Arm lymphedema is routinely assessed by clinicians and researchers, using arm circumference measurements. A protocol was developed for measuring arm circumference independent of medically trained professionals. The aim of this project was to assess the protocol's inter-rater reliability and its coherence with perometry measures.
Community-dwelling adults (n = 57), aged 60.2 ± 12.8 years, in good general health, were included in this study. Circumference of both arms were measured at the ulnar styloid of the wrist and at four 10 cm intervals up the arm by a friend of the participant, as well as the trained assessor using a tape measure. The same measures were also obtained with a perometer. The assessment tools had moderate to high concordance (r(c) = 0.84-0.94 for assessor vs. perometer and r(c) = 0.68-0.93 for assessor vs. participant). Limits of agreement analysis revealed that the mean difference between methods varied based on the measurement location; the bias ranged from -5.5% to 1.5% for assessor-measured vs. perometer methods and from -2.4% to 4.0% for assessor-measured vs. participant-measured methods.
The written instructions and cartoons are reliable tools that could be used by women at risk of lymphedema as well as those with lymphedema following treatment for breast cancer to measure their arm circumference reliably independent of medically trained personnel.
临床医生和研究人员通常通过测量手臂周长来评估手臂淋巴水肿。已制定了一项无需医学专业人员参与即可测量手臂周长的方案。本项目的目的是评估该方案的评分者间信度及其与周径测量法测量结果的一致性。
本研究纳入了57名社区居住的成年人，年龄为60.2±12.8岁，总体健康状况良好。由参与者的一位朋友以及经过培训的评估人员使用卷尺在手腕尺骨茎突处以及沿手臂向上每隔10厘米处测量双臂周长。同时也使用周径测量仪进行相同的测量。评估工具具有中度到高度的一致性（评估人员与周径测量仪之间的r(c)=0.84 - 0.94，评估人员与参与者之间的r(c)=0.68 - 0.93）。一致性界限分析表明，不同测量位置的方法间平均差异有所不同；评估人员测量法与周径测量仪测量法之间的偏差范围为 - 5.5%至1.5%，评估人员测量法与参与者测量法之间的偏差范围为 - 2.4%至4.0%。
书面说明和示意图是可靠的工具，有淋巴水肿风险的女性以及乳腺癌治疗后患有淋巴水肿的女性可使用这些工具，无需医学专业人员即可可靠地测量手臂周长。
