“…It is always a point of discussion whether a smaller [17] or a larger [24] toe clearance elicits risk of obstacle contacts, and it has been argued that an obstacle contact leading to a trip commonly results from insufficient foot clearance. The insufficient clearance may come from the fact that perhaps people who know what they are doing have small clearance and higher confidence, and people who are insecure have large clearance but low confidence, causing them to hit the obstacle.…”

“…The kinematic measures related to fall risk investigated in the present study were: average gait speed along the 8-m walkway, toe clearance in leading limb (LL) and trailing limb (TL) (vertical distance between the hallux and the obstacle, measured when the hallux was at the lowest horizontal distance from the obstacle marker), step length in LL and TL (measured during the crossing stride only), LL heel clearance (vertical distance between the heel and the obstacle, determined at the instant that the heel was at the lowest horizontal distance from the obstacle marker), pre-obstacle horizontal distance (horizontal distance between hallux and obstacle before crossing), and postobstacle horizontal distance (horizontal distance between heel and obstacle after crossing), as determined in a previous study [17].…”

Purpose. Many falls in older people occur after tripping or slipping, mainly due to unsuccessful vertical clearances or horizontal distances. A first fall may be explained by several factors related to aging and can be a trigger to subsequent falls. It is unclear if a history of fall changes the kinematics of obstacle crossing, increasing the risk of trips. Here, we determined whether older women reporting a fall history showed different spatial-temporal kinematic parameters during obstacle crossing than non-fallers. In addition, we investigated the presence of asymmetries between the preferred and non-preferred lower limb during obstacle crossing in fallers and non-fallers. Methods. This cross-sectional study recruited older women with a history of fall (n = 10) and without falls (n = 10). They had their kinematic parameters evaluated when walking at self-selected speed along an 8-m walkway, crossing an obstacle positioned in the middle of the walkway, with both preferred and non-preferred limb as the lead limb. The groups were compared, and effects of lower limb preference were also determined in both groups. Results. No main effects of group were observed regarding the kinematic variables. An effect of leg preference was found for post-obstacle horizontal distance, which was greater for the preferred limb in both groups. Conclusions. In conclusion, the kinematics of gait with obstacle crossing does not differentiate between older women with or without a history of recent fall.

The association between balance and free-living physical activity in an older community-dwelling adult population: a systematic review and meta-analysis

BackgroundPoor balance is associated with an increased risk of falling, disability and death in older populations. To better inform policies and help reduce the human and economic cost of falls, this novel review explores the effects of free-living physical activity on balance in older (50 years and over) healthy community-dwelling adults.MethodsSearch methods: CENTRAL, Bone, Joint and Muscle Trauma Group Specialised register and CDSR in the Cochrane Library, MEDLINE, EMBASE, CINAHL, PsychINFO, and AMED were searched from inception to 7th June 2016.Selection criteria: Intervention and observational studies investigating the effects of free-living PA on balance in healthy community-dwelling adults (50 years and older).Data extraction and analysis: Thirty studies were eligible for inclusion. Data extraction and risk of bias assessment were independently carried out by two review authors. Due to the variety of outcome measures used in studies, balance outcomes from observational studies were pooled as standardised mean differences or mean difference where appropriate and 95% confidence intervals, and outcomes from RCTs were synthesised using a best evidence approach.ResultsLimited evidence provided by a small number of RCTs, and evidence from observational studies of moderate methodological quality, suggest that free-living PA of between one and 21 years’ duration improves measures of balance in older healthy community-dwelling adults. Statistical analysis of observational studies found significant effects in favour of more active groups for neuromuscular measures such as gait speed; functionality using Timed Up and Go, Single Leg Stance, and Activities of Balance Confidence Scale; flexibility using the forward reach test; and strength using the isometric knee extension test and ultrasound. A significant effect was also observed for less active groups on a single sensory measure of balance, the knee joint repositioning test.ConclusionThere is some evidence that free-living PA is effective in improving balance outcomes in older healthy adults, but future research should include higher quality studies that focus on a consensus of balance measures that are clinically relevant and explore the effects of free-living PA on balance over the longer-term.Electronic supplementary materialThe online version of this article (10.1186/s12889-018-5265-4) contains supplementary material, which is available to authorized users.

Artigo originAl Original article artículO Original RESUMOIntrodução: O envelhecimento desencadeia alterações da marcha e aumenta o risco de quedas e o medo de cair, comprometendo a saúde e a capacidade funcional do idoso. Estudos anteriores investigaram a prática de exercício físico como possível fator de redução desses problemas, porém os resultados encontrados até o momento são inconclusivos. Objetivo: Analisar os parâmetros da marcha, a prevalência de quedas e o medo de cair em idosas ativas e sedentárias. Métodos: Trinta e cinco mulheres com idades entre 60 e 75 anos foram divididas em dois grupos: grupo sedentárias (GS), que não praticavam exercícios físicos regularmente no último ano e grupo ativas (GA), que praticavam exercício físico em um projeto de extensão de uma universidade pública, há pelo menos seis meses. Os dados referentes aos parâmetros espaço-temporais da marcha foram coletados por meio de um tapete (4,88 m) com sensores de pressão. As idosas caminharam sobre o tapete em duas condições experimentais: velocidade preferida e maior velocidade possível. Foram realizadas três tentativas em cada condição de forma aleatória, totalizando seis tentativas. As voluntárias também responderam dois questionários: questionário de Baecke, para avaliar a aptidão física, e questionário de quedas para avaliar a ocorrência e consequências das quedas. Resultados: A velocidade da marcha, a cadência, e o comprimento da passada foram significativamente maiores nas idosas ativas, enquanto o tempo em duplo suporte foi significativamente maior nas idosas sedentárias em ambas as condições analisadas. Além disso, as idosas ativas apresentaram menor prevalência de quedas (22%) e de medo de cair (22%) comparadas às idosas sedentárias (58% e 70%, respectivamente). Conclusão: A prática de exercícios físicos realizados de forma sistemática em programas de educação física para idosos parece ser uma estratégia interessante para minimizar os efeitos do processo de envelhecimento na marcha, no risco de quedas e no medo de cair em mulheres idosas.Descritores: envelhecimento; atividade motora; exercício; caminhada.
