The Influence of Exercise on Oxidative Stress after Spinal Cord Injury: A Narrative Review

Spinal cord injury (SCI) is an irreversible disease resulting in partial or total loss of sensory and motor function. The pathophysiology of SCI is characterized by an initial primary injury phase followed by a secondary phase in which reactive oxygen species (ROSs) and associated oxidative stress play hallmark roles. Physical exercise is an indispensable means of promoting psychophysical well-being and improving quality of life. It positively influences the neuromuscular, cardiovascular, respiratory, and immune systems. Moreover, exercise may provide a mechanism to regulate the variation and equilibrium between pro-oxidants and antioxidants. After a brief overview of spinal cord anatomy and the different types of spinal cord injury, the purpose of this review is to investigate the evidence regarding the effect of exercise on oxidative stress among individuals with SCI.

Automated summary

Spinal cord injury (SCI) leads to sensory and motor function loss. The pathophysiology of SCI involves primary and secondary phases, with oxidative stress playing a significant role in the secondary phase. Exercise is crucial for promoting well-being and quality of life, impacting various systems and potentially regulating the balance between pro-oxidants and antioxidants. This review aims to investigate the effects of exercise on oxidative stress in individuals with SCI, following an overview of spinal cord anatomy and different types of injury.
