PurposeTo determine the relationship between physical methods of measuring lymphedema and self-reported swelling, their reliability, and standard error of measurement.MethodLymphedema in each arm of women with (n = 33) and without (n = 18) unilateral arm lymphedema, secondary to breast cancer was measured by self-report, bioimpedance spectroscopy (BIS), perometer, and the truncated cone method.ResultsThe physical measurement tools were highly reliable (ICC((2,1)): 0.94 to 1.00) with high concordance (r(c): 0.89 to 0.99). Self-report correlated moderately with physical measurements (r = 0.65 to 0.71) and was moderately reliable (ICC((2,1)): 0.70).ConclusionsLymphedema assessment methods are concordant and reliable but not interchangeable.
