使用代谢测量车（MMC）测量8例髋关节离断术患者（HD，第1组）、10例半骨盆切除术患者（hp，第2组）和11例身体健全受试者（第3组）的能量消耗。用MMC测量舒适、快速和慢速步行速度的速度和O2消耗。HD和hp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O2摄取量无差异。第1组和第2组的快速步行速度是第3组舒适步行速度的70%至75%（p <0.01），第1组和第2组快速步行速度的平均O2摄取量比第3组舒适速度的平均O2摄取量高40%至50%。患者组每单位距离（功）的能量成本比健全受试者高80%至125%。第1组和第2组的舒适步行速度运动前和运动后即刻脉率之间的差异高于第3组。
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.
