The use of virtual reality through exergames or active video game, i.e. a new form of interactive gaming, as a complementary tool in rehabilitation has been a frequent focus in research and clinical practice in the last few years. However, evidence of their effectiveness is scarce in the older population. This review aim to provide a summary of the effects of exergames in improving physical functioning in older adults. A search for randomized controlled trials was performed in the databases EMBASE, MEDLINE, PsyInfo, Cochrane data base, PEDro and ISI Web of Knowledge. Results from the included studies were analyzed through a critical review and methodological quality by the PEDro scale. Thirteen studies were included in the review. The most common apparatus for exergames intervention was the Nintendo Wii gaming console (8 studies), followed by computers games, Dance video game with pad (two studies each) and only one study with the Balance Rehabilitation Unit. The Timed Up and Go was the most frequently used instrument to assess physical functioning (7 studies). According to the PEDro scale, most of the studies presented methodological problems, with a high proportion of scores below 5 points (8 studies). The exergames protocols and their duration varied widely, and the benefits for physical function in older people remain inconclusive. However, a consensus between studies is the positive motivational aspect that the use of exergames provides. Further studies are needed in order to achieve better methodological quality, external validity and provide stronger scientific evidence.Electronic supplementary materialThe online version of this article (doi:10.1186/1743-0003-11-156) contains supplementary material, which is available to authorized users.

ResumoObjetivo: Identificar a prevalência e os fatores associados a quedas e quedas recorrentes em uma amostra de idosos que vivem na comunidade no município de Cuiabá-MT. Métodos: Estudo transversal, de base populacional, com idosos de 65 anos ou mais. Os domicílios foram arrolados por meio do sorteio de regiões censitárias, de acordo com a densidade populacional e o número de idosos em cada região. Foi utilizado um inquérito multidimensional contendo dados sociodemográficos, clínicos, psicológicos, de desempenho funcional e uma bateria de testes físicos. Resultados: A amostra foi composta por 391 participantes, com idade média (dp) de 72,4 (6,0) anos. Do total de participantes, 37,5% referiram ter caído no último ano e 16,5% relataram duas ou mais quedas. Cair foi associado a sintomas depressivos (OR=1,96; 95% IC 1,22-3,14, p=0,005); morar só (OR=2,83; 95% IC 1,57-5,12, p<0,001); baixa autoeficácia para quedas (OR=1,77; 95% IC 1,10-2,83, p=0,017); e artrite (OR= 2,10; 95% IC 1,34-3,29, p=0,001). Cair recorrentemente foi associado a: gênero feminino (OR=2,54; 95% IC 1,23-5,21, p=0,011); ter 80 anos e mais (OR=2,30; 95% IC 1,12-4,72, p=0,022); queixa de tontura (OR=1,91; 95% IC 1,04-3,49, p=0,035); morar só (OR=2,57; 95% IC 1,18, p=0,008); artrite (OR=1,94; 95% IC 1,51, p=0,027); e sintomas depressivos (OR=2,13 95% IC 1,88, p=0,013). Conclusão: Os fatores associados a quedas e quedas recorrentes modificáveis foram morar só, ter sintomas depressivos, baixa autoeficácia para quedas, tontura e artrite. Sugere-se que esses fatores sejam considerados em programas de prevenção de quedas nesta população.

BackgroundDizziness is a common complaint among older adults and has been linked to a wide range of health conditions, psychological and social characteristics in this population. However a profile of dizziness is still uncertain which hampers clinical decision-making. We therefore sought to explore the relationship between dizziness and a comprehensive range of demographic data, diseases, health and geriatric conditions, and geriatric syndromes in a representative sample of community-dwelling older people.MethodsThis is a cross-sectional, population-based study derived from FIBRA (Network for the Study of Frailty in Brazilian Elderly Adults), with 391 elderly adults, both men and women, aged 65 years and older. Elderly participants living at home in an urban area were enrolled through a process of random cluster sampling of census regions. The outcome variable was the self-report of dizziness in the last year. Several feelings of dizziness were investigated including vertigo, spinning, light or heavy headedness, floating, fuzziness, giddiness and instability. A multivariate logistic regression analysis was conducted to estimate the adjusted odds ratios and build the probability model for dizziness.ResultsThe complaint of dizziness was reported by 45% of elderly adults, from which 71.6% were women (p=0.004). The multivariate regression analysis revealed that dizziness is associated with depressive symptoms (OR = 2.08; 95% CI 1.29–3.35), perceived fatigue (OR = 1.93; 95% CI 1.21-3.10), recurring falls (OR = 2.01; 95% CI 1.11-3.62) and excessive drowsiness (OR = 1.91; 95% CI 1.11–3.29). The discrimination of the final model was AUC = 0.673 (95% CI 0.619-0.727) (p< 0.001).ConclusionsThe prevalence of dizziness in community-dwelling elderly adults is substantial. It is associated with other common geriatric conditions usually neglected in elderly adults, such as fatigue and drowsiness, supporting its possible multifactorial manifestation. Our findings demonstrate the need to expand the design in future studies, aiming to estimate risk and identify possible causal relations.

Unfavorable general health conditions did not affect the assessment of work ability or most of the tests of physical functional capacity in the aging group.

Object: to examine the characteristics to the last fall of Brazilian elderly persons who experienced falls in 2008 and 2009, and to identify if there is a relationship with sociodemographic characteristics, physical health, comorbidities, clinical conditions and the circumstances of the falls. Methods: a cross-sectional, population based study was carried out with participants aged 65 and older from Barueri in the state of São Paulo and Cuiabá in the state of Mato Grosso, Brazil. Households were enrolled within each census region according to population density and the number of elderly persons living in each region. A multidimensional questionnaire composed of sociodemographic factors and data regarding falls was used. Associations were analyzed using contingency tables, and Fisher's Exact or Pearson's Chi-square test was used. Results: 774 elderly people were included in the study, 299 of whom reported falling in the previous year. Of these, 176 (58.9%) had fallen once and 123 (41.1%) reported having fallen twice or more. Among fallers the mean age was 72.53 (±6.12) years and 214 (71.6%) were female. About 107 (35.8%) of the elderly reported having fallen forwards, 79 (26.4%) fell to the side and 42(14%) fell backwards. Regarding the circumstances of the falls, 107 (35.8%) reported having lost their balance, 79 (26.4%) said they had stumbled and 42 (14%) said they had slipped. There was an association between the mechanism and circumstances of the falls and having fallen once or twice or more. There was an association between the circumstances of falls and the number of medications taken. Conclusion: The characteristics of falls were different among elderly persons who had fallen once or twice or more, which may guide health professionals, the elderly and their families in relation to specific fall prevention strategies.

This systematic review examines the association between physical activity (PA) level and risk of falling in community-dwelling older adults. A search of PubMed, Embase, CINAHL, SPORTDiscus, and Web of Science was performed in January 2017. Four prospective cohort studies investigating the incidence of falls in a period of at least 12 months and its association with the level of PA in people aged 60 years and older were reviewed and pooled for meta-analysis. The pooled risk ratio (RR) for being a recurrent faller (2,420 participants) was 39% higher among those who were in the lowest PA level (RR = 1.39; 95% confidence interval [1.17, 1.65]; I = 0%, p = .43; p < .0001). The association between being a faller (7,927 participants) and PA level was inconclusive. This review identified that the benefit of general PA for preventing falls is associated with the adopted PA level.

Dizziness is a common complaint among older adults. Aim To identify the prevalence of dizziness and its related factors in a sample of community-dwelling older adults. Methods A prospective population-based study with a representative sample of older adults aged 65 years and over. A multidimensional questionnaire and a battery of measures were used for assessing physical function. Results The prevalence of dizziness was 45%. Vertigo was found in 70.4% of older adults with dizziness and 43.8% of them referred vertigo crises along life. A significant association was found between dizziness and female gender ( p =0.004), memory difficulties complaints ( p =0.015), bad health perception ( p =0.001), depression ( p <0.0001), five or more comorbidities ( p =0.021), self-reported fatigue ( p <0.0001), recurrent falls ( p =0.001), excessive sleepiness ( p =0.003), fear of falling ( p <0.0001), left leg unipedal stance ( p =0.002) and Short Performance Physical Battery score ( p =0.009). Conclusion Dizziness is a common complaint among older adults and it is associated with limiting clinical conditions, such as depression, fatigue, excessive sleepiness and impaired memory. It is highlighted the association between dizziness and recurrent falls, fear of falling and lower performance in physical function tests, which can restrict independence. These data suggest the importance of a multifactorial approach to dizziness in older adults.

BackgroundHip fractures resulting from falls increase substantially with advancing age and less than half of older hip fracture survivors regain their former levels of mobility. There is increasing evidence that rehabilitation interventions with exercises that goes beyond the sub-acute phase or even in a later stage of care have a positive impact on various functional abilities. The purpose of this study is to determine if exercise program training for people who have suffered a fall-related hip fracture will improve functional mobility when compared with usual care.MethodsA randomized controlled trial with blinded assessors and intention-to-treat analysis will be undertaken. We will recruit 82 older adults, 60 years or over who have suffered a hip fracture due to a fall in the previous 6 to 24 months. Participants randomized to the Intervention Group (IG) will undertake a physical exercise program involving progressive and challenging balance training and neuromuscular and functional training of the lower limbs, conducted at home by physiotherapists, once a week, lasting about one hour, in the first, second and third month after randomization and will be taught to perform exercises at home, twice a week, using a booklet. Visits to monitor and progress the home exercise program will be conducted once a month, from the fourth to the sixth month and each 2 months until the end of the follow up at the 12th month, i.e., a total of 18 sessions. Participants will receive monthly phone calls to encourage exercise adherence. The control group will receive usual care. The primary outcome will be mobility-related disability and participants will be assessed at baseline, and at 3 months, 6 and 12 months. Participants will receive monthly phone calls to ask about falls and exercise adherence. Adverse effects will be monitored.DiscussionThis study proposes a home-based exercise program, which may in part overcome some barriers for rehabilitation, such as difficulties with public transportation and lack of a caregiver to accompany older patients to sessions. If a positive effect is observed this program has the potential to be incorporated into the public health system and contribute to building a pathway of care for older people with hip fracture.Trial registrationClinicaltrials.gov Identifier: NCT02295527.
