The aim was to examine the association of post-injury heart rate variability (HRV), coping with injury (fighting-acceptance), and depression symptoms in individuals with spinal cord injury (SCI). Cross-sectional study. Tertiary care spinal cord injury hospital. Ninety-one individuals with SCI. All participants were assessed for HRV using polar heart rate monitor RS 800 CX and completed the Patient Health Questionnaire and Spinal Cord Lesion Coping Strategy questionnaire. 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. Spearman rho estimated the correlation between three ratios: HRV (LF vs. HF), depression (somatic vs. cognitive), and coping (fighting spirit vs. acceptance) for each level of injury group for early and late duration. 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. The aftermath of spinal cord injury might reflect a close association between the physiological response of autonomic variability and psychological response of coping and depression with implications for the level of injury and post-injury duration.
目的是研究脊髓损伤（SCI）个体受伤后心率变异性（HRV）、应对损伤（战斗-接受）和抑郁症状之间的关系。横断面研究。三级脊髓损伤医院。91 名 SCI 患者。所有参与者均使用 Polar 心率监测仪 RS 800 CX 评估 HRV，并完成了患者健康问卷和脊髓损伤应对策略问卷。根据损伤水平（四肢瘫痪、高位截瘫和低位截瘫）和损伤持续时间（早期和晚期）对参与者进行分组。使用 HRV 和应对作为早期和晚期持续时间组的因素，计算比值比（OR）来评估抑郁的风险。Spearman rho 估计了三个比值（HRV（LF 与 HF）、抑郁（躯体与认知）和应对（斗志与接受））之间的相关性，对于每个损伤水平组的早期和晚期持续时间。在早期持续时间组中，HRV 较高的 SCI 患者患抑郁的几率较低（OR=0.14，CI=0.03-0.78），HRV 较低的 SCI 患者患抑郁的几率较高。在晚期持续时间组中，高接受度的 SCI 患者患抑郁的几率较低（OR=0.19，CI=0.44-0.79），而低接受度的 SCI 患者患抑郁的几率较高。在晚期持续时间，HRV 比值与低截瘫患者的应对比值呈负相关，与高截瘫患者的抑郁比值呈负相关。脊髓损伤后的后果可能反映了自主变异性的生理反应与应对和抑郁的心理反应之间的密切关联，这与损伤程度和受伤后持续时间有关。
