Questions: What is the physical ability of very old people? Is physical ability affected by age or sex? Is it affected by type of housing, level of independence in activities of daily living, cognition, or nutrition? Design: A population-based cross-sectional observational study. Participants: Half the 85-year-old population, and the total population aged 90 and = 95 (range 95-103) in Umea, Sweden who were measured in the Umea 85+ Study (n = 238). Outcome measures: Usual and fastest gait speed (m/s) over 2.4 metres, three consecutive chair stands (s), the Berg Balance Scale, and ability to perform the measures (yes/no). Results: The median (10th to 90th percentile) usual gait speed was 0.49 m/s (0.23-0.75), time to perform the chair stands test was 12.6 seconds (8.5-20.2), and the Berg Balance Scale score was 45 (0-54). Men had greater physical ability than women. An age-related decline in physical ability was seen in women, but not in men. The Berg Balance Scale showed no floor or ceiling effects, but gait speed and chair stands resulted in a floor effect, especially for women. Conclusion: There were large variations in physical ability in these very old people. These data provide valuable reference values of physical ability in the oldest age groups for commonly-used clinical measures. [ABSTRACT FROM AUTHOR]

BACKGROUND AND AIMS: Identification of the risk of falls in a cohort of interest is a prerequisite for a targeted fall prevention study. Motor tasks are widely used as baseline assessment in such studies, but there are only a few well-evaluated tests of motor performance to predict falls prospectively. This study was conducted to find out if the potential of the maximum step length (MSL) test can predict future falls in non-disabled older persons. METHODS: A modified version of the MSL test was used for baseline assessment in 56 communitydwelling, non-disabled elderly persons (mean age 67.7 yrs, SD 6 yrs; 57% women). During a follow-up of 1 year, falls were recorded in a daily calendar. RESULTS: During the follow-up, 30 persons (54%) fell, with no gender difference in reporting of falls between men and women. The adjusted mean valid step length and adjusted maximum valid step length were predictive of future falls with a sensitivity/specificity of 77%/62% and 70%/69%, respectively. Combining MSL test results with fall history increased sensitivity to 93% and 90%, respectively, but decreased specificity to 54% and 58%, respectively. CONCLUSIONS: The MSL test is a feasible tool, with low requirements in space, predicting future falls in communitydwelling older persons. In combination with history of falls, the sensitivity of the test increased considerably. [ABSTRACT FROM AUTHOR]

BACKGROUND AND AIMS: Falls are particularly common among older people living in residential care facilities. The aim of this randomized controlled trial was to evaluate the effectiveness of a high-intensity functional exercise program in reducing falls in residential care facilities. METHODS: Participants comprised 191 older people, 139 women and 52 men, who were dependent in activities of daily living. Their mean+/-SD score on the Mini-Mental State Examination was 17.8+/-5.1 (range 10-30). Participants were randomized to a high-intensity functional exercise program or a control activity, consisting of 29 sessions over 3 months. The fall rate and proportion of participants sustaining a fall were the outcome measures, subsequently analysed using negative binominal analysis and logistic regression analysis, respectively. RESULTS: During the 6-month follow-up period, when all participants were compared, no statistically significant differences between groups were found for fall rate (exercise group 3.6 falls per person years [PY], control group 4.6 falls per PY), incidence rate ratio (95% CI) 0.82 (0.49-1.39), p=0.46, or the proportion of participants sustaining a fall (exercise 53%, control 51%), odds ratio (95% CI) 0.95 (0.52-1.74), p=0.86. A subgroup interaction analysis revealed that, among participants who improved their balance during the intervention period, the exercise group had a lower fall rate than the control group (exercise 2.7 falls per PY, control 5.9 falls per PY), incidence rate ratio (95% CI) 0.44 (0.21-0.91), p=0.03. CONCLUSIONS: In older people living in residential care facilities, a high-intensity functional exercise program may prevent falls among those who improve their balance. [ABSTRACT FROM AUTHOR]

OBJECTIVE : To develop a questionnaire for self-rated perceived participation in various life areas and to evaluate its reliability and validity. DESIGN : Validation and test-retest study including multiple questionnaire-development steps. SETTING : Neurological rehabilitation centre. PARTICIPANTS : One hundred and fifteen consecutive patients with progressive neurological diseases on the rehabilitation centre's waiting list were eligible to take part in the study; 85 completed. Twenty-two professionals within neurological rehabilitation also took part. MAIN MEASURES : Reproducibility, internal consistency, content validity and clinical utility of the Rating of Perceived Participation (ROPP) questionnaire. RESULTS : The ROPP questionnaire focuses on (1) patient's perceived participation (22 items selected from categories of the participation domains of the International Classification of Functioning, Disability, and Health), (2) patient's satisfaction with the participation level and the desired support for changing it, and (3) patient's selection of the three domains where improvement is most desired. The reproducibility of the perceived-participation items was moderate to good; (weighted kappa >/=0.70 for all but two items) and for satisfaction, desired support, and selected domains it was good or very good (kappa >0.70 for all but in total three items). Test-retest agreement (intraclass correlation (ICC)(1,1) = 0.97) and internal consistency (Cronbach's alpha = 0.90) for the total score were high. The content validity and clinical utility were good. CONCLUSIONS : The ROPP questionnaire has sufficient psychometric reliability and validity and promises to be a useful questionnaire in neurological rehabilitation. Further research is needed to establish criterion validity and sensitivity to change. [ABSTRACT FROM AUTHOR]

BACKGROUND AND AIMS: Few studies have reported fall-risk factors for persons with dementia, and no successful randomized fall prevention studies have been published. The aim of this study was to identify characteristics associated with falls in patients with dementia in a psychogeriatric ward. METHODS: This prospective study comprised 204 patients with any diagnosis of dementia. It was carried out in a psychogeriatric ward specializing in the assessment and treatment of behavioral and psychological symptoms in patients with dementia (BPSD). Baseline patient data were collected from medical records, and covered physical, behavioral and cognitive areas. Falls were recorded during time spent in the ward and median follow-up time was 52.5 days. RESULTS: Eighty-two patients fell a total of 251 times. Factors significantly and independently associated with an increased risk of falling were male sex (IRR 3.36, 95% CI 2.02-5.61), failed 'copy design' activity (decreased visual perception) (IRR 2.37, 95% CI 1.24-4.52), and any walking difficulty on level ground (IRR 1.84, 95% CI 1.10-3.08). Statins were associated with a decreased risk of falling (IRR 0.29, 95% CI 0.10-0.86). Twenty-seven percent of the variation in falls was explained. CONCLUSIONS: Male sex, decreased visual perception, and walking difficulties were all associated with an increased number of falls, and the model explained 1/4 of the variation in falls. Well-planned furnishing and use of color to achieve a plain, clearly defined environment, as well as training in walking ability, may decrease the risk of falling in people with dementia.

BACKGROUND AND PURPOSE: It is unknown how cognitive impairment affects the reliability of Timed 'Up & Go' Test (TUG) scores. The aim of the present study was to investigate the expected variability of TUG scores in older subjects dependent in activities of daily living (ADL) and with different levels of cognitive state. The hypothesis was that cognitive impairment would increase the variability of TUG scores. SUBJECTS: Seventy-eight subjects with multiple impairments, dependent in ADL, and living in residential care facilities were included in this study. The subjects were 84.8+/-5.7 (mean+/-SD) years of age, and their Mini-Mental State Examination score was 18.7+/-5.6. METHODS: The TUG assessments were performed on 3 different days. Intrarater and interrater analyses were carried out. RESULTS: Cognitive impairment was not related to the size of the variability of TUG scores. There was a significant relationship between the variability and the time taken to perform the TUG. The intraclass correlations were greater than .90 and were similar within and between raters. In repeated measurements at the individual level, an observed value of 10 seconds was expected to vary from 7 to 15 seconds and an observed value of 40 seconds was expected to vary from 26 to 61 seconds for 95% of the observations. DISCUSSION AND CONCLUSION: The measurement error of a TUG assessment is substantial for a frail older person dependent in ADL, regardless of the level of cognitive function, when verbal cuing is permitted during testing. The variability increases with the time to perform the TUG. Despite high intraclass correlation coefficients, the ranges of expected variability can be wide and are similar within and between raters. Physical therapists should be aware of this variability before they interpret the TUG score for a particular individual. [ABSTRACT FROM AUTHOR]

BACKGROUND AND PURPOSE: Knowledge concerning the applicability and the effect of high-intensity exercise programs is very limited for older people with severe cognitive and physical impairments. The primary aim of this study was to evaluate the applicability of a high-intensity functional weight-bearing exercise program among older people who are dependent in activities of daily living and living in residential care facilities. A second aim was to analyze whether cognitive function was associated with the applicability of the program. SUBJECTS: The subjects were 91 older people (mean age=85.3 years, SD=6.1, range=68-100) who were dependent in personal activities of daily living and randomly assigned to participate in an exercise intervention. Their mean score for the Mini-Mental State Examination (MMSE) was 17.5 (SD=5.0, range=10-29). METHODS: A high-intensity functional weight-bearing exercise program was performed in groups of 3 to 7 participants who were supervised by physical therapists. There were 29 exercise sessions over 13 weeks. Attendance, intensity of lower-limb strength and balance exercises, and occurrence and seriousness of adverse events were the outcome variables in evaluating the applicability of the program. RESULTS: The median attendance rate was 76%. Lower-limb strength exercises with high intensity were performed in a median of 53% of the attended exercise sessions, and balance exercises with high intensity were performed in a median of 73% of the attended exercise sessions. The median rate of sessions with adverse events was 5%. All except 2 adverse events were assessed as minor and temporary, and none led to manifest injury or disease. No significant differences were observed in applicability when comparing participants with dementia and participants without dementia. In addition, there was no significant correlation between applicability and the MMSE score. DISCUSSION AND CONCLUSION: The results suggest that a high-intensity functional weight-bearing exercise program is applicable for use, regardless of cognitive function, among older people who are dependent in activities of daily living, living in residential care facilities, and have an MMSE score of 10 or higher.

OBJECTIVES: To evaluate the effectiveness of a multifactorial fall and injury prevention program in older people with higher and lower levels of cognition. DESIGN: A preplanned subgroup comparison of the effectiveness of a cluster-randomized, nonblinded, usual-care, controlled trial. SETTING: Nine residential facilities in Umeå, Sweden. PARTICIPANTS: All consenting residents living in the facilities, aged 65 and older, who could be assessed using the Mini-Mental State Examination (MMSE; n = 378). An MMSE score of 19 was used to divide the sample into one group with lower and one with higher level of cognition. The lower MMSE group was older (mean +/- standard deviation = 83.9 +/- 5.8 vs 82.2 +/- 7.5) and more functionally impaired (Barthel Index, median (interquartile range) 11 (6-15) vs 17 (13-18)) and had a higher risk of falling (64% vs 36%) than the higher MMSE group. INTERVENTION: A multifactorial fall prevention program comprising staff education, environmental adjustment, exercise, drug review, aids, hip protectors, and postfall problem-solving conferences. MEASUREMENTS: The number of falls, time to first fall, and number of injuries were evaluated and compared by study group (intervention vs control) and by MMSE group. RESULTS: A significant intervention effect on falls appeared in the higher MMSE group but not in the lower MMSE group (adjusted incidence rates ratio of falls P =.016 and P =.121 and adjusted hazard ratio P <.001 and P =.420, respectively). In the lower MMSE group, 10 femoral fractures were found, all of which occurred in the control group (P =.006). CONCLUSION: The higher MMSE group experienced fewer falls after this multifactorial intervention program, whereas the lower MMSE group did not respond as well to the intervention, but femoral fractures were reduced in the lower MMSE group.

Background: Falls and resulting injuries are particularly common in older people living in residential care facilities, but knowledge about the prevention of falls is limited.Objective: To investigate whether a multifactorial intervention program would reduce falls and fall-related injuries.Design: A cluster randomized, controlled, nonblinded trial.Setting: 9 residential care facilities located in a northern Swedish city.Patients: 439 residents 65 years of age or older.Intervention: An 11-week multidisciplinary program that included both general and resident-specific, tailored strategies. The strategies comprised educating staff, modifying the environment, implementing exercise programs, supplying and repairing aids, reviewing drug regimens, providing free hip protectors, having post-fall problem-solving conferences, and guiding staff.Measurements: The primary outcomes were the number of residents sustaining a fall, the number of falls, and the time to occurrence of the first fall. A secondary outcome was the number of injuries resulting from falls.Results: During the 34-week follow-up period, 82 residents (44%) in the intervention program sustained a fall compared with 109 residents (56%) in the control group (risk ratio, 0.78 [95% CI, 0.64 to 0.96]). The adjusted odds ratio was 0.49 (CI, 0.37 to 0.65), and the adjusted incidence rate ratio of falls was 0.60 (CI, 0.50 to 0.73). Each of 3 residents in the intervention group and 12 in the control group had 1 femoral fracture (adjusted odds ratio, 0.23 [CI, 0.06 to 0.94]). Clustering was considered in all regression models.Conclusion: An interdisciplinary and multifactorial prevention program targeting residents, staff, and the environment may reduce falls and femoral fractures.

Background: Accidental falls are one of the greatest threats to older adults' health and well-being. The risk of falling can be significantly reduced with strength and balance interventions. However, there needs to be further knowledge into how older adults can be supported to achieve a maintained exercise behaviour. Therefore, the aim of this study was to explore factors that enabled older adults to maintain their exercise during a 1-year self-managed digital fall prevention exercise intervention., Methods: This study used a grounded theory methodology. Semi-structured individual interviews were conducted by phone or conference call. Eighteen community-dwelling older adults aged 70 years or more participated. The participants had a self-reported exercise dose of 60 min or more per week during the last three months of participation in a 12-months intervention of self-managed digital fall prevention exercise, the Safe Step randomized controlled trial. Open, axial, and selective coding, along with constant comparative analysis, was used to analyze the data., Results: The analysis resulted in a theoretical model. We found that the fall prevention exercise habits of adults were developed through three stages: Acting against threats to one's own identity, Coordinating strategies to establish a routine, and Forming habits through cues and evaluation. The main category of Maintaining balance in life encases the participants transition through the three stages and reflects balance in both physical aspects and in between activities in daily life. The process of maintaining balance in life and desire to do so were mediated both by intrinsic person-dependent factors and the Safe Step application acting as an external mediator., Conclusion: This study identified three stages of how older adults developed self-managed fall prevention exercise habits, supported by a digital application. The generated theoretical model can inform future interventions aiming to support long-term engagement in digitally supported and self-managed fall prevention interventions., (© 2023.

Background: To have an impact on the population's health, preventive interventions have to reach a large proportion of the intended population. Digital solutions show potential for providing wider access to fall preventive exercise. However, there is a lack of knowledge about how to reach the target group. The aim of this study was to describe the recruitment process used in the Safe Step randomised controlled trial and the characteristics of the participants reached., Methods: Several recruitment methods, both digital and non-digital, were adopted to reach the intended sample size. Sociodemographic parameters from the baseline questionnaire were used to describe participant characteristics. The characteristics were also compared to a representative sample of older adults in the Swedish population., Results: In total, 1628 older adults were recruited. Social media proved to be the most successful recruitment strategy, through which 76% of the participants were recruited. The participants reached had a mean age of 75.9 years, lived in both urban and rural locations, were already frequent users of the Internet and applications (smartphone/tablet) (79.9%), had higher education (71.9%), and a large proportion were women (79.4%). In comparison with the general population participants in the Safe Step study were more highly educated ( p  < 0.001), women in the study more frequently lived alone ( p  < 0.001) and men more often reported poorer self-rated health ( p  = 0.04). Within the study, men reported a faster deteriorating balance ( p  = 0.003) and more prescribed medication ( p  < 0.001) than women., Conclusion: Recruitment via social media is a useful strategy for reaching older adults, especially women and frequent users of the Internet, for a fully self-managed and digital fall prevention exercise intervention. This study underlines that a range of interventions must be available to attract and suit older adults with different functional statuses and digital skills., Competing Interests: Declaration of Conflicting Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

Background: Adults with dementia have a high risk of falls and fall-related injuries. A greater slowing of backward walking speed (BWS) relative to forward (FWS) has been indicated with older age, and slower BWS has been related to an increased risk of falls. Similarly, slow BWS relative to FWS has been observed in people with dementia., Research Question: Is slower BWS, and slower BWS relative to FWS associated with increased risk of prospective falls in older adults with dementia?, Methods: In total, 52 women and 12 men with dementia living in nursing homes, mean age 86 years, and mean Mini-Mental State Examination score of 14.2 points were included. BWS and FWS was measured over 2.4 m, and the directional difference (DD) calculated (100*((FWS-BWS)/FWS)). Falls were followed for 6 months by review of fall incident reports in electronic medical records at nursing homes and the regional healthcare provider., Results: Altogether, 95 falls occurred with mean incidence rate 3.1 falls per person-years. Of included participants, 15 (23%) fell once, and 17 (27%) fell twice or more. In negative binomial regression analyses, greater DD was associated with lower prospective incidence fall rate ratio, IRR (IRR= 0.96, p < .001), while BWS was not (IRR= 0.04, p = .126)., Significance: In this study of adults with dementia, slower BWS was not associated with prospective falls. However, slower BWS relative to forward (greater DD) was associated with fewer falls, and possibly a protective response. This is novel research, yet results are promising and indicate that assessing walking speed in multiple directions may inform fall risk in adults with dementia., (Copyright © 2022 The Authors.

Background: There is robust evidence that falls in old age can be prevented by exercise programs that include balance training, functional exercises, and strength training. For the interventions to have a population health impact, outreach to the population of focus with suitable interventions is needed. While digital interventions are promising there is limited knowledge on the characteristics of who is reached. The aim of this study was to describe the recruitment process, estimate reach rate at the population level and to describe participants characteristics and representativeness in a digital fall prevention intervention study., Methods: In a municipality-based observational study, reach of a digital fall prevention intervention was evaluated. The intervention included a digital exercise programme (Safe Step) and optional supportive strategies, complemented with a range of recruitment strategies to optimize reach. Recruitment during a period of 6 months was open to people 70 years or older who had experienced a fall or a decline in balance the past year. Reach was based on data from the baseline questionnaire including health and demographic characteristics of participants. Representativeness was estimated by comparing participants to a sample of older people from the Swedish National Public Health Survey., Results: The recruitment rate was 4.7% ( n = 173) in relation to the estimated population of focus ( n = 3,706). Most participants signed up within the first month of the intervention ( n = 131). The intervention attracted primarily women, older people with high education, individuals who used the internet or digital applications almost every day and those perceiving their balance as fair or poor. Safe step participants lived more commonly alone and had higher education and better walking ability in comparison to the Swedish National Public Health Survey., Conclusions: With a range of recruitment strategies most participants were recruited to a digital fall intervention during the first month. The intervention attracted primarily highly educated women who frequently used the internet or smart technologies. In addition to digital fall prevention interventions, a higher diversity of intervention types (digital and non-digital) is more likely to reach a larger group of older people with different needs., Clinical Trial Registration: ClinicalTrials.gov, NCT04161625 (Retrospectively registered), https://clinicaltrials.gov/ct2/show/NCT04161625., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Bajraktari, Zingmark, Pettersson, Rosendahl, Lundin-Olsson and Sandlund.)

Background: Little is known about associations between performance-based measurements and self-reported scales, nor about ceiling effects or sensitivity to change to evaluate effects in the target population for self-managed exercise interventions. This study aimed to explore the feasibility of using performance-based outcomes for gait speed, functional leg strength and balance, and self-reported outcomes of falls-efficacy and functional ability in two self-managed falls prevention exercise interventions for community dwelling older adults., Methods: Independent living, community-dwelling older adults (n = 67) exercised with one of two self-managed falls prevention exercise programmes, a digital programme (DP) or a paper booklet (PB) in a 4-month participant preference trial. Pre- and post-assessments, by blinded assessors, included Short Physical Performance Battery (SPPB) and 30s Chair stand test (30s CST). Participants completed self-reported questionnaires: Activities-specific and Balance Confidence scale (ABC), Iconographical Falls Efficacy Scale (Icon-FES), Late-Life Function and Disability Instrument Function Component (LLFDI-FC). In addition, improvement in balance and leg strength was also self-rated at post-assessment. Participants' mean age was 76 ± 4 years and 72% were women., Results: Ceiling effects were evident for the balance sub-component of the SPPB, and also indicated for ABC and Icon-FES in this high functioning population. In SPPB, gait speed, 30s CST, and LLFDI-FC, 21-56% of participants did not change their scores beyond the Minimal Clinically Important Difference (MCID). At pre-assessment all performance-based tests correlated significantly with the self-reported scales, however, no such significant correlations were seen with change-scores. Improvement of performance-based functional leg strength with substantial effect sizes and significant correlations with self-reported exercise time was shown. There were no differences in outcomes between the exercise programmes except that DP users reported improved change of leg strength to a higher degree than PB users., Conclusion: The LLFDI-FC and sit-to-stand tests were feasible and sensitive to change in this specific population. The balance sub-component of SPPB and self-reported measures ABC and Icon-FES indicated ceiling effects and might not be suitable as outcome measures for use in a high functioning older population. Development and evaluation of new outcome measures are needed for self-managed fall-preventive interventions with high functioning community-dwelling older adults., (© 2022. The Author(s).)

Background: Exercise is an effective intervention to prevent falls in older adults; however, long-term adherence is often poor. To increase adherence, additional support for behavior change has been advocated. However, consistency in the reporting of interventions using behavior change techniques is lacking. Recently, a classification system has been developed to increase consistency in studies using behavior change techniques within the self-determination theory., Objective: This study aimed to explore expressions of self-determination among community-dwelling older adults using a self-managed digital fall prevention exercise program comprising behavior change support (the Safe Step program), which was developed in co-creation with intended users., Methods: The qualitative study design was based on open-ended responses to questionnaires, and individual and focus group interviews. A deductive qualitative content analysis was applied using the classification system of motivation and behavior change techniques as an analytical matrix, followed by an inductive analysis. Twenty-five participants took part in a feasibility study and exercised in their homes with the Safe Step program for 4 months. The exercise program was available on computers, smartphones, and tablets, and was fully self-managed., Results: In the deductive analysis, expressions of support were demonstrated for all three basic human psychological needs, namely, autonomy, competence, and relatedness. These expressions were related to 11 of the 21 motivation and behavior change techniques in the classification system. The inductive analysis indicated that autonomy (to be in control) was valued and enabled individual adaptations according to different rationales for realizing exercise goals. However, the experience of autonomy was also two-sided and depended on the participants' competence in exercise and the use of technology. The clarity of the program and exercise videos was seen as key for support in performance and competent choices. Although augmented techniques for social support were requested, support through relatedness was found within the program., Conclusions: In this study, the Safe Step program supported the establishment of new exercise routines, as well as the three basic human psychological needs, with autonomy and competence being expressed as central in this context. Based on the participants' experiences, a proposed addition to the classification system used as an analytical matrix has been presented., Trial Registration: ClinicalTrials.gov NCT02916849; https://clinicaltrials.gov/ct2/show/NCT02916849., (©Beatrice Pettersson, Rebecka Janols, Maria Wiklund, Lillemor Lundin-Olsson, Marlene Sandlund.

Background: Gait and balance impairment are typical symptoms of idiopathic normal pressure hydrocephalus (INPH), implicating that falls may afflict these patients., Objective: To investigate falls, related injuries, and associated psychological features, before and after shunt surgery for INPH and compared to the general population., Methods: The study included 176 patients shunted for INPH and 368 age- and sex-matched controls. Falls, fear of falling (FOF), fall-related injuries (mild-severe), confidence in avoiding falls (Swedish Falls Efficacy Scale (FES(S)), quality of life (QoL; EuroQoL 5-dimension 5 level instrument), and symptoms of depression (Geriatric Depression Scale 15) were investigated. Pre- and postoperative observational times were 12 mo before surgery and 21 mo after (mean). Recurrent fallers fell ≥2 times., Results: More INPH patients than controls were recurrent fallers (67% vs 11%; P < .001). They feared falling more often (FOF, mean ± standard deviation: 3.3 ± 1.1 vs 1.6 ± 0.9; P < .001) and had lower confidence in avoiding falls (FES(S) 78 ± 40 vs 126 ± 14; P < .001). After surgery, INPH patients improved in all parameters but they did not reach the levels of the controls. Among fallers there was no difference between patients and controls in the severity of injuries suffered. Low QoL and symptoms of depression were more common among recurrent fallers than one-time or nonfallers in both shunted patients and controls (P ≤ .001)., Conclusion: Falls, FOF, and low confidence in avoiding falls are considerable problems in INPH that may be reduced by shunt surgery. We suggest that remaining risk of falling and preventative measures are routinely considered in postoperative follow-ups and rehabilitation planning., (© Congress of Neurological Surgeons 2021.)

This perspective aims to highlight the lack of current knowledge on sarcopenic obesity in Africa and to call for diagnostic methods and appropriate interventions. Sarcopenic obesity has been defined as obesity that occurs in combination with low muscle mass and function, which is typically evident in older adults. However, there has been no clear consensus on population-specific diagnostic criterion, which includes both gold-standard measures that can be used in a more advanced health care system, and surrogate measures that can be used in low-income settings with limited resources and funding. Importantly, low and middle-income countries (LMICs) across Africa are in an ongoing state of economic and social transition, which has contributed to an increase in the aging population, alongside the added burden of poverty, obesity, and associated co-morbidities. It is anticipated that alongside the increased prevalence of obesity, these countries will further experience an increase in age-related musculoskeletal diseases such as sarcopenia. The developmental origins of health and disease (DOHaD) approach will allow clinicians and researchers to consider developmental trajectories, and the influence of the environment, for targeting high-risk individuals and communities for treatment and/or prevention-based interventions that are implemented throughout all stages of the life course. Once a valid and reliable diagnostic criterion is developed, we can firstly assess the prevalence and burden of sarcopenic obesity in LMICs in Africa, and secondly, develop appropriate and sustainable interventions that target improved dietary and physical activity behaviors throughout the life course., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Mendham, Lundin-Olsson, Goedecke, Micklesfield, Christensen, Gallagher, Myburgh, Odunitan-Wayas, Lambert, Kalula, Hunter and Brooks.)

Background: High rates of food insecurity, obesity and obesity-related comorbidities in ageing South African (SA) women may amplify the risk of developing sarcopenic obesity. This study aimed to investigate the prevalence and correlates of sarcopenic obesity and its diagnostic components [grip strength, appendicular skeletal muscle mass (ASM) and body mass index (BMI)] in older SA women from a low-income setting., Methods: This cross-sectional study recruited black SA women between the ages of 60-85 years (n = 122) from a low-income community. Testing included a fasting blood sample (markers of cardiometabolic risk, HIV), whole body and regional muscle and fat mass (dual-energy absorptiometry x-ray), anthropometry, blood pressure, functional movement tests, current medication use, demographic and health questionnaires, physical activity (PA; accelerometery), household food insecurity access scale, and a one-week quantified food frequency questionnaire. Foundation for the National Institutes of Health (FNIH) criteria (grip strength and ASM, adjusted for BMI) were used to classify sarcopenia. Participants with sarcopenia alongside a BMI of > 30.0 kg/m 2 were classified as having sarcopenic obesity. Prevalence using other criteria (European Working Group on Sarcopenia in Older People, Asian Working Group for Sarcopenia and the International Working Group for Sarcopenia) were also explored., Results: The prevalence of sarcopenia was 27.9%, which comprised of sarcopenia without obesity (3.3%) and sarcopenic obesity (24.6%). Other classification criteria showed that sarcopenia ranged from 0.8-14.7%, including 0.8-9.8% without obesity and 0-4.9% with sarcopenic obesity. Using multivariate-discriminant analysis (OPLS-DA) those with sarcopenic obesity presented with a descriptive profile of higher C-reactive protein, waist circumference, food security and sedentary time than women without sarcopenic obesity (p = 0.046). A similar profile described women with low BMI-adjusted grip strength (p < 0.001)., Conclusions: The majority of women with sarcopenia were also obese (88%). We show a large discrepancy in the diagnostic criteria and the potential for significantly underestimating the prevalence of sarcopenia if BMI is not adjusted for. The main variables common to women with sarcopenic obesity were higher food security, lower PA and chronic inflammation. Our data highlights the importance of addressing obesity within these low-income communities to ensure the prevention of sarcopenic obesity and that quality of life is maintained with ageing.

Background: Multidirectional walking, including backward walking, is integral to daily activities, and seems particularly challenging in older age, and in people with pathology affecting postural control such as dementia., Research Question: Does exercise influence backward walking speed in people with dementia, when tested using habitual walking aids and without, and do effects differ according to walking aid use?, Methods: This study included 141 women and 45 men (mean age 85 years) with dementia from the Umeå Dementia and Exercise (UMDEX), a cluster-randomized controlled trial study set in 16 nursing homes in Umeå, Sweden. Participants were randomized to a High-Intensity Functional Exercise (HIFE) program targeting lower limb strength-, balance and mobility exercise or to a seated attention control activity. Blinded assessors measured 2.4-meter usual backward walking speed, at baseline, 4 - (intervention completion) and 7-month follow-up; tested 1) with habitual walking aids allowed, and 2) without walking aids., Results: Linear mixed models showed no between-group effect in either backward walking speed test at 4 or 7 months; test 1) 0.005 m/s, P = .788 and -0.006 m/s, P = .754 and test 2) 0.030 m/s, P = .231 and 0.015 m/s, P = .569, respectively. In interaction analyses, exercise effects differed significantly between participants who habitually walked unaided compared with those that used a walking aid at 7 months (0.094 m/s, P = .027)., Significance: In this study of older people with dementia living in nursing homes, the effects of exercise had no overall effects on backwards walking speed. Nevertheless, some benefit was indicated in participants who habitually walked unaided, which is promising and merits further investigation in future studies., (Copyright © 2021 The Author(s).

Early detection of older adults with an increased risk of falling could enable early onset of preventative measures. Currently used fall risk assessment tools have not proven sufficiently effective in differentiating between high and low fall risk in community-living older adults. There are a number of tests and measures available, but many timed and observation-based tools are performed on a flat floor without interaction with the surrounding. To improve falls prediction, measurements in other areas that challenge mobility in dynamic conditions and that take a persons' own perception of steadiness into account should be further developed and evaluated as single or combined measures. The tools should be easy to apply in clinical practice or used as a self-assessment by the older adults themselves., Competing Interests: The authors have no conflict of interest., (Copyright: © 2020 Hylonome Publications.)

Background: Fall prevention exercise programmes are known to be effective, but access to these programmes is not always possible. The use of eHealth solutions might be a way forward to increase access and reach a wider population. In this feasibility study the aim was to explore the choice of programme, adherence, and self-reported experiences comparing two exercise programmes - a digital programme and a paper booklet., Methods: A participant preference trial of two self-managed fall prevention exercise interventions. Community-dwelling adults aged 70 years and older exercised independently for four months after one introduction meeting. Baseline information was collected at study start, including a short introduction of the exercise programme, a short physical assessment, and completion of questionnaires. During the four months intervention period, participants self-reported their performed exercises in an exercise diary. At a final meeting, questionnaires about their experiences, and post-assessments, were completed. For adherence analyses data from diaries were used and four subgroups for different levels of participation were compared. Exercise maintenance was followed up with a survey 12 months after study start., Results: Sixty-seven participants, with mean age 77 ± 4 years were included, 72% were women. Forty-three percent chose the digital programme. Attrition rate was 17% in the digital programme group and 37% in the paper booklet group (p = .078). In both groups 50-59% reported exercise at least 75% of the intervention period. The only significant difference for adherence was in the subgroup that completed ≥75% of exercise duration, the digital programme users exercised more minutes per week (p = .001). Participants in both groups were content with their programme but digital programme users reported a significantly higher (p = .026) degree of being content, and feeling supported by the programme (p = .044). At 12 months follow-up 67% of participants using the digital programme continued to exercise regularly compared with 35% for the paper booklet (p = .036)., Conclusions: Exercise interventions based on either a digital programme or a paper booklet can be used as a self-managed, independent fall prevention programme. There is a similar adherence in both programmes during a 4-month intervention, but the digital programme seems to facilitate long-term maintenance in regular exercise., Trial Registration: ClinTrial: NCT02916849.

Few studies have investigated the measurement error of the Mini-Mental State Examination (MMSE) in the same unit of measurement, also known as absolute reliability. This measurement can help determine whether an observed score change for an individual is likely to represent true change. The aim of this study was to investigate the absolute reliability of the MMSE among individuals with dementia that reside in nursing homes. Among 88 participants, 19 (21.6%) were men, 35 (39.8%) had Alzheimer's disease, 35 (39.8%) had vascular dementia, and the mean age was 84.0 years (range 65-98). The participants were tested and retested with the MMSE within 1-6 days. Both tests were administered by the same assessor at the same time of day. The mean MMSE score was 13.7 (range 0-28). The absolute difference between MMSE scores varied from 0 to 6 points, and the differences did not correlate with the corresponding score means ( p  = 0.874). The smallest detectable change (SDC) between two measurements was 4.00. The SDC was independent of depression, impaired vision and hearing, delirium within the last week, dementia type and age. However, the SDC was 5.56 among men and 3.50 among women ( p  = 0.003). In conclusion, for individuals with dementia that reside in nursing homes, it seems like their MMSE score needs to change by four or more points between two measurements in order for their score change to be reliably higher than the measurement error., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest., (© The Author(s) 2020.)

Objectives: Previous research has shown that balance and gait difficulties are predictors of falls. The aim of this study was to evaluate the predictive validity of two tools reporting on balance and gait among older community-living adults independent in personal activities of daily living (p-ADL)., Methods: Prospective study design. Baseline assessment included the Timed Up and Go test (TUG) and the Short Physical Performance Battery (SPPB). Following baseline, falls were recorded monthly for one year by 202 participants (70.1% women) who were independent in p-ADL, and at least 75 years old (79.2±3.5). ROC-curves were made and AUC were calculated., Results: Forty-seven percent of the participants reported falls. AUCs calculated for TUG were 0.5 (95%CI: 0.5-0.6) for those with at least one fall, and 0.5 (95% CI: 0.5-0.6) for recurrent fallers. Corresponding figures for SPPB were 0.5 (95% CI: 0.5-0.6) and 0.5 (95% CI: 0.5-0.6)., Conclusion: This study does not support a recommendation to use the Timed Up and Go test or the Short Physical Performance Battery as tools for the identification of fall-prone persons among older adults living in the community. These results reinforce the need for further research into appropriate tools for identifying independent but fall-prone older adults., Competing Interests: The authors have no conflict of interest., (Copyright: © 2020 Hylonome Publications.)

Introduction: Exercise interventions have a strong evidence base for falls prevention. However, exercise can be challenging to implement and often has limited reach and poor adherence. Digital technology provides opportunities for both increased access to the intervention and support over time. Further knowledge needs to be gained regarding the effectiveness of completely self-managed digital exercise interventions. The main objective of this study is to compare the effectiveness of a self-managed digital exercise programme, Safe Step, in combination with monthly educational videos with educational videos alone, on falls over 1 year in older community-dwelling adults., Methods and Analysis: A two-arm parallel randomised controlled trial will be conducted with at least 1400 community-living older adults (70+ years) who experience impaired balance. Participants will be recruited throughout Sweden with enrolment through the project website. They will be randomly allocated to either the Safe Step exercise programme with additional monthly educational videos about healthy ageing and fall prevention, or the monthly education videos alone. Participants receiving the exercise intervention will be asked to exercise at home for at least 30 min, 3 times/week with support of the Safe Step application. The primary outcome will be rate of falls (fall per person year). Participants will keep a fall calendar and report falls at the end of each month through a digital questionnaire. Further assessments of secondary outcomes will be made through self-reported questionnaires and a self-test of 30 s chair stand test at baseline and 3, 6, 9 and 12 months after study start. Data will be analysed according to the intention-to-treat principle., Ethics and Dissemination: Ethical approval was obtained by The Regional Ethical Review Board in Umeå (Dnr 2018/433-31). Findings will be disseminated through the project web-site, peer-reviewed journals, national and international conferences and through senior citizen organisations' newsletters., Trial Registration Number: NCT03963570., Competing Interests: Competing interests: The authors declare that they have no competing interest besides that DAS is a Director of Later Life Training, a not for profit training company in the UK that delivers group falls prevention exercise training (Otago and FaME) to health and fitness professionals. The App was developed collaboratively and it will not be sold for profit., (© Author(s) (or their employer(s)) 2020. Re-use permitted under CC BY. Published by BMJ.)

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., (Copyright © 2018 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Background: Exercise is effective in order to prevent falls in community-dwelling older people. Self-management programs have the potential to increase access and reduce costs related to exercise-based fall prevention. However, information regarding older people's views of participating in such programs is needed to support implementation. The aim of this study was to explore older people's experiences of a self-management fall prevention exercise routine guided either by a digital program (web-based or mobile) or a paper booklet., Methods: This qualitative study was part of a feasibility study exploring two completely self-managed exercise interventions in which the participants tailored their own program, guided either by a digital program or a paper booklet. Individual face-to-face semi-structured interviews were conducted with a purposeful sample of 28 participants (18 women), mean age 76 yrs. Qualitative content analysis was used to analyse the data., Results: Self-managing and self-tailoring these exercise programs was experienced as 'Managing pieces of a personal puzzle'. To independently being able to create a program and manage exercise was described in the categories 'Finding my own level' and 'Programming it into my life'. The participants experienced the flexibility and independence provided by completely self-managed exercise as positive and constructive although it required discipline. Furthermore, different needs and preferences when managing their exercise were described, as well as varying sources of motivation for doing the exercise, as highlighted in the category 'Defining my source of motivation'. The category 'Evolving my acquired knowledge' captures the participants' views of building their competence and strategies for maintenance of the exercise. It describes a combined process of learning the program and developing reflection, which was more clearly articulated by participants using the digital program., Conclusions: This study provides new knowledge regarding experiences, preferences and motivations of older people to engage in home-based self-managed fall prevention exercise. They expressed both a capability and willingness to independently manage their exercise. A digital program seems to have strengthened the feeling of support while creating their own exercise program and tailoring it to their preferences and circumstances, which might therefore create better opportunities for adoption and adherence in the long term.
