采用心率变异性（HRV）指标的线性判别分析，本研究旨在验证自主测量的有效性，在重性抑郁症（MDD）患者的病假后，通过评估他们返回工作岗位的可行性。当计划恢复时，使用可穿戴心电图设备测量患者的HRV。在恢复工作后一个月评估恢复的结果。HRV指标包括高，低频成分计算在三个条件下的会话：初始休息，脑力劳动，休息后的任务。一个线性判别函数，从我们以前的研究中使用的30例MDD患者的HRV指标，以有效地区分成功的恢复不成功的恢复，然后在52例患者参加了本研究进行了测试。判别函数显示，判别成功与失败退货的敏感性和特异性分别为95.8%和35.7%。敏感性高，表明正常的HRV是需要一个成功的回报，和HRV指标的判别分析是有用的MDD患者返回工作筛选。另一方面，特异性较低，表明其他因素也可能影响恢复的结果。
Using a linear discriminant analysis of heart rate variability (HRV) indices, the present study sought to verify the usefulness of autonomic measurement in major depressive disorder (MDD) patients by assessing the feasibility of their return to work after sick leave. When reinstatement was scheduled, patients’ HRV was measured using a wearable electrocardiogram device. The outcome of the reinstatement was evaluated at one month after returning to work. HRV indices including high- and low-frequency components were calculated in three conditions within a session: initial rest, mental task, and rest after task. A linear discriminant function was made using the HRV indices of 30 MDD patients from our previous study to effectively discriminate the successful reinstatement from the unsuccessful reinstatement; this was then tested on 52 patients who participated in the present study. The discriminant function showed that the sensitivity and specificity in discriminating successful from unsuccessful returns were 95.8% and 35.7%, respectively. Sensitivity is high, indicating that normal HRV is required for a successful return, and that the discriminant analysis of HRV indices is useful for return-to-work screening in MDD patients. On the other hand, specificity is low, suggesting that other factors may also affect the outcome of reinstatement.
