Compared to the normal gait cycle, transtibial amputees have a 20% greater oxygen consumption. Fisher et al. in a study with non amputees using crutches found that their oxygen consumption reached 40% of the maximum and that their heart beat, 62% of maximum calculated for their age. Thus the authors concluded that the use of crutches in patients with heart pathologies should be considered with restraint. The metabolic output of ambulation with crutches is aproximately twice as much when compered to normal gait. The objective of this study is to compare the metabolic output of lower limb amputees when using crutches and prosthesis. This was done using the Shuttle Test and the K4b² â this is a fully portable pulmonary gas exchange system that allows us direct assess to the cardio-pulmonary limitations. Our study has shown that the metabolic output of ambulation with the prosthesis is less than that with crutches.
