Abstract Context Aging causes a progressive worsening in postural balance, affecting functional independence and increasing the risk of falls. Objective The aim of the study was to evaluate the effect of aging on the static balance in women from 50-years to 89-years of age. Design This was a cross-sectional study, with 400 irregularly active women were evaluated and grouped by age: Group 6thdecade (age 50 to 59) ‒ 58 participants; Group 7thdecade (age 60 to 69) ‒ 214 participants; Group 8thdecade (age 70 to 79) ‒ 92 participants; Group 9thdecade (age 80 to 89) ‒ 36 participants. Postural balance was evaluated using a portable force platform in a standard standing position, with Eyes Open (EO) and Eyes Closed (EC). Results In the two measurement conditions, the elderly women in Group 9thdecade presented mediolateral displacement and range, and mean velocity greater than the women's values in Groups 6thand 7thdecade. In the EO e EC situation, the displacement was higher in the elderly Group 9thdecade compared to younger groups. Group 8thhas a mean velocity greater than Group 6thdecade in the EO situation. Conclusions Posturography showed a decline in postural balance with advancing age, suggesting that the 9thdecade of life is a borderline age to this detriment due to an increase in postural instability.

OBJECTIVE: This study aimed to evaluate if posturography can be considered a recurrent fall predictor in elderly individuals. METHODS: This was a cross-sectional study. A total of 124 subjects aged 60 to 88 years were evaluated and divided into two groups—the recurrent fallers (89) and single fallers (35) groups. Patients’ sociodemographic characteristics were assessed, and clinical testing was performed. The functional test assessment instruments used were timed up and go test (TUGT), Berg Balance Scale (BBS), five times sit-to-stand test, and Falls Efficacy Scale (to measure fear of falling). Static posturography was performed in a force platform in the following three different situations—eyes open (EO), eyes closed (EC), and EO dual task. RESULTS: There were significant differences between the single and recurrent fallers groups regarding the fear of falling, the Geriatric Depression Scale score, the mean speed calculated from the total displacement of the center point of pressure (COP) in all directions with EO, and the root mean square of the displacement from the COP in the mediolateral axis with EC. Based on the hierarchical logistic regression model, none of the studied posturographic variables was capable of significantly increasing the power of differentiation between the recurrent and single fallers groups. Only TUGT with a cognitive distractor (p<0.05) and the BBS (p<0.01) presented with significant independent predictive power. CONCLUSION: TUGT with a cognitive distractor and the BBS were considered recurrent fall predictors in elderly fallers.

Introdução: Quedas são um problema clínico comum nos idosos, que pode reduzir sua mobilidade e independência. O uso de instrumentos simples para detecção do risco de quedas é fundamental para prevenção e tratamento de tais eventos. Não há, porém, consenso quanto aos testes mais adequados para cada situação. Objetivo: Revisar estudos sobre eficácia, sensibilidade e especificidade dos testes Timed Up and Go Test e Berg Balance Scale, a fim de verificar qual é o mais apropriado para predizer quedas em idosos. Métodos: Realizou-se revisão bibliográfica nas bases de dados MEDLINE, PubMed, ISI, LILACS e Portal de Periódicos CAPES, entre os anos de 2001 e 2011. Resultados: Foram selecionados 37 artigos, sendo 17 sobre a Berg Balance Scale e 20 sobre o Timed Up and Go Test. A revisão mostrou que os dois testes podem ser bons preditores de quedas, mas os artigos diferiram quanto à definição de queda e caidor, tipo de estudo, quantidade e característica da amostra e avaliação de quedas, levando a diferentes resultados quanto a nota de corte, sensibilidade, especificidade e predição de quedas. Há controvérsias quanto à capacidade de predição em perfis específicos, como os idosos ativos. Conclusão: Os testes avaliados são eficazes para predição de quedas, desde que adaptados para cada perfil. Novos estudos devem ser realizados com metodologia homogênea, a fim de favorecer a comparação de resultados sobre a eficácia desses testes.

Introduction: Fall is a common problem in the elderly and it can reduce their mobility and independence. The use of simple tools to detect risk of falls is essential to prevent and treat such events. However, there is no consensus about the most appropriate tools for each situation. Objective: To review studies about efficacy, sensitivity and specificity of Timed Up and Go Test (TUGT) and Berg Balance Scale (BBS) in order to ascertain which is the most appropriate to predict falls in the elderly. Methods: We performed a literature review from MEDLINE, PubMed, ISI, LILACS and Portal de Periódicos CAPES databases, between 2001 and 2011. Results: We selected 17 different articles about BBS and 20 articles about TUGT. The review showed the two tools can be good predictors of falls. However, the articles differed in definition of fall and faller, type of study, quantity and characteristics of sample and assessment of falls, leading to different results as cutoff scores, sensitivity, specificity and prediction of fall. There is controversy about the ability of tools to predict falls in specific samples, such as active elderly. Conclusion: TUGT and BBS are effective to predict falls, provided they are adapted to each sample. Further studies should be performed using articles with homogeneous methods in order to support comparison of results about the effectiveness of tools.
