Exoskeleton Rehabilitation for Complete Thoracic Spinal Cord Lesion: A Case Study

Background: Spinal cord injury is a life-changing condition for individuals who have previously been independent in activities of daily living. Motor recovery prognosis for individuals with complete spinal cord lesion above thoracic level ten is poor after nine months of injury. Although the corticospinal tract is responsible for voluntary mobility functions such as walking, it is possible, through neuroplasticity, that involuntary lower limb movements can be trained. Methods: This case study discusses the use of multi-modal rehabilitation strategies, from weightbearing exercises using traditional manual-controlled exoskeleton to ambulation using advanced automotive exoskeleton. Results: The patient’s perspective showed themes that align with the World Health Organization’s International Classification of Functioning and Disability. In spinal cord injury, majority of concerns are in environmental and personal factors. This could be due to the perceived permanent disability in complete spinal cord lesion. The moderate-intensity two-hour intervention using traditional and advanced exoskeletons during physical rehabilitation showed that it was possible to stimulate deep sensations, and muscle pull and cramp for a patient diagnosed with complete spinal cord lesion. Conclusions: The use of traditional and advanced exoskeletons in weightbearing exercises may benefit patients with complete spinal cord lesions in regaining deep sensations in the lower limbs.
