目的：这项研究是为了确定一个商业的指针加（点探测器）在检测一个地区的低皮肤电阻的耳朵设计的特异性和灵敏度：这是一个前瞻性的盲研究设置/位置：该研究是在耶鲁纽黑文医院，纽黑文，CT主题：主题是男性和女性谁在耶鲁纽黑文医院工作干预措施：没有干预措施结果措施：相关性之间的自我报告的肌肉骨骼疼痛和检测低皮肤电阻的耳朵结果：阳性预测值为指针加检测低皮肤电阻与法国耳廓地图的颈部区域是0.76（76%）。Pointer Plus检测与French耳标测图的下背部区域相关的低皮肤电阻区域的阳性预测值为0.25。Pointer Plus检测有两次以上肌肉骨骼疼痛的患者外耳皮肤电阻降低的阳性预测值为0.29。结论：市售的Pointer Plus（探点器）检测外耳皮肤电阻降低区域的特异性和敏感性不可靠，取决于基于已发表的耳廓图的相关区域。需要额外的评估来支持临床实践。
Objectives:This study was done to determine the specificity and sensitivity of a commercial Pointer Plus (Point finder) in detecting a region of low skin resistance on the ear.Design:This was a prospective blinded study.Setting/location:The study was done at the Yale New Haven Hospital, New Haven, CT.Subjects:The subjects were men and women who work at Yale New Haven Hospital.Interventions:There were no interventions.Outcome measures:Correlations were made between self-reported musculoskeletal pain and the detection of low skin resistance on the ear.Results:The positive predictive value for Pointer Plus detecting low skin resistance correlating to the neck region of French auricular map is 0.76 (76%). The positive predictive value for Pointer Plus to detect low skin resistance area correlating to the low back region of French auricular map is 0.25. The positive predictive value for Pointer Plus in detecting any low in skin resistance on the external auricles in patients who complained of more than two musculoskeletal pains is 0.29.Conclusions:The specificity and sensitivity of a commercial Pointer Plus (point finder) in detecting a region of low skin resistance on the ear being unreliable, depending on the correlating area based on a published auricular map. Additional assessments are needed to support the clinical practice.
