Some preterm infants show a discrepancy in muscle power often recognisable as hyperextension of trunk and shoulders. Even if there is no evident pathology involved, the hyperextension influences later hand function. In this study we assessed a group of healthy infants (N=51) at the age of 39 weeks: 32 were born preterm (and corrected for gestational age) and 19 were born at term. Both quantitative and qualitative measures of hand function were obtained. It was found that the preterm infants scored significantly lower scores in both assessments for hand function. Moreover, a significant correlation was found between the quality of hand function at the age of 39 weeks and hyperextension of the trunk at 18 weeks. Hyperextension of the trunk at 18 weeks had a high predictive value for poor hand function at 39 weeks and thus should hold implications for clinical and therapeutic management.
一些早产儿表现出肌肉力量的差异，通常表现为躯干和肩部过度伸展。即使没有明显的病理因素，这种过度伸展也会影响后期的手部功能。在本研究中，我们评估了一组39周龄的健康婴儿（N = 51）：32名是早产儿（并根据胎龄进行了校正），19名是足月儿。我们获得了手部功能的定量和定性测量结果。结果发现，早产儿在两项手部功能评估中的得分均显著较低。此外，还发现39周龄时手部功能质量与18周时躯干过度伸展之间存在显著相关性。18周时躯干过度伸展对39周时手部功能不良具有较高的预测价值，因此对临床和治疗管理具有重要意义。
