Abstract

BACKGROUND : Neurotraumatic conditions, such as spinal cord injury, brain injury, and neurodegenerative conditions, such as amyotrophic lateral sclerosis, pose a challenge to the field of rehabilitation for its complexity and nuances in management. For decades, the use of cell therapy in treatment of neurorehabilitation conditions have been explored to complement the current, mainstay treatment options; however, a consensus for standardization of the cell therapy and its efficacy has not been reached in the medical community. This study aims to provide a comparative review on the very topic of cell therapy use in neurorehabilitation conditions in an attempt to bridge the gap in knowledge. METHODS : Studies were searched from the PubMed database published from 2014 to 2024 employing the terms including but not exclusive to “spinal cord injury,” “brain injury,” “amyotrophic lateral sclerosis,” “regenerative medicine,” “cell therapy,” and “stem cell.” Following the PRISMA 2020 statement, the studies were screened, included, and excluded. Thirty three studies were identified and selected for this review. RESULTS : Countless researchers investigated the efficacy of various stem cell products for the treatment of numerous neurotraumatic conditions, such as spinal cord injury, traumatic brain injury, and neurodegenerative conditions such as amyotrophic lateral sclerosis. The recent decade of studies suggest that in neurotraumatic conditions, bone-marrow-derived and neural stem cells can be effective, and in neurodegenerative conditions, such as ALS, mesenchymal and neural stem cells can be efficacious. CONCLUSION : Emerging data from the latest research is encouraging to the patients suffering from neurotraumatic and neurodegenerative conditions, which present themselves as a need for further studies with improved standardization in study design, including cell source specification, differentiation and culture method, and outcome measures to ensure a wide applicability.
