Apparatus comprising a support system for a user and its operation in a gravity-assist mode

The present application relates to devices and systems for rehabilitation of the locomotor system, for example limbs. In particular, the present application discloses an apparatus, more in particular a robotic platform capable of optimizing gravity-dependent trunk movements, enabling overground locomotion in non-ambulatory individuals with spinal cord injury and stroke, while promoting durable motor improvement when delivered during gait rehabilitation facilitated by electrical spinal cord stimulation.
