Wearable exoskeletons as catalysts for postoperative recovery and rehabilitation

Wearable robotic exoskeletons are emerging as pivotal tools in postoperative recovery, enabling early mobilization through powered joint assistance. This letter discusses their clinical and technological relevance in accelerating functional rehabilitation. Meta-analyses and clinical studies have demonstrated superior outcomes in joint motion, gait performance, and shorter hospital stays compared to conventional therapy. Devices such as Japan's HAL (Hybrid Assistive Limb) and Honda Walking Assist exemplify the fusion of biomechanics and AI-driven control, providing customizable torque support and real-time feedback. Implementation in Japan, Taiwan, the United States, and Europe underscores global recognition of their utility. Future research should focus on multicenter trials and ethical integration frameworks.
