Un-Tethered, Active Ankle-Foot Orthotic

Foot drop, or the inability to dorsiflex the foot (i.e., point your toe upward) is a fairly common lasting side-effect of a stroke, affecting approximately 20% of stroke survivors (∼1.3 million people each year). The customers have adopted the use of Ankle Foot Orthotics (AFOs) in order to aid in the dorsi-flexion of the foot. These passive devices do not allow users to safely move down inclines or stairs as the user’s foot will always be pointed upwards when off the ground.
