The V-spread technique is a cranial osteopathic manipulative treatment that is used to free restrictions of cranial sutures and is most commonly used for the occipitomastoid (OM) suture. This technique involves the placement of the physician's index finger on one side of the suture and their middle finger on the other side of the suture creating a small V with the two fingers. The fingers press into the tissues with enough pressure to move bony tissue and not the overlying soft tissue. The physician's fingers then slowly spread apart creating a slightly larger V. Once the tissues have softened the suture is rechecked and if appropriate motion has not been restored the technique is repeated.

Bulb decompression or CV4 is commonly used to reset the amplitude of the cranial rhythmic impulse (CRI) through the creation of a still point but does not specifically address an occipitomastoid restriction.

Vault hold is commonly used by practitioners to monitor and diagnose the CRI and address strains of the SBS. The vault hold is a particular positioning of the hands and is not itself a treatment.

Venous sinus technique is used to increase the blood flow through the venous sinuses of the skull and out through the jugular foramen. It is not designed to correct a specific cranial suture restriction dysfunction as in this case and does not involve the occipitomastoid suture.
