This study aimed: (1) to evaluate the hand motor fatigability in people with spinal cord injury (SCI) and compare it with measurements obtained form an able-bodied population; (2) to compare the hand motor fatigability in people with tetraplegia and in people with paraplegia; and (3) to analyse if motor fatigability is different in people with SCI with and without clinical significant perceived fatigability.
96 participants with SCI (40 cervical and 56 thoracolumbar) and 63 able-bodied controls performed a simple hand isometric task to assess motor fatigability. The Fatigue Severity Scale was used for perceived fatigability evaluation.
The main results of this study can be summarized as follows: (1) the waning in muscle force (motor fatigability) during a fatiguing task is similar in controls and participants with SCI; (2) the motor fatigability is influenced by the maximal muscle force (measured at the beginning of the task); and (3) the perceived fatigability and the motor fatigability are largely independent in the individuals with SCI.
Our findings suggest that the capability to maintain a prolonged effort is preserved in SCI, and this capacity depends on the residual maximal muscle force in people with SCI.
本研究旨在：（1）评估脊髓损伤（SCI）患者的手部运动疲劳性，并与健全人群的测量结果进行比较；（2）比较四肢瘫痪患者和截瘫患者的手部运动疲劳性；以及（3）分析有无临床显著疲劳感的SCI患者的运动疲劳性是否存在差异。
96名SCI患者（40名颈髓损伤患者和56名胸腰段脊髓损伤患者）和63名健全对照者进行了一项简单的手部等长任务以评估运动疲劳性。使用疲劳严重程度量表评估疲劳感。
本研究的主要结果可总结如下：（1）在疲劳任务期间，对照组和SCI患者的肌肉力量减弱（运动疲劳性）相似；（2）运动疲劳性受最大肌肉力量（在任务开始时测量）的影响；（3）在SCI患者中，疲劳感和运动疲劳性在很大程度上是独立的。
我们的研究结果表明，SCI患者保持长时间努力的能力得以保留，并且这种能力取决于SCI患者残余的最大肌肉力量。
