The use of mechanical ankle exercise devices with continuous passive motion (CPM) of the ankle joint can improve venous reflow in the lower limbs after operations. Duplex ultrasonography allows the observations of blood flow velocity and flow volume during continuous movement of the devices. We tested two different CPM devices for ankle movement in a preclinical study on 10 healthy, uninjured people and saw the following changes in the deep venous system in the common femoral vein: after 5 min of motion the velocity of the venous reflow was increased to 112.5% and the flow volume passing the femoral vein to 123% of the initial mean values. After 15 min of motion the devices led to an increase of the venous reflow velocity to 125% and of flow volume to 143% of the baseline values in the femoral vein. These positive effects were still evident even 15 min after the devices have been turned off.
使用具有踝关节连续被动运动（CPM）功能的机械踝关节锻炼设备可以改善术后下肢的静脉回流。双功超声检查能够在设备持续运动过程中观察血流速度和血流量。我们在一项针对10名健康未受伤人员的临床前研究中测试了两种不同的用于踝关节运动的CPM设备，并观察到股总静脉深静脉系统出现了以下变化：运动5分钟后，静脉回流速度增加到初始平均值的112.5%，通过股静脉的血流量增加到123%。运动15分钟后，这些设备使股静脉的静脉回流速度增加到基线值的125%，血流量增加到143%。即使在设备关闭15分钟后，这些积极效果仍然明显。
