Work-related upper extremity disorders (WRUEDs) are highly prevalent and costly. Development of fatigue is thought to be one of the causes of WRUEDs. Perceived fatigue can be assessed with the Borg CR Scale® (Borg CR10). The objective was to validate the Borg CR10 for the evaluation of shoulder perceived fatigue during lifting tasks. Seventy adults in working age performed three rhythmic lifting tasks with two loads (15% and 30% of maximal voluntary contraction). Using generalized repeated-measures ANOVA (Generalized Estimating Equations), statistically significant Task and Load effects (p < 0.001), as well as Task × Load interaction effects (p < 0.0001) were observed on Borg CR10, without any influence of sex. The Borg CR10 is a valid tool to assess shoulder perceived fatigue as it can discriminate between tasks of different difficulty levels in term of complexity, height, and resistance, regardless of sex.

与工作相关的上肢疾病 (WRUED) 非常普遍且昂贵。疲劳的发生被认为是 WRUED 的原因之一。感知疲劳可以使用 Borg CR Scale® (Borg CR10) 进行评估。目的是验证 Borg CR10 用于评估举重任务期间肩部感知疲劳。 70 名处于工作年龄的成年人执行了 3 项有节奏的举重任务，负载为两种负荷（最大自主收缩的 15% 和 30%）。使用广义重复测量方差分析（广义估计方程），在 Borg CR10 上观察到统计显着的任务和负载效应 (p < 0.001)，以及任务 × 负载交互效应 (p < 0.0001)，没有任何性别影响。 Borg CR10 是评估肩部感知疲劳的有效工具，因为它可以在复杂性、高度和阻力方面区分不同难度级别的任务，无论性别如何。
