A controlled study of the effects of pulsed ultrasound was carried out in conjunction with a standard treatment for healing chronic leg ulcers on 44 patients divided randomly into two groups. All patients received standard treatment (paste impregnated bandage and a self-adhesive elastic bandage) plus placebo-ultrasound or pulsed ultrasound (1:9, 0.5 watt/cm2 at 1 MHz, for 10 min) 3 days a week for 4 weeks, thereafter twice weekly for 4 weeks and once weekly for the following 4 weeks. Percentage healed ulcer area and comparison of percentage healed ulcers were examined after 4, 8 and 12 weeks. There were no significant differences in the proportion of healed ulcers or ulcer area in the pulsed ultrasound group as compared with the placebo group.
针对44名患者开展了一项关于脉冲超声效果的对照研究，这些患者被随机分为两组，研究结合治疗慢性腿部溃疡的标准疗法进行。所有患者均接受标准治疗（含药敷料绷带和自粘弹性绷带），外加安慰剂超声或脉冲超声（频率1兆赫，强度0.5瓦/平方厘米，每次10分钟，每周3次，持续4周，此后4周每周2次，接下来4周每周1次）。在4周、8周和12周后，检查溃疡愈合面积百分比以及愈合溃疡百分比的比较情况。与安慰剂组相比，脉冲超声组的溃疡愈合比例或溃疡面积均无显著差异。
