Energy expenditure was measured using a metabolic measurement cart (MMC) for 8 patients with hip disarticulation (HD, group 1), 10 patients with hemipelvectomy (hp, group 2), and 11 able-bodied subjects (group 3). Velocity and O2 consumption of comfortable, fast, and slow walking speeds were measured with a MMC. Comfortable walking speeds with HD and hp were 51% to 61% of controls (p less than 0.001), but there was no difference in O2 uptake per minute among the three groups. Fast walking speeds for groups 1 and 2 was 70% to 75% of comfortable walking speeds in group 3 (p less than 0.01), and the mean O2 uptake of fast walking speeds in groups 1 and 2 was 40% to 50% more than that of group 3 at comfortable speeds. Energy cost per unit distance (work) was 80% to 125% greater with patient groups than with able-bodied subjects. The difference between the pre- and immediate postexercise pulse rates for comfortable walking speeds were higher in groups 1 and 2 than in group 3.
使用代谢测量推车（MMC）对8例髋关节离断患者（HD，第1组）、10例半侧骨盆切除术患者（hp，第2组）和11名健康受试者（第3组）进行能量消耗测量。使用MMC测量舒适、快速和慢速步行速度下的速度和耗氧量。HD组和hp组的舒适步行速度为对照组的51%至61%（p<0.001），但三组之间每分钟的耗氧量没有差异。第1组和第2组的快速步行速度为第3组舒适步行速度的70%至75%（p<0.01），第1组和第2组快速步行速度下的平均耗氧量比第3组舒适速度下的平均耗氧量高40%至50%。患者组每单位距离（功）的能量消耗比健康受试者高80%至125%。第1组和第2组舒适步行速度下运动前和运动后即刻脉搏率的差异高于第3组。
