Brief summary
Cranial osteopathic manipulation technique for brain and cranial nerve function, known as the fourth ventricle compression (CV4), has been recognized. Rib raising (RR), aimed at reducing rib restriction and conditions associated with sympathetic hypertonia, is also employed. This study aimed to assess, in about 109 healthy individuals, the effects of osteopathic techniques (CV4 and RR) on autonomic nervous system (ANS) activity, as measured by heart rate variability (HRV).
Detailed description
In this planned study, 109 healthy subjects will be randomly assigned to one of three groups. A total of 90-100 participants are expected to complete all stages of the study, and their data will be used in the final analysis. The first experimental group will undergo three 30-minute sessions of osteopathic therapy, including the CV4 and RR techniques. The second group will receive three 30-minute sessions of the CV4 technique alone. The placebo group will undergo a sham procedure using an ultrasound transducer. To evaluate the impact of these osteopathic techniques on autonomic nervous system (ANS) function, Heart Rate Variability (HRV) will be measured using an EEG/HRV/RSA Infiniti 8 device, ProComp Infiniti encoder, and Biograph Infiniti and Physiology Suit software. Measurements will be conducted in a seated position over a 5-minute duration.
Interventions
Participants in this group will undergo three 30-minute sessions of osteopathic therapy. The intervention will involve a combination of the Fourth Ventricle Compression (CV4) technique and the Rib Raising (RR) technique. These sessions will be administered once per week over three consecutive weeks. The CV4 technique involves gentle compression of the occiput to influence cranial rhythmic impulses, while the RR technique involves mobilization of the rib cage to impact autonomic nervous system function.
Participants in this group will receive three 30-minute sessions focusing solely on the Fourth Ventricle Compression (CV4) technique. The sessions will be conducted once per week for three consecutive weeks. The CV4 technique involves applying gentle pressure to the occiput with the goal of affecting cranial rhythmic impulses and promoting autonomic nervous system balance.
Participants in the placebo group will undergo three 30-minute sessions of a sham procedure using an ultrasound transducer. The transducer will be applied in a manner that mimics a therapeutic intervention, but without delivering any actual therapeutic effect. These sessions will also be conducted once per week for three consecutive weeks.
Participants in the placebo group will undergo three 30-minute sessions using an ultrasound transducer as part of a sham procedure. The transducer will be applied to the body in a manner that mimics a therapeutic intervention, but it will not deliver any actual therapeutic effect. This procedure is designed to simulate the experience of receiving treatment without providing the physiological benefits associated with active ultrasound therapy. The sessions will be conducted once per week over three consecutive weeks.
Participants in this study will undergo monitoring of Heart Rate Variability (HRV), and Respiratory Sinus Arrhythmia (RSA) using the Infiniti 8 measuring device. This system includes a ProComp Infiniti encoder, which is a versatile and advanced tool for capturing physiological signals, and the Biograph Infiniti software, which, along with the Physiology Suit, allows for detailed analysis and monitoring of autonomic nervous system function.

Study design
Masking description
This study will employ a single-blind design, where participants will be unaware of the specific intervention they receive. However, the investigators and care providers will be informed about the group assignments to ensure proper administration of the interventions. Blinding will be maintained throughout the study to prevent participant bias.
Intervention model description
n this study, 109 healthy subjects will be randomly assigned to one of three groups. The first experimental group will receive three 30-minute sessions of osteopathic therapy using both CV4 and RR techniques. The second group will undergo three 30-minute sessions of the CV4 technique alone. The placebo group will undergo a sham procedure using an ultrasound transducer. To assess the impact of these interventions on autonomic nervous system (ANS) function, Heart Rate Variability (HRV) will be measured using specialized equipment in a seated position over a 5-minute duration.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Heart Rate Variability (HRV) | Measurements will be taken at three time points: before the intervention (baseline), immediately after the third session (post-intervention), and one month after the final session (follow-up). | Changes in Heart Rate Variability will be assessed to evaluate the overall autonomic nervous system (ANS) function. HRV will be measured using the standard deviation of normal-to-normal intervals (SDNN) and other relevant time-domain and frequency-domain parameters. Measurements will be taken before the intervention, immediately after the third session, and one month after the final session to evaluate both immediate and sustained effects. |
| High-Frequency Power (HF) | Measurements will be taken at three time points: before the intervention (baseline), immediately after the third session (post-intervention), and one month after the final session (follow-up). | The HF component of HRV, which reflects parasympathetic (vagal) activity, will be measured. Changes in HF power will indicate the impact of the osteopathic techniques on parasympathetic regulation. HF power will be expressed in absolute units (ms²) and as a normalized unit. |
| Low-Frequency Power (LF | Measurements will be taken at three time points: before the intervention (baseline), immediately after the third session (post-intervention), and one month after the final session (follow-up). | The LF component of HRV, associated with both sympathetic and parasympathetic activity, will be assessed. LF power will be measured to understand its modulation through the interventions. LF power will be reported in absolute units (ms²) and as a normalized unit. |
| LF/HF Ratio | Measurements will be taken at three time points: before the intervention (baseline), immediately after the third session (post-intervention), and one month after the final session (follow-up). | The ratio of LF to HF power (LF/HF) will be analyzed as an indicator of the balance between sympathetic and parasympathetic nervous system activity. This measure will help determine the relative predominance of each branch of the autonomic nervous system in response to the osteopathic interventions. |
