It also attempted to indicate the specific feature responsible for a controlled gait with optimum energy cost for BK amputees. Selection criteria of the subjects were similar physical parameters and quality of life studied with WHOQOL-100 quality of life assessment. A Cosmed? k4 b2 Respiratory Analyzer system was used for the measurement of Oxygen Uptake (VO2), Energy Expenditure per minute (EE) and Heart Rate (HR). Gait efficiency (p < 0.0002) was found higher for BK amputee than normal subject. The therapeutic activities and mainly walking rhythm contributed to improve the mobility & balance. This ensures the optimum time & co-ordination of movements and hence improves the gait efficiency for the BK amputee. Comparison with control group was performed to validate the data. %N 3 %K Energy Cost; Gait Efficiency; Below knee amputee %E Dr. Srinivas Kakkilaya %V 9 %D 2010 %I Dr. B.S. Kakkilaya %L cogprints7117
