With the increasing number of people who have problems with their walking, a new type of gait rehabilitation training robot has been put forward and designed. In order to meet the requirements of the gait rehabilitation training, the whole mechanical structure and control system have been designed, and the model machine for gait rehabilitation training robot has been made. Using the human gait ...

objectives: the purpose of this study was to compare spatio-temporal gait parameters between elderly and young male subjects. methods & materials: 57 able-bodied elderly (72±5.5 years) and 57 healthy young (25±8.5 years) subjects participated in this study. a four segment model consist of trunk, hip, shank, and foot with 10 reflective markers were used to define lower limbs. kinematic data coll...

A spinal cord injury (SCI) disrupts the motor and sensory functions of the nervous system, limitingmotion capabilities and reducing the quality of life of affected people. An active stance-control knee-ankle-foot orthosis was developed and tested to aid incomplete SCI subjects by increasing theirmobility and independence [1]. A further improvement of the orthosis is conducted by...

This paper deals with the vertical and longitudinal control of a mechanical system which interacts intermittently with the environment. The control approach is based on Controlled LimitCycle for performing the hopping motion, whereas a nonlinear energy based control law is used for longitudinal motion control. The study of this simple system permits a better comprehension of more complicated le...

We present experimental data for an ankle exoskeleton that provides a metabolic benefit during running. Intuitively, there is an optimal level of power that any particular human can accept and use to benefit walking or running, which is a function of the particular human, the selected gait, and speed. We provide and discuss modeling optimization results to complement our recent data for the dev...
