PURPOSE
This study described developmental changes in treadmill (TM) stepping and physical activity (PA) of infants at risk for neuromotor delay (ND) and explored these changes by diagnosis of cerebral palsy (CP). Relationships of stepping and PA with walking onset were examined.
METHOD
Fifteen infants at risk for ND (9.9 +/- 2.4 months) were tested every 2 months on a TM until walking onset or 24 months of corrected age. We recorded PA profiles using an activity monitor. Throughout the study, 6 of the 15 infants received a CP diagnosis.
RESULTS
Infants increased alternating steps (AltStp), decreased toe contacts, and increased high-level PA. Infants with CP showed less AltStp, more toe contacts, and less high-level PA than those without CP. Infants' AltStp and high-level PA revealed a positive correlation to earlier onset of walking.
CONCLUSION
Future studies should examine whether a TM intervention could improve mobility in infants at risk for ND.
目的
本研究描述了有神经运动发育迟缓（ND）风险的婴儿在跑步机（TM）上的踏步和身体活动（PA）的发育变化，并通过脑性瘫痪（CP）诊断来探究这些变化。研究了踏步和PA与开始行走之间的关系。
方法
对15名有ND风险的婴儿（9.9±2.4个月）每2个月在跑步机上进行一次测试，直至开始行走或矫正年龄达到24个月。我们使用活动监测器记录PA情况。在整个研究过程中，15名婴儿中有6名被诊断为CP。
结果
婴儿交替踏步（AltStp）增加，足尖接触减少，高水平PA增加。与没有CP的婴儿相比，患有CP的婴儿AltStp更少，足尖接触更多，高水平PA更少。婴儿的AltStp和高水平PA与更早开始行走呈正相关。
结论
未来的研究应检验跑步机干预是否能改善有ND风险婴儿的运动能力。
