Abstract：The ankle-foot orthosis(AFO)achieves ankle joint movement control through mechanical support and biomechanical design,and is widely used in the rehabilitation of neurological muscle and orthopedic diseases.In recent years,the advancements in sensors,control strategies,data-driven technologies and additive manufacturing have provided support for the functionalization and lightweight design of AFO.This article systematically reviews the research progress of AFO in aspects such as sensors,control strate-gies,driving technologies,as well as manufacturing material innovations,and analyzes the application scenarios including neurological rehabilitation,orthopedic rehabilitation and elderly assistive walking.Finally,the application prospects of AFO technology in motion in-tention recognition and prediction,deep learning-driven personalized intervention and multi-driver efficiency optimization are outlined to provide a reference basis for the miniaturization,personalization and multi-scenario application of AFO.
