There is limited data independently assessing the optimal use of the Cutometer MPA580. The purpose of this study is to test the hypothesis that the assessment of elastic recoil is significantly different when utilizing two different probe placement protocols. In protocol A, four trials were performed, in which the probe was removed from the skin between trials. In protocol B, the probe was not removed from the skin between trials. Fifty-four patients were enrolled and all completed the testing. When assessing elasticity (Ua/Uf), the inter-class correlation was 0.83 for protocol A and 0.48 for protocol B (p <0.001). There was no significant difference between individual trials for protocol A. Trial one of protocol B was significantly different (p < 0.001) than trials 2-4 for protocol B. Trial one of protocol B was not significantly different than any trial in protocol A. The results of this study suggest that the method in which a clinician performs repeated measure testing has a significant effect on the outcome measures when using the Cutometer. Removing the probe between trials appears to result in measures with higher reliability.
独立评估Cutometer MPA580最佳使用方法的数据有限。本研究的目的是检验以下假设：在使用两种不同的探头放置方案时，弹性回缩的评估存在显著差异。在方案A中，进行了四项试验，试验之间将探头从皮肤上取下。在方案B中，试验之间探头不从皮肤上取下。招募了54名患者，所有患者均完成了测试。在评估弹性（Ua/Uf）时，方案A的组内相关系数为0.83，方案B为0.48（p<0.001）。方案A的各个试验之间没有显著差异。方案B的试验1与方案B的试验2 - 4相比有显著差异（p<0.001）。方案B的试验1与方案A的任何试验相比没有显著差异。本研究结果表明，临床医生进行重复测量测试的方法在使用Cutometer时对结果测量有显著影响。试验之间取下探头似乎会使测量结果具有更高的可靠性。
