Background

The Functional Gait Assessment (FGA) is a standardized instrument for assessing postural stability during various walking tasks. It was developed to increase the reliability and to decrease the potential ceiling effect observed with the Dynamic Gait Index (DGI).

Objective

To translate and cross-culturally adapt the FGA into Portuguese-Brazilian, and to evaluate its reliability in community-dwelling Brazilian older adults.

Methods

The process of translation and cross-cultural adaptation followed the recommendations of international guidelines. The pre-final version was applied to a sample of 55 older adults of both sexes living independently in the community. For the assessment of reliability (i.e. inter- and intra-rater reliability, standard error of measurement (SEM), and internal consistency), 70 older adults aged 60–87 years were evaluated.

Results

There was a conceptual equivalence between the original and the translated versions. All FGA items that used measurements in inches and feet were modified to use matching values in centimeters to reflect the measurement unit used in Brazil. The FGA-Brazil showed excellent inter- and intra-rater reliability (ICC2,1 > 0.90), low SEM (ranging from 1.03 to 1.52), and good internal consistency (Cronbach’s alpha = 0.858).

Conclusion

The FGA-Brazil is a semantically and linguistically valid and reliable instrument to assess walking balance among community-dwelling older adults.

巴西老年人的跨文化适应和功能步态评估的可靠性。

背景

功能步态评估(FGA)是用于评估各种步行任务期间姿势稳定性的标准化工具。它的开发是为了提高可靠性并降低动态步态指数(DGI)所观察到的潜在天花板效应。

目的

将FGA进行翻译和跨文化调整以适应葡萄牙语-巴西语,并评估其在居住于社区的巴西老年人中的可靠性。

方法

翻译和跨文化适应过程遵循国际准则的建议。最终版本适用于55个男女独立生活在社区中的老年人样本。为了评估可靠性(即评定者之间和评定者内部的可靠性,标准测量误差(SEM)和内部一致性),对70位60-87岁的老年人进行了评估。

结果

原始版本和翻译版本在概念上是等效的。所有使用英寸和英尺进行测量的FGA项目都经过修改,以使用以厘米为单位的匹配值来反映巴西使用的测量单位。FGA-Brazil显示出极高的评分者之间和评分者内部可靠性(ICC 2,1 > 0.90),较低的SEM(范围从1.03至1.52)和良好的内部一致性(Cronbach's alpha = 0.858)。

结论

FGA-Brazil是一种语义和语言上有效且可靠的工具,可用来评估社区居民中老年人的步行平衡。
