Outcome Measures
Primary Outcomes (2)
Change from Baseline in heart rate variability immediately after the intervention
To obtain the heart rate measurements, a pulse volume sensor (Biosignalsplux researcher) was connected to the third finger of the hand, with the patient lying supine. The sensor was only removed after completing all the evaluation moments.
Immediately after the intervention.
Change from Baseline in heart rate variability 15 minutes after the intervention
To obtain the heart rate measurements, a pulse volume sensor (Biosignalsplux researcher) was connected to the third finger of the hand, with the patient lying supine. The sensor was only removed after completing all the evaluation moments.

Study Arms (2)
CV-4 group
EXPERIMENTALThe initial selection will be made through a questionnaire, in order to fulfill the exclusion and inclusion criteria. On the data collection day a more detailed survey is performed and informed consent is signed. The patient waits for 5 minutes in the supine position, after which the baseline evaluation is performed. The CV-4 technique is performed following immediate evaluation. 15 minutes after the technique, a new evaluation of the variables is accomplished.
Control group
SHAM COMPARATORThe initial selection will be made through a questionnaire, in order to fulfill the exclusion and inclusion criteria. On the data collection day a more detailed survey is performed and informed consent is signed. The patient waits for 5 minutes in the supine position, after which the baseline evaluation is performed. The sham technique is performed following immediate evaluation. 15 minutes after the technique, a new evaluation of the variables is accomplished.
Interventions
The participant is in the supine position and the principal investigator is seated at the patient's head, with elbows resting on the table. The main investigator overlaps his hands with the thenar eminences, contacting the occipital bone squamous part, between the external occipital protuberance and the participant's occipito-mastoid suture. The technique begins with a maintained compression on the occipital squamous part during a deep thorax exhalation. Throughout the compression of the occipital bone and the participant's voluntary inspirations, the principal investigator feels a gradual pressure increase at the thenar eminences. The technique will be performed until reaching the still point, in which the mobility of the occipital bone, respiratory rate and muscle tone decrease, or until 5 minutes elapsed.
The main investigator uses the technique contact but does not perform any type of tissue traction or compression, maintaining this contact for 5 minutes. At the end of the stipulated time, the contact is removed in a subtle way.
Eligibility Criteria
You may qualify if:
- Healthy participants aged between 18 and 33 years.
You may not qualify if:
- Cognitive deficits that can possibly compromise the understanding of the study instructions;
- Any type of medication taken that may have influences at the variables under study in the previous 7 days;
- Cranio-cervical injuries, surgery to the skull and /or spine in the last 12 months;
- Chronic cardiorespiratory, renal, systemic, neurological, musculoskeletal, oncological and psychiatric pathologies;
- Headaches, migraines, dizziness and / or nausea while performing the techniques;
- Caffeine and / or alcohol intake in the 6 hours prior to the data collection;
- Tobacco consumption in the 30 minutes prior to the data collection;
- Practice of intense physical exercise in the 90 minutes prior to the data collection;
- Pregnant women or menstruating;
- Participants who were submitted to manual therapy treatments during the past month;
- Osteopathy students of 3rd year or higher degree, in order to prevent the participant from recognizing which group they belong to.
