Shoulder muscle performance was tested in 8 working ankylosing spondylitis (AS) patients and compared with 10 healthy male referents. The AS patients were all in a non-active state and had no shoulder symptoms. Electromyographic fatigue development in the descending part of the trapezius muscle was significantly faster in the AS group during an endurance time test than in the referents. This indicates a change in muscle function consistent with previous reports of myopathy in AS patients. There were no significant differences in shoulder forward flexion strength, endurance time or recovery of endurance time between the AS patients and the referents.
对8名处于工作状态的强直性脊柱炎（AS）患者的肩部肌肉功能进行了测试，并与10名健康男性对照者进行比较。这些AS患者均处于非活动状态且无肩部症状。在耐力时间测试中，AS组斜方肌下降部分的肌电图疲劳发展明显快于对照者。这表明肌肉功能发生了变化，与之前关于AS患者肌病的报道一致。AS患者与对照者在肩部前屈力量、耐力时间或耐力时间恢复方面无显著差异。
