The utilization of an overground robotic exoskeleton for gait training during inpatient rehabilitation—single-center retrospective findings

Abstract

Overground robotic exoskeleton gait training is increasingly utilized during inpatient rehabilitation yet without clear guidelines. We describe clinical characteristics associated with robotic exoskeleton gait training and examine outcomes of people with spinal cord injury and stroke who completed usual rehabilitation care with or without robotic exoskeleton gait training. Retrospective review of medical records over a 36 months period. Inpatients with spinal cord injury or stroke and ≥1 robotic exoskeleton gait training session were included. After obtaining a complete list of robotic exoskeleton gait training participants, medical records were reviewed for comparable matches as determined by gait functional independence measure score <4, age 18-100 years, meeting exoskeleton manufacturer eligibility criteria, and participating in usual care only. Functional independence measure was collected on all patients. For spinal cord injury, we collected the walking index for spinal cord injury II. For stroke, we collected the Stroke Rehabilitation Assessment of Movement Measure. Fifty-nine people with spinal cord injury (n = 31 robotic exoskeleton gait training; n = 28 usual care) and 96 people post-stroke (n = 44 robotic exoskeleton gait training; n = 52 usual care) comprised the medical record review. Fifty-eight percent of patients with spinal cord injury and 56% of patients post-stroke completed 5+ robotic exoskeleton gait training sessions and were included in analyses. Robotic exoskeleton gait training dosage varied between our patients with spinal cord injury and patients post-stroke. Robotic exoskeleton gait training utilization during inpatient rehabilitation required consideration of unique patient characteristics impacting functional outcomes. Application of robotic exoskeleton gait training across diagnoses may require different approaches during inpatient rehabilitation.
