Researched and developed with the world-renowned University at Trinity College in Dublin, our advanced ClevaFoam® technology is specifically engineered, designed and manufactured for babies. It supports your baby’s rapidly growing body and developing joints, it protects the round shape of your baby’s soft head to help prevent Plagiocephaly (Flat Head Syndrome), which is common in young babies.
It is the only product scientifically proven to reduce pressure on the back of a baby’s head by 50% and to increase support by 80% (Trinity College, University of Dublin, Ireland). Hyper-allergenic, pH balanced and toxin free it is ideal for babies and children with asthma and allergies.
WHAT IS PLAGIOCEPHALY?
Deformational Plagiocephaly (DP) is a medical condition, more commonly known as ‘flat head syndrome’ (FHS), which occurs when an infant’s head becomes flatten and or misshaped due to the head continually resting on a surface that does not conform or support the shape of a baby’s head. Infant heads are soft to allow for the initial passage through the birth canal and then for the incredible brain growth that occurs in the first year of life. During the early months of life, they are more susceptible to being "molded" into a flat shape or taking the form of the surface that the skull is in contact with.
Plagiocephaly develops when an infant’s rapidly growing head attempts to expand, and meets some type of resistance— either prenatally in the mother’s womb, or more commonly after delivery because the back or side of a baby’s head is pressed against a mattress, car seat or other flat surface.
This condition affects many infants, especially since the widespread introduction of the “Back to Sleep” campaign which recommends that babies are placed to sleep on their back (supine sleep) that was introduced in 1994 and has made significant inroads to reducing the number of SID’s (Cot Deaths), by an estimated 46% in some countries. However, the by-product of the supine sleeping is a significant increase of FHS which is now at epidemic proportions according the AAP (American Academy of Paediatrics) affecting nearly 50% of all baby by the age of 2 moments. (www.aap.org, 2013).
Further to this, babies suffering from Torticollis are also at risk of developing FHS due the nature of the condition, which is a tight or shortened muscle in one side of the neck causes the head to tilt or turn to one side, resulting in the infant resting its head in the same position.
UNIVERSITY OF TRINITY COLLEGE RESEARCH
In collaboration with world renowned University at Trinity College in Dublin, ClevaMama® carried out a comprehensive study on Deformational Plagiocephaly or Flat Head Syndrome. This research led to the development of ClevaFoam®, the only non-invasive aid proven to help in the prevention and correction of Flat Head Syndrome.
Researchers at Trinity College Centre for Bioengineering conducted a biomechanical analysis of contact between an infant skull and different support materials during bed rest. ClevaFoam® was found to reduce the pressure on an infant’s skull which aggravates flat head syndrome by up to 50% and increase support by 80%. The study found both lower stress distribution on a baby’s head and lower strain energy density when using ClevaFoam® products.
FREQUENTLY ASKED QUESTIONS
What is ClevaFoam® made of?
ClevaFoam® is made from low resilience polyurethane foam.
Is ClevaFoam® the same as memory foam?
No, they share many features but have one great difference, namely the cell structure. Standard or normal memory foam is usually a closed cell structure which makes it heavy, dense, with reduced airflow causing it to retain and build-up of heat. ClevaFoam® is made with an open cell structure thereby making it lighter, more breathable, with reduced heat retention.
What age is ClevaFoam® suitable from and to?
ClevaFoam® products can be used from birth, with the upper age limit depending on the product ClevaFoam®
is used in. For example, the ClevaFoam® Baby Pillow can be used from birth but the Toddler Pillow is not recommended before 12 months. The ClevaSleep® Plus Elevated Support is also made out of ClevaFoam® and can be used until the baby starts moving in their sleep, usually at around 5-6 months (this will vary from baby to baby).
Is ClevaFoam® washable and if so how?
Hand wash using a mild detergent, allow to air dry on a flat surface.
Is ClevaFoam® breathable?
Yes, because of the manufacturing process and the open cell structure ClevaFoam® is breathable.
Is the cover washable?
Absolutely! The cover is like any other pillow case and can be hand washed according to the instructions on the
What material is the cover?
This varies by product, see product information for details.
Are all ClevaFoam® products lined?
Yes, all products have a lining. Depending on the product, some are waterproof and some have structure covers.
CHANGE TO THE TREATMENT OF DEFORMATIONAL PLAGIOCEPHALY DP
In recent years the use of orthotic helmets have been used to correct the symmetry of infants heads and increasingly surgery has been conducted. A recent study published in the British Medical Journal into the use of orthotic helmets and bands used by infants from as young as 6 months and for up to 23 hours a day for a typical period of 3 months shows that these do not work and the therapy results is so insignificant and the use of them has been discourage. (BMJ, 2014). In addition, the report also states that infant found them uncomfortable and parents found them difficult.
A certain amount of prone positioning, or “tummy time,” while the infant is awake and being observed is recommended to help prevent the development plagiocephaly. This will also facilitate development of the upper shoulder girdle strength necessary for timely attainment of certain motor milestones. Avoidance of prolonged placement indoors in car safety seats and swings should be discouraged.
Dr Genevieve Keating reports that “Children who have less interference to their nervous system have a better chance of making sense of their world and their place in it. They have a better opportunity to develop good motor patterns and balance, good emotional regulation and better learning strategies for the future.” (Keating).
This is one of the main reasons why Prof. Michael J Earley, a Craniofacial Surgeon from the Children’s University Hospital in Dublin has endorsed ClevaFoam® by saying “Having worked with Trinity College on this product, I am all in favour of this device as craniofacial surgery is a last resort and prevention is better than cure.”
CLEVAFOAM® EXECUTIVE SUMMARY OF REPORT
Deformational plagiocephaly is a medical condition, common for infants, describing local flattening of regions of the skull due to persistent localised pressure. Incidence has risen dramatically since the advent of recommendations to place sleeping infants on their backs as a preventative measure against sudden infant death syndrome. Although several treatment options exist there is scope for utilisation of passive devices during the early weeks and months after birth when infants are more prone to development of the condition due to relatively low levels of activity.
A study was undertaken to investigate the use of a polyurethane foam pillow (specifically a ClevaMama® ClevaFoam®) as a means of reducing contact pressure to the occipital region of an infant skull during supine bed rest. Preliminary characterisations of (i) the ClevaFoam® used in the pillow and (ii) a generic infant mattress were carried out to define relevant support conditions for the desired analyses. A finite element model of an infant cranium was constructed, taking account of relevant structural features for the analysis of skull contact behaviour. Simulations of the skull were performed for (i) normal bed rest on the generic mattress and (ii) resting on the ClevaFoam® pillow, which was in turn supported by the mattress from (i). The foam and mattress were successfully characterized for the purposes of the study.
Simulation of the two bed rest cases predicted that use of ClevaFoam® would reduce the mean contact pressure in the occipital region by increasing contact area and conformity. Furthermore, local tissue loading was also predicted to decrease with the use of ClevaFoam®. Predictions of the study were within range of values reported in the literature.
In conclusion, simulations of supine rest of an infant cranium in contact with (i) a generic infant mattress and (ii) a ClevaMama® ClevaFoam® Baby Pillow supported a hypothesis that use of the ClevaFoam® can reduce mean contact pressure at the occiput by increasing contact area through greater conformant deformation.
Analysis of the deformation of each model (Fig. 13) shows that the ClevaFoam® model deformed more than the stiffer case of only the mattress. Furthermore, greater contact area between the cranium and its support was predicted for ClevaFoam® support condition (Fig. 14) — 2,959 mm2 for the mattress and 5,644 mm2 for the pillow. This increase in contact area for the pillow support leads to a reduction in the contact pressure (i.e. the contact force per unit area) since the force (i.e. the gravitational load, which was 8.55 N) is the same for each model. Thus, the mattress support was predicted to apply an average contact pressure of 2.9 kPa to the skull while the pillow applied an average pressure of 1.5 kPa.
A benefit of using the finite element method is the ability to predict internal loading and deformation of the tissues. Two measures of loading were examined for the two models: von Mises stress (indicative of the forces generated within the tissue) and strain energy density (indicative of the energy of deformation). Contours of stress (Fig. 15) show that stress was not distributed uniformly within the contact region. Local concentrations were predicted around the suture regions for both models. In particular local stress in these regions was up to an order of magnitude higher than the man contact pressure. Furthermore, a larger region of highly loaded tissue was predicted for the occipital region of the mattress support. This trend was more pronounced when examining the strain energy density of the exterior cranial tissue (Fig. 16). Both stress and strain-energy density were more localized to the sutures for the pillow support condition. In general, stresses were relatively low (< 25 kPa) in the occipital region of both models.
In conclusion, simulations of supine rest of an infant cranium in contact with two different supporting materials, (i) a generic infant mattress and (ii) a ClevaFoam®, supported a hypothesis that use of the compliant polyurethane foam can reduce mean contact pressure at the occiput by increasing contact area through greater conformant deformation. This study represents a first step in determining the local mechanical environment in the tissue of the contact region for an infant head resting in a supine position. The ability to study this mechanical environment opens the possibility of further study of the role of mechanical loading in the development of deformational plagiocephaly.
Cranio-Facial Specialist Prof. Michael Earley said of ClevaFoam®, “Having worked with Trinity College on this product, I am all in favour of this device as craniofacial surgery is a last resort and prevention is better than cure.”
Commenting on the research findings, Fellow Alexander Lennon from Trinity College said;
“There has been little study so far into the biomechanics that cause deformational plagiocephaly. We believe this research is an important step and goes a long way to advancing our understanding of potential mechanisms and treatments for Flat Head Syndrome”
