Prospective, Open label, single arm, non-randomized, non-comparative registry study of Robot-Assisted Physiotherapy Exercises with the REX Robot powered exercise system in patients with Spinal cord or other injury preventing unsupported patient ambulation.

The objective of this feasibility study is to evaluate the overall device safety when used in Spinal Cord Injury Hospitals or Rehabilitation Centers under the supervision of a physician and/or qualified rehabilitation specialists.
