The oxygen cost of walking by adults with an amputation has been well described, but few studies have focused on this parameter in children who had amputation. Children a transtibial reported to maintain speed at 15% higher than able-bodied children. purpose study was determine if the level differential impact self-selected and cost, how performance these compares that group children.Seventy-three participated study. Oxygen consumption measured Cosmed K4b2 analysis telemetry unit (Rome, Italy) as participants walked overground for ten minutes speed. One minute steady-state data were reduced, averaged, standardized control values. unilateral grouped according amputation; there twenty-nine Syme, thirteen transtibial, fourteen knee disarticulation, five transfemoral, hip disarticulation amputations. Seven bilateral amputation, they considered separate group. Comparisons made among groups between all undergone subjects. variables analyzed resting VO(2) rate (mL/kg/min), heart (beats per [bpm]), (mL/kg/m), (bpm), velocity (m/min).Unilateral transfemoral amputations resulted significantly reduced (80% 72% normal, respectively) increased (151% 161% respectively), while (124% normal). Compared controls, slower (87% normal), elevated (119% normal) similar energy cost. Syme or essentially same did normal age group.Children through distal able without increasing their Only when is above do walk
