A comparative evaluation of oxygen consumption and gait pattern in amputees using Intelligent Prostheses and conventionally damped knee swing-phase control
Objective : To compare the gait of amputees wearing conventionally damped pneumatic swing-phase control knees and  microchip-controlled Intelligent Prostheses .  Design : Crossover trial . Setting : An amputee rehabilitation centre in a teaching hospital . Participants : Ten established unilateral transfemoral prosthetic users were asked to participate in the trial ; all agreed . Interventions : The amputees were assessed wearing pneumatic swing-phase control knees and then with the Intelligent Prosthesis . Main outcome measures : Oxygen consumption while walking at different speeds on a treadmill , video-recording of gait assessed by a panel and temporal – spatial parameters of gait whilst walking at slow , fast or normal speeds in a gait laboratory . Results : Mean oxygen cost for all subjects at 0.69 m/s was 0.33 ml/kg.m with the conventional limb and 0.30 ml/kg.m with the Intelligent Prosthesis ( p–0.01 ) . At 1.25 m/s the mean oxygen cost for the conventional limb was 0.24 ml/kg.m and for the Intelligent Prosthesis was 0.22 ml/kg.m ( not significant ) . The ANOVA analysis showed that oxygen cost was similar at normal walking speeds but increased more at lower speeds for the pneumatic swing-phase control leg compared to the Intelligent Prosthesis ( p<0.02 ) . There were no significant differences in subjective gait evaluation or temporal and spatial gait parameters . Conclusion : At lower speeds oxygen cost was lower with the Intelligent Prosthesis . Gait analysis detected no significant changes between the two legs
