许多早产儿可能会经历所谓的轻微发育障碍;然而，一般来说，运动行为的问题直到学龄才被发现。为了引入旨在预防这些问题的治疗方法，我们需要增加对早期运动功能和功能障碍的了解。本研究的重点是组织达到运动的足月和早产儿无脑瘫。对63例早产儿在校正后4个月和6个月时的伸手行为进行纵向评估。在6月龄和12月龄时进行临床评估。根据新生儿早期在新生儿重症监护室的发病率，将早产儿分为高风险组和低风险组。纳入了之前在足月婴儿（n = 13）中进行的研究结果。测量仰卧位伸展运动的运动学参数，分析运动速度和运动单位。运动学变量的复合参数被创建，反映了到达运动的质量。目前的研究表明，在4个月大时，低风险早产儿比足月和早产高风险婴儿表现出更多的最佳伸手行为。这种更好的接触表现与生命第一年期间更好的一般运动和行为发展有关。6月龄时，低风险组在伸手行为方面的优势消失，而高风险组出现了非最佳伸手行为形式的劣势。
Many preterm infants may experience so-called minor developmental disorders; however, in general, the problems in motor behavior are not detected until school age. To introduce therapies aimed at the prevention of these problems, we need to increase our knowledge of motor function and dysfunction at early age. The present study focused on the organization of reaching movements in full-term and preterm infants without cerebral palsy. The reaching behavior of premature infants (n = 63) was assessed longitudinally at the corrected ages of 4 and 6 mo. Clinical assessments were made at 6 and 12 mo of age. On the basis of the infant's morbidity during the early stay in the neonatal intensive care unit, the preterm infants were allocated into a high-risk and a low-risk group. Results from a previous study in full-term infants (n = 13) were included. Kinematics of reaching movements in supine position were measured, and the analysis focused on movement velocity and movement units. A compound parameter of kinematic variables was created, reflecting the quality of reaching movements. The present study showed that at the age of 4 mo, low-risk preterm infants showed more often optimal reaching behavior than full-term and preterm high-risk infants. This better reaching performance was related to a better general motor and behavioral development during the first year of life. At the age of 6 mo, the advantage of the low-risk group in reaching behavior had disappeared and a disadvantage in the form of nonoptimal reaching behavior of the high-risk group emerged.
