title: Muscular activity when walking in a non-anthropomorphic wearable robot.
abstract: Wearable robots should be designed not to alter human physiological motion. Perturbations introduced by a robot can be quantified by measuring EMG activity. This paper presents tests on the LENAR, an intrinsically back-drivable non-anthropomorphic lower limb wearable robot designed to provide hip and knee flexion/extension assistance. In previous works the robot was demonstrated to exhibit low mechanical impedance and to introduce minor alterations to human kinematic patterns during walking. In this paper muscular activity is assessed, demonstrating small alterations in the EMG patterns during the interaction with the robot, in both unpowered and assistive mode.
