Abstract

BACKGROUND

Older adults with lower-limb amputations (LLAs) often experience lack of confidence and poor balance, which limits their mobility. There are few validated measures for assessing these outcomes in the LLA population.

OBJECTIVES

To assess the validity of the Life Space Assessment (LSA) and the Physical Activity Scale for the Elderly (PASE) for older adults with LLA.

STUDY DESIGN

Secondary analyses of cross-sectional data.

METHODS

Sixty-eight older adults with LLA across Canada were recruited to complete the LSA and the PASE. Validity was assessed via correlations with the Activities-specific Balance Confidence (ABC), Four-Square Step Test (FSST), and Two-Minute Walk Test (2-MWT).

RESULTS

As hypothesized, the LSA was positively correlated with the ABC (ρ = 0.36, 95% confidence interval [CI] [0.17, 0.62]) and 2-MWT (r = 0.49, 95% CI [0.27, 0.70]) and negatively correlated with FSST (ρ = -0.39, 95% CI [-0.56, -0.10]). The PASE was positively correlated with the ABC (ρ = 0.34, 95% CI [0.10, 0.56]) and 2-MWT (ρ = 0.32, 95% CI [0.05, 0.52]), and negatively correlated with FSST (ρ = -0.36, 95% CI [-0.53, -0.07]).

CONCLUSIONS

The LSA has validity in measuring life space mobility. The PASE captures the physical activity with weaker support of validity in older adults with LLA.

CLINICAL RELEVANCE

The LSA and PASE are quick low-cost tools for clinicians to assess mobility-related functional health and physical activity, respectively, in older adults with LLA. However, the PASE may contain activities that are not common among older adults with LLA.

摘要

背景

下肢截肢（LLA）的老年人常因缺乏信心和平衡感差而导致活动受限。目前针对LLA 人群，缺乏评估这些结果的有效测量方法。

目的

评估生活空间评估（LSA）和老年人体育活动量表（PASE）在LLA 老年人中的有效性。

研究设计

横截面数据的二次分析。

方法

在加拿大招募了 68 名 LLA 老年人完成 LSA 和 PASE。通过与活动特异性平衡信心量表（ABC）、四方步测试（FSST）和两分钟步行测试（2-MWT）的相关性评估有效性。

结果

与假设一致，LSA 与 ABC（ρ=0.36，95%置信区间 [CI] [0.17，0.62]）和 2-MWT（r=0.49，95% CI [0.27，0.70]）呈正相关，与 FSST（ρ=-0.39，95% CI [-0.56，-0.10]）呈负相关。PASE 与 ABC（ρ=0.34，95% CI [0.10，0.56]）和 2-MWT（ρ=0.32，95% CI [0.05，0.52]）呈正相关，与 FSST（ρ=-0.36，95% CI [-0.53，-0.07]）呈负相关。
