Stroke often results in asymmetric gait due to reduced propulsive force in the affected leg, leading to mobility impairments and increased fall risk. This study focuses on the development and preliminary evaluation of a novel realtime multiple assistance system for asymmetric gait rehabilitation in stroke patients. Our system uses an instrumented treadmill equipped with force plates and provides real-time visual feedback and propulsion promotion. Propulsion promotion has two modes: propulsion-facilitating and propulsion-augmenting modes, which adjust treadmill belt speed to enhance the patient’s propulsive efforts. Two stroke patients participated in the preliminary evaluation, demonstrating increased propulsive force and impulse during training with real-time multiple assistance (i.e., visual feedback and propulsion promotion). The propulsion-facilitating mode resulted in a 16.67% increase in normalized maximum propulsive force and a 20.50% increase in propulsive impulse, while the propulsion-augmenting mode led to a 33.33% increase in normalized maximum propulsive force and a 24.59% increase in propulsive impulse. These results indicate that real-time multiple assistance, combining visual feedback and propulsion promotion, effectively enhances propulsive forces in stroke patients. The findings of this study underscore the potential of integrating advanced assistive mechanisms in gait rehabilitation, offering significant technical and clinical implications for enhancing propulsive force in stroke patients.
