The mechanical energy costs of walking were studied in 10 cerebral palsied children with hemiplegia to determine whether their values were substantially different from normal and, if so, to discover the movements that were responsible. A two-dimensional, sagittal-plane cinematographic analysis of the subjects' normal walking was undertaken. This technique provided continuous information about the mechanical energy costs of the whole body and each of its parts, the energy types involved, and the amounts of energy conserved. In most cases, the energy costs were above normal and were attributable to poor patterns of exchange between the potential and kinetic energy types of the head, arms, and trunk segment; to very low levels of kinetic energy that precluded exchange; or to both. We concluded that attention should be directed to restoring the sinusoidal pattern of motion and to the fluctuating speeds during each gait cycle when energy costs are a therapeutic consideration.
对10名偏瘫型脑瘫儿童的行走机械能消耗进行了研究，以确定其数值是否与正常情况有显著差异，若有差异，则找出造成这种差异的运动。对受试者的正常行走进行了二维矢状面电影摄影分析。该技术提供了有关全身及其各部位机械能消耗、所涉及的能量类型以及能量守恒量的连续信息。在大多数情况下，能量消耗高于正常水平，这归因于头部、手臂和躯干节段势能和动能类型之间不良的转换模式；动能水平极低，无法进行转换；或者两者皆有。我们得出结论，当考虑将能量消耗作为治疗因素时，应着重恢复运动的正弦模式以及每个步态周期中的速度波动。
