一个改进的统计（加权Kappa）进行了测试，以审查的可靠性触诊踏板脉冲由三个观察员。训练后明显改善。在简化的常规顺序等级制度方面，可靠性也仍然存在。研究结果表明，当在描述脉冲时进行五种以上的区分或当数据完全减少到只有二分类（存在-不存在）系统时，可能会出现有用性或可靠性问题。
An improved statistic (weighted Kappa) was tested for reviewing the reliability of the palpation of pedal pulses by three observers. Significant improvement was noted after training. Reliability also persisted with respect to a reduced form of the conventional ordinal grading system. The findings indicated that problems of usefulness or reliability may arise when more than five distinctions are made in describing the pulses or when the data are completely reduced to only a dichotomous (present‐absent) system.
