Heart rate variability (HRV) may provide an index of capacity for social functioning and may be remediated by HRV biofeedback. Given reductions in HRV are found following traumatic brain injury (TBI), the present study aimed to determine whether lower HRV in TBI is associated with social function, and whether HRV biofeedback might be a useful remediation technique in this population. Resting state HRV and measures of social and emotional processing were collected in 30 individuals with severe TBI (3-34 years post-injury) and 30 controls. This was followed by a single session of HRV biofeedback. HRV was positively associated with social cognition and empathy, and negatively associated with alexithymia for the TBI group. Both TBI and control groups showed significantly increased HRV on both time-domain (i.e., SDNN, rMSSD) and frequency-domain measures (LF, HF, LF:HF ratio) during biofeedback compared to baseline. These results suggest that decreased HRV is linked to social and emotional function following severe TBI, and may be a novel target for therapy using HRV biofeedback techniques.
心率变异性（HRV）可能提供社会功能能力的指标，并且可能通过HRV生物反馈得到改善。鉴于创伤性脑损伤（TBI）后发现HRV降低，本研究旨在确定TBI中较低的HRV是否与社会功能相关，以及HRV生物反馈是否可能是该人群中一种有用的改善技术。收集了30名重度TBI患者（受伤后3 - 34年）和30名对照者的静息状态HRV以及社会和情感加工测量指标。随后进行了一次HRV生物反馈治疗。对于TBI组，HRV与社会认知和同理心呈正相关，与述情障碍呈负相关。与基线相比，TBI组和对照组在生物反馈期间的时域（即SDNN、rMSSD）和频域测量指标（LF、HF、LF:HF比值）上的HRV均显著增加。这些结果表明，重度TBI后HRV降低与社会和情感功能有关，并且可能是使用HRV生物反馈技术进行治疗的一个新靶点。
