Project Overview

Children with spastic diplegia cerebral palsy commonly have a crouched stance and gait due to a forward shift of the center of mass coupled with shortened, taut, weak muscles and muscle spasticity. Currently commercially available braces and ankle foot orthotics used to improve crouch gait are either rigid at the ankle or articulated to allow dorsiflexion and plantarflexion of the ankle. Rigid braces inhibit the development of a more normal walking gait, and articulated braces often allow for excessive flexion, especially during high stress or fatigue. The proposed brace design will include variable resistance to dorsi/plantar flexion to allow for high stability in times of fatigue and less resistance during therapeutic gait training, providing eccentric muscle strengthening and more normal gait kinematics throughout the lower limb. This is a continued project from Fall 2014 where the prototype was built but some aspects of the design need to be more ergonomic and user friendly for the patient. Goals for this semester are to complete the IRB so that we can begin testing of the device on our patient, possible kit assembly, and publication for May 2016.
