Brief Summary:
Spinal Cord Injury (SCI), being a devastating diagnosis, has little to no recovery which leads to a long-standing of debilitating impairment for affected patients. The National Neuroscience Institute (NNI) Neurosurgery team, together with our collaborators, will be embarking on a new clinical pilot trial named RESTORES: RESToration of Rehabilitative function with Epidural Spinal Stimulation. This study aims to investigate the feasibility of electrical stimulation via a spinal cord stimulator (SCS), which will be implanted into the study subjects, and advanced robotic neuro-rehabilitation to aid in improving neurological function in patients diagnosed with chronic SCI. A total of 3 patients, male and female participants, above the age of 21 who have been diagnosed with the condition for more than a year will be recruited for this study over a 2-year period. Rehab sessions will take place pre and post-surgical implant, assessing subject improvements.

Condition or disease Intervention/treatment Phase
Chronic Spinal Cord Injury Device: RESToration Of Rehabilitative function with Epidural spinal Stimulation Not Applicable

Detailed Description:
Motor complete SCI is defined as American Spinal Injury Association (ASIA) impairment Grade A or B, with no motor function preserved below the level of injury. This in-turn results in significant catastrophic dysfunction and disability to the individual's physical and mental health, reducing quality of life and increasing caregiver burden which translates to high socioeconomic costs. The current treatments for chronic SCI involves aggressive rehabilitation to maximize residual neurological function and devices to compensate for neurological loss. However, neurological improvement is dismal, with 94.4% of patients demonstrating no neurological improvement 5-years post-injury. Experimental and electrophysiological observations revealed that spinal networks have the capacity to generate basic locomotor rhythmicity without supraspinal input to the cord. SCS, consisting of a small array of electrodes surgically implanted into the spinal epidural space stimulates afferent sensory pathways in specific patterns to drive voluntary and autonomically controlled motor responses. Activity-based training in conjunction with SCS has been shown to bolster neuroplasticity and recovery caudal to the injury site. The investigators aim to deliver epidural spinal stimulation via an implanted SCS and together with personalized advanced neuro-rehabilitation to study the improvement of neurological function after chronic SCI.

Arm Intervention/treatment
Patients with motor complete chronic spinal cord injury Device: RESToration Of Rehabilitative function with Epidural spinal Stimulation
Three patients with chronic motor SCI will be recruited in total for this study. The recruited patients will not be randomized nor blinded due to the nature of this study. Pre-op rehabilitation session will take place over 4 weeks. 1 month post-surgical implants, patients will undergo 24 weeks of rehabilitation. The training sessions may continue to take place after the stipulated 24 weeks as long the electrode remains implanted, and the patient is available.

Primary Outcome Measures :
  1. Number of participants with treatment-related adverse events assessed by CTCAE v5.0 [ Time Frame: 6 months ]
    The adverse events in patient's with proposed surgical implantation and robotic neuro-rehabilitation during the course of study will be assessed. Particularly, during the first 6 months of the study and post implantation.

Secondary Outcome Measures :
  1. Assessing the improvement in motor outcomes post surgical implantation [ Time Frame: 2 years ]

    Volitional control including independent locomotion with epidural spinal stimulation and robotic neuro-rehabilitation will be assessed to check for improvement in motor functions.

    This assessment will be done during rehabilitation session where the post-surgical movement results will be compared against the pre-surgical results for better understanding and study.

  2. Assessing autonomic function post surgical implantation [ Time Frame: 2 years ]
    The improvement in hemodynamic, bowel and bladder control with epidural spinal stimulation and robotic neuro-rehabilitation will be assessed continuously post surgical implantation
