This study evaluated the effect of water temperature on hand volume during volumetric measurement using the water displacement method. Four volumetric measurements were taken for 24 normal subjects using four different water temperatures--5 degrees C (41 degrees F), 20 degrees C (68 degrees F), 35 degrees C (95 degrees F), and 45 degrees C (113 degrees F). Between volumetric measurements the skin temperature of the hand was allowed to return to baseline levels using an Orion biofeedback unit. In comparing the two extreme temperatures, the average change in hand volume was +5.8 milliliters (ml), which represented a deviation of 1.4% of the mean (coefficient of variation). In using a t-test to determine significance, it was found that the change in volume between these two temperatures was significant at the 0.01 level. In comparing the two moderate temperatures, the average change in hand volume was +1.9 ml, representing a deviation of 0.5% of the mean, with no statistical significance. For research purposes, this study suggests the need to control for water temperature when using a volumeter to measure hand edema. For general clinical practice, however, the use of "cool" or "tepid" water does not appear to alter hand volume readings significantly to be of concern.
本研究评估了在使用排水法进行容积测量时水温对手部容积的影响。对24名正常受试者使用四种不同水温——5摄氏度（41华氏度）、20摄氏度（68华氏度）、35摄氏度（95华氏度）和45摄氏度（113华氏度）进行了四次容积测量。在每次容积测量之间，使用奥立龙生物反馈装置使手部皮肤温度恢复到基线水平。比较两个极端温度时，手部容积的平均变化为+5.8毫升（ml），占平均值的1.4%偏差（变异系数）。使用t检验确定显著性时发现，这两个温度之间的容积变化在0.01水平上具有显著性。比较两个适中温度时，手部容积的平均变化为+1.9 ml，占平均值的0.5%偏差，无统计学显著性。出于研究目的，本研究表明在使用容积计测量手部水肿时需要控制水温。然而，对于一般临床实践，使用“冷水”或“温水”似乎不会对手部容积读数产生显著影响而值得关注。
