The purpose of this study was to measure the relative energy expenditure through quantification of oxygen consumed in subjects wearing various advanced designs of lower limb orthoses and conventional braces. The designs developed at the Institute of Rehabilitation Medicine were compared with conventional braces and were found to result in a reduction of oxygen consumed from 9% to 16% depending on the type of orthosis. Portable Douglas bags were employed and the gas analyzed per unit distance-time with relation to volume of oxygen and carbon dioxide under steady state conditions. Savings in consumed oxygen are rather consistent with the advanced orthotic designs, even though the subjects varied with respect to age, weight, sex and disability. No data were taken without a device as the subjects under this circumstance frequently required an auxiliary aid, which would introduce another variable.
本研究的目的是通过量化穿戴各种先进设计的下肢矫形器和传统支具的受试者所消耗的氧气来测量相对能量消耗。将康复医学研究所开发的设计与传统支具进行比较，发现根据矫形器的类型，氧气消耗量可减少9%至16%。使用便携式道格拉斯袋，并在稳态条件下根据氧气和二氧化碳的体积按单位距离-时间分析气体。尽管受试者在年龄、体重、性别和残疾程度方面存在差异，但先进的矫形器设计在氧气消耗节省方面相当一致。在没有佩戴设备的情况下不采集数据，因为在这种情况下受试者经常需要辅助工具，这会引入另一个变量。
