保持平衡是初学者的核心问题。为了研究婴儿如何科普由负重引起的额外平衡控制问题，14个月大的婴儿被负重15%的体重。对称和不对称的负载破坏交替步态模式，并导致不成熟的脚步模式。行走受到背部负荷的严重影响。行走经验少、行走熟练程度低和身体比例较胖的婴儿受到的不利影响更大。此外，婴儿表现出独特的姿势反应不对称的负载。与年龄较大的儿童和成年人相比，婴儿倾向于负载，而不是在负载的相反方向。研究结果进行了讨论，从住宿补偿策略的发展。
Maintaining balance is a central problem for new walkers. To examine how infants cope with the additional balance control problems induced by load carriage, 14-month-olds were loaded with 15% of their body weight in shoulder-packs. Both symmetrical and asymmetrical loads disrupted alternating gait patterns and caused less mature footfall patterns. Walking was most severely compromised by back loads. Infants with less walking experience, lower levels of walking proficiency, and chubbier body proportions were more adversely affected. In addition, infants displayed a unique postural response to asymmetrical loads. In contrast to older children and adults, infants leaned with loads rather than in the opposite direction to the loads. Findings are discussed in terms of development from accommodation to compensatory strategies.
