An outdoor dual-task study on cognitive-motor interference during exoskeleton-assisted walking

Frontiers in Psychology
IntroductionControlling a powered lower-limb exoskeleton may increase the demand for cognitive resources due to mechanical constraints and assisting torques that disrupt natural movement.MethodThis study employed a dual-task paradigm to investigate ...

A NOVEL CABLE-PULLEY UNDERACTUATED LOWER LIMB EXOSKELETON FOR HUMAN LOAD-CARRYING WALKING

, 2017
Wearable lower limb exoskeleton has comprehensive applications such as load-carrying augmentation, walking assistance, and rehabilitation training by using many active actuators in the joints to reduce the metabolic cost generally. The traditional fully

The spring stiffness profile within a passive, full-leg exoskeleton affects lower-limb joint mechanics while hopping

Royal Society Open Science
Passive, full-leg exoskeletons that act in parallel with the legs can reduce the metabolic power of bouncing gaits like hopping. However, the magnitude of metabolic power reduction depends on the spring stiffness profile of the exoskeleton and is ...

Gait pattern generator for control of a lower limb exoskeleton [PDF]

, 2018
The aim of the study was to propose a relatively simple central pattern generator (CPG) model, which can be used to control a lower limb exoskeleton. The mentioned generator and the simulation model of the human gait were developed based on experimental ...

A Distributed Pressure Sensor to Measure Human- Machine Interaction in Lower-Limb Exoskeletons

, 2014
—We present two generations of distributed pressure sensors used in human-machines interfaces of lower limb exoskeletons. These sensors are based on a mechano-optoelectronic transduction principle.
