Comparison of Heart Rate Variability Biofeedback Intervention for Different Types of Insomnia Disorder / 中国康复理论与实践

ABSTRACT

Objective To investigate the effect of heart rate variability (HRV) biofeedback training on patients with three types of insom-nia disorder. Methods From June, 2016 to March, 2017, 17 patients in simple insomnia group, 19 patients in insomnia with anxiety group, and 19 patients in insomnia with depression group were included. All the patients received HRV biofeedback training and same medication (zolpidem tartrate, 10 mg every night). They were assessed with Pittsburgh Sleep Quality Index (PSQI), Symptom Checklist 90 (SCL-90), Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD), and HRV parameters were tracked before and after training. Re-sults After training, the scores of PSQI, SCL-90, HAMA , HAMD and the ratio of low frequency (LF) and high frequency (HF) (LF/HF) de-creased in all groups (t>1.446, P0.05). Conclusion HRV biofeedback training could improve the symptoms of patients with three types of insomnia disorder, especially for those with anxiety or depression.
