Abnormal carpal configuration was observed in a litter of ten 2-month-old pups raised in a research colony. Five of the pups were exercised daily, and carpal configuration returned to normal within 7 to 10 days. The other 5 pups remained confined, and their carpal configuration returned to normal after 6 weeks. It was concluded that poor muscle tone was responsible for the carpal hyperextension.
在一个研究群体中饲养的一窝10只2月龄幼犬中观察到腕关节形态异常。其中5只幼犬每天进行锻炼，腕关节形态在7至10天内恢复正常。另外5只幼犬一直处于限制活动状态，它们的腕关节形态在6周后恢复正常。得出的结论是，肌张力低下是导致腕关节过度伸展的原因。
