Comparison Between the C-leg® Microprocessor-Controlled Prosthetic Knee and Non-Microprocessor Control Prosthetic Knees: A Preliminary Study of Energy Expenditure, Obstacle Course Performance, and Quality of Life Survey
This study investigated energy expenditure and obstacle course negotiation between the C-leg ® and various non-microprocessor control ( NMC ) prosthetic knees and compared a quality of life survey ( SF-36v2 ™ ) of use of the C-leg ® to national norms . Thirteen subjects with unilateral limb loss ( 12 with trans-femoral and one with a knee disarticulation amputation ) participated in the study . The mean age was 46 years , range 30 – 75 . Energy expenditure using both the NMC and C-leg ® prostheses was measured at self-selected typical and fast walking paces on a motorized treadmill . Subjects were also asked to walk through a st and ardized walking obstacle course carrying a 4.5 kg ( 10 lb ) basket and with h and s free . Finally , the SF-36v2 ™ was completed for subjects while using the C-leg ® . Statistically significant differences were found in oxygen consumption between prostheses at both typical and fast paces with the C-leg ® showing decreased values . Use of the C-leg ® result ed in a statistically significant decrease in the number of steps and time to complete the obstacle course . Scores on a quality of life index for subjects using the C-leg ® were above the mean for norms for limitation in the use of an arm or leg , equal to the mean for the general United States population for the physical component score and were above this mean for the mental component score . Based on oxygen consumption and obstacle course findings , the C-leg ® when compared to the NMC prostheses may provide increased functional mobility and ease of performance in the home and community environment . Question naire results suggest a minimal quality of life impairment when using a C-leg ® for this cohort of individuals with amputation
