Figure 1From: Using an electrohydraulic ankle foot orthosis to study modifications in feedforward control during locomotor adaptation to force fields applied in stanceSchematic view of the ElectroHydraulic ankle foot Orthosis (EHO). Left. Line drawing of the drive system with an electric motor as the mechanical actuator. Right. Picture of the ankle foot orthosis. These two systems are connected by pneumatic cylinders and hoses filled with water instead of air to minimize compressibility effects.Back to article page
