Human gait requires both haptic and visual feedback to generate and control rhythmic movements, and navigate environmental obstacles. Current lower extremity wearable exoskeletons that restore gait to individuals with paraplegia due to spinal cord injury rely completely on visual feedback to generate limited pre-programmed gait variations, and generally provide little control by the user over the...
Patients affected by spinal cord injury cannot usually regain unassisted walking. This is why several research groups and companies have developed exoskeletons which enable these people to regain mobility in a standing position. The simplest joint configuration for exoskeletons is to actuate the knees and the hips in the sagittal plane. The ankles and feet are then unactuated and their range of motion...
This paper presents a gait-pattern adaptation algorithm for exoskeletons based on the Zero Moment Point criterion. The proposed exoskeleton is developed for lower limbs and based on a commercially available orthosis. The step length and duration are considered as the adaptation parameters, they are computed through minimization based on direct dynamics and considering the orthosis-patient interaction...
Normal gait needs both proprioceptive and visual feedback to the nervous system to effectively control the rhythmicity of motor movement. Current preprogrammed exoskeletons provide only visual feedback with no user control over the foot trajectory. We propose an intuitive controller where hand trajectories are mapped to control contralateral foot movement. Our study shows that proprioceptive feedback...
A mechatronic system for neurorehabilitation of motion system of the human lower limbs is presented. Moreover, the structure of the complex and its components — feet training device with acupressure effect on feet, half-bed standing frame (verticalizer), lower limbs exoskeleton to operate them in case of loss of mobility or for active workouts are presented. The complex is designed to help patients...
