A Trial on the Clinical and Socioeconomic Impact of Wearable Exoskeletons for Spinal Cord Injury Rehabilitation in the Spanish Healthcare System

Inclusion Criteria: * diagnosis of spinal cord injury (SCI) in the acute or subacute phase (\< 6 months of evolution) * traumatic or non-traumatic aetiology * neurological level of the SCI between C5 and L5 for patients with American Spinal Injury Association Impairment Scale (AIS) C or D, and SCI between C7 and L5 for patients with AIS A or B. * sufficient strength in the upper extremities to handle a walker (triceps muscle score ≥ 4 according to the Medical Research Council (MRC) scale). * range of motion (ROM) without limitations in the lower extremities (achieve at least a knee extension of 10 degrees and neutral ankle position) * muscle spasticity in the lower extremities with a score ≤ 3 on the Modified Ashworth Scale (MAS) * tolerate bipedalism (having stood up in the last year) * aged between 18 and 70 years, with height between 150 cm and 190 cm, and weight less than 100 kg Exclusion Criteria: * WISCI ≥ 15 * cognitive or neurological limitations that prevent following instructions * another neurologic disorder permanently affecting gait and gait therapy (other than SCI) * grade I or higher in the European Pressure Ulcer Advisory Panel (EPUAP) in the areas of contact with the exoskeleton * unresolved fractures at the time of the study * uncontrolled autonomic dysautonomia * intolerance to exercise * uncontrolled epilepsy * previous experience with Robotic-Assisted Gait Training (RAGT). * ROM restriction such as flexing or arthrodesis will be excluded * spinal instability (or spinal orthotics unless cleared by a medical doctor). * deterioration \>3 points of the total in the motor score of the International Standards for the Neurological Classification of Spinal Cord Injury (ISNCSCI) in the last 4 weeks. Loss of sensation and/or motor activity above the level of injury detected that has not been evaluated by a doctor.
