Trigger points in painful muscle are a characteristic sign in patients with primary fibromyalgia. The MDO oxygen electrode was used to evaluate oxygenation in the subcutaneous tissue and in trigger points in the trapezius and brachioradial muscles. Ten patients and 8 normal controls were studied. The results in the patients were abnormal, with scattered or slalom-slope histograms, indicating low tissue oxygenation. The controls were normal, except in one case. The conclusion is that in patients with primary fibromyalgia, the muscle oxygenation is abnormal or low, at least in the trigger point area of the muscles.
疼痛肌肉中的触发点是原发性纤维肌痛患者的一个特征性体征。使用MDO氧电极评估斜方肌和肱桡肌皮下组织及触发点的氧合情况。研究了10例患者和8名正常对照者。患者的结果异常，直方图呈散在或曲折状，表明组织氧合较低。除1例对照者外，其余对照者结果正常。结论是，原发性纤维肌痛患者的肌肉氧合异常或较低，至少在肌肉的触发点区域如此。
