Inclusion Criteria: * Age: = 18 years and = 80 years. * Written informed consent by patient and/or legal authorized representative (LAR). * No other life-threatening condition. * No evidence of sepsis. * No evidence of superficial skin infection at site of surgery and intervention. * An established diagnosis of either: * cervical myelopathy with modified Japanese Orthopaedic Association score of 8-14, or * acute cervical / thoracic SCI with ASIA Impairment Scale grade A-D (as assessed within 72 hours of injury) with neurologic level of injury (NLI) from C2 to T12. * The ability to undergo, or have had, surgical intervention. -. The ability to undergo transcutaneous intervention including study procedures in the posterior cervical or thoracic midline at or after 14 days from surgery. Exclusion Criteria: * Any concomitant impairment of the upper and lower limb at baseline that could potentially confound the neurologic assessments; including but not limited to traumatic or disease conditions like brachial plexus injury, peripheral neuropathy, spinal hematoma, transverse myelitis, non-compressive myelopathy, dementia, and Parkinson's disease. * mJOA of \>= 15 and \<= 7, or AIS grade E tSCI at baseline assessment. * Currently involved in another non-observational ntSCI or tSCI study, or receiving another interventional drug, that could interfere with recordings and confound adverse events. * Other illness (including mental disorder) that could preclude accurate medical and…
