In 60 right-handed women, significant asymmetry of arm volume has been found, the right arm being, on average, the larger by 1.6 per cent. In 26 ambidextrous and 19 left-handed women the right arm was smaller than the left one by 0.1 and 1.4 per cent respectively. These values differed from zero at low levels of significance. In an early stage of oedema for correcting the error incurred in the estimation of arm volume by asymmetry the regression equation of the form VC = kVM + m is proposed where VC and VM are the volumes of the calculated--oedematous arm in its pre-oedematous state and the unaffected arm, respectively, k and m are constants, which were determined from measurements on samples of the righthanded, ambidextrous and left-handed women. A simplified equation of the form VR = VL + mo where VR and VL are the volumes of the right and left arms, respectively is proposed.
在60名惯用右手的女性中，发现手臂体积存在显著不对称，右臂平均比左臂大1.6%。在26名双手灵巧和19名惯用左手的女性中，右臂分别比左臂小0.1%和1.4%。这些数值在低显著性水平下与零有差异。在水肿早期，为校正因不对称而在手臂体积估计中产生的误差，提出了形式为VC = kVM + m的回归方程，其中VC和VM分别是计算得出的处于水肿前状态的水肿手臂和未受影响手臂的体积，k和m是常数，它们是通过对惯用右手、双手灵巧和惯用左手女性样本的测量确定的。还提出了形式为VR = VL + mo的简化方程，其中VR和VL分别是右臂和左臂的体积。
