Measurement of digital blood pressure before and after local cooling was performed in 10 men with traumatic vasospastic disease (TVD), 10 men who worked with vibrating tools but had no symptoms in arms or hands, and 10 men who had never worked with vibrating tools. The reduction in finger systolic pressure was significantly larger in the group with TVD than in either of the reference groups (p less than 0.001). There was no difference between the two reference groups. Nine of the 10 patients with TVD had a larger reduction in their finger systolic pressure after local cooling than anyone in either control group. The effects of two different room temperatures (17 degrees C and 23 degrees C) were evaluated. At the higher temperature the overlap between patients with TVD and controls was greater. The method described seems a feasible way to obtain an objective verification of TVD.
对10名患有创伤性血管痉挛疾病（TVD）的男性、10名使用振动工具但手臂或手部无症状的男性以及10名从未使用过振动工具的男性，在局部冷却前后测量了指血压。TVD组的手指收缩压降低幅度明显大于两个参照组中的任何一组（p<0.001）。两个参照组之间没有差异。10名TVD患者中有9名在局部冷却后手指收缩压的降低幅度大于任何一个对照组中的个体。评估了两种不同室温（17摄氏度和23摄氏度）的影响。在较高温度下，TVD患者与对照组之间的重叠更大。所描述的方法似乎是获得TVD客观验证的一种可行方法。
