我们比较了三名年龄在51岁至55岁之间的患者在使用机械控制站立相位控制膝关节（Otto Bock 3R 15）和微处理器控制气动摆动相位控制膝关节（智能假体，IP）时单侧髋关节离断的行走过程中的能量消耗。所有患者均使用内骨骼髋关节离断假体，Otto Bock 7 E7髋关节和单轴足。以30、50和70 m/min的速度行走时测量能量消耗。2名患者显示，在相同速度下，与Otto Bock 31315相比，使用IP时的摄氧量（单位时间能量消耗，ml/kg/min）降低了10.3%至39.6%。在30 m/min时氧摄取量没有显示出任何显著差异，但在50和70 m/min时，使用IP时发现摄取量降低10.5%至11.6%。IP的使用降低了这些患者行走的能量消耗。
We have compared the energy expenditure during walking in three patients, aged between 51 and 55 years, with unilateral disarticulation of the hip when using the mechanical-controlled stance-phase control knee (Otto Bock 3R15) and the microprocessor-control led pneumatic swing-phase control knee (Intelligent Prosthesis, IP). All had an endoskeletal hip disarticulation prosthesis with an Otto Bock 7E7 hip and a single-axis foot. The energy expenditure was measured when walking at speeds of 30, 50, and 70 m/min.Two patients showed a decreased uptake of oxygen (energy expenditure per unit time, ml/kg/min) of between 10.3% and 39.6% when using the IP compared with the Otto Bock 31315 at the same speeds. One did not show any significant difference in the uptake of oxygen at 30 m/min, but at 50 and 70 m/min, a decrease in uptake of between 10.5% and 11.6% was found when using the IP. The use of the IP decreased the energy expenditure of walking in these patients.
