We have studied changes in peripheral joint laxity occurring during pregnancy in 68 females using both the finger hyperextensometer to quantify laxity at the metacarpophalangeal joint of the index finger and Beighton et al.'s modification of the Carter and Wilkinson scoring system. Although the latter system recorded no change, the more sensitive hyperextensometer demonstrated a significant increase in joint laxity during the last trimester of pregnancy (0.02 greater than p greater than 0.01) over the readings from the same individuals after parturition. When primigravidae and multigravidae were compared, a highly significant increase in laxity was found in women having their second baby over those having their first (0.01 greater than p greater than 0.001), though no further increase in laxity occurred in subsequent pregnancies.
我们对68名女性孕期外周关节松弛度的变化进行了研究，使用手指过度伸展测量仪来量化食指掌指关节的松弛度，并采用Beighton等人对Carter和Wilkinson评分系统的改良方法。尽管后一种系统未记录到变化，但更灵敏的过度伸展测量仪显示，与产后同一人群的读数相比，妊娠晚期关节松弛度显著增加（0.02 > p > 0.01）。当比较初产妇和经产妇时，发现生第二胎的女性比生第一胎的女性松弛度显著增加（0.01 > p > 0.001），不过在随后的妊娠中松弛度没有进一步增加。
