Investigating Auto Adjusting Dynamic AFO

Conditions: Lower Limb; Fusion, Congenital, Lower Limb Fracture, Ankle Foot Injury

Sex: All

Ages: 18 Years – N/A

Healthy volunteers: Yes

Phase: NA

Enrollment: 22

Sponsor: University of Washington

Location: University of Washington, Dept. of Bioengineering Seattle Washington

Summary

Offloading Ankle Foot Orthoses (AFOs) are devices designed for people following lower-limb reconstruction to restore mobility by reducing mechanical loading through the injury site and redistributing it proximally. While they perform well for some users, their current form limits full functional potential and may put joints proximal to the injury at risk of long-term damage. This study is directed toward designing and testing a lightweight, variable stiffness, dynamic brace that can adjust in response to user activity.
