Psychophysiological impact of spinal cord injury: Depression, coping and heart rate variability.

Faculty: Varsha Singh

Abstract

We examined the association of post-injury heart rate variability (HRV), coping with injury (fighting-acceptance), and depression symptoms in individuals with spinal cord injury (SCI). Participants were grouped based on level of injury (tetraplegic, high paraplegia, and low paraplegia) and injury duration (early vs. late). Odds ratio calculated the risk of depression using HRV and coping as factors for early and late duration groups. Individuals with SCI with high HRV had lower odds of depression (OR = 0.14, CI = 0.03-0.78) than individuals with SCI with low HRV in the early duration group. Individuals with SCI with high acceptance had lower odds of depression (OR = 0.19, CI = 0.44-0.79) than individuals with SCI with low acceptance in the later duration group. In the later duration, HRV ratio negatively correlated with coping ratio in individuals with low paraplegia and depression ratio in individuals with high paraplegia.
