- 요약Millions of people worldwide experience mobility challenges that can adversely affect their health and quality of life. Lower-limb exoskeletons have the potential to enhance mobility by acting in parallel with the body to help people walk farther, faster, and with less fatigue. Designing effective assistance is challenging, however, given the complex interplay of individual and contextual factors that guide movement. Current exoskeleton systems are limited in their ability to accommodate changing behaviors over time and for varied individuals. This dissertation presents three studies that explore how interaction with ankle exoskeletons can be made more responsive to the multifactorial and dynamic nature of human gait.In the first study, we evaluate the effectiveness of a multi-objective approach to personalizing exoskeleton assistance for older adults. Optimizing ankle assistance for both energy economy and self-selected walking speed yielded meaningful improvements in both measures. We observed agerelated effects on responses to exoskeletons, including slower motor learning that may limit the effectiveness of existing training paradigms with aging populations.These results motivated the dissertation's subsequent studies to examine how people adapt to exoskeletons and how that adaptation process can be enhanced through training. We analyzed gait changes between novice and expert exoskeleton users and identified consistent trends associated with the acquisition of stable motor skill. While some benefits presented quickly, greater improvements corresponded with people mitigating initial perturbations caused by the exoskeletons. This finding provided new insight into the motor processes that support effective exoskeleton adaptation. Building on this work, we developed a biofeedback-based training approach to accelerate exoskeleton mastery. Guiding novice users to modify their gait kinematics to reduce initial exoskeleton-induced perturbations enabled them to benefit more from assistance in less time. These findings demonstrate the promise of personalized training approaches to enhance exoskeleton use.Together, the studies in this dissertation advance the design of adaptive exoskeleton systems that account for both human performance goals and learning dynamics. We demonstrated meaningful improvements in exoskeleton personalization and training, underscoring the importance of designing for human-exoskeleton interaction. Continued efforts in this area have the potential to make exoskeletons more effective, intuitive, and desirable, ultimately enabling these technologies to better support people with diverse mobility needs in real-world settings.
