Functional limitations in stroke survivors are sometimes associated with fatigue. This study assessed the functional limitations due to fatigue in community-dwelling stroke survivors undergoing physiotherapy. The differences in functional limitations due to fatigue were determined between sexes, stroke types, sides of affectation, age categories and levels of disability. Relationships between functional limitation due to fatigue and these variables were also determined.
This was a cross-sectional study involving 63 stroke survivors (35 male survivors and 28 female survivors) with ages ranging from 45 to 79 years (mean = 53.68 ± 10.95 years). Functional limitation due to fatigue was assessed with the modified fatigue impact scale (MFIS). Modified Rankin scale was used to categorize the disability of the participants. Data were analysed using descriptive (mean, standard deviation, percentage and frequency) and inferential (Mann-Whitney U-test and Spearman correlation analysis) statistics. Significance was set at 0.05 α level.
RESULTS/FINDINGS: The mean MFIS score was 31.74 ± 12.39. Many participants (58.7%) had moderate functional limitations due to fatigue. The result of Mann-Whitney U-test showed significant difference in functional limitation due to fatigue between participants with slight disability and those with moderate disability (p = 0.000), with participants with moderate disability having higher MFIS scores (more functional limitations). There was also a significant correlation between functional limitation due to fatigue and level of disability (ρ = 0.625, p = 0.000).
Functional limitation due to fatigue occurs frequently in stroke survivors and is related to level of disability. Functional limitations due to fatigue should be assessed frequently in all stroke survivors with varying degrees of disability and the outcome should be considered during rehabilitation and retraining of physical function.
中风幸存者的功能受限有时与疲劳相关。本研究评估了接受物理治疗的社区中风幸存者因疲劳导致的功能受限情况。确定了因疲劳导致的功能受限在性别、中风类型、患侧、年龄类别和残疾程度之间的差异。还确定了因疲劳导致的功能受限与这些变量之间的关系。
这是一项横断面研究，纳入了63名年龄在45至79岁之间（平均年龄为53.68±10.95岁）的中风幸存者（35名男性幸存者和28名女性幸存者）。使用改良疲劳影响量表（MFIS）评估因疲劳导致的功能受限情况。采用改良Rankin量表对参与者的残疾程度进行分类。数据采用描述性统计（均值、标准差、百分比和频率）和推断性统计（Mann-Whitney U检验和Spearman相关性分析）进行分析。显著性水平设定为0.05α。
结果/发现：MFIS平均得分为31.74±12.39。许多参与者（58.7%）因疲劳存在中度功能受限。Mann-Whitney U检验结果显示，轻度残疾参与者和中度残疾参与者因疲劳导致的功能受限存在显著差异（p = 0.000），中度残疾参与者的MFIS得分更高（功能受限更严重）。因疲劳导致的功能受限与残疾程度之间也存在显著相关性（ρ = 0.625，p = 0.000）。
中风幸存者中因疲劳导致的功能受限很常见，且与残疾程度相关。对于所有不同残疾程度的中风幸存者，都应经常评估因疲劳导致的功能受限情况，并且在身体功能康复和再训练过程中应考虑评估结果。
