    • Injuries related to falls are a major threat to the health of older persons. A fall may result not only in an injury but also in a decreased sense of autonomy in the daily life. To be able to prevent such falls, a need to further understand the complex mechanisms involved in balance and walking is needed. Here we present an immersive virtual reality system, in which a person can move around while being subjected to various events, which may influence balance and walking

    • Falls and fractures among elderly persons constitute a major health problem. Many falls occur while walking and falls that occur during turning often result in a fracture. Methods aimed at understanding the complex mechanisms involved in walking should therefore assess tested individuals during walks and turns. In order to identify persons at risk and take the correct preventive measures, it is important to find methods that quantify movements as the tested persons are processing multisensory input. In a clinical setting this is sometimes difficult to achieve in a controlled manner, since tests are difficult to set exactly the same from one time to another. Using a virtual environment (VE) and a tracker system, conditions such as light, sound, events, body movements, and room size can be controlled and measured. Tests in VE can therefore be identically reproduced over and over again to evaluate if a person can withstand changing outer demands at any given moment. In order to perform quantitative measures 8 persons (21-74 years) were tested in immersive virtual reality. The VE was a corridor in which expected and unexpected events could be produced. Events studied were doors swinging open in front of the subjects during a walk and a virtual tilting of the environment. Trackers were used for collecting and analyzing the movement data. Our results show that the system was well tolerated among the subjects and that there was a clear tendency that the system could generate fall tendency among the subjects. There was also a difference among the subjects regarding walking strategies when subjected to the various events.

  • Morale in the oldest old : the Umeå 85+ study
  • 2005
  • Ingår i: Age and Ageing. - : Oxford University Press (OUP). - 0002-0729 .- 1468-2834. ; 34:3, s. 249-255
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: to describe morale among the oldest old, and to investigate which social, functional and medical factors are associated with morale in this population. DESIGN: a cross-sectional study. SETTING: a population-based study in the municipality of Umeå, a city in Northern Sweden. SUBJECTS: half of the 85-year-old population, and the total population of 90-year-olds and > or = 95-year-olds (95-103) were asked to participate (n = 319) and 238 were interviewed. METHODS: structured interviews and assessments during home visits, interviews with relatives and caregivers and review of medical charts. The 17-item Philadelphia Geriatric Center Morale Scale (PGCMS) was used to measure morale. Participants were assessed with the Barthel Activities of Daily Living (ADL) Index, Geriatric Depression Scale (GDS-15), Mini-Mental State Examination (MMSE), Mini Nutritional Assessment (MNA), and a symptom questionnaire. Multiple regression analyses were conducted to find independent factors to explain the variation in the PGCMS score. RESULTS: eighty-four per cent (n = 199) of those interviewed answered the PGCMS. Three-quarters had middle range or high morale. GDS score, type of housing, previous stroke, loneliness and number of symptoms, adjusted for age group and sex, explained 49.3% of the variance of total PGCMS score. CONCLUSIONS: a large proportion of the oldest old had high morale. The most important factors for high morale were the absence of depressive symptoms, living in ordinary housing, having previously had a stroke and yet still living in ordinary housing, not feeling lonely and low number of symptoms. The PGCMS seems applicable in the evaluation of morale among the oldest old.
