Stress Analysis in AFO for Muscular and Gait Abnormalities Rehabilitation

Ankle–Foot Orthoses (AFOs) are helpful devices that support the people who are suffering with neuromuscular conditions or gait abnormalities. They are referred to as individuals with stroke or drop-foot, where impaired muscles limit safe and efficient walking. By balancing the ankle and guiding foot movement, AFOs play an important role in therapy and in rebuilding confidence during motion. Many old AFOs face challenges in discomfort, high stress at particular regions of the device, and limited products for different users.This case explains about mechanical properties and real time monitoring of AFOs. Using finite element analysis, we examine how stresses are distributed across the orthosis during walking, especially in demanding phases like heel-strike and toe-off. At the same time, we incorporate light weight electrical components— including pressure sensors and motion sensors — to monitor gait in real time. This twin strategy not only identifies areas where the orthosis can be redesigned for better strength and comfort, but also introduces the possibility of responsive, feedback-driven rehabilitation.The findings contribute toward the design of next-generation AFOs that are stronger, more comfortable, and smarter, helping patients with neuromuscular and gait impairments regain mobility and independence.
