The potential of lower limb exoskeletons to enhance life-space mobility and to leverage green exercise in the rehabilitation of older adults: an expert perspective

Purpose: As the global population aged 60+ grows, ensuring mobility and independence for older adults is a critical public health goal. This paper examines barriers to life-space mobility in older adults and explores wearable lower limb exoskeletons (LLEs) and green exercise as innovative solutions. Methods: Literature search and interdisciplinary expert input were utilized. Results: Life-space mobility, the physical space individuals move through daily, is often restricted by physical and environmental barriers, leading to increased dependency, depression, and reduced quality of life. LLEs offer promising support by compensating for decreased intrinsic capacities, thus facilitating outdoor mobility. Green exercise (i.e., physical activity in nature) provides mental and physical health benefits, further promoting mobility and well-being. Conclusion: Combining LLEs with green exercise may create powerful rehabilitation modalities, addressing both physical and mental aspects of aging. Integrating life-space mobility research into exoskeleton development and rehabilitation programs ensures these solutions meet real-world needs, supporting Healthy Aging by maintaining functional ability. Future research should focus on user-centered development of optimized exoskeleton designs for outdoor use, developing tailored rehabilitation programs, and educating healthcare professionals and caregivers to maximize benefits. This integrated approach holds potential to significantly improve life-space mobility and quality of life for the aging population.
