Summary

Osteopathic medicine is based on a diagnostic and therapeutic system to treat tissue mobility/ motility dysfunctions in general, using different approaches (depending on the target tissue) known as osteopathic manipulative treatment. Among all the available techniques those ones addressed to the cranial field are most questioned because of the lack of scientific evidence; but the compression of the 4th ventricle technique has been largely studied in clinical trials. Studies have shown that the technique may affect both central and autonomous nervous system, modulating some reflexes (Traube-Hering baro signal), and modifying brain cortex electrical activity through central sensitization in subjects with chronic low back pain. Thus, investigators hypothesize that the compression of the 4th ventricle may modulate peak alpha frequency (electroencephalographic assessment) and promote physical relaxation in subjects in vigil.

Detailed description

A randomized controlled crossover trial with blinded assessor was designed to test the hypothesis. A total of 81 participants will be assigned to three treatment conditions, with seven days of washout: compression of the 4th ventricle group; sham compression of the 4th ventricle group; control group (no intervention). All participants will be recruited at the Outpatient Rehabilitation Service of the University Hospital of Brasília - University of Brasília (Brazil).

Conditions

• Low Back Pain

Interventions

Type	Name	Description
OTHER	CV4 Cranial (4th ventricle technique) Osteopathic Manipulative	The participant will be in supine position during the whole procedure. The practitioner sits behind the participant's head, contacts participant's lateral protuberances of the squama occipitalis (medially to the occipitomastoid suture) with the thenar eminence of both hands. When the practitioner feels the PRM (a pulsating rhythm caused by liquor production and reabsorption), the flexion phase will be resisted and the extension phase exaggerated. The compressive force is held until the PRM stops (event known as 'Still point'). The compression will be held until the practitioner feels PRM gradual return; the compression will be slowly diminished, and then, the practitioner remove the hands from the occipital bone, laying the participant's head on the table. The CV4 technique will be performed by an osteopath D.O. - member of the Brazilian Register of Osteopaths.
OTHER	CV4 (4th ventricle technique) manual therapy sham technique	The participant will be in supine position and the practitioner will be seated behind the participant's head. The practitioner places the fingers (2nd to 5th) under the occipital bone, touching only the squama occipitalis. The practitioner will hold this position for 5 minutes, and after this period the participant's head will be placed on the table. The CV4 sham will be performed by a registered physiotherapist.
