The muscle blood flow (MBF) in m. trapezius was studied in 7 subjects with fibromyotic pain syndrome before and during treatment with ultrasound (1 Watt/cm2) and during placebo treatment, using the local 133Xe-washout technique. MBF in the fibromyotic muscles was significantly reduced during ultrasound treatment (p less than 0.05) compared to the blood flow before the treatment and during placebo treatment 1.57 +/- SEM 0.52 and 2.51 +/- SEM 0.43 ml/100 g/min, respectively. In 6 normal trapezius muscles the mean MBF was 2.30 +/- SEM 0.44 ml/100 g/min before ultrasound treatment and 2.31 +/- SEM 0.41 ml/100 g/min during ultrasound therapy. MBF decreased in a lidocaine blocked fibromyotic muscle during ultrasound treatment while no effect on MBF was detectable during ultrasonic treatment a normal lidocaine pretreated muscle. It is concluded that ultrasound treatment decreases MBF in fibromyotic muscles and that this is paradoxical effect of ultrasound might be due to a direct effect on the vessels or a local release of vasoactive substances in the fibromyotic muscles.
采用局部¹³³Xe清除技术，对7例纤维肌痛综合征患者斜方肌的肌肉血流量（MBF）在超声治疗（1瓦/平方厘米）前、治疗期间以及安慰剂治疗期间进行了研究。与治疗前及安慰剂治疗期间相比，超声治疗期间纤维肌痛肌肉的MBF显著降低（p＜0.05），治疗前及安慰剂治疗期间的血流量分别为1.57±标准误0.52和2.51±标准误0.43毫升/100克/分钟。在6块正常斜方肌中，超声治疗前平均MBF为2.30±标准误0.44毫升/100克/分钟，超声治疗期间为2.31±标准误0.41毫升/100克/分钟。超声治疗期间，利多卡因阻滞的纤维肌痛肌肉的MBF降低，而在利多卡因预处理的正常肌肉进行超声治疗时，未检测到对MBF有影响。结论是，超声治疗可降低纤维肌痛肌肉的MBF，这种超声的矛盾效应可能是由于对血管的直接作用或纤维肌痛肌肉中血管活性物质的局部释放。
