months after stroke and 10 controls matched for sex, age, height, and body mass index.Interventions: Not applicable.Main Outcome Measures: Relative duration of STW phases, SE of measurement in percentage of the mean, and intraclass correlation coefficients (ICCs).Results: Four STW phases were defined: rise preparation, transition, primary gait initiation, and secondary gait initiation. The subjects with stroke needed 54% more time to complete the STW task than the controls did. ICCs ranged from .38 to .66 and .22 to .57 in the stroke and control groups, respectively. SEs of measurement in percentage of the mean values were high, particularly in the transition phase: 54.1% (stroke) and 50.4% (controls). The generalized linear model demonstrated that the relative duration of the transition phase was significantly longer in the stroke group.Conclusions: The present results extend existing knowledge by presenting 4 new phases of temporal coordination of STW, within a semistandardized set-up, in persons with stroke and in controls. The high degree of variability regarding relative STW phase duration was probably a result of both the semistandardized set up and biological variability. The significant difference in the transition phase across the 2 groups requires further study.

- Objectives: To analyse, describe and compare the frequency and energy intake of eating events, including specific food items, among diseased older men living in ordinary housing. Design: Descriptive and explorative. Setting: Interviews were performed in the participants’ home. Participants: Thirty-five co-living and 26 single-living men, 64-88 years of age. Participants had one of three chronic diseases associated with difficulties in buying and preparing food and with difficulties related to the meal situation: Parkinson’s disease, rheumatoid arthritis or stroke. Measurements: A repeated 24-h recall was used to assess food intake and meal patterns. Results: Eating events were distributed over a 24-h period. Co-living men had a higher (p=0.001) number of eating events/day; both hot and cold eating events were consumed more frequently. There was no difference between groups concerning energy intake. Co-living men had more often hot eating events cooked from raw ingredients (p=0.001) and more various vegetables/roots (p=0.003) included in such eating events. Conclusion: Single-living men may constitute a vulnerable group from a nutritional perspective, while co-living men, besides the pleasure of eating together, seem to get support with food and eating events from their partners. Hence, the group of single-living men, particularly those with a disability, should receive particular attention with regard to possible food-related difficulties.

Tidskriftsartikel (refereegranskat)abstract
- The aim of the present study was to address the question of how older men with somatic diseases living in ordinary housing approach the question of food-related activities. Further, any food-related activity adaptations consequent to effects of diseases and of alterred life circumstances were explored. Interviews were conducted with a purposeful sample of 18 co-living and singel-living men, 64-84 years old. They were diagnosed with Parkinson's disease, rhematoid arthritis, or stroke. In the analysis a thematic framework was used. The findings revealed three food-related approaches, namely 'Cooking as a pleasure', describing joy in cooking; 'Cooking as a need', indicating no habit or skills in cooking; and ' Food is served', that is being served meals by a partner. It was found that gender-related roles in particular, but also changed life circumstances, activity limitations, personal interests, and a wish to maintain continuity and independence, affected the men's approaches to these activities. This knowledge may be useful in attempts to facilitate and support food-related activities among elderly men with diseases. Health-care efforts in promoting food-related activities should preferably be individualised in respect to older men's approach to these activities.

- The aim of this qualitative study was to explore and describe the perceptions of physical activity held by older urban Swedish and Irish adults. Qualitative interviews were carried out with 30 people age 65 years and older (mean age 74.5), of whom 15 were living in Dublin and 15 were living in Stockholm. The "thematic framework" approach was used to analyze the data. Three central themes were identified regarding people's perceptions of physical activity: physical activity as self-expression, physical activity as interaction, and physical activity as health promotion. Participants' perceptions of physical activity tended to relate to their perceived level of physical activity, regardless of their cultural background. Certain culture-specific motivators and barriers to exercise were also identified. Less active Irish men were more likely to underestimate the health-promoting benefits of exercise.

- For older people balance control in standing is critical for performance of activities of daily living without falling. The aims were to investigate reliability of quantification of the usage of the two balance mechanisms M1 ‘moving the centre of pressure’ and M2 ‘segment acceleration’ and also to compare calculation methods based on a combination of kinetic (K) and kinematic (Km) data, (K–Km), or Km data only concerning M2. For this purpose nine physically fit persons aged 70–78 years were tested in narrow and single-leg standing. Data were collected by a 7-camera motion capture system and two force plates. Repeated measure ANOVA and Tukey's post hoc tests were used to detect differences between the standing tasks. Reliability was estimated by ICCs, standard error of measurement including its 95% CI, and minimal detectable change, whereas Pearson's correlation coefficient was used to investigate agreement between the two calculation methods. The results indicated that for the tasks investigated, M1 and M2 can be measured with acceptable inter- and intrasession reliability, and that both Km and K–Km based calculations may be useful for M2, although Km data may give slightly lower values. The proportional M1:M2 usage was approximately 9:1, in both anterio-posterior (AP) and medio-lateral (ML) directions for narrow standing, and about 2:1 in the AP and of 1:2 in the ML direction in single-leg standing, respectively. In conclusion, the tested measurements and calculations appear to constitute a reliable way of quantifying one important aspect of balance capacity in fit older people.

- The debate concerning older people's life spaces should be based on subjective priorities of the elderly themselves. The purpose of this study was therefore to improve the understanding of preferences of elderly care recipients regarding activity-related life space (ARLS) and life satisfaction. A mainly qualitative design was used. Fifteen persons aged 80-94 years, undergoing geriatric rehabilitation, were interviewed during hospital stay and on two follow-up occasions after discharge. Transcribed interviews were analyzed in line with the thematic framework approach. The results point to three approaches related to preferences of ARLS: hierarchical limitations, changing continuity, and boundary breaking. Adaptive approaches were employed when physical incapacity was considered a hindrance to activity, adaptations which as a rule resulted in limitations of ARLS preferences. Activity related to the area 'close to one's own body' emerged as one of three identified key activities with importance for life satisfaction, the others being socializing and going out of doors. Continuity of activity in a familiar life space was expressed as a common ideal. If the aim of geriatric rehabilitation is to improve care recipients' life satisfaction, attention needs to be paid to the subjective dimensions of the ARLS in the goal setting.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: We study dual-task performance with marker-free video recordings of Timed Up-and-Go tests (TUG) and TUG combined with a cognitive/verbal task (TUG dual-task, TUGdt).RESEARCH QUESTION: Can gait parameters be accurately estimated from video-recorded TUG tests by a new semi-automatic method aided by a technique for human 2D pose estimation based on deep learning?METHODS: Thirty persons aged 60-85 years participated in the study, conducted in a laboratory environment. Data were collected by two synchronous video-cameras and a marker-based optoelectronic motion capture system as gold standard, to evaluate the gait parameters step length (SL), step width (SW), step duration (SD), single-stance duration (SSD) and double-stance duration (DSD). For reliability evaluations, data processing aided by a deep neural network model, involved three raters who conducted three repetitions of identifying anatomical keypoints in recordings of one randomly selected step from each of the participants. Validity was analysed using 95 % confidence intervals (CI) and p-values for method differences and Bland-Altman plots with limits of agreement. Inter- and intra-rater reliability were calculated as intraclass correlation coefficients (ICC) and standard errors of measurement. Smallest detectable change was calculated for inter-rater reliability.RESULTS: Mean ddifferences between video and the motion capture system data for SW, DSD, and SSD were significant (p < 0.001). However, mean differences for all parameters were small (-6.4%-13.0% of motion capture system) indicating good validity. Concerning reliability, almost all 95 % CI of the ICC estimates exceeded 0.90, indicating excellent reliability. Only inter-rater reliability for SW (95 % CI = 0.892;0.973) and one rater's intra-rater reliability for SSD (95 % CI = 0.793;0.951) were lower, but still showed good to excellent reliability.SIGNIFICANCE: The presented method for extraction of gait parameters from video appears suitable for valid and reliable quantification of gait. This opens up for analyses that may contribute to the knowledge of cognitive-motor interference in dual-task testing.
