The Importance of Cranial Rhythm and 7 Ways to Help Maintain Proper Motion

Many of us know that babies are born with soft spots where their skull is not fully bone yet. We also know that the skull becomes all bone, therefore the soft spots or fontanelles, close at a certain point in childhood (the last one closes usually around 2 years old). Most of us, however, do not realize that the bones in our head move in a rhythmic motion from before we are born throughout our entire lives, regardless of whether our cranial sutures and fontanelles close. This motion is vital to not only brain and nervous system function, but it is vital for whole body function.

Origins of Cranial Adjusting/Craniosacral Therapy

In the late 1800s and early 1900s, Dr. William Sutherland, an osteopathic doctor, was the first to recognize that the movement of the cranial bones and eventually uncovered a rhythmic fluid motion that encompassed the entire body.  He called this rhythm the “primary respiratory mechanism”. This mechanism includes the rhythmic motion of the cranial bones, nervous system, and spine along with fluctuations in cerebral spinal fluid flow and shifting tension among dural membranes (connective tissue surrounding the brain and nervous system). These movements are all involuntary and completely separate from cardiac pulse and breathing. Dr. Sutherland believed that a skilled practitioner connecting with this primary respiratory mechanism could bring about a therapeutic effect and therefore enhance health.

Many other Doctors and Chiropractors came to understand the importance of cranial motion and developed their own techniques to ensure proper movement. Major Bertrand Dejarnette developed Sacro Occipital Technique. Dr George Goodheart developed Applied Kinesiology. One of the most well-known and heard of techniques is Craniosacral Technique developed by Dr. John Upledger. Over 50 years after Dr. Sutherland, Dr. Upledger discovered this same rhythmic motion in the dural connective tissue while he was preforming surgery. He notice there was movement of the nervous system and dura that was at a different rate than the respiration and cardiac pulse of the patient. He later performed many years of research that became the basis of Craniosacral Technique. This technique allows a practitioner to contact the sacrum as well as the cranial bones, and due to the dural attachement from the cranial bones through the spinal column to the sacrum, correct the primary respiratory mechanism. Both Dr. Sutherland and Dr. Upledger believed that this mechanism was a mechanism that could be used for self-healing, and that at the hands of a skilled practitioner one could see improvements in health.

More recent histological and anatomical examination of the cranial sutures have validated that they are not completely fused and in fact have intricate articulations that allow specific movements. The 106 articulations between the 22 cranial bones all are shaped and connected to allow for the rhythmic motion of the primary respiratory mechanism. This motion occurs 6-12 times per minute. Disruptions in this motion can affect the entire body and cause physical or emotional symptoms. Dural or fascial restrictions can affect cranial nerve function and stimulation. It can also affect cerebral spinal fluid flow and therefore impact the nutrient and water distribution to different areas of the brain, spinal cord and peripheral nerves. For example, dural tissue attached at the temporal bones is contiguous with fascia of the carotid sheath (this contains part of the vagus nerve), the fibrous pericardium (around the heart), and the respiratory diaphragm. Therefore, a restriction in the dural tissue at the temporal bone can affect vagal stimulation as well as cardiac and respiratory function.

A well-functioning primary respiratory mechanism allows for full cranial and dural movement, as well as proper cerebral spinal fluid fluctuation. With this mechanism working properly, there is no interference occurring in the nervous system and no areas of restriction that would hinder function in the body. However, many things can disrupt this primary respiratory mechanism and cause alterations in cranial motion and positioning. Adhesions and areas of restriction and congestion develop which can have a negative effect on the way the body functions. There are, however, things that you can do to allow for proper cranial motion in your own child.

7 Ways to Help Maintain Proper Motion

1)     Cranial Adjustments

Baby’s cranial bones are very moldable and easily shaped. Often times, babies will be born with cranial bones that have molded quite a bit. This could be from the way they were resting in the uterus or because of the pressures placed upon the cranium during labor and delivery. Nursing can play a huge role in helping initially increasing cranial motion to help return the cranium to a symmetrical and round shape. However, most of the time a trained therapist is needed to ensure that all of the cranial bones are moving properly and there are no overlaps in the sutures or dural tightness and adhesions preventing motion. Chiropractors who are certified by the ICPA are proficient in cranial adjusting as well as therapists trained in Craniosacral Technique. There are many other techniques that can be affective in cranial manipulation such as Sacro Occipital Technique and Applied Kinesiology. Making sure that you find someone who has been trained in cranial adjusting and someone who is comfortable and confident in adjusting cranial bones is important.

Cranial adjusting, as mentioned above not only can bring proper symmetry, shape, and motion to the bones of the skull, but can affect whole body function and can have a positive effect on issues such as colic, digestive issues, reflux, sinus issues, ear infections, sleep issues, etc. Cranial manipulation can impact vagal stimulation and increase parasympathetic activity. This can decrease inflammation in the gut and improve digestive, respiratory, and cardiac function.

2)     Breastfeeding

Breastfeeding is extremely good for many reasons. One of those reasons is that it can help proper development of the cranial bones and mandible.  The sucking motion required for breastfeeding flattens the breast tissue up against the palate which helps shape and mold the roof of the mouth which is also the bottom of the sinus cavity. Breastfeeding allows for optimal shaping of the palate so it is smooth and rounded and not too high and narrow. High and narrow palates will cause the sinus cavity to become smaller and narrower.  This can lead to future sinus issues.  The sucking motion that presses the breast tissue into the palate helps to move the cranial bones and stimulate growth centers in the facial bones. Typically with breastfeeding the baby is held in different positions and he or she nurses on both breasts so the growth centers on each side of the cranial and facial bones are stimulated evenly. This sucking motion also aids in cerebral spinal fluid flow and helps to stimulate pituitary hormone release particularly growth factors.

3)     Lip and Tongue Tie Release

It is seemingly becoming more and more prevalent these days to see a baby with a lip and/or tongue tie. A lip tie is present when the frenulum or connective tissue between the upper lip and gum is overdeveloped and restrictive to the movement of the upper lip.  A tongue tie is present when the lingual frenulum or connective tissue between the bottom of the tongue and the lower jaw is overdeveloped and restrictive to the movement of the tongue.  Lip and tongue ties are thought to be genetic and are midline defects that are associated with genetic abnormalities that impact the body’s ability to methylate, such as MTHFR. Lip and tongue ties can vary greatly in degree and effect on function.  Lip and tongue ties restrict the function of the oral cavity. They affect the amount the jaw can open, the strength, movement and function of the tongue, and the movement, development and growth of the cranial bones. The restriction in the connective tissue extends deeper into the connective fascia that surrounds the cranium, jaw and can affect the tissue extending into the neck, shoulders, and even into the diaphragm, abdomen, hips and legs. Releasing the tongue and lip tie can have greatly relieving effect for a newborn. It is wise to have cranial adjustments, craniosacral therapy, or other fascial release technique performed after the tongue and lip tie release to ensure that all the connective tissue restrictions are released and full function is restored. The tongue tie and lip tie can be release through the use of scissors or through a cutting laser. It is recommended that each parent do their research in determining which method of treatment is available and most beneficial for their child. Release of these ties will help to encourage proper cranial and mandible development and growth. It will allow for proper growth center stimulation in the facial and cranial bones. It will also encourage full cranial rhythm and movement allowing for proper cranial and facial symmetry.

4)     Babywearing

Wearing your baby in a carrier, sling or wrap is beneficial in numerous ways including supporting cranial shape and motion. Babywearing allows the child to be upright off the floor or out of a seat so there is no risk of developing a “flat spot” from lying in one position for prolonged periods of time. The upright posture also encourages suboccipital muscle development to aid in proper occipital alignment upon the atlas (first vertebrae in the neck). Babywearing also has been connected to extended breastfeeding.  The suckling required for breastfeeding increases cranial movement and also stimulates growth centers among the facial bones allowing for full functional growth of the facial bones and mandible.

5)     No Contraptions

Coinciding with babywearing, keeping babies out of contraptions like car seats, bouncy seats and swings will benefit the cranial bones and the primary respiratory mechanism. Contraptions like car seats limit the baby’s range of motion and confine the baby to typically lay in the same position with the same consistent pressure on the same area of the skull. It only takes less than 5grams of pressure to move and influence cranial motion. So if a baby is laying in the same position with the same pressure for extended periods the cranial bones will mold to fit that pressure. This is typically how flat spots develop, and the skull should not have flat spots. Flat spots indicate that there is altered shape and motion to the different cranial bones. This affects the cerebral spinal fluid movement and can lead to adhesions in the dural tissue causing other symptoms. If flat spots do develop despite your best effort to not have them in a car seat or other contraption for long periods, then finding a practitioner who can perform craniosacral technique or other means of cranial adjusting is recommended.

6)     No Headbands or Bows

Having two little girls myself, I know that a headband with a big bow or flower on it can look very cute. However, like I mentioned above, it takes less than 5grams of pressure to influence the cranial bones shape and motion. So placing a tight headband that constricts the cranium will not only change the shape of the head but will decrease the movement of the cranial bones and negatively impact the primary respiratory mechanism. Many parents who have little girls who are bald for a long time will want to always have a headband on their baby since they can not clip on bows to her hair. This will always constrict motion of the cranial bones and work towards altering the shape of the cranium. Typically a headband will wrap around the occiput, temporal, sphenoid and frontal bones. Even slight alterations in the shape or motion of the occiput can cause misalignments in any other cranial bone. This again will cause adhesions in the dura and affect the nutrient saturation of the nervous system. One lesser evil that I encourage moms to do is to keep the headband or bow in your bag and only slip it on for pictures and then take it right back off. Look for red marks and signs of the bow on the head after you take it off. The more marks and redness you see left behind after the bow is off tells you there is more pressure being applied by the headband. Bows and headbands look cute, but have a huge impact on the shape and motion of the cranium.

7)     Vary Sleeping Positions

Many times parents will place their baby in a crib, basinet, or co-sleeper for naps and bedtime. These devices then stay in the same place and the baby is placed in the same position in them. This can cause the baby to develop a flat spot from continual pressure in one area. The baby will often develop a more comfortable sleeping position they prefer to obtain while in the crib or sleeper. Moving the crib around the room or placing the baby in the crib facing the opposite direction will help to vary the position the baby maintains during sleep. It will also give variability to what side the baby is approached from when he or she wakes up. Therefore the baby will not grow accustom to turning one way to wait for mom or dad when he or she wakes up. Altering sleeping positions for the baby will give him or her varied stimulation and change the way pressure is placed on the head due to the direction he or she will look depending on the position of the crib or sleeper. Back sleeping has been supported by the American Pediatric Association to help prevent SIDS but this campaign has also contributed to flat spots due to back sleeping. Ensuring that there are varied sleeping positions and plenty of tummy time is vital to maintaining cranial symmetry and function if the parent chooses to encourage back sleeping.

 

Many things can contribute to proper cranial motion and function. These suggestions can help parents to take actionable steps towards improving their child’s health through properly functioning cranial movement and rhythm.
