For assessment of cardiovascular effects of sensorimotor work, blood pressure is commonly measured by arm sphygmomanometry. A technique introduced by Penaz makes it feasible to monitor blood pressure noninvasively and continuously from the finger artery which measures give high correlations with intraarterial measurement. This study compared blood-pressure changes induced by a standard sensorimotor task using sphygmomanometry and the Penaz-method. It was investigated whether sphygmomanometrically recorded blood pressure can be used to estimate task-induced blood-pressure changes and whether inflating the cuff to different maximum pressures induces blood-pressure changes. 46 normotensive individuals were randomly assigned to the discomfort group (maximum arm-cuff pressure of 280 mmHg) or to the control group (maximum arm-cuff pressure of 160 mmHg). The experiment consisted of six tasks of 4 min. each. Results indicated that sphygmomanometries under-estimated task-induced blood-pressure changes and that phasic systolic and diastolic blood-pressure elevations during the task were leveled off shortly after the end of the task. Effects of 'cuff-inflation hypertension' were not found. The Penaz-method appears to be more appropriate than sphygmomanometry if dynamic aspects of blood pressure are of interest.
为评估感觉运动工作对心血管的影响，通常采用手臂血压计测量血压。佩纳兹引入的一项技术使得从手指动脉无创且连续地监测血压成为可能，所测数据与动脉内测量结果高度相关。本研究比较了使用血压计和佩纳兹方法由标准感觉运动任务引起的血压变化。研究探讨了通过血压计记录的血压是否可用于估计任务诱发的血压变化，以及将袖带充气至不同的最大压力是否会引起血压变化。46名血压正常的个体被随机分为不适组（手臂袖带最大压力为280毫米汞柱）或对照组（手臂袖带最大压力为160毫米汞柱）。实验由六个时长为4分钟的任务组成。结果表明，血压计低估了任务诱发的血压变化，并且任务期间的阶段性收缩压和舒张压升高在任务结束后不久就趋于平稳。未发现“袖带充气性高血压”的影响。如果关注血压的动态变化，佩纳兹方法似乎比血压计更合适。
