TITLE: Effects of indirect osteopathic techniques on heart rate variability (HRV) – nonlinear analysis included – and on electrodermal activity in “healthy” adults. The RILHOU randomized clinical trial. RESEARCH TITLE: Effect of a CV4 cranial osteopathic technique on HRV and on electrodermal activity in a cohort of “healthy” adults.
BACKGROUND: Heart rate variability (HRV) is a reliable method for measuring the activity of the sympathetic and parasympathetic system. The compression of the fourth ventricle (CV4) is commonly used in osteopathic clinic. Literature suggests that the CV4 has an effect on the autonomic nerve system. OBJECTIVE: To investigate the effect of a CV4 cranial technique on HRV and electrodermal activity (EDA) in healthy adults. METHOD: The experimental group underwent a CV4 technique and the sham group received 3 different hands on techniques. The measurements were done before (t0), immediately after (t1) and 7 till 10 days after the experiment (t2) using an ambulant ECG device (VU-AMS). The parameters of HRV were analysed in three domains: time domain, frequency domain and non-linear methods. EDA was analysed using skin conductance level (SCL). RESULTS: Total population of thirty subjects (N=30, 19 female and 11 male) were divided into an experimental group (N=16, 12 female and 4 men, 27,2 ±2,51 years of age, BMI 22,74 ±3,00 kg/m²) and sham group (N=14, 7 female and 7 men, 30,21 ±6,82 years of age, BMI 23,11 ±3,01 kg/m²). The Mann Whitney test showed no significant difference in baseline between the two groups (MW-U: p > 0.05). The Wilcoxon signed ranks test showed a significant treatment effect in the experimental group, at t1 compared with t0, for two variables of HRV: apen (p=0.039) and dfa (p=0.008). In the sham group the Wilcoxon signed ranks test showed a significant effect at t1 compared with t0, for LF_ms (p=0,008), HF_ms (p=0,013), sd2 (p= 0,009) and d2 (p= 0,035) and at t2 compared with t1 for Respiration_Rate (p= 0,041). For the following variables there was a significant treatment and sham effect at t1 compared with t0: SDNN_msec (p= 0,017 treatment, p= 0,004 sham), StdDev_HR_bpm (p= 0,030 treatment, p= 0,026) and Average_SCL_uS (p= 0,002 treatment, p= 0,002 sham). The ANCOVA test do not show significant effects between the groups on different time periods. DISCUSSION: The variables showing significance using the Wilcoxon signed ranks test do not show significance in the ANCOVA test. CONCLUSION: This study did not show significant effects in HRV and EDA. The CV4 technique does not have short-term and long-term influence on the HRV and EDA compared with sham intervention in “healthy” adults.
