目的研究下肢深静脉血流的特点和穿戴式神经肌肉刺激器（geko; FirstKind Ltd）的作用，并探讨受试者对刺激器的耐受性。方法对10名健康志愿者进行开放性生理学研究。股浅静脉的双功超声检查测量了站立和仰卧位（下肢最初水平，然后抬高）的正常血流和横截面积。在激活放置在腓神经上的geko刺激器期间重复流量测量。在应用膝下石膏后重复该过程。参与者使用问卷（口头评分）和评分指数（视觉模拟量表）评估不适感。结果geko装置可显著增加有石膏模型（平均差异11.5 cm/sec-1; p = 0.001至0.13）和无石膏模型（平均差异7.7 cm/sec-1; p = 0.001至0.75）的下肢静脉血流量。当管型打开且geko不活动时，泊洛沙姆对静脉血流量峰值也有显著影响（p = 0.003至0.69），尽管这些差异不如geko的影响显著（平均差异3.1 cm/sec-1（-6.5至10））。geko设备的耐受性良好，参与者通常只报告使用该设备的轻微不适。结论geko装置可增加下肢静脉血流量，为石膏患者提供潜在的机械血栓预防。引用此文章：Bone Joint Res 2013;2：179-85。
Objectives We aimed to examine the characteristics of deep venous flow in the leg in a cast and the effects of a wearable neuromuscular stimulator (geko; FirstKind Ltd) and also to explore the participants’ tolerance of the stimulator. Methods This is an open-label physiological study on ten healthy volunteers. Duplex ultrasonography of the superficial femoral vein measured normal flow and cross-sectional area in the standing and supine positions (with the lower limb initially horizontal and then elevated). Flow measurements were repeated during activation of the geko stimulator placed over the peroneal nerve. The process was repeated after the application of a below-knee cast. Participants evaluated discomfort using a questionnaire (verbal rating score) and a scoring index (visual analogue scale). Results The geko device was effective in significantly increasing venous blood flow in the lower limb both with a plaster cast (mean difference 11.5 cm/sec-1; p = 0.001 to 0.13) and without a plaster cast (mean difference 7.7 cm/sec-1; p = 0.001 to 0.75). Posture also had a significant effect on peak venous blood flow when the cast was on and the geko inactive (p = 0.003 to 0.69), although these differences were less pronounced than the effect of the geko (mean difference 3.1 cm/sec-1 (-6.5 to 10)). The geko device was well tolerated, with participants generally reporting only mild discomfort using the device. Conclusion The geko device increases venous blood flow in the lower limb, offering a potential mechanical thromboprolylaxis for patients in a cast. Cite this article: Bone Joint Res 2013;2:179–85.
