Robotic devices provide safe,intensive and task oriented rehabilitation to people with mild to severe neurologic injury.It does
1.precisely controllable assistance or resistance during movements
2.good repeatability
3.objective and quantifiable measures of subject performance,
4.increased training motivation through the use of interactive (bio)feedback.
In addition, this approach reduces the amount of physical assistance required to walk reducing health care costs [88,91] and provides kinematic and kinetic data in order to control and quantify the intensity of practice, measure changes and assess motor impairments with better sensitivity and reliability than standard clinical scales
