“…Finally, vestibular changes often induce problems with balance and postural control, which makes avoiding obstacles more difficult and increases the risk of falling. To counteract such deficits, older adults often employ more conservative adaptation strategies by taking slow, short and more frequent steps (Caetano et al, 2016) and by prioritizing walking control over concurrent cognitive tasks (Simieli et al, 2015). As a consequence, a reduced amount of attentional resources can be allocated to keeping track of both self-motion and environmental cues, ultimately resulting in reduced navigation performance.…”

“…Notably, controls without specific disorders also experienced falls (23.3%). A decreased walking ability in older adults compared to younger adults has been demonstrated [33], both in steady-state walking and walking adaptability. Assessing limitations in walking ability, regardless of their cause (e.g., neurological disorders, ageing), thus likely provides a better indication of someone's fall risk.…”

Background: Most falls occur during walking and are due to trips, slips or misplaced steps, which suggests a reduced walking adaptability. The objective of this study was to evaluate the potential merit of a walkingadaptability assessment for identifying prospective fallers and risk factors for future falls in a cohort of stroke patients, Parkinson's disease patients, and controls (n = 30 for each group).Research question: Does an assessment of walking-adaptability improve the identification of fallers compared to generic fall-risk factors alone?Methods: This study comprised an evaluation of subject characteristics, clinical gait and balance tests, a quantitative gait assessment and a walking-adaptability assessment with the Interactive Walkway. Subjects' falls were registered prospectively with falls calendars during a 6-month follow-up period. Generic and walkingrelated fall-risk factors were compared between prospective fallers and non-fallers. Binary logistic regression and Chi-square Automatic Interaction Detector analyses were performed to identify fallers and predictor variables for future falls.Results: In addition to fall history, obstacle-avoidance success rate and normalized walking speed during goaldirected stepping correctly classified prospective fallers and were predictors of future falls. Compared to the use of generic fall-risk factors only, the inclusion of walking-related fall-risk factors improved the identification of prospective fallers.Significance: If cross-validated in future studies with larger samples, these fall-risk factors may serve as quick entry tests for falls prevention programs. In addition, the identification of these walking-related fall-risk factors may help in developing falls prevention strategies. Methods Subjects30 stroke patients, 30 PD patients and 30 controls participated in this study (Table 1). Groups were age-and sex-matched. Patients were https://doi.

“…Essas estratégias são caracterizadas por velocidade mais lenta, devido à diminuição no tamanho da passada, que aumenta a base de suporte e o tempo de permanência na fase de duplo apoio, abreviando o tempo de permanência na fase de oscilação, período de mais instabilidade. 19 Nessa perspectiva, ressalta-se o estudo desenvolvido com 60 idosos (≥65 anos) da comunidade no município de Natal (Rio Grande do Norte, Brasil), que analisou a capacidade da VM em identificar idosos com medo de cair. A VM foi avaliada segundo o fenótipo da fragilidade e o medo de cair mediante a Falls Eficacy Scale -International (FES-I).…”

Objetivo: analisar a relação entre a velocidade da marcha e a ocorrência de quedas em idosos longevos. Método: estudo transversal realizado com 243 idosos longevos (≥80 anos), usuários da atenção primária à saúde. A coleta de dados ocorreu nos domicílios dos participantes, mediante aplicação de questionário sociodemográfico e clínico e teste de velocidade da marcha. Realizaram-se análises descritivas e teste de associação entre variáveis (qui-quadrado), consideraram-se os valores de p≤0,05 estatisticamente significativos. Resultados: dos 243 longevos, 111 (45,7%) relataram quedas nos últimos 12 meses, 50 (20,6%) velocidade da marcha reduzida e, destes, 30 (60%) caíram no último ano. Entre os idosos com velocidade da marcha reduzida, houve predomínio do sexo feminino (n=33; 66%) e média de idade 86,24 anos (±4,64). A velocidade da marcha reduzida mostrou associação significativa com a ocorrência de quedas nos últimos 12 meses (p=0,023). Conclusão: a redução da velocidade da marcha em longevos mostra relação ao episódio de quedas, o qual esteve presente em mais da metade dos longevos com velocidade da marcha reduzida.

ABSTR ACT Objetivo: to analyze the relationship between gait speed and fall occurrence in long-lived elderly. Method: a cross-sectional study with 243 long-lived elderly (≥80 years old), primary health care users. Data collect took place in the residences of the participants, using a socio-demographic and clinical questionnaire and a gait speed test. Descriptive analyses and an association test were performed among the variables (chi-square), the p≤0.05 values were considered statistically significant. Results: among the 243 long-lived elderly, 111 (45.7%) reported falls in the last 12 months, 50 (20.6%) reduced gait speed and 30 (60%) of these fell in the last year. Among the elderly with reduced gait speed, there was a female gender predominance (n = 33; 66%) and mean age 86.24 years old (± 4.64). The reduced gait speed showed a significant association with fall occurrence in the last 12 months (p = 0.023). Conclusion: the reduction of gait speed in long-lived elderly shows relationship with the fall episode, which was present in more than half of the long-lived elderly with reduced gait speed.
