ABSTRACT

Study of Relationship between Autonomic Nerve System and Post Stroke Insomnia by Heart Rate Variability Jae-Heung Cho, O.M.D., Dong-Jae Shin, O.M.D., Jong-Soo Lee, O.M.D., Sung-Soo Kim, O.M.D. Dept. of Oriental Rehabilitation Medicine, College of Oriental Medicine, Kyung-Hee University Objectives : This study was designed to evaluate the effect of imbalance of autonomic nerve system on post-stroke patients with insomnia by Heart Rate Variability parameters. Methods : Sample group of 15 patients with post stroke insomnia was tested Heart Rate Variability parameters which are Mean Heart Rate(MHRT), Standard Deviation of all the Normal RR intervals(SDNN), Root Mean Square of Successive Differences Between The Normal Heart Beats(RMSSD), Total Power(TP), Low Frequency(LF), High Frequency(HF) and LF/HF ratio. This results were compared with that of control group including 15 patients without post stroke insomnia. Results : 1. MHRT and LF/HF ratio were not significantly different between sample group and control group(P=0.061, 0.305). 2. SDNN and RMS-SD were significantly different between sample group and control group(P=0.013, 0.029). 3. TP, HF and LF of sample group were significantly different compared with those of conrol group(P=0.023, 0.037, 0.037). Conclusions : General parameters of Heart Rate Variability except MHRT and LF/HF ratio were dropped off in activity. This result means that post stroke insomnia was affected more by secondary factors than simple stress due to environmental change.
