Study Summary
To determine if below-knee amputees will walk with better efficiency wearing a CESR foot which stores energy at heel strike and releases energy releases energy during push-off.
Primary Outcome
VO2 was collected at rest and while walking at a controlled walking speed of 1.14 meters/second for 10 minutes until they reached a steady state for 3 minutes. This was repeated for each foot condition. VO2 at the steady state was recorded in ml/min and were subsequently converted to calories and and then to Watts. The data were then corrected for body weight by dividing by weight in Kg. The gross VO2 in Watts/Kg during walking were then adjusted to net VO2 in Watts/kg by subtracting the resting
Interventions
