An interventional study of 4th Ventricular Compression Technique and "Sham" Therapy in Healthy, sponsored by Escola Superior de Tecnologia da Saúde do Porto. Not yet recruiting at 1 site in Portugal. Open to participants aged 18 Years to 25 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-04-29.
Sponsored by Escola Superior de Tecnologia da Saúde do Porto · Not applicable, Interventional, and Other
Determinate the effects of the technique of 4th ventricle in college students with anxiety, applying the technique one time per week during three weeks.
The anxiety is a warning sign that makes it possible for the individual to defend themselves and protect themselves from threats. This is considered a natural and necessary reaction for self-preservation. However, when it appears persistently, exaggeratedly or disproportionately in relation to a stimulus, the following are considered: pathological anxiety.
The compression of the fourth ventricle (CV4) is one of the most well-known procedures in the practice of cranial manipulation. It is also one of the most clinically tested techniques and has been postulated to be associated with decreased sympathetic tone.
Therefore, this was the chosen technique, as it significantly affects the relaxation of the SNS tonus and, thereafter, anxiety.
Escola Superior de Tecnologia da Saúde do Porto is the lead sponsor of 37 studies on the registry; 20 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
The technique was preformed by the investigator during 5 minutes.
Other: 4th Ventricular Compression Technique
The technique was preformed by the investigator during 5 minutes.
Other: "Sham" Therapy
The investigator who applied the technique stood on top of the headboard of the table, with feet flat on the floor, at an appropriate level in relation to the volunteer's headboard. The investigator joins hands in a cupping position, with the pads of the 1st fingers forming a triangle. The pads of the 1st fingers make contact with the spinous processes of the 2nd and 3rd cervical vertebrae. The thenar eminences make contact with the occipital squama, avoiding contact with the occipito-mastoid sutures during 5 minutes. A second Investigator was sitting on a chair, placed on the opposite side of the head of the table with a stopwatch in his dominant hand, in order to time the application time of each technique.

Change from baseline in anxiety levels through the STAI (The State-Trait Anxiety Inventory) questionnaire score on the 1st and last intervention.
The participants were submitted to a evaluation 1 week prior the 1st and 1 week after the last intervention. The corresponding questionnaires were sent to the researchers so that they could record the information. Quoted with a min. of 20 points and a max. of 80 - higher the score worst level of anxiety.
Time frame: One week after the last intervention
Change from baseline in thoraco-abdominal perimetry on the 1st and last intervention
The participants were submitted to a evaluation/ measurement in the 1st and last intervention. The corresponding results were registered by the researchers so that they could record the information.
Time frame: Immediately after last intervention
