Abstract

Pressure algometry can be used to quantify mechanical nociceptive threshold (MNT) in humans and animals. If reliable this may be a useful tool to examine calves for increased mechanical sensitivity, which may be induced by disease or pain. This study measures the repeatability and feasibility of pressure algometry using a handheld digital pressure algometer (PRODPlus, Top Cat metrology) using three serial measurements applied to six sites on the thoraces of 35 healthy calves by two different operators. The range of MNTs recorded in healthy calves was 1.2-25 Newtons (median = 10.1 IQR = 7.1-14.0). A multivariable mixed effects model identified that the MNT's recorded were influenced by Operator, Site, and Calf. Intra and inter-operator reliability were measured by intra-class correlation coefficients (ICCs). Based on average ICCs, intra-operator reliability at two sites was good; one site overlying the ventral aspect of the 6th intercostal space [ICC = 0.79 95% CI (0.63-0.89)] and the other overlying the dorsal aspect of the 9th intercostal space [ICC = 0.75 95% CI (0.56-0.87)]. Average ICCs for three other measurement sites were moderate or poor, and one site proved unfeasible. For inter-operator agreement average ICCs showed that agreement was also good at the same 6 and 9th intercostal space, [ICCs = 0.77 95% CI (0.35-0.90) and 0.77 95% CI (0.54-0.88), respectively], agreement was moderate for the remainder of the sites. This study identifies two sites that are potentially useful for monitoring of thoracic sensitivity as an indicator of pain in calves by means of pressure algometry using the average of three measurements. It also identifies sources of variability to be considered when applying the tool for clinical or research purposes.

摘要

压力痛觉测定法可用于量化人类和动物的机械性伤害感受阈值(MNT)。如果可靠的话,这可能是一种用于检查犊牛机械敏感性增加情况的有用工具,机械敏感性增加可能由疾病或疼痛引起。本研究使用手持式数字压力痛觉测定仪(PRODPlus,Top Cat计量公司),通过两名不同操作人员对35头健康犊牛胸部的六个部位进行三次连续测量,来测量压力痛觉测定法的可重复性和可行性。健康犊牛记录的MNT范围为1.2 - 25牛顿(中位数 = 10.1,四分位间距 = 7.1 - 14.0)。多变量混合效应模型确定,记录的MNT受操作人员、部位和犊牛的影响。通过组内相关系数(ICC)测量操作人员内和操作人员间的可靠性。基于平均ICC,两个部位的操作人员内可靠性良好;一个部位位于第6肋间间隙腹侧 [ICC = 0.79,95%置信区间(0.63 - 0.89)],另一个部位位于第9肋间间隙背侧 [ICC = 0.75,95%置信区间(0.56 - 0.87)]。其他三个测量部位的平均ICC为中等或较差,且有一个部位证明不可行。对于操作人员间的一致性,平均ICC表明在相同的第6和第9肋间间隙一致性也良好,[ICC分别为0.77,95%置信区间(0.35 - 0.90)和0.77,95%置信区间(0.54 - 0.88)],其余部位的一致性为中等。本研究确定了两个部位,通过使用三次测量的平均值,借助压力痛觉测定法监测犊牛胸部敏感性作为疼痛指标可能是有用的。它还确定了在将该工具用于临床或研究目的时需要考虑的变异性来源。
