Typically developing infants (n = 35) and infants with significant motor delay (n = 31) were assessed longitudinally over a year following early sitting readiness. The Gross Motor Function Measure (GMFM) Sitting Dimension was used to assess sitting capacity, and a 5-min free play observation was used to assess sitting performance.
Both capacity and performance increased at a faster rate initially, with more deceleration across time, in infants with typical development compared to infants with motor delay. At lower GMFM scores, changes in GMFM sitting were associated with larger changes in independent sitting for infants with typical development, and the association between GMFM sitting and independent sitting varied more across GMFM scores for typically developing infants.
Intervention and assessment for infants with motor delay should target both sitting capacity and sitting performance.
■通常发育中的婴儿(n=35)和具有明显运动延迟的婴儿(n=31)在早期坐好准备后的一年内进行纵向评估。粗大运动功能测量(GMFM)坐姿维度用于评估坐姿能力,并使用5分钟的自由玩耍观察来评估坐姿表现。
■容量和性能最初都以更快的速度增长,随着时间的推移,在具有典型发育的婴儿中,与具有运动延迟的婴儿相比。在较低的GMFM分数下,GMFM坐姿的变化与典型发育婴儿独立坐姿的较大变化相关,GMFM坐姿和独立坐姿之间的关联在一般发育婴儿的GMFM评分中差异更大。
■对运动延迟婴儿的干预和评估应同时针对坐姿和坐姿。
