A Method to Measure the Accuracy of Loads in Knee-Ankle-Foot Orthoses Using Conventional Gait Analysis, Applied to Persons With Poliomyelitis

A practical method that directly measures moments and forces in conventional KAFOs has been applied to show that conventional gait analysis techniques substantially underestimate knee joint moments in the KAFOs of persons with poliomyelitis. Underestimation of orthotic loads could result in underdesigned orthotic components and ultimately higher incidence of component failure in clinical applications.
