Challenge-Based Adaptation of Exoskeleton Assistance and Gamified Biofeedback Enables Automated Gait Rehabilitation.

Robotic and biofeedback-assisted interventions are promising alternatives to surgical intervention and supplements for traditional physical therapy for children with gait impairments. This work utilizes a human-in-the-loop optimization strategy to adaptively modulate parameters for a lightweight robotic knee exoskeleton and biofeedback video game to maximize learning potential following the challenge point framework. We tested our approach on three able-bodied participants and one pediatric patient with genu recurvatum, a common walking pattern in children with neurological injuries.
