Abstract: Orthosis device and related methods for controlling the device to counteract a gravitational force exerted on the person without directing the orthosis device in a pre-determined pattern of motion.

Abstract: The present disclosure is relates to an orthosis device. The orthosis device, in one embodiment, includes an actuator housing, and an electric motor coupled to the actuator housing, the electric motor including a motor stator and a motor rotor, and the electric motor further having high output torque. The orthosis device, in this embodiment, further includes a low-ratio transmission coupled to the actuator housing, the transmission including a gear system coupled to the actuator housing, and a drive system coupling the electric motor and the gear system, wherein a combination of the electric motor and transmission provide a user backdrivable orthosis device.
