Overview
Brief Summary
The main objective of this study is to quantitatively assess the robotic assistance given by an exoskeleton on patients gait parameters. Patients will be asked to walk with- and without the exoskeleton on a treadmill. During the study, the biomechanical and the energy consumption will be assessed.

Outcomes
Primary Outcomes
Energy cost (J.kg/m)
Time Frame: 1 week
A nasal mask is fitted to the subject to measure oxygen consumption (VO2) and carbon dioxide production (VCO2). The ratio between VCO2 and VO2 is used to calculate the respiratory exchange ratio (RER). The Joules of energy expended per liter of oxygen consumed were computed depending on the RER. RER is assessed in a standing and walking condition. Finally, the energy cost is obtained by the ratio "walking expended minus standing'' divided by speed.
Secondary Outcomes
- Temporo-spatial parameters of gait: step length(1 week)
- Temporo-spatial parameters of gait: stance phase(1 week)
- Temporo-spatial parameters of gait: cadence(1 week)
- Segmental kinematics of gait (°)(1 week)
- Muscle activation(1 week)
- Mechanical work (J.kg/m)(1 week)
