Compliant gait assistance triggered by user intention.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference Jan 1, 2015
An automatic gait initialization strategy based on user intention sensing in the context of rehabilitation with a lower-limb wearable robot is proposed and evaluated. The proposed strategy involves monitoring the human-orthosis interaction torques an...

Double closed-loop cascade control for lower limb exoskeleton with elastic actuation.

Technology and health care : official journal of the European Society for Engineering and Medicine Jan 1, 2015
Unlike traditional rigid actuators, the significant features of Series Elastic Actuator (SEA) are stable torque control, lower output impedance, impact resistance and energy storage. Recently, SEA has been applied in many exoskeletons. In such applic...

Body weight support during robot-assisted walking: influence on the trunk and pelvis kinematics.

NeuroRehabilitation Jan 1, 2015
BACKGROUND: Efficacy studies concerning robot assisted gait rehabilitation showed limited clinical benefits. A changed kinematic pattern might be responsible for this. Little is known about the kinematics of the trunk and pelvis during robot assisted...
