  • Cognitive function and walking velocity in people with dementia : a comparison of backward and forward walking
  • 2017
  • Ingår i: Gait & Posture. - : Elsevier. - 0966-6362 .- 1879-2219. ; 58, s. 481-486

    • How forward and backward walking, both central to everyday life, relate to cognition are relatively unexplored in people with dementia. This study aimed to investigate if forward and backward walking velocity respectively, associated with global cognition and executive function in people with dementia, and whether the association differed according to walking aid use or dementia type. Using a cross-sectional design, 161 participants (77% women), a mean Mini-Mental State Examination (MMSE) score of 15, and mean age of 85.5 years and living in nursing homes were included. Self-paced forward walking (FW) and backward walking (BW) velocity over 2.4 m was measured. Global cognitive outcome measurements included MMSE and Alzheimer Disease Assessment Scale - Cognitive subscale (ADAS-Cog). Executive function was measured using Verbal Fluency (VF). In comprehensively adjusted multivariate linear regression analyses, FW was independently associated with VF (p = 0.001), but not MMSE (p = 0.126) or ADAS-Cog (p = 0.818). BW was independently associated with VF (p = 0.043) and MMSE (p = 0.022), but not ADAS-Cog (p = 0.519). Interaction analyses showed that the association between BW velocity and executive function were stronger in participants who walked without a walking aid. No associations differed according to dementia type. In conclusion, executive function appears important to walking velocity, both forward and backward, in people with dementia with mild to moderately severe cognitive impairment. Global cognitive function was associated with backward walking only, perhaps due to it being more challenging. The association between BW velocity and executive function differed according to use of walking aids, which appeared to attenuate the association.

  • Experiences of older people with dementia participating in a high-intensity functional exercise program in nursing homes : "While it's tough, it's useful"
  • 2017
  • Ingår i: PLOS ONE. - : PUBLIC LIBRARY SCIENCE. - 1932-6203. ; 12:11
  • Tidskriftsartikel (refereegranskat)abstract
    • The objective of the study was to describe the views and experiences of participation in a high-intensity functional exercise (HIFE) program among older people with dementia in nursing homes. The study design was a qualitative interview study with 21 participants (15 women), aged 74-96, and with a Mini-Mental State Examination score of 10-23 at study start. The HIFE-program comprises exercises performed in functional weight-bearing positions and including movements used in everyday tasks. The exercise was individually designed, supervised in small groups in the nursing homes and performed during four months. Interviews were performed directly after exercise sessions and field notes about the sessions were recorded. Qualitative content analysis was used for analyses. The analysis revealed four themes: Exercise is challenging but achievable; Exercise gives pleasure and strength; Exercise evokes body memories; and Togetherness gives comfort, joy, and encouragement. The intense and tailored exercise, adapted to each participant, was perceived as challenging but achievable, and gave pleasure and improvements in mental and bodily strength. Memories of previous physical activities aroused and participants rediscovered bodily capabilities. Importance of individualized and supervised exercise in small groups was emphasized and created feelings of encouragement, safety, and coherence. The findings from the interviews reinforces the positive meaning of intense exercise to older people with moderate to severe dementia in nursing homes. The participants were able to safely adhere to and understand the necessity of the exercise. Providers of exercise should consider the aspects valued by participants, e.g. supervision, individualization, small groups, encouragement, and that exercise involved joy and rediscovery of body competencies.

  • Motivation to participate in high-intensity functional exercise compared with a social activity in older people with dementia in nursing homes
  • 2018
  • Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 13:11
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Motivation to participate in exercise among people with dementia has not been well studied. The symptoms of dementia, including apathy, may lead to low motivation to participate in exercise. The aim of this study was to evaluate the motivation of older people with dementia to participate in a high-intensity exercise program compared with motivation of those participating in a social group activity.Methods: The Umeå Dementia and Exercise Study (UMDEX) was a cluster-randomized controlled intervention trial including 186 people (mean age; 85, 75% female) with dementia in nursing homes. Participants were randomized to participate in the High-Intensity Functional Exercise (HIFE) Program (n = 93) or a seated social group activity (n = 93). The activities were conducted in groups of 3–8 participants for 45 minutes, five times per two-week period, for 4 months (40 sessions in total). Participants’ motivation to go to and during activity sessions were assessed by the activity leaders and nursing homes staff using a five-point Likert scale. Data were analyzed using cumulative link mixed models.Results: Motivation was high or very high during 61.0% of attended sessions in the exercise group and 62.6% in the social activity group. No overall significant difference between groups was observed, but motivation increased over time in the exercise group and decreased in the social activity group (p < 0.05). Motivation during the sessions was significantly higher than motivation to go to the sessions, especially in the exercise group [OR 2.39 (95% CI 2.38–2.40) and 1.50 (95% CI 1.32–1.70), respectively].Conclusions: Among older people with dementia in nursing homes, motivation to participate in a high-intensity functional exercise program seems to be high, comparable to motivation to participate in a social activity, and increase over time. Since motivation during activity sessions was higher than motivation to go to sessions the promotion of strategies to encourage people with dementia to join exercise groups is of great importance.

  • Stroke thrombolysis on equal terms? : implementation and ADL outcome
  • 2017
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Stroke thrombolysis is a method for restoring cerebral blood flow after ischemic stroke, with high priority in the Swedish national guidelines. implementation of stroke thrombolysis in Swedish routine stroke care has shown marked differences between demographic groups, hospital types, and regions. The general aim of this thesis were to examine the implementation of ischemic stroke thrombolysis in Swedish routine stroke care with an equity perspective; to gain more insight into the factors that influence implementation, how the treatment has reached patient groups, and differences in long-term outcomes between women and men. Analysis of data from research interviews with clinicians working within stroke care displayed that the facilitators of and barriers to the implementation of stroke thrombolysis could broadly be categorized into those related to individuals, to social interactions and context, and to organizational and resource issues. Key facilitating factors expressed in interviews were work pride and motivation, good leadership, involvement of all staff members in the implementation process, and quality assurance. Major barriers concerned lack of competence and experience, outdated attitudes regarding stroke management, counterproductive power structures, lack of continuity, and insufficient human resources. National quality register data displayed that stroke thrombolysis treatment expanded to reach more patients with mild deficits. Groups with higher education were more likely to receive treatment, compared to groups with lower educational level. These education group differences have, however, decreased over time in relative terms, but not in absolute terms. Further, there were considerable between-hospitals differences in treatment rates for patients with milder deficits, associated with hospital’s overall stroke thrombolysis rates. Moreover, larger non-university hospitals displayed treatment rate differences between educational groups that were not attributable to patient characteristics. Among thrombolysis-treated women and men, that was independent in ADL before their stroke and survived the first year post-stroke, women experienced higher probability to be dependent in ADL at both 3 and 12 months post-stroke, compared to men. This difference remained significant despite comprehensive adjustments for individual characteristics, symptom severity, and acute effects from stroke thrombolysis.This thesis displays that clinicians face barriers and facilitators at several levels, suggesting implementation interventions could be targeted towards both the individual-, the social interactions and context-, and also the organisation and available resources level. Assurance of clinicians’ individual competence, peer support, and clinical leadership seem to be important areas to intervene. Stroke thrombolysis rates have expanded over time, and an increase in stroke thrombolysis delivery to patients with mild stroke symptoms has contributed to this increase. However, it seems considerable differences between hospitals inhibit equity of care delivery. Further, socioeconomically disadvantaged groups receive less often stroke thrombolysis. Type of hospital seems to play a role, yet the reasons for this difference are not fully understood. This thesis also display that stroke thrombolysis-treated women that survive 1 year after stroke, appears to face higher risk for dependency in ADL, compared to men.

  • Effects of a High-Intensity Functional Exercise Program on Dependence in Activities of Daily Living and Balance in Older Adults with Dementia
  • 2016
  • Ingår i: Journal of The American Geriatrics Society. - : Wiley. - 0002-8614 .- 1532-5415. ; 64:1, s. 55-64
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To investigate the effects of a high-intensity functional exercise program on independence in activities of  daily living (ADLs) and balance in older people with dementia and whether exercise effects differed between dementia types.DESIGN: Cluster-randomized controlled trial: Umeå Dementia and Exercise (UMDEX) study.SETTING: Residential care facilities, Umeå, Sweden.PARTICIPANTS: Individuals aged 65 and older with a dementia diagnosis, a Mini-Mental State Examination score of 10 or greater, and dependence in ADLs (N = 186).INTERVENTION: Ninety-three participants each were allocated to the high-intensity functional exercise program, comprising lower limb strength and balance exercises, and 93 to a seated control activity.MEASUREMENTS: Blinded assessors measured ADL independence using the Functional Independence Measure (FIM) and Barthel Index (BI) and balance using the Berg Balance Scale (BBS) at baseline and 4 (directly after intervention completion) and 7 months.RESULTS: Linear mixed models showed no between-group effect on ADL independence at 4 (FIM=1.3, 95% confidence interval (CI)=-1.6-4.3; BI=0.6, 95% CI=-0.2-1.4) or 7 (FIM=0.8, 95% CI=-2.2-3.8; BI=0.6, 95% CI=-0.3-1.4) months. A significant between-group effect on balance favoring exercise was observed at 4 months (BBS=4.2, 95% CI=1.8-6.6). In interaction analyses, exercise effects differed significantly between dementia types. Positive between-group exercise effects were found in participants with non-Alzheimer's dementia according to the FIM at 7 months and BI and BBS at 4 and 7 months.CONCLUSION: In older people with mild to moderate dementia living in residential care facilities, a 4-month high-intensity functional exercise program appears to slow decline in ADL independence and improve balance, albeit only in participants with non-Alzheimer's dementia.

  • Effects of exercise on cognitive function in older people with dementia : a randomized controlled trial
  • 2017
  • Ingår i: Journal of alzheimers disease. - : IOS Press. - 1387-2877 .- 1875-8908. ; 60:1, s. 323-332
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Although physical exercise has been suggested to influence cognitive function, previous exercise studies show inconsistent results in people with dementia. Objectives: To investigate effects of exercise on cognitive function in people with dementia. Method: The Umea a Dementia and Exercise (UMDEX) study, a cluster-randomized controlled trial, was set in 16 nursing homes in Umea, Sweden. One hundred-and-forty-one women and 45 men with dementia; mean age of 85 y and mean MiniMental State Examination (MMSE) score of 15, were randomized to a High-Intensity Functional Exercise program or a seated attention control activity. Blinded assessors measured global cognitive function using the MMSE and the Alzheimer's disease Assessment Scale -Cognitive subscale (ADAS-Cog), and executive function using Verbal fluency (VF) at baseline and 4 months (directly after intervention completion), and MMSE and VF at 7 months. Results: Linear mixed models showed no between-group effects in mean difference from baseline (95% confidence intervals, CI) at 4 months in MMSE (-0.27; 95% CI -1.4 to 0.87, p = 0.644), ADAS-Cog (-1.04, 95% CI -4 to 1.92, p = 0.491), or VF (-0.53, 95% CI -1.42 to 0.35, p = 0.241) or at 7 months in MMSE (-1.15, 95% CI -2.32 to 0.03, p = 0.056) or VF (-0.18, 95% CI -1.09 to 0.74, p = 0.707). Conclusion: A 4-month, high-intensity functional exercise program had no superior effects on global cognition or executive function in people with dementia living in nursing homes when compared with an attention control activity.

  • The Effects of Exercise on Falls in Older People With Dementia Living in Nursing Homes : A Randomized Controlled Trial
  • 2019
  • Ingår i: Journal of the American Medical Directors Association. - : Elsevier. - 1525-8610 .- 1538-9375. ; 20:7, s. 835-842
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To investigate exercise effects on falls in people with dementia living in nursing homes, and whether effects were dependent on sex, dementia type, or improvement in balance. A further aim was to describe the occurrence of fall-related injuries.DESIGN: A cluster-randomized controlled trial.SETTING AND PARTICIPANTS: The Umeå Dementia and Exercise study was set in 16 nursing homes in Umeå, Sweden and included 141 women and 45 men, a mean age of 85 years, and with a mean Mini-Mental State Examination score of 15.INTERVENTION: Participants were randomized to the high-intensity functional exercise program or a seated attention control activity; each conducted 2-3 times per week for 4 months.MEASURES: Falls and fall-related injuries were followed for 12 months (after intervention completion) by blinded review of medical records. Injuries were classified according to severity.RESULTS: During follow-up, 118(67%) of the participants fell 473 times in total. At the interim 6-month follow-up, the incidence rate was 2.7 and 2.8 falls per person-year in exercise and control group, respectively, and at 12-month follow-up 3.0 and 3.2 falls per person-year, respectively. Negative binomial regression analyses indicated no difference in fall rate between groups at 6 or 12 months (incidence rate ratio 0.9, 95% confidence interval (CI) 0.5-1.7, P = .838 and incidence rate ratio 0.9, 95% CI 0.5-1.6, P = .782, respectively). No differences in exercise effects were found according to sex, dementia type, or improvement in balance. Participants in the exercise group were less likely to sustain moderate/serious fall-related injuries at 12-month follow-up (odds ratio 0.31, 95% CI 0.10-0.94, P = .039).CONCLUSIONS/IMPLICATIONS: In older people with dementia living in nursing homes, a high-intensity functional exercise program alone did not prevent falls when compared with an attention control group. In high-risk populations, in which multimorbidity and polypharmacy are common, a multifactorial fall-prevention approach may be required. Encouraging effects on fall-related injuries were observed, which merits future investigations.

  • Walking aids moderate exercise effects on gait speed in people with dementia : a randomized controlled trial
  • 2017
  • Ingår i: Journal of the American Medical Directors Association. - : Elsevier BV. - 1525-8610 .- 1538-9375. ; 18:3, s. 227-233
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To investigate the effects of exercise on gait speed, when tested using walking aids and without, and whether effects differed according to amount of support in the test.DESIGN: A cluster-randomized controlled trial.SETTING: The Umeå Dementia and Exercise (UMDEX) study was set in 16 nursing homes in Umeå, Sweden.PARTICIPANTS: One hundred forty-one women and 45 men (mean age 85 years) with dementia, of whom 145 (78%) habitually used walking aids.INTERVENTION: Participants were randomized to the high-intensity functional exercise program or a seated attention control activity.MEASUREMENTS: Blinded assessors measured 4-m usual gait speed with walking aids if any gait speed (GS), and without walking aids and with minimum amount of support, at baseline, 4 months (on intervention completion), and 7 months.RESULTS: Linear mixed models showed no between-group effect in either gait speed test at 4 or 7 months. In interaction analyses exercise effects differed significantly between participants who walked unsupported compared with when walking aids or minimum support was used. Positive between-group exercise effects on gait speed (m/s) were found in subgroups that walked unsupported at 4 and 7 months (GS: 0.07, P = .009 and 0.13, P < .001; and GS test without walking aids: 0.05, P = .011 and 0.07, P = .029, respectively).CONCLUSIONS: In people with dementia living in nursing homes exercise had positive effects on gait when tested unsupported compared with when walking aids or minimum support was used. The study suggests that the use of walking aids in gait speed tests may conceal exercise effects.
