Guttmann NeuroRecovery - Viability, Safety, and Efficacy of Intrathecal Wharton's Jelly Mesenchymal Stem Cells and Transcutaneous Spinal Cord Stimulation in Chronic Spinal Cord Injury Rehabilitation

This clinical trial primarily aims to evaluate the safety and feasibility of a combined therapeutic approach for chronic spinal cord injury (SCI). The study will investigate whether the combination of intrathecal Wharton's jelly mesenchymal stem cells and transcutaneous spinal cord stimulation (tSCS) is safe and viable in individuals with chronic traumatic SCI. The trial will enrol 10 participants aged 16-70 with traumatic SCI (cervical or thoracic levels C1-T12) classified as ASIA Impairment Scale A-C, who are 1-5 years post-injury. Participants will receive three intrathecal injections of Wharton's jelly mesenchymal stem cells, each containing 30 million viable cells (±30%), administered intrathecally at the L3-L4 level. This cellular therapy will be combined with transcutaneous spinal cord stimulation and intensive neurorehabilitation. Participants will undergo comprehensive assessments over a 12-month follow-up period to monitor safety, feasibility, and secondarily to evaluate potential improvements in motor, sensory, and autonomic functions. Additional annual follow-up will continue for 2 years after study completion to evaluate long-term safety.
