Evidence suggests that neuromodulation technologies can facilitate the sublesional spinal networks after spinal cord injury (SCI) by reestablishing excitability and enabling motor signals via residual connections. This review evaluates the evidence of translesional spinal circuit formation and reorganization after SCI, particularly in the presence of sensory inputs during motor training. The potential mechanisms underlying translesional circuitry reorganization during neuromodulation and rehabilitation are discussed, along with the implications for future development of neuromodulation, rehabilitation, and neuroprosthetics technologies.
Evidence from preclinical and clinical research suggest that neuromodulation technologies can facilitate the sublesional spinal networks, isolated from supraspinal commands after spinal cord injury (SCI), by reestablishing the levels of excitability and enabling descending motor signals via residual connections. Herein, we evaluate available evidence that sublesional and supralesional spinal circuits could form a translesional spinal network after SCI. We further discuss evidence of translesional network reorganization after SCI in the presence of sensory inputs during motor training. In this review, we evaluate potential mechanisms that underlie translesional circuitry reorganization during neuromodulation and rehabilitation in order to enable motor functions after SCI. We discuss the potential of neuromodulation technologies to engage various components that comprise the translesional network, their functional recovery after SCI, and the implications of the concept of translesional network in development of future neuromodulation, rehabilitation, and neuroprosthetics technologies.
